About Us
Supplying, installing, and servicing windows and doors for builders, contractors, architects, and designers across the Greater Toronto Area and Muskoka.
Grace Windows & Doors has worked alongside the construction trade since 1994. Across our team, that’s more than 50 years of combined experience specifying, installing, and servicing windows and doors — experience we put to work on your job site, not just in a showroom.
We’re not a big-box retailer. We’re a small, hands-on supplier that builders, GCs, architects, and designers come back to project after project because we show up, we know the product, and we stand behind it after handover.

Our Suppliers
We are an authorized dealer for two manufacturers, which lets us match the right product to your project's performance requirements, and architectural style.
Our Reviews
Real homeowner reviews reflecting trust, care, and quality from Grace Windows and Doors.
We purchased a very large triple slider (703kg) from Dillon at Grace Windows. They are the representatives for Reynaers. We had a couple of issues with the installation (normal new construction stuff) however, whenever there was a problem, Dillon was on it and had the installation team out to our home promptly to sort out this issue. Thank you, Dillon!

We recently replaced three large bay windows in our old Toronto home. Throughout the process, our interactions with Jeff were outstanding. He was professional, attentive, knowledgeable and more responsive than any contractor/tradesperson I've ever worked with. Even when we had some hiccups due to our house being so old, Jeff, Dillon and the Grace team ensured that issues were resolved quickly and that we were totally satisfied. Highly recommend for sure!!! :-)

Customer experience and support is essential when replacing windows and doors and Grace Windows and Doors is truly exceptional. We use Grace for all of our new custom home builds and no longer seek competing quotes as Grace carries the top window manufacturers and quality, price and after sale service simply cannot be beat. This is a family owned business that takes great pride in their work and we highly recommend them. Palmarius Homes

Grace Windows and Doors has been a pleasure to deal with from start to finish for our custom home. They have excellent quality, current products, combined with efficient installers, and knowledgeable staff. Even after the install, Steve was responsive, honest, and ensured that we were satisfied; we could not be happier with the finished result. Thank you!
