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?

Awning Windows Hinged at the top and opening outward using a durable handle, they are often placed above or below other windows, or above doors. Awning is used on its own as a complement to casement or graphic windows.

How/why are they better than other types of windows?

Energy Advantage Low-E glass, Sealed units made out of conventional S class super spacer, fusion welded sashes and frames, interior contoured gas stops, exterior beveled framework, durable standard in-wall locking hardware, nesting hardware, and triple weather-stripping.

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.

Are they better for different climates?

Use the sun's natural heating and cooling skills to go green and lower your energy bills. We offer several unique glass coating types which help to keep your home warm in winter and cooler in the summertime. These special coatings reflect heat back to its source, whether it be the furnace or sun. Additionally, they're near-invisible--letting in maximum light while conserving the most energy.


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!

    Reliant Windows did an amazing job installing my new custom shaped windows! They finished the job when they said they would, and charged me what they said they would. Great product, great customer service, and a fair price. What more could I ask for from a North York window company?

    Absolutely pleased with these custom shaped windows. I can now use my front room in the winter! In the past I had to close this room off due to the cold. The look on the exterior is beautiful and I couldn't be happier. The crew at Reliant that installed the windows were professional and friendly. I will be using this Markham window company again!

    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

  • Madeline G.
    This Burlington window company is the best in terms of customer service. I had all of my windows replaced in November, and I must say that it all went very nice and smooth. Alex D was my sales rep and I would highly recommend him to anyone. He was very polite, came back 3 times to my house. Also, he was here on the day of the installation. Their custom shaped and awning windows look great on my home and I have no regrets. I compared their price to Pella and Brown and they were less costly, for the same quality window. null

  • Sarah M.
    As a builder, I needed windows and doors installed for my new project. After being constantly disappointed with other companies I had previously hired, working with Reliant Windows and Doors has been a blessing. Paul is one of the most knowledgeable and enthusiastic salesmen I know. Installers (Anton and crew) was very detail-oriented, and work fast. Everything was pristine from the very beginning of our collaboration, and I would gladly recommend them to anyone. Another project finished today (Feb 8, 2020) with the same crew - 1 bow window, 9 awning windows, 9 casement windows, and a custom shaped window! Amazing job and windows itself is really new generation product. I highly recommend this Burlington window company to everyone. null
