    If you really want to get the perfect custom windows for your home, you should know that there are factors to consider beyond the quality of the product.

    As you guessed, we’re talking about window installation. A poor installation can do more harm than good and essentially nullify your investment in the performance and efficiency of modern windows and doors.
    Yet plenty of companies on the market fall short on quality workmanship, even if their products are superior to competitors’.

    Although it is difficult to evaluate the skills or work ethic of any window and door installers until the day of the installation, knowing what to look for can help ensure your new units will perform at their maximum, saving you time, money and nerves.

    Expertise & Certifications

    It goes without saying, your installers must know what they’re doing. Although the trade is not officially regulated, there are still certain work certifications installers can possess.

    • WindowWise is a program that offers training and evaluation for installers in Canada. Ecoline Windows and Stage (our manufacturer) have this certification, ensuring the best quality when it comes to any window and door installation.
    • The CSA also outlines a standard to which all installations should be performed, although may not necessarily be perfect for every installation.

    When seeking the assurance of certified installation for your windows, the most effective strategy is to partner with a reputable window company that offers a “supply-and-install” type of service. Such companies typically employ trained in-house installers, ensuring a team of professionals capable of handling projects of various complexities.

    This approach guarantees that your local window installers meet the highest standards of quality and expertise, which is especially vital when you renovate basement windows and need your egress window installers to know all the ins and outs of your local building codes.

    Transparent Communication

    A good way the installer’s knowledge will naturally be tested is in how they communicate with you. Installers that know what they’re doing, should be able to explain the reasoning behind their methods, and why their process is preferable to other options.

    And, of course, a big part of the impression a company leaves, is in how their employees communicate with their clients.

    • Are the installers willing to listen and respond to your concerns?
    • Are they personable and polite?
    • Do they explain why they’re doing something or merely argue that it’s the right way?

    All these things make the best window installers and are a good indicator of how much attention to the quality they have.

    Quality Control

    Not all knowledgeable installers are quality. And all quality installers understand the importance of a proper installation to the performance and longevity of your windows. Only through a high attention to detail can an installer turn a good installation into a great one. Especially when it comes to complex projects such as bay & bow windows installation, picture, awning or custom-shape window replacement.

    • Are your window installers ensuring all windows are level and square?
    • Are they checking for damages before installing the product?
    • Are they caulking the outside of the window completely and accurately?
    • Are they ensuring the surrounding wall or finishing isn’t damaged during window replacement?

    These little things are up to the installer to notice, and really separate the best replacement window installers from the rest. Another promising approach would be to look for different ratings online that summarise the top installers in your region.

    For example, you can search for the “best window installers in Calgary” and check various articles by independent platforms that share all the pros and cons and real-customer reviews for any window company you are interested in. In this way, you can see the bigger picture and check the reviews online about what their past clients say about the quality of window installation, communication, and any potential pitfalls. The same can be done with window installers in Edmonton, Ottawa or any region you want to review.


    Although overall cleanliness may not affect the result of your installation or the performance of your replacement windows, it is usually a sign of a knowledgeable quality installer. A lot of companies are starting to catch on the importance of leaving a site clean.

    Some window installers even offer options to seal off entire rooms for a replacement. But at the very basic level you want someone who tries to make as little mess as possible, and makes sure to clean up after they’re done. This demonstrates integrity and pride in an installer’s work.

    There are many window installers to choose from. Remember that a good installation can help you maximise the performance of any windows. A bad one, on the other hand, can ruin any benefits of efficiency that the product has to offer.


    Who are the best window installers?

    The best window installers are those with a proven track record of quality, reliability, and customer satisfaction. Look for companies with certifications, positive reviews, and a commitment to using high-quality materials and the latest installation techniques.

    How do I choose basement window installers?

    When selecting basement window installers, prioritise those with specific experience in basement and egress projects. They should offer solutions tailored to the unique challenges of basement windows, such as moisture resistance and security, and comply with local building codes for safety and efficiency.
