    One question that inevitably comes up when homeowners are shopping for replacement windows and doors is, who is going to install the product once it is ready. With a bit of knowledge and practice, it is definitely possible to replace the windows yourself and save some money on the total.

    But while chasing the perfect deal, many people tend to forget the real reason they are getting new windows – the long-term cost savings that come with the right installation of new windows. And that’s only possible when you choose professional window installers that provide impeccable measurements, seamless fit and maximum energy-efficiency for your new windows or doors.

    DIY Window and Door Installation: What to Expect

    For those with a knack for home improvement DIY, installing new windows or doors on your own may seem appealing. After all, who wouldn’t want to save on labour costs and enjoy the satisfaction of a job well done?

    However, DIY window replacement comes with its own challenges, and it’s important to know what you’re getting into before picking up a pry bar.

    Pros of DIY Installation:

    • Cost savings: No need to pay for professional labour.
    • Work at your own pace: Flexibility to do the project on your schedule.
    • Learning opportunity: Gain valuable home improvement skills.

    Cons of DIY Installation:

    • Requires precision: Incorrect measurements can lead to drafts, leaks, poor energy-efficiency and misfits.
    • Time-consuming: DIY installations can take much longer than professional jobs.
    • Risk of costly mistakes: Errors may void product warranties or result in expensive fixes.

    Professional Window and Door Installation: Is It Worth the Investment?

    For many Canadian homeowners, hiring a window or door installation professional offers peace of mind that simply can’t be matched by a DIY window installation project. While it comes at a higher upfront cost, the benefits often outweigh the expense, especially regarding quality, energy efficiency, and avoiding common mistakes.

    Pros of Professional Installation:

    • Expertise: Professional installers have years of experience and are well-versed in everything from how to install windows and doors to ensuring a perfect fit. This knowledge ensures your home stays energy-efficient, secure, and visually appealing.
    • Guaranteed Results: Reliable companies provide comprehensive window warranties for their labour, giving you extra protection if something goes wrong later. This can’t be guaranteed when you attempt to install windows yourself.
    • Time Efficiency: Professionals can complete a job in a fraction of the time it would take even a skilled DIYer. For those with busy schedules, this time savings is invaluable.
    • Energy Efficiency: Proper installation is crucial to maintaining your home’s insulation and energy efficiency. Even small gaps can lead to drafts, which professional installers are trained to prevent.

    Cons of Professional Installation:

    • Higher Cost: Labour costs add to the project’s price, and depending on the complexity, this could be a significant amount.
    • Scheduling: You’ll need to coordinate with the contractor’s availability, which can delay the project, especially during peak seasons.

    Hiring a professional also eliminates the need to gather window installation tools or risk voiding warranties due to mistakes. While DIY window replacement can seem appealing, a professional installation ensures long-term value and avoids common pitfalls.

    Supply-Only vs. Supply-and-Install Window Companies: What’s the Difference?

    Most window companies in Canada can be classified as supply-only or supply-and-install:

    • Supply-only companies are usually manufacturers or dealers working with window products. These companies may deal directly with customers or third party companies to install the product;
    • Supply and install companies either manufacture their own windows or have arrangements with window manufacturers for product supply.

    Although most supply and install windows and doors replacement companies often use their own dedicated installers, that doesn’t always guarantee the best job for the installation. After a bit of searching, you could find a skilled installer with good reviews.

    What makes going with a full-service approach company worth it is what happens after your windows have been put it in. Because the company assumes all the risks involved in all the steps of the project, it has your satisfaction as its best interest. That’s why these companies often have dedicated service departments that are committed to ensuring your post-installation concerns are addressed.

    Even the best third-party installers are often reluctant to return and service installations they have done when they are not committed to the company responsible for the installation.

    Window replacement warranty: what to look for?

    Long before even booking a contract, many worried customers ask whether the company offers post-installation service and maintenance. This means too many people in the past have been burned by bad practices. Because dedicated window suppliers offer service on their work, they are often able to offer better labour warranties as their future business depends entirely on your satisfaction as a client.

    A standard labour warranty is usually around five years. Take note that this usually doesn’t include caulking and window seals – those can be redone manually as often as needed to. Another question we wanted to bring to attention is that of “lifetime warranties.”

    While most salespeople are eager to throw the phrase out and offer it on just about anything, it is important to recognise that in construction terms “lifetime” refers to the lifetime of the sold products. Because it is considered appropriate to replace your windows every 25-30 years, the lifetime warranty for most window hardware is therefore 25 years.

    Step-by-Step DIY Window Installation in 2024

    For those still determined to tackle DIY window installation, a clear step-by-step plan is vital to ensure a successful replacement project. Whether doing this as a part of a larger home renovation DIY project or simply looking to replace a single window, following the right steps can save you time, money, and potential headaches.

    Here’s a practical, step-by-step guide to help you install windows yourself with confidence:

    Preparation

    Before diving in, make sure you have all the necessary window installation tools. These include a measuring tape, level, utility knife, caulking gun, shims, and a pry bar. Don’t forget safety gear like gloves and protective eyewear. Accurate measurements are crucial—double-check your window’s dimensions to ensure a proper fit.

    DIY window installation for beginners: a step-by-step guide

    1. Remove the Old Window: Start by carefully removing any trim or moulding. Use your pry bar to lift the window out of the frame, being cautious not to damage the surrounding structure.
    2. Prepare the Opening: Once the old window is out, clean the area thoroughly, removing old caulk or debris. Make sure the opening is level and square, using shims if necessary to create an even surface.
    3. Install the New Window: Place the new window into the opening, ensuring it fits snugly. Check for alignment with a level and adjust with shims as needed. Once it’s properly positioned, secure it by screwing the window into the frame.
    4. Seal and Insulate: Apply caulk around the edges of the window to create a watertight seal. Expanding foam insulation between the window frame and the rough opening ensures no gaps.
    5. Finishing Touches: Replace the trim or add new moulding for a clean, finished look. Ensure all seals are tight, and the window opens and closes smoothly.

    Wrapping Up: DIY or Professional Window and Doors Installation?

    While DIY window installation might seem appealing to save money, it often leads to costly mistakes. But still, there’s a time and place for both DIY and professional window replacement, depending on your needs.

    • DIY Installation: Ideal for quick fixes or when you purchase standard windows from big-box stores. These windows are often easier to handle and install for basic repairs or renovations. DIY can be a good option if you’re looking for an affordable, short-term solution and don’t mind taking on the work. However, this approach might not offer the best energy efficiency or long-term durability.
    • Professional Installation: This approach is the way to go when you invest in custom windows from a supply and install company. These windows are built to last 30+ years, providing a perfect fit, maximum energy efficiency, and enhanced security. Professionals ensure that your windows are installed with precision, keeping your home comfortable and secure while saving on energy bills over time.

    In the long run, professional installation saves money by avoiding poor energy efficiency, security risks, and future repairs. Letting an expert handle your windows will ensure your home stays safe, comfortable, and energy-efficient.

    F.A.Q

    Can I install windows myself?

    Yes, you can, especially if you’re doing a small replacement and using standard windows from big-box stores. However, it requires careful measuring, proper tools, and patience. Mistakes can lead to poor energy efficiency and costly repairs, so assessing your skills first is important.

    Is it difficult to install doors yourself?

    Installing a door yourself can be challenging. Precision is key—if the door isn’t aligned perfectly, it can affect insulation, security, and ease of use. For best results, professional installation is often recommended.

    What’s better: DIY or professional window installation?

    DIY is great for small, simple fixes, while professional installation is better for long-term investments. Custom windows installed by pros offer better energy efficiency, security, and durability, often lasting 30+ years. It’s ideal for homeowners seeking a perfect fit and maximum savings on energy bills.
