When choosing a window company in Calgary there are several things you need to take into consideration. Obviously the quality of the product and installation has to be up to a certain standard.

But what about things like customer service, and an overall pleasant experience?

While you can’t always figure out how good the windows are until they are installed, there is plenty of information you can find about a client’s experience, by doing some basic research.

There is also often some debate as to whether you should go with a smaller family owned company or a big box store. Smaller companies have the opportunity to work closer with the customer and provide an exceptional service while with a bigger retailer or window dealer you often get the advantage of a product sourced from multiple suppliers.

Today we will look at two Calgary window companies that fit each of these criteria – Cossins Windows and Greg Martineau (now part of Centra Windows)

Cossins Windows Calgary

  • Homestars: 8.6
  • BBB: Accredited

About
Cossins is the family-owned and operated company since their beginning in 1978, offering window services in Calgary. An advantage for customers is that the company manufactures their own windows locally and specializes only in residential window solutions. The company also has a local showroom, which you can visit to see all their products.

Product
Cossins carries all regular window material choices such as vinyl, as well as aluminum clad, and traditional all wood windows. They also make patio and entry doors. The company website features Energy Star information on all the windows they manufacture for easier comparison. A plus to this company’s product range is that they manufacture and install skylights, which few Canadian window replacement companies specialise in.

Certifications

  • ENERGY STAR rated

Warrranty
Cossins’ website elaborates on their window and doors warranties in Calgary pretty well. The company briefly breaks down their service procedures and offers an online submission form for a service request. They offer a 20-year warranty on the product and 10 years on labour. The warranty is transferable with the original purchaser’s receipt, being a typical offer on the window market.

The company has decent homeowner reviews on HomeStars and is accredited by BBB, making it a good choice if you are looking for durable windows for Calgary’s climate.

Greg Martineau Projects Calgary (now part of Centra Windows)

  • Homestars: 9.2
  • BBB: A+ (accredited since 1995)

About
Greg Martineau has been on the Calgary market since 1995. The company became a part of Centra Windows in 2023 and continue serving as one of the most well-known local window manufacturers and installers in Calgary.

Product
The company offers not only vinyl windows but also traditional wood or aluminum clad windows, having a wide range os residential window styles available. The company deals in both residential and commercial window and door replacement, sitting among the preferred window brands for Calgary homes. It is worth a mention that the company also specialises in siding work which is important because siding often gets damaged during the window installation. Another service that Greg Martineau offers that sets them apart, is their so-called “tune-up” service. Essentially the offer is to come out and give the customer a quote on all the windows, but only replace the ones that are the least energy efficient.

Certifications

  • Energy Star rated and CSA certified
  • Member, Calgary Homebuilders Association
  • Member, Renomark Program

Warranty
Being a part of Centra Windows, Greg Martineau should offer the same 25-year warranty on their windows and doors. But make sure to clarify this with the company representative if you are considering them for your replacement project.

Overall, Greg Martineau Projects has a positive presence online with many customers speaking volumes regarding their innovative window technologies and installation. The general negative feedback from the customers was regarding the subcontractors that a company dealt with throughout the different stages in the job, however this should not be an issue now when the company is the part of the Centra Windows with their many in-house installers.

Conclusion

When making a quality comparison: Cossins Windows and Greg Martineau Projects, it is worth noting that either of these companies is suitable depending on what your window replacement requires. If you only need vinyl windows and are looking to install them as fast as possible, Cossins may be a better option as they manufacture locally. They are also one of the few companies that work with skylights. It is hard to judge their customer service, as the company has a smaller presence online, with very few reviews that aren’t testimonials curated on their website.

If you want to get more fancy with your replacement and get wooden windows for example or aluminum-clad ones, you may want to consider Greg Martineau.

In either case, be sure to specify the company’s warranty terms and the specific window style you look for. Both of these companies can be considered if you are looking for a quote. Though they both specialise in very similar things, each of these companies would be good for very different customers.

F.A.Q.

Window replacement is a significant investment, no matter which company you choose to order windows from. However, choosing a local company such as Ecoline, Cossins, or Greg Martineau may get you a more reasonable quote compared to global brands.

Both window companies offer energy-efficient products and have Energy Star certifications. Check the precise energy ratings of the specific window models you look for to determine the company, which offers a better solution.

Yes, the company joined Centra in 2023 and now operates under its management.
