Slider Windows in Calgary: All You Need to Know Before Installation

Although slider windows are not as efficient as casements, they are still a very popular choice with homeowners in Calgary. What sliders lack in performance ratings compared to crank windows, they very well make up in their price.

And even though they are a cheaper option, most slider windows still meet climate requirements for harsh Canadian winters, and can be considered efficient.

The trick lies in figuring out which company’s windows do meet the necessary requirements, and which company’s windows fall short.

These are the key points to keep in mind about slider windows:

• Although slider windows don’t perform as well as casements, they cost less and still provide acceptable levels of performance.
• When comparing slider windows consider BOTH their heat loss conductivity (U-Factor) and energy rating (ER) for a true sense of how the window performs.
• Because slider windows are operated manually, proper operation is crucial to longevity and performance of the window.

Sliding Windows vs. Casement: Ultimate Comparison

Slider or casement windows in Calgary, or maybe, tilt and turn windows. What should you get?
As we mentioned above, slider and casement windows differ in performance levels and price. But why? A lot of it has to with how these types of windows were designed to operate. A big area of heat loss in any window is the place where the moving part meets the frame. In sliding and hung windows that space is made more efficient with the use of fibre weatherstripping.

Because casement windows open at an angle relative to the frame they can also use weatherstripping to fill the gap in a closed position. But a far more effective component utilised in modern casement windows are soft compression seals. When the window is closed the seal evenly fills the space between sash and frame making for an airtight unit with superior performance ratings.

Another performance variable is the difference in sash size. Because casement windows only have one sash, they only have one insulated glass unit.

Even in single slider windows, there are still two sashes which need to fit into the depth of the window opening. The individual sealed units in slider windows have to be much thinner and are therefore less efficient than a single, bigger sash in casement windows.

Ecoline Windows Reviews

We had 4 companies quote our window project and Sergey was the most informative of all. I appreciated the YouTube videos that he shared to help understand the options. He was clear with timing expectations. I also appreciated the project updates. Matt and his crew worked very hard to get everything installed in the 2 day window. They were polite and did a fairly good job cleaning up. We are excited to have new windows and happy with our decision to choose Ecoline.

Great service! Our windows were 40 years old and needed replacement asap. Our windows would get foggy in the winter and let in draft. Now that we have new windows from Ecoline, our house looks and feels better. The people working here are friendly and knowledgeable. We weren't sure what we wanted but our saleswoman Kate helped us every step of the way and explained the options clearly. We are so happy with our new windows!

This is the first time I have used this company.Both the installers were very nice and professional. They did a good job. Thank youAlexi for keeping the place clean while you worked and making sure the job was done well.I was surprised that MDF casing was used . I expected PVC or wood .. wish I had known earlier. My previous window installers used wood and I guess I assumed they would too .I would also like to acknowledge Vlad the sales person for keeping me informed and reassuring me regarding the work they do as I was concerned about the company payment policy of paying on delivery and not on completion We were happy to have worked with Vlad as he is very knowledgeable about windows.

Sergey is knowledgeable, friendly and continues to be helpful in the process of acquiring a new bay window. Thanks so much! The crew of Alex and Jack came and installed the new Bay Window. They did a fantastic job, were helpful and knew exactly what was best for this particular installation. We couldn't be happier about the work done. Thanks so much to them and Ecoline Windows.

I am very happy that I chose the “Ecoline windows and doors” my experience with them was positive from the very beginning of the process until installation. Sergey, the sales rep was knowledgeable and helped me choose the right windows and doors for me, the installers were very friendly and polite, answered all my questions patiently. All in all they’re amazing. The products are good quality. Most importantly, I am very happy with my 10% cash back from Costco Canada since they are in collaboration with Costco.

Our house is 25 years old. As we needed to replace the windows, we started to shop around. As we got to know Ecoline, our hearts were warmed and drawn to Ecoline . It has been a delightful journey. I feel as though we have been given a brand new house. The various staff we connected were most friendly and helpful. We were truly touched by how the installation team worked in harmony and with pleasant energy. Our house was transformed in one day! Amazing! We will surely recommend Ecoline to our friends and relatives!

This is a great company to deal with from consolation to final installation. Dimitry did an thorough job explaining all the window options, low-e coatings, why he'd recommend each on for areas in our home.Fast forward to installation day. Installers were friendly, did a great job on the installation. They were courteous, made sure that they covered any transitions areas to keep the floors clean, and thoroughly cleaned up after they were done. The install was top notch, and other than the paint touch ups for the interior trim nail holes, you'd never known that they did a remove and replace.The installer walked us through the operation of the windows, gave us a visual of all the work they did, and even as they were packing up after completion, came back in for "one final tweak" to one of our double hung windows as he thought it was not gliding as smooth as it should during the demo.When it comes time to replace any additional windows, they will be the first place we call. As a final note, the fact that Costco uses them as an installation partner carries a ton of weight on how they value the quality and workmanship of Ecoline.

Alex and Jack did good quality work. The window is good, easy to clean as you can open in 90 degree for cleaning purposes.Selecting 4 stars because of miss-communication/explanation. When estimator arrived and ask if we wanted PVC casing or MDF we selected PVC. But we didn't know that the corner connector will be looks as is on the picture, which I don't like it. Another downside is that right side of casing is not fully covering originated casing and now I had to do repair job. Instead to instal wider casing from the beginning I had 2 options, buying a new ones - wider or doing a repair wall.

We are very pleased with our new windows and doors. The Ecoline crew was professional, respectful, and clearly knowledgeable in their roles during installation. Sergey Dobrynin led us through the process from start to finish. His attention to details made sure the end results looks amazing! We immediately noticed the difference the high quality windows and doors make in keeping out the cold.

I first used ecoline in 2019 to replace 4 larger windows in my home. Sergey Teplyakov took great care of me and ensured I got their best discounts. I called on him again in 2021 to replace a bathroom window and - once again - secured me the best deal. Admittedly, the bathroom window was a tiny bit smaller and I had to fill a small gap between the window and my drywall but in the end it looks great. Both times, he helped ensure that the installation met my expectations. A detail to watch out is the casing style - you’ll want to ensure this matches your existing casing. Ecoline also met our condo design guidelines and correctly matched our exterior colour scheme. I’m glad I took the leap and upgraded my windows with ecoline. Ask for Sergey!

Matt and his team were absolutely outstanding. They were not only highly professional but also incredibly polite and attentive throughout the entire process. From the moment we interacted, they made sure to address all my needs and concerns with great care and efficiency. Their expertise and friendly demeanor truly made the experience enjoyable and stress-free. I couldn't have asked for a better team.

Ecoline windows installed a beautiful patio door replacing an old French door set. The installers who were experienced and totally professional did an outstanding job removing the old doors and installing the new one. Nick Covali and the project manager was extremely helpful with any small issues that came up. We would highly recommend this company to any one who is looking to order or replace existing windows. This company is highly professional and extremely honest and very competitive. By the way the entire job was completed in four hours.

OMG so much about this company I loved!! From the consultation to sales, ease of keeping in touch for questions and some changes we had Vlad was there for us and awesome. On the day of installation they were here on time they had a nice big crew as we had a huge job, they were very professional laid down all kinds of mats so that they wouldn't get our floors dirty they were very knowledgeable about their job and the work that they needed to do. The cleaning behind their work was Immaculate I can't say enough about how much they cleaned up after themselves I give five stars to this company the fact that it's backed by Costco and I feel safe that if anything should ever happen down the road their work will be warrantied. The windows are beautiful, and my new door rocks!!! THANK YOU ECOLINE your work is amazing.

Stage Windows by Ecoline Windows provided excellent service from start to finish of the new window installation in my home. I found a sales rep at Costco which explained the service provided. From the initial consultation to the final installation, all employees of Stage Windows were very professional, knowledgeable, and conscientious. The crew that came to install the windows were extremely skilled and competent. The windows look amazing and the install areas were left in excellent condition.

Ecoline Windows and Doors are to go to for windows replacement(s)! Project Manager Mo Saidi is awesome to deal with our quote and suggestions. On the day of installation, crew leader Michael and his crew are kind and friendly to deal with. They did a great job and left not one small mess behind.

I couldn’t be happier with the service I received from Ecoline Windows! They recently replaced three of my windows, and the entire experience was top-notch. From start to finish, their team was incredibly professional and punctual. Alex and Jack, the installers who handled my project, were outstanding—they went above and beyond in every aspect. Not only did they complete the installation with precision and care, but they were also friendly and even took the time to play with my animals, which was a delightful bonus!The attention to detail was impeccable; they cleaned up thoroughly after themselves, leaving no mess behind. It’s rare to find a company that combines exceptional workmanship with such personable service. If you’re looking for a window replacement company that truly cares about their customers and delivers excellent results, look no further than Ecoline Windows. Highly recommended!

We bought these windows through Costco. The installers did a great job and were very professional. I waited for a very hot day before I did my review. The difference in the house temperature was amazing. Very glad that we got this done with Econoline.

No problems what so ever. Right from the rep that helped us choose the window, to the team that did the installation, I couldn’t have asked for more. They were all friendly, courteous and professional. The product itself is wonderful. Thank you all for making this a pleasant experience.

I recently had Ecoline Windows install new windows and sliding doors in my home, and I couldn't be happier with the results! From start to finish, the entire process was smooth and professional. The team was knowledgeable, answered all my questions, and provided excellent advice on the best options for my home. The installation was quick, clean, and done with great attention to detail. The windows themselves are top quality, and I've already noticed a difference in the temperature and noise levels inside my house. I highly recommend Ecoline Windows to anyone looking for high-quality windows and outstanding customer service.

Our experience with Ecoline has been first rate. We were provided timelines and expectations for the first day, the installers came on time, were very attentive to my questions, were studious with leaving the house tidy each day, and most importantly, did top-notch work. Our house is completely transformed. I am so happy with our experience and will refer everyone I know to Ecoline. Fabulous customer service!

I ‘ve just had our old windows replaced few days ago. The new Ecoline Windows are great! The house looks like a new one…. It is so easy to wash them now with their ‘wide open’ feature.The crew Matt, Nick and Vlad are amazing!! They have replaced 17 windows and the entrance door in 2 days!! They are very professional and know what they’re doing. Our old windows/frames were hard to remove and they had to be very careful with the wooden siding as it was breaking easily due to its age:))). They’ve sealed, fixed and painted all the brakes and scratches on the siding around the windows so our house looks really great outside. I love the casing and the total finish!I would totally recommend Ecoline Windows to everyone!! Having this crew was a pleasure! Very kind, polite and professional!!

I had the pleasure of working with the Ecoline team for the installation of my new home windows and doors, and I couldn't be happier with the results! Matt and his crew were not only incredibly informative, polite, and friendly but also a stellar team of professionals.Despite my 150lb dog's constant supervision attempts (he loved to "help" by napping on their tools and blankets), the team remained efficient, tidy, and considerate throughout the entire process.As for the windows, they're simply amazing! With every window and door replaced, my house has transformed into a peaceful sanctuary. I can finally enjoy quiet moments without the noise of the city bus or neighborhood hot-rod disrupting the peace. Plus, the temperature in my house has finally stabilized, making every room comfortable, AND my windows actually OPEN! Oh Happy Day!I can't thank the Ecoline team enough, especially my fantastic install crew, for making this transformation possible. They were the right choice for our home, without a doubt. Before working with Ecoline, I hadn't realized that good doors and windows are more about a good quality of life and less of a luxury. 100% recommend!

From quote to service we are deeply pleased to have done business with Ecoline windows.Their pre-sales is done in a consultive way and they helped us find the best option for our needs.The crew onsite lead by Matt were on time, very professional and left everything clean and neat.Thanks for the great job.

I purchased my windows through Costco and have no regrets. They keep to schedule and always keep you updated. They also inform you during the quote and financing process of all the terms, as well as what federal grants + interest free loans you may qualify for.The products are also very high quality. And reasonable prices as well. If purchased with Costco and under federal grant, they clearly show the potential savings to your investment. My project manager Mo Saidi always stayed up to date on the project and kept me well informed. He also offered me a 3 month grace period interest free and no payment for financing, which gave me time to get the funds for the federal loan after the installationI would highly recommend going through Costco and using Ecoline Windows

I recently had the pleasure of working with Ecoline Windows, and I'm over the moon with the new windows and doors they installed in my home! Not only do they look fantastic, but they've also made a noticeable difference in insulation and security.A big part of my positive experience was thanks to Stanislav, the project manager. He was incredibly helpful, paying close attention to all my needs and ensuring everything went smoothly from start to finish.The installation team was also fantastic—friendly, efficient, and detail-oriented. They left my home spotless after the job was done.Overall, I can't recommend Ecoline enough. If you're in need of new windows and doors, they're the ones to call. Thanks again to Stanislav and the whole team for their outstanding work!

Starting from requesting a quote online to the installation Ecoline was incredibly easy to work with. We were quoted reasonable rates (for a whole house of windows!) and the staff we interacted with were always pleasant and open to our questions. They were happy to show how the measurements were taken, our options for framing and what would be more energy efficient for the Greener Homes ****** Window production was done pretty quickly and installation was booked for a whole day but only took half a day. We've had these windows for about a year now and have really noticed the difference with no moisture inside the home and sound reduction from outside. We loved the process for the windows so much we also got our blinds from them!Both sales representatives for the windows and blinds brought samples, were mindful of our budget, and listened to what we wanted when exploring style options. I highly recommend them if you are looking into window or blind replacement.

We contacted with ecoline windows in November. Windows were replaced on January. Quality of windows is good, it is very warm and quiet in our bedrooms now. Installation was done fast and on time, they cleaned and vacuumed everything after themselves and took the trash with old windows. The only thing that we didn’t like is that there was a small issue with dimensions, so the new windows are approximately 1” smaller than the old ones, which doesn’t make any difference. So, installers added wooden pieces all around. Sealed everything from outside, and inside looking great!

Ecoline replaced 26 windows in our home in December 2023. The initial quote was very competitive, and the lengthy warranty was a definite selling feature. Installation took a bit of time, but the installation was very well done. It took 2.5 days, I've noticed no issues, and the windows look nice and reduce the outside sound. The installers were polite, professional, and quick. Cleanup was thorough. Overall a very good experience.

Ecoline Windows was awesome to work with from the beginning estimate to the finished installation. Alex came and discussed window options and was happy to answer all questions! Ecoline was priced fairly and we decided to go ahead. They helped us with the Greener Homes Grant process. The installation process was fast and efficient, they put down sheets and kept the areas clean. After installing the windows they showed me how they worked and how to clean them and I inspected all windows before they left! I am so happy with the windows, they are so nice!!! Would definitely recommend!! Thanks Ecoline!!

I can't say enough good things about Ecoline Windows and the people that work there. From the start, the sales rep came in and explained everything, gave details on how the windows worked and was very responsive to any questions. The windows came in and the crew installed 17 windows and a patio doors in one day, they were friendly and courteous. The window hardware is so easy to use and I like their locking system. Even after they were installed, I had a nick in one or screens, they came back promptly and fixed it. I have had such a good experience.

Had Ecoline in to replace my upstairs windows including double-hung, slider and picture as part of the Canada Greener Home program (8 in total). Minus some minor factory build delays the process from initial visit to install was very fast (The install was completed quickly, in a single afternoon which was great as it was during a cold snap). Have been quite happy with the professionism from all staff involved including those involved with my service request related to two of my double-hung's not functioning well (They had to replace faulty coils in each which apparently was a result of a bad batch that impacted a few households).So far so good (Have now had installed a year) with the only issue being the coil issue which was obvious when I first started to use the top sliding windows in the spring. The triple pane has provided a definite improvement in temp swings during the summer and winter so am very happy with that.Overall really happy with the product and service.

Got a bunch of estimates and decided to give them a call to try my luck. Tony came to give me an estimate and was very honest and helped me understand the process and their products. He gave me a very good price. He was very respectful of my home. I definitely recommend.Edit: It has been a few months and the windows have been installed by a gentleman named Matt. Him and his crew did an amazing job. Very friendly and polite.Would recommend(again).

We had all of our windows on the top floor of our house replaced by Eco Line and they were very professional, on time, answered all of our questions we had without any issues and most importantly they were very nice and clean and made sure that no damage was done and that no one left until everything was installed properly, safely and we knew how to close the windows to ensure they sealed.The pre installation process was painless, they were easy to talk to and helped us to understand all of our options for the different kind of windows we could have.

Ecoline installed 5 windows for my house in August 2023. I booked an initial visit in May, the sales person was really professional, arrived ahead of our scheduled time, very familiar with their products, promotions and procedures from initial visit to completion of the installation. During the process, a lot of advices have been provided whenever I need clarification and help. During the process, I changed my order a few times, he was very patient and understood my situation and arranged the changes with no issues. The 5 windows were installed in one day and the installation went very smoothly. I am very satisfied with their service and certainly will recommend others to take this happy journey as well!

We are very pleased with the installed windows as well as the vinyl casement installed inside to finish the job. The crew was very fast and efficient and the cleanup was excellent. This is the second time we worked with Ecoline Windows. From the quote to predelivery to completion the team was excellent at communicating with us. Definitely recommend this company.

Really pleased with my windows. I liked how the company was extremely prompt with contacting me after I filled out the contact form on the company website. Then, the advisor was professional, on-time, kind, and didn't waste my time nor rush me or pressure me to buy anything. I wanted to think about my options first, and he completely respected that. This was not the case with other companies. Ecoline sets the bar for windows in Red Deer for sure. As for installation, it was thoroughly assessed prior to and they did a great job installing the windows after. I can notice the difference in the house with the heat retention and it just seems brighter and cleaner looking both inside and outside. I opted to get the windows as part of the greener homes initiative and it was very clear on what to expect with the types of windows that I chose. Definitely recommend!

Ecoline were awesome to deal with.I initially dealt with Alex who came and completed my estimate. Oksana at the office scheduled my install and then the team who completed the installation were amazing. Ordering to install was about 10 weeks which was shorter than I had expected.The team arrived on time on the day of the install. Covered all my carpets to avoid any damage from coming in and out. Vacuumed up the area once they were done. I work from home full time and was able to continue working with no interruptions.I’m so happy with my new door! The old one was likely original to the house and was literally falling to pieces!I highly recommend Ecoline

Quick and professional, obviously skilled at their trade. We would recommend Ecoline.

Very happy with the final product and the majority of my experience. The project manager Uriel was excellent to deal with.The windows look very good and were a great deal. I've also received multiple compliments about my front door.My only concern was the punctuality of the installers. Out of the 3 times they came by to do installations, they were late by at least a couple of hours each time. On the first day, they were supposed to be by in the morning, and didn't show up until after 3. Another time, they said they were going to be by at 11am, and at 4pm, I got a text saying that they couldn't come that day. They were great when they were here and did excellent work, but that lack of punctuality is unacceptable. I would have given 5 stars otherwise.

Ecoline were excellent to deal with from start to finish. The sales rep provided us with a detailed and competitive estimate after a comprehensive interview. She was well informed and made excellent suggestions. Thank you Anastasia. Ecoline provided assistance on government rebates available and kept us informed on the progress of our order. Delivery was on schedule and as expected. The installation was quick and clean and the windows fit the openings with appropriate easement for insulation and caulking. We love our new windows! We would definitely recommend.

Had all of our windows and sliding doors replaced by Ecoline, with triple pane. I was very impressed with the salesman (he came back a few times to insure we got the right opening directions) and installers they were very professional and left the area cleaner than when they arrived. Did not realize how bad the old sliding doors were, plus the new sliding doors have tempered glass We have had our first snow and I have already noticed the difference. Windows made in Canada for Canadian weather.

Ecoline replaced my basement windows last month and they did an amazing job. Their project manager, Uriel, was very experienced and knowledgeable.

Ecoline replaced majority of the windows and doors in our home in Canmore in Spring 2023. They did a fantastic job, were great to work with, and easily the most price-competitive in this market. We noticed a very big difference in temperature control in our home over the Summer months, and look forward to keeping more warm air in during the Winter as a result.Highly recommend Ecoline!

Graham Silk

I had some misgivings when the contract required full payment before installation but this was unfounded. The installers arrived on time ,were very amenable, worked very efficiently and quickly and did an excellent job. The windows look great and I was totally happy with the outcome. I will require other replacements in the future and Ecoline is at the top of my list for supplier/ installers .

I just had Ecoline Windows out to quote window replacement as we have experienced water damage and leaking since the purchase in 2021 of a 10-year old home. This was a free in-home estimate which was easy to book, and I received reminders leading up to my appointment. Project Manager (Uriel) was very knowledgeable and explained thoroughly my options and was able to answer all my questions. There was something that caught his eye which made him check the exterior casing and he was able to immediately determine my issue is almost certainly a step missed during the build process, and does not require window replacement. Because of Uriel's knowledge and honesty, I have likely been saved thousands of dollars. I felt in necessary to leave a review to commend this company on their honesty and expertise. If I need any assistance with windows in the future Ecoline will be who I call without a doubt. Thank you Uriel!

I’m very pleased with our new windows from Ecoline. We had our consultation with Tony who explained all the options and help to choose windows, he was very knowledgable and informative, great communication from start to the end.Installation was completed 3 weeks ago by Matt and his crew, who did great job, Matt was professional, didn't rush and made clean job, he took his time to go over all the windows and explained how to take care of it. I'm very happy with entire process and definitely will recommend Ecoline for your new windows, especially Matt's crew as installers

It was my second time using Ecoline Windows. Everything went pretty well - the installation team were great and our house can be a bit difficult (it's 110 years old so there are always fun surprises - like this time they had to basically rebuild the whole door frame which I'm sure was a pain and they didn't plan on it). Sales and installation teams were both really pleasant and helpful. The only things I didn't love were that we asked for a door handle but not a lock from the salesperson but the message got misunderstood and the installers thought we were providing both (but I did just go to Home Depot with them to pick up the lock and handle!) and then I didn't like that I had to pay the whole balance before they would start. Seems like you should be able to hold back some of it at least and pay once the job is done.

We had all 21 windows replaced and they look fabulous. Kowtow and his team did a great job. They were professional and had them installed in one day. In addition they made sure they cleaned up after the job was done. All I had to do was enjoy my new windows. Thanks Kowtow and your team as it made my decision going with Ecoline the right one.

I would give this guy a 5 star for doing a great job on my windows and door project. The salesman, Mo Saidi is very diligent , knowledgeable on his job, very patience guiding and helping me to understand all the details of this house project, which make me decide to get my windows from Ecoline. Customer service is awesome and excellent. During the installation, the crew are very professional and respectful. Anton and Eric and crews did a great job installing all the 14 windows in a day. They are very fast and very sure of what they are doing. Installation turn out great and superb.

We had Ecoline windows come in and replace all of the windows in our house. They were super professional and we love the work they did. The windows look fabulous and we are looking forward to all of the money they will save us with heat costs in the winter and cooling costs in the summer. Thank you Ecoline for taking such good care of our house.

We are very happy with our new windows installed by Stage/Ecoline using our Costco membership. The consultant Dmitry was very thorough and communication has been excellent. The install was sooner than we expected and the team that came to our house was outstanding; they were professional and comprehensive it getting the windows installed and cleaned up completely as they progressed. I would highly recommend this service and of Costco rebate is also a nice benefit too.

I very pleased with our new windows from Ecoline. We had our consultation with Tony who explained all the options and help to choose windows, he was very knowledgable and informative, great communication from start to the end.Installation was completed 3 weeks ago by Matt and his crew, who did great job, Matt was professional, didn't rush and made clean job, he took his time to go over all the windows and explained how to take care of it. I'm very happy with entire process and definitely will recommend Ecoline for your new windows, especially Matt's crew as installers

We had our consultation with Frank and we were shown different examples and options. He was very knowledgeable and informative making the decision process easier, and guiding us through. We then had our installation two weeks ago, the process was quick and the installation crew made clean up afterwards. Right away we noticed the difference in the temperature inside the house. It is much warmer now and the windows look great! The windows are also very easy to clean. We are very happy with the process overall and the results speak for themselves. We would recommend Ecoline for your window installation.

Def 5 stars +. Great company. Best windows I have been getting so far, the quality is top notch in all aspects. Every single piece is expensive and solid. Fittings are very good with metal parts instead of cheap plastic. My room was quite loud before, this was the main reason for an upgrade, it def exceeded all of my expectations. The soundproofing is perfect it is very cozy room now. Also this was the only company who offered this width of opening. Appreciate the help of Vlad Butko, he helped me with all the aspects, and I received very detailed consultation. Would absolutely recommend to anybody who is seeking for good quality product.

From first contact and quote to installation Ecoline Windows provided professional service. I can not say enough about how patient Ivan was with us and our many questions about the quote and contract and how accommodating the installation crew was with our particular family situation. My mother is so pleased with the product and entire experience that she asked me to see if they can do a little more work installing storm doors and window coverings. I will happily recommend Ecoline to others.

Ecoline replaced 10 windows in our house, and we are very happy with the whole process.Ivan took care of us from a sales perspective, was very professional, and answered all our questions (as well as follow-up questions).On the installation day Matt and Max showed up on time, and their work was very detail-oriented and professional. We didn't run into any issues during the install, and they did a great job answering any questions as well as cleaning up after themselves.Would definitely recommend Ecoline if you are considering them, will reach out next year to get our front door replaced.

Ecoline replaced 12 windows in our home. We are happy with our purchase and believe we received good value for our money.From start to finish, Ecoline looked after us. Their website is very informative and one of the best out there. Vlad C took care of us during the sales process and he was excellent, patiently answering all of our questions.Our installation(s) went relatively well. We did have some minor issues that needed to be corrected and these were dealt with quickly and efficiently by Raffaele in customer service.We initially ordered 9 windows from Ecoline and liked them enough to order 3 more. The triple panes made a noticeable difference and these windows are eligible for the Greener Homes Grant ($250 / window). The only surprise we had is these windows can have a grey hue to them when the bright sun hits them on an angle. From looking on-line, this is a common issue with triple pane windows and low e coatings (light reflects off coating). It is not unique to Ecoline and only happens during certain lighting conditions. Not a deal breaker for us, but something to be aware of when selecting glass coatings.Our windows function well and appear to be well made. So far, so good!!Thanks Ecoline!

Vlad C came to assess our windows today and we had the best experience. He was one of the friendliest people I have ever had the pleasure of meeting and I genuinely enjoyed the experience with him. It was just a window assessment but he made us confident about using Ecoline as our window replacement company. He also provided a very thorough quote and walked us through all the different options which really made us feel comfortable with the process. Request Vlad when you are using Ecoline!!! I cannot say enough good things about him :)

Andrew's crew were very professional and hard working. They didn't waste any time on the job and installed 21 windows and one door in 1 day at my house. I am so glad to work with Ecolin window. From the moment I signed the contract they were sending me updates about progress of my order and they help me through my application for Canada's Greener house Grant.

Ecoline was a pleasure to deal with from the minute we got the quote. They were great with communication when we placed the order, giving us an update when requested on the status of the order. The installers were great and friendly. They pay really good attention to detail and were able to preserve our existing moulds around the back door. They were clean and didn’t rush the job. When they arrived, they were given a challenge the way the builder had installed the previous door but were able to overcome obstacles on the day of install. I would highly recommend Ecoline to anyone looking for upgrades products! Thanks again! We are very happy with our new sliding door!

2021 -Ecoline did a fantastic job from day 1 of calling! My husband and I have had some rather negative experiences with other window companies, so it was a huge relief working with Ecoline. We easily got in contact with Ecoline to set up a quote, which was done within days of the first call. Alex Havkin, project manager, came in and seemed to really know his stuff and could answer all our questions. We felt no sales pressure and were given lots of details and shown photos of similar projects before and after. Once we had made a decision on a later day we easily got in contact with Alex and everything was set up super fast and without any confusion or hassle. Ecoline has the best guarantees and really seems to stand by what they say they will deliver, and when. They were actually able to install our windows before the date they assured us they would have them in by, which was a big deal for us.Our windows were installed by Nik, his son Shawn and Chris. Nik did a phenomenal job of running his crew and making sure we knew what was going on and that we were happy with how the windows looked every step of the way. He made sure we were comfortable with himself and his workers and was easy to talk to and ask questions. All three seemed to be super hard workers as they finished a big job in one day (8 large windows), which according to the company usually takes two! Nik went above and beyond in making our house look pristine after; painting stucco after touching it up, perfecting trimming, and ensuring we were happy with the end result and had no unanswered questions. Highly recommend Ecoline and especially Nik and crew for install.Update 2022/05 We had Ecoline (Nik's crew again) install four more windows, finally completing the replacement of all of our windows! They still do a great job! We cannot recommend them enough. If you're having windows replaced get it done right the first time by Ecoline.

Just had 6 windows in our home removed and new ones installed by Nikolay and Dimitri. They were incredibly courteous and communicative upon arrival, and wasted no time in getting started. Throughout the process they kept in touch with issues that arose (mostly due to the age of our home) including moisture trapped in drywall and rotten wood. In both cases, they dealt with the issues for us expertly and helped ease our minds. The speed at which they carried out the removal and install was pleasantly surprising. They also cleaned up afterwards which was particularly appreciated by us due to having our baby in the house at the time. The windows look and operate fantastic, and the materials and insulation used were quality. We cannot be happier to have had these two install our windows and would recommend (and request) their services a hundred fold.

Nick and Dima arrived on time, introduced themselves and set to work. They were very friendly and professional, explaining what they were doing and answering any questions I had. Their work ethic is excellent and they collaborated beautifully on the project. The respect they showed for my home was outstanding, keeping the areas covered and cleaning as they went. Impeccable attention to detail!Refreshingly friendly and thoughtful, a truly great experience start to finish! Five stars all the way

I was in the market for new windows and had about 4 quotes to mull over. I ended up going with Ecoline windows because their pricing was by far the best, the sales process was very good, thorough and modern. The installation crew was amazing as well. I have a large puppy who is overly friendly and they were so patient with him, very polite and of course quality workmanship. All around super happy and I have already referred them to a friend.

Matt and his crew performed a very professional installation quickly and carefully. During the installation work, no damage was caused to existing finishes and great attention to detail was paid to the appearance of the installed windows. Matt left clean windows and surroundings and tidied up as he went from room to room. He also gave good advice on window care and operation. Matt and his crew were very pleasant and went out of his way to make us happy.

Very happy with the service so far. I checked Ecoline Windows initially because of the Greener Home project and the option of getting a rebate. Alexander was very patient and helpful with the quote he gave me, answering all my questions and explaining everything. I changed the plan a few times and he made sure I got the best deal with every adjustment I wanted to make. I ended up changing all the windows in our house, as well as two doors. Max and Matt did a great job with the installation. They installed 16(!) windows in about 8 hours on the first day. On the next day the did the doors and one last window, as well as the finishing work on the outside. The installed windows are clean and clear, I don't need to worry about washing them anytime soon. My contract didn't include framing on the inside which probably saved some time, but still, the installation went much faster than I ever expected! The entire time they were professional, cheerful and friendly. They cleaned up all the dust and debris and when the job was done, removed all the big garbage in under 30 minutes. Extra points for efficiency! Great service and great attitude 👍

We used Ecoline Windows to replace all of the original 18 windows in our 1982-built home. Representative: Vlad Butko was the face of the company for us from start to finish and we were very pleased with his service! Here are some of the highlights:- Received a professional and detailed quote on day one of meeting Vlad. He had some great recommendations for us that we ended up going with.- We added a condition to the contract that all existing blinds must fit the new windows and they did a perfect job with that.- We had received other quotes from window companies but Ecoline was very fair with their pricing. Also, Vlad provided us with details about the government of Canada new windows grant that the other companies didn't. This alone saved us $4,500.- Their supply chain is more efficient so we received the windows a couple of months faster compared to what other companies were telling us.- The inside and outside look great! The biggest difference we immediately noticed was how crystal clear the view was looking outside lol. We underestimated how dull our old windows had become.- There were 2 minor follow-up items that Ecoline had to come back for to finish (including a new window that arrived broken) and they did as promised. Vlad was also exceptional with his communication with us here.I strongly recommend Ecoline to anyone looking for new windows and be sure to ask for Vlad who was an all-star for us!

Very impressed with Ecoline Windows from booking to ordering to install to enjoying the finished product! I requested quotes from 6 different companies in Calgary to provide me windows to meet the Canada Greener Home Energy Program specifications, and this was 1 of 2 companies who could deliver, so that I received the maximum rebate eligible per window. The Ecoline total price was the middle of the quotes, yet I get my rebates, and this brings me below the quote of a competitor. Professionalism all around--Alexander H. was courteous, honest and very professional in the assessment. The booking of appointments was quickly done by office staff. Addressing questions as to when the install may occur was thorough and they were patient with my questions. The installers, Alexei and Slava were very courteous and polite, worked hard to install and get the job done on time, tidying and cleaning debris into piles, sweeping and vacuuming as they left a room. Time of booking to installation was about 4 months. Competition in the marketplace is good, but why waste your time when Ecoline delivered on all aspects?

I am very pleased Andrew and his team, great job done, quickly and professional. I would strongly recommend Ecoline for any windows replacement you need. The install took two full days for 27 windows.The crew showed up on time, everything worked like it should be and cleaned up inside and outside of the house. Once again , they did a great job.Project manager Vlad was extremely knowledgeable about the products and provided a lot of helps during the quotation process.Also say thanks to Apala during the payment process.The window are very solid and the locking system is outstanding.Big thanks to Ecoline.

This is the third time we have had Ecoline installing the windows in our house and they have been very professional every single time. The sales and service experiences have all been great and their pricing is very competitive.This time we had great installers crew working in our house. Nikolai and Misha were quite patient with us and provided us with the helpful information and recommendations. The guys were very professional during the installation and cleaned up after themselves. Thanks for another job well done. We have recommended you to others and will continue to do so.

I am fairly happy that I chose the Ecoline Windows to do my window replacement for the government's Greener Home Grant. The representative was very helpful and informative, not only about the window installation but also on the procedure to claim the Grant. The installer did an overall good job, neat and sturdy. They did a lot of outside work under extremely freezing temperature (-30 C), which was impressive.

I was so impressed with the quality of the windows that Alex showed us, it didn't take much convincing to sign up as we had several quotes and all were similar dollar amounts except that Ecoline Windows were far superior!!! I can hardly wait to get them installed. Alex was also very knowledgeable on the Greener Home Grant as well. I would highly recommend Ecoline!Windows have now been installed, super Impressed! Such fantastic quality and Alex just stopped by and checked every window personally after the install team left. Highly recommend Ecoline Windows!!

I had my windows done today by Sharkey, Andrew, and Eugene. The company contacted me to let me know last week that my sliding patio door would not be ready, but would I like to get the windows in while the weather was nice. I opted to have the windows done, and was charged accordingly, with the balance due for the door when that arrives and is installed.I was given a 9-11am arrival window. They were here about 9:30am, and are in the process of cleaning up now, at 2:30pm. I had 7 windows done today. They look great. The gentlemen were very friendly and competent. My house is a 1990 Stucco house, and of course some of the stucco was damaged when removing the old windows. This wasn't unexpected, and the gentlemen patched the stucco accordingly, before sealing with Silicone.The final price came in lower than I'd expected before getting the quote, and the warranty appears to be excellent. The windows themselves look great, and slide very easily, compared to my old 30 year old ones.Would use this company again, and recommend to others.

We went through Ecoline for a new front door. Igor came to our home to help walk us through the products, the options they had, what would happen during installation. He was very knowledgeable, very patient and kind. We ordered at the beginning of March 2021. The installation date was June 1. The installers were great! Unfortunately the door was installed incorrectly. It opened on the opposite side. I had to contact the service department to advise what had happened. They were great, gave me the information I needed to provide them with. It had originally sounded like they would need to manufacture a door. In August, the installer came back and corrected the the door install. They ended up flipping the door around.Took a long time but I'm completely satisfied and the door looks great!

Ecoline installed new windows in my home a couple of years ago. We have been very happy with the quality and performance of the windows, so we contacted them again to replace a door. The consultation with Alex H. was quick, efficient, and informative, and he took the time to ask about the performance of our windows as well. Their paperless quoting system is an environmentally friendly bonus to this process, and the quote was in my email inbox within minutes. Great experience all around.UPDATE: The new door was installed today. The finish is excellent and Matt and Alex were careful to leave everything very clean when they were done. Very happy with the product and the service; highly recommend.

Just had my Ecoline Windows installed. Could not be happier with the finished product. They are a huge improvement over our old Windows. Vlad was great to deal with on the initial sale and made sure our Windows were exactly what we wanted and did not oversell, but presented all the options. We felt comfortable with the order and the quality of the product. Matt and Hacop installed the windows and did a fantastic job making sure we were aware of the best options. They were quick and tidy. Even made sure any small damage to our stucco was patched and unnoticeable. Would not hesitate to use Ecoline Windows again for next window purchase.

From the beginning of our contact with Alex and his team working with Ecoline to get our windows replaced has been a positive and hassle free experience.Having a newborn at home and getting new windows installed, during a pandemic, was an adventure.The sales representative was unobtrusive, informative, knowledgeable, respectful, and polite. He never pushed us, and made sure we got exactly what we needed at a good price, and they helped steer us in the right direction with the government rebate program!When the Alex’s crew showed up they worked efficiently, cleanly and safely. The entire crew was respectful of our home, our request to take precautions for our infant, and ourselves. We were surprised when extra crew showed up at the end of the day to power through the last three windows.They came back in full force the next day to finish the trim, and complete the job. Even touching up the exterior paint on our home where they had been working.This has been the most enjoyable experience with contractors my family has had. They always had a smile for our babe and even softly sang lullabies when they knew babe could hear them.We are happy! And we have quality windows installed with solid workmanship. Thank you!

We had all of our windows replaced by Ecoline, replaced our sliding patio doors to French doors and even changed the size of one of our windows.Vlad & Igor were the installers and they were GREAT to work with. They were polite, hard working, respectful and all around great guys! They kept everything clean. Vlad & Igor kept me updated through the progress of everything and were attentive to my inquiries & requests.The new windows look FANTASTIC. We are both so happy with how everything turned out. The French doors are beautiful. Quality care was put into each install.I would not hesitate to recommend Ecoline Windows to anyone.Thanks to the Ecoline staff and a BIG thanks to Igor & Vlad!!Tina B

Ecoline windows provided a very competitive price for an excellent product. The installers were amazing, on time, fast, productive clean and courteous. I would recommend them. I would give five stars if the company did a normal deposit of 20% on order and 50% of balance on arrival of goods and then full payment on job completion. They were asking for the entire bill to be paid up front on arrival of goods. We had to argue with them a bit to get the security we needed with the 50% hold back until job completion. I get it, maybe they have been burned before but we do not work that way. All worked out fine they are paid in full and we have new windows! Thanks Ecoline!

'Wow' factor from start to finish. Ordering was very easy, pricing beats the competition, and the install went great (thanks Nick!!!). The windows are very solid and the locking mechanism is outstanding; one lever to lock/seal it all around (casement crank out window). Scheduling everything was calls and/or text so nothing was ever missed, and follow ups were great too.

Highly recommended

Shane and crew were awesome. They were very professional and efficient. Great care was taken with all steps. I work from home and they worked quickly and quietly as possible. Answered all questions and gave a great run down how to work with windows. I never felt like I was in their way while following the day pictorially for my husband who was out of town but I made sure to capture only pics while they were busy elsewhere. It was a comfortable day and I so appreciated the help with moving the couch. All in all a great experience and so happy with the new windows and looking forward to the benefits they will bring to our house

Put up with my 40+ year old patio door for three years. So happy it finally got replaced today. Really excited to have a door with energy efficient glass, sliding screen, and a kick lock (no longer have to use a stick at the bottom like the old door). From quote to installation, the Ecoline Team has been a pleasure to deal with. I unexpectedly needed the door early and they went out of their way to coordinate production and install the door AHEAD of schedule. Really impressed by the workmanship and clean up by Andrei and Sergei!! There was a slit in the screen from transportation but the Job Supervisor was on top of it and already submitted a repair request before I noticed. Thank you very much Ecoline for providing affordable quality products. Will definitely keep Ecoline in mind for future door and window replacement projects.

We are very happy with Ecoline. We got all our windows and doors replaced and they did a fantastic job. All the windows and doors came in correct sizes - customized as per our needs. Our home's heating has become considerably better after installation and all the products are working very well. I had called 4 other places for quotes as well and Ecoline was the best priced and great quality. Alexander is polite and understanding. The installers were very good at their job and quick!

We needed to replace windows in our home and had requested quotes from various window companies. We are a retired couple and are on a limited budget.We had various companies come and give us quotes but not many were as efficient and thorough as Alex from Eco-Line Windows in actually educating us about the window we would be installing. He was the only one that brought in a model window to show us the actual window! He showed us how the mechanics of the window worked and explained the ins and outs of the window. He was very thorough with every aspect of the process if we were to buy the window from Eco-Line Windows.He then left us with a quote. Sent us a follow-up email and telephone call.We were so impressed with his professional approach to how he conducted business with us, and he definitely was not the cheapest, but he got our business!Thank you Alex for the help you gave us in choosing our windows.

Update: Mar 2021,New windows installed Dec 2020 and so far all is working very well. Less noise and much better insulation provided. We really put the windows to the test during a cold snap in February. We had to call back a technician (Dmitri) to adjust some frame foam insulation but otherwise extremely happy with the product and service-----------------------------------------------------------------------------------So far their consultation and measurement teams have been great to work with. Alex and his assistant/trainee Ori went over all of our options for the quoted work and were very informative about the whole process of the window replacement (we are getting 15 done total). Even had some demo units to show the hardware, inner workings and insulation from a cross section. The fact they make their own windows as well provides a peace of mind and should alleviate any issues down the road should we have any. We were so impressed we booked their service on the spot! A week later Victor came and did all the measurements to confirm for the installing crew. We can't wait to get the project started and we are confident they will maintain this 5 star rating even after the window replacements are completed. ( review to be updated upon completion of install)How long did most people have to wait for installation to actually begin? Just curious as we signed our contract early August 2020 and still no ETA on when they are going to start? All I get is Nov/Dec?

Had drafty dusty frosty 20+ year old windows in the back of our home. Installed three new Ecoline windows and what a difference this past winter. Attached is a picture of our new kitchen window - with the wide open design we now have a great unobstructed view of our backyard.We had installed Ecoline windows at our previous home and were very satisfied with them there. They were a natural choice and price was comparable to others.Sales agent was friendly and pricing process was efficient. With the renovation business extremely busy installation was delayed a month or more but they were well worth the wait. They were installed in October just in time for winter. Removal and hauling away the old windows went well. The new windows fit like a great pair of gloves, they all slipped in perfectly even though the kitchen window was very heavy. Reinstalling the interior window casings took some adjusting as they had to be installed exactly where removed to ensure the sill was even.After service for a few paint touch ups took sometime too but the end result is awesome. We've been so pleased we're using Ecoline to replace our front windows this spring.

These guys did an amazing job, from the first time I was quoted to the day of install. I felt comfortable and assured throughout my experience. Everyone I spoke to and met at Ecoline was friendly and respectful. The installers did a fantastic job and the windows look amazing. I will definitely call them back to have my basement windows replaced. Good job Ecoline Windows!

Alex and Joseph attended on time and provided estimates for 3 windows, bedroom , dining room and kitchen. I asked for this company as they had installed 2 external doors, and two large living room windows three years previous. Those installs were done efficiently and site cleanup was excellent. All questions were answered and good advice provided. Highly recommended. Thanks

Well so far so good! The gentleman were punctual this morning and were good and effective at removing two of our basement windows and installing two new ones in a very timely manner. The windows are extraordinary and are vey sharp looking. The men cleaned up nicely and left no mess behind and really concentrated on the task at hand while they were here. I will be sure to do more business with them in the future. Prices are the best in Calgary.

Awesome company! Awesome people! From the initial meeting with Joel to the installation with Artur, everything about these guys was amazing! So much so that I made them come back for more! ;) Great products! Great quality! Great prices! Go Ecoline!! :)

It's not often that one finds a company in Calgary that works so efficiently and provides such a great service at a reasonable cost. My husband and I had one window replaced and two new ones added to the darkest rooms in our house. We were impressed with the work of the Ecoline crew. They were prompt with giving us a quote, helpful when we had complications with the City of Calgary regarding the building permit, and, most importantly, they impressed us with their workers' craftsmanship. We are very grateful to the professional and hard working staff at Ecoline Windows and would highly recommend this company.

Amazing experience with this company! The consultation was simple, straightforward and a breeze. Joel did a wonderful job explaining everything. As well their team established great communication through emails of any questions, paper work, updates on the project and the timeline for the installation. The installation was wonderfully done as well, the workers were friendly, diligent, came at the promised time and got the job done as soon as possible. They were also great at cleaning up after the installation was complete. 10/10 would definitely recommend this company! They take pride in doing the job right and it shows.

We had multiple quotes on the window and doors replacement, but decided to go with Ecoline for the following reasons:1. Our close friends and neighbors have their windows and are very happy with the result, they have recommended, which is very important2. The consultant Alex was very professional, knowledgeable, honest and(opposite of pushy). It was a nice change. He explained how their windows are made, stored, etc, Showed us a government website showing the energy efficiency ratings. His calculations were fast and precise3. Their warranty program and price. Especially the fact that in case of any warranty issues they'll come and do the work, not just give us the materials .I would definitely recommend Ecoline to any of my friends and family. And I will update this review after installation and some time later .

We just recently had windows and doors replace. We had many quotes but chose Ecoline because they were a little less expensive, Canadian made and if there are issues they come out and fix them. The repairs are not contracted to a third party. Alex came out to do the quote and was very professional. He brought the brochure with all the products and we made out choices. When it came time for installation the crew that came to the house was fantastic. They made sure they put down drop cloths to protect the floors and cleaned up when they were done. They were funny and we had a few laughs. The installation only took 1 day and they even showed us how to remove and replace the screens. The only reason I am not giving 5 stars is the customer service. I called on many occasions to be told that I was next in line for a representative and was placed on hold for 15 to 20 minutes then told that I had to leave a message. When we were able to talk to someone they were not able to give us any information. The installation should have been end of September. Customer service had no answers for us and we ended up contacting Alex to find out what was going on. He managed to get the answers for us and about 2 weeks later installation took place. I would definitely recommend Ecoline to any of my friends and family.

Fantastic customer service. Clear communication with follow-up reminders about my free consultation booking. Alex was considerate, friendly and wore a mask while in my home. They have a great software technology to show all aspects of the quote for your consideration and he was sure to review every step of the process, including warranty details. I even got to see a map of all tehri active and completed jobs and felt reassured that they had worked on many houses in my neighbourhood. Highly recommend!

This is the second time we've used Ecoline to do an installation. The first time was windows, this time it was an entry door with a side light. The estimation process was quick and painless. The reason I'm giving 4 stars rather than 5 is because of a delay in the installation. This was not all their fault. The Novel Corona situation has caused delays for other services. It would have been nice if the installation schedular would have been a bit more proactive in contacting us rather than requiring us to call them.Regardless, the installation was done on a day when there was a light snowfall going on. The installers were on time and did an excellent job. There were a few issues they ran into once the old entry way was removed, but they handled it with professionalism and stayed until the job was completed (about 7:00pm).Pricing seems on par with other first-rate companies in Calgary. Because this was the second job they did for us, we got a repeat customer discount. We have some more windows that will need to be replaced and we will be going back to them for the additional work.Highly recommended.

So far their consultation and measurement teams have been great to work with. Alex and his assistant/trainee Ori went over all of our options for the quoted work and were very informative about the whole process of the window replacement (we are getting 15 done total). Even had some demo units to show the hardware, inner workings and insulation from a cross section. The fact they make their own windows as well provides a peace of mind and should alleviate any issues down the road should we have any. We were so impressed we booked their service on the spot! A week later Victor came and did all the measurements to confirm for the installing crew. We can't wait to get the project started and we are confident they will maintain this 5 star rating even after the window replacements are completed. ( review to be updated upon completion of install)How long did most people have to wait for installation to actually begin? Just curious as we signed our contract early August 2020 and still no ETA on when they are going to start? All I get is Nov/Dec?

Kenneth Shears

22:24 03 Nov 20

Just had our new windows installed in Oct 2020. Very happy with them! Alex, our installer was very good, even vacuumed before they left. Someone from Ecoline called during and after installation to see if were satisfied. Recommend them highly.

21:27 03 Nov 20

We've done 2 projects with Ecoline in the past to replace windows and a patio door, and have been extremely satisfied with their service and professionalism. We're currently working with them to replace our front door and balcony door, and the estimator, Joel was again excellent, advising us on the most cost efficient options and giving us good advice. We look forward to having Ecoline replace these doors and they will be our first choice for any future projects as well.

This is only a review for consultation up to signing the contract! I contacted Ecoline about getting a quote to replace my very old windows. Alexander Havkin set up an estimate consultation quickly. He came fully prepared for COVID - mask and everything - which was wonderful. He was very knowledgeable - he listened to what I was looking for in windows, walked me through the options, and explained pros and cons, warranties, installation procedures, etc. Very helpful - I'm a new home owner and have an older home. I was also sent an item-by-item quote, and given plenty of time to finish meeting other window companies (no pressure). Absolutely the best price - with referral bonuses to boot.

Your windows are your view to the world … and to the weather (more important). But they’re a big financial and installation decision. Take care how you decide, because there are many windows suppliers: some just sell other’s windows and tack on a profit for themselves, some make manufacture and sell their own. Having many suppliers (competition) allows you, the buyer, to compare price and quality. If you have science or technology expertise, you can delve deeper into the window superiority, and even the installation quality. The buyer should understand the window project: maybe you only need the glass replaced, not the entire window. Anyways, depending on how much work you need done, spend some time delving into the topic.I was planning the whole panorama, all 10 windows in my house (we’re talking big bucks). I did my homework and selected Ecoline Windows. Why? Several considerations: Their product is high quality. The salesman (Vlad B.) made several convincing presentations with models and was knowledgeable, devoted, trustworthy, and the price was competitive. I know this because I obtained 5 comparative quotes and conversed with these sales persons. I would not pleasantly discover until later that the installation team (Ivan & Vlad S.) was skilled, expeditious (2 days’ labour), clean, polite and generous (giving more than was expected from them). Finally, quality control (Polina) kept calling how the work was progressing; you can whisper problems (which for me failed to materialize) to her in case you have somehow gotten yourself in a tizzy.I recommend and endorse Ecoline for these reasons. There’s much helpful information and awards on their website. Be cool and warm behind your new home windows.

Very happy with the install, the communication, and the salesman that came to my house. No pressure, no BS, and no drama! The install guys were friendly, informative and showed great attention to detail. They had a tough time working around stucco that was improperly installed around my windows but finished it off nicely. The price was great compared to the so called “Baumler approved” company and I think I made the right decision with Ecoline! I highly recommend them and their product. When I am ready to do the next couple windows, I will be calling Ecoline!

Dave Ott

02:39 03 Oct 20

Our windows were installed quickly and professionally by Mike & Derek of EcoLine windows. They were polite, friendly and did a great job cleaning up after the install. The new windows are a significant improvement on our old windows, slide easily and without issue and will be much easier to clean.Due to the pandemic, there was a delay having the product manufactured and installed during which there was little communication and I had to follow-up a few times, but very satisfied with the final product and install results. Our install team did noticed and let us know about a snag in one of the new screens and looked after reporting this up to EcoLine for us. Although we are still waiting for the screen repair / replacement, EcoLine did call today to book the appointment to finish the repair next Friday.

I want to share my experience regarding Ecoline Windows. When I requested a quote, they sent me a person with high knowledge and ease of conversation, the service was good at that time and I hired this company to change 17 windows and two patio doors. The price they gave me was excellent with ease of financing, the installation began two days ago by the LEO'S Team, really this team of people was excellent, they always followed the COVID protocols, they never put my family or them at risk. Kindness, friendliness, and a high degree of cleanliness, great standards of professionalism were what they gave us.But what has surprised me the most in a good way is the follow-up from the first day to the last by the Quality team guided by Mrs. Polina Levitova, it has been impressive as is the final product, beautiful windows, and high doors quality, with a great installation.I can say that I am very happy as well as my family for having chosen this company to do such a great job as it was all the windows and doors of our house. In these times it is difficult to see companies as responsible as Ecoline Windows.

We have been Ecoline customers since 2014. They have been back to do warranty work on our windows a few times since they were installed. The most recent visit was last week.We have nothing to complain about. The purchasing process was exactly what they promised. The installation was exactly what they promised. The warranty work they have done shows that they stand behind their product.Without exaggeration, the new windows have had a noticeable impact on our lives. Our house is warmer in the winter and cooler in the summer. We don't have to deal with fog when it's cold and we can open the windows to cool things off when it is hot.Ecoline was not our cheapest quote at the time. But they seemed to have the best reviews, so we went with them over their competitors. It was an expensive purchase, but it was one we do not regret.

In the service industry, the best customers are those who buy without haggling, pay on time and don't complain. Everybody in the service industry wants customers like this. Everybody loves them.The worst customers are those who buy a discount service and then complain that they didn't get premium service at the discount price. The most despicable of these customers are those who who take it one step further and give you a one-star rating -- for giving them exactly what they paid for.Frankly, if I had somebody working for me that behaved this way, I would get rid of them.----------We have been Ecoline customers since 2014.

He made my decision easier.The installation was quick and the installer cleans up inside and outside of the house. The windows looks great and I have no complaints at all.If you are looking to replace your windows..I do recommend Ecoline!

I’m in process of getting my second window from Ecoline. The first window we got is doing great, we really like it, and they did a great job with keeping everything clean. We’re expecting the same great service with our next window and the other windows we will be getting down the road. Alexander is great to work with. He gives great advice and listens to what we want. He also loves dogs, even if they’re big and slobbery!

Ecoline has always been top tier very professionally done windows for homes and we will continue to use Eco line in the future.

Had a wonderful experience with Joel from estimate to signing. We felt very educated about what we were getting and comfortable signing the final contract.

Financing options were very easy to understand and made getting the whole house done at once feasible.We can't wait to schedule our installation!Thank you Joel and Ecoline

Ecoline has great pricing with great products, I got 4 different quotes but they stand above and beyond the other companies. Trust and price are the number one issue when it comes to choosing the right one. With Alex being very detailed, knowledgeable, and patient (answered every questions logically), I feel like we've made a right decision. He even give us an assurance he’ll send the best guy for the job. Excited to see the end result!

We are so pleased with our new windows. We haven't stopped smiling since the windows have been installed. We had 2 doors, 15 windows and 1 patio door replaced. The installers arrived on time and worked quickly and neatly. They were also respectful and spoke at normal levels. We chose this company because they were able to replace the basement windows completely instead of only doing a retro fit and they also have a computer program to let you see what your house will look like before you start. It helped us decide to chose a different door then what we had originally picked. The sales manager was pleasant and knowledgeable. I can't wait to see how our energy bill decreases in the winter. We are not disappointed that we chose this company

What are End-Vent Sliding Windows?

When looking at new sliding windows, customers often come across end-vent sliders. The sashes in these units can be unlatched to turn at a 90-degree angle to the frame, much like the sash in casement windows.

Although this feature looks very modern especially in a double slider, homeowners often misunderstand its true purpose. While these windows can give you a beautiful unobstructed view, the turn-in in function is intended as a maintenance feature. It allows for cleaning of the outer side of the window from the inside of the house.

You shouldn’t keep the sash in a turned-in position as the weight of the sash can cause stress on the frame resulting in deformation or even breakage. This is especially crucial in triple pane slider windows because their sashes are much heavier.

How Much Do Sliding Windows Cost in Calgary?

In 2024, a medium-sized single-tilt sliding window with triple-pane glass and standard white finish costs approximately $1,400.

However, prices vary based on several factors. For a more precise estimate, use our replacement windows cost estimator or contact us for a free quote.

Top factors affecting sliding window prices:

• Size and dimensions
• Type of glass (double or triple-pane)
• Frame materials and finishes
• Energy efficiency features (Low-E coatings, gas fills)
• Installation complexity

How to Choose The Best Sliding Windows in 2024

Regardless of the window style or type, all windows you consider should be ENERGY STAR rated. ENERGY STAR is an international organisation that classifies and rates energy efficient products, from household appliances to building materials.

As of January 2020, homeowners no longer have to consider a Climate zone when shopping for windows that are ENERGY STAR® certified in a particular area. A product in Canada is either ENERGY STAR® certified or not, with a single standard applied nationwide.

But keep in mind that if you want to purchase new energy-efficient windows in Calgary, you should only consider models with a minimum ER (energy rating) of 34 to ensure that these windows meet the Canadian government fenestration standards.

ER Ratings are a value given to windows, based on a calculation of different performance factors. These include the U-Factor and Solar Heat Gains. The ER rating has been devised specifically to make it easier for consumers to understand and compare window performance from different manufacturers.

• U-Factor is a calculation of how conductive a window is, how it is affected by convection heat loss and the emissivity of the glass in the panes. At the very basic level, the lower the U-factor, the better your window is at keeping heat inside the home.
• SHGC: The Solar Heat Gain Coefficient measures how much heat from the sun a window gains. Although ideally, you want as much heat from the sun in the winter months, most modern windows with high SHGC end up overheating the home. High SHGC factors are great for windows that see very little direct sunlight and can maximize energy gains in those places. The lower SHGC, the less heat from the sun your windows let through.

Casement & Awning $1,327-$1,400

Hung $968 – $1,350

Bay & Bow $1,374 – $3,500

Fixed Picture $800 – $1,613

Hopper $900 – $1,400

Custom Shape $1,504 – $2,755

ER Ratings or U-Factor: what’s better when comparing windows?

You can often see window ratings represented in either one of these values. But which one is a better representation of a window’s performance?

An ER number is a more encompassing measure of how a window “transfers” energy. The more heat it gains rather than loses, the more efficient a window is considered. Therefore it always important to look at the SHGC number to see how it plays into the window rating.

By providing your phone number and email, you consent to receive calls, texts, and emails regarding your request, including follow-ups and updates. Text HELP for help or STOP to cancel. Message and data rates may apply. Message frequency varies.

+1 (866) 644 6418

The U-Factor on the other hand assesses a window’s resistance to heat loss. This is especially important to consider in Canada as we often have longer nights in the winter where it is essential for a home to retain as much of its heat as possible, while not gaining any energy for the sun.

• A high ER number may just mean a window gains a lot of energy from the sun. A low U-factor will mean that a window is great at keeping the warm air in.

When comparing performance ratings from top Calgary window companies, you can use Natural Resources Canada website to analyse a full list of Energy Star approved companies and all their windows and doors energy ratings to understand whether their products match your expectations in terms of energy-efficiency for your house.

You will probably notice right away, that a couple of companies don’t have information available for their slider windows. This information is not listed under the company’s registry on the NRCan website. This could mean one of two things: either slider windows from that company are not Energy Star rated, or the company gets their slider windows from elsewhere.

If you are considering slider windows for your replacement project, make sure that the ones you get have the energy rating of at least 34 since this is the bare minimum for windows to be considered energy-efficient today and qualify for the government rebates in Canada.
