Our Step by Step Process

Step 1: Free Consultation & Measurement

Our Reliant Windows & Doors rep will advice regarding which window types will be best for your home and family. For example, if you have young children, you will not want to install windows that are too easy for them to open and fall out of. If you live in an area that experiences a lot of rain and snowfall, they may recommend awning windows that will still allow airflow during inclement weather.

After picking the types of windows you want, our Reliant Windows & Doors will take down the measurements as well.

Step 2: Installation Assessment

Our Reliant Windows & Doors rep will also assess the exterior environment and determine the rain exposure conditions and the performance grade for the new windows and doors. The environment inside the home is also assessed. The home will be inspected for water penetration and other performance issues. Replacement product options and the installation methods are discussed.

The installation method must be appropriate for the home’s rain exposure conditions. Once the assessment is completed, you will receive a complimentary and detail quote from our office.

Step 3: Preparation

Once the quote is accepted, our Reliant Windows & Doors installation team will schedule a date and time to remove and install the new windows. Before the installation team's arrival, please remove any window coverings and furniture so that the installation team has plenty of room to work.

Step 4: Removal & Installation

Our Reliant Windows & Doors installation team will arrive on time with the products that you've ordered. We will then remove the old window and insert the new one. If you have time on the day, feel free to stick around and watch our installation team does their magic.

Step 5: Project Walkthrough

Once the installation is completed, our installation team will conduct a walkthrough with you to make sure you ae happy with the work done!

  • Sonya Traynor
    I had my windows installed by this Kitchener window company and I couldn't be more happy with the whole process. From my estimate, measurements, showing me full samples of what my basement and main floor windows would look like, and the price of it all in one consultation. The installation by two gentlemen who were able to get all 8 main floor single slider windows and one sliding glass door put in within 7 hours. They kept all the areas clean and were easy to work with. I appreciated that I wasn't bombarded with emails and phone calls concerning if and when I was going to proceed with the purchase while I got other quotes. I'm very happy with my decision to go with Reliant Windows! null

    We are quite satisfied with this company in replacing our 13 windows and a fiberglass door. Not only did we get a good deal with the rep. James, but we could even have them installed separately according to our financial situation, which made our life so easy. Also, the installation team, Shane and Konstantin did a great job, very professional. Thank you guys! We would highly recommend this Burlington windows & doors company! Good job everyone at Reliant Windows! null
