Reliant Windows & Doors FAQ's

Why are the windows called 'Awning Windows' ?

Once opened, an Awning Window looks like the roof like shelter of canvas or other material extending over a doorway, from the top of a window, over a deck, etc., in order to offer protection against the sun or elements.

How do they work?

Are they more affordable or more costly than other windows? How so?

Each window project differs. It is difficult to provide an accurate cost range for a home which can vary considerably in the number and size of its windows. Costs also depend on the frame glass and material options. Double and triple-glazed windows or those filled with argon gas, increase energy savings but add to first upfront costs. You could be pleasantly surprised by how many windows could be more affordable than others.

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 has a lot of rain and snowfall, we may recommend awning windows that will still allow airflow during inclement weather. After picking the types of windows you want, our rep will take down the measurements as well.

Step 2: Installation Assessment
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!

What People Say About Our
Bay Windows Services

  • Gavin Gunn
    I don't usually give reviews but when a company does such a great job it has to be noted. Its A+ all the way for Reliant Windows! From the estimate to the installation this Kitchener window company was great. I had quite a few windows installed including bow and bay windows! I had several other companies give estimates and none of them even came close to competing with them, on price or customer service. I strongly suggest not wasting time on shopping around for windows, just call Reliant Windows! null

    I contacted Reliant Windows after a friend told me about them. They were able to come out and give me a quote within a few days and we got the bay windows ordered a few days after that. I replaced 2 windows and it took them right around 3 hours. They did a very good job cleaning up after themselves as well. They were professional and friendly from start to finish. I was able to get a better window for about the same price as other companies were charging for a lower quality window. If I ever need more windows replaced, I will absolutely call this Kitchener window company again! null

    I had basically all of my windows replaced (which totaled 19 windows) in my home by this Kitchener window installation company! The crew was very friendly and took care to protect our home while the windows were being installed. Everything was cleaned up afterwards before they left and there was very minimal that I had to do to put my house back in order. Overall I had a very good experience and would definitely recommend Reliant Windows. I am very satisfied with the quality of the double slider windows and end vent slider windows as well as the warranty that comes along with the purchase! Thank you!! null

    When we used Reliant Windows, everything through the process was easy. The employees were friendly and knowledgeable, the windows arrived in the appropriate time frame. Customer service was quick and efficient for any questions I had. The installers were so nice and voiced their opinion for the trim. They said it would look better with a thicker trim because of the ledge the garden window I ordered sat on. I agreed and they went right to work to finish up the installation properly. I am SO incredibly happy with all of it. I had been wanting to get new picture windows and bay windows for years! This Barrie window company is the best! null

    I replaced 15 Windows, 2 awning windows, 4 single slider windows, 1 bow window, 1 bay window, 2 custom shaped windows, and 5 picture windows, with Reliant Windows & Doors. Our salesman was a rep named James who was excellent. The window installers worked faster then I anticipated and cleaned up after themselves both days. Thanks for a great job, if you need replacement windows I highly recommend these guys. Ask for James... null

    Installed some bay windows in our living room as a father day's gift. These new windows totally give a whole new feel to the room. It’s so much better when you’re letting the light flow in. Thanks, Reliant Windows & Doors, the windows look amazing and wish I could install more. Would recommend to anyone, they got it done in one day and I swear I didn’t even notice that they’d left since they were so quiet and tidy. If you’re looking to do a home renovation, do it here. 5 stars! Great product and great service! null
