Custom Window Designs

Great customer service, quick response and installation. Any and all questions and concerns were answered to make us, as newbies, feel better. John Moran and the girls in the office, along with the installation crew were all amazing! Love our new eves and soffits! Would highly recommend Custom Aluminum Windows & Siding.

Amazing windows if your looking to renovate your house. These guys are very professional and Finish work like promised on time with full installation and clean up. They are definitely the best window company in Mississauga

I cannot say enough about Custom Windows and Doors!

The windows fit perfectly, and they built and installed a unique window/door combo that is the nighbourhood hit!The company was within budget and delivered on time. I went back to buy a front entry door because I was very happy with their work.I highly recommend Peter and Custom windows and doors.

Highly recommend this company for their post-sales support. They went out of their way to provide free maintenance and support for their window screens, years after they were installed!

Absolutely great experience with Custom Window Designs!We decided it was time to change our front door, and got in touch with Peter (the owner) and he immediately gave us a brochure to hand select the EXACT door frame and design as well as window shades. So many designs it was hard to pick just one:) Shortly after our order was placed Branislav (window installer) came over and took exact measurements.Not long after we had the PERFECT door and window frames arrive and installed!!! BIG THANK YOU to Peter, Branislav, Sasha and the ENTIRE Custom Window Designs TEAM!!!I would absolutely recommend Custom Window Designs to anyone looking to do some upgrades to their home. Wonderful company, very professional, precise and prideful in the work they do, they truly care.P.S. We are so happy with our front door, we just placed an order for a second door. A garage door entrance into the house. That should tell you everything about Custom Windows Designs! :)Thank you everyone at Custom Window Designs!

Thank you Peter and crew at custom window designs. They were very fair and easy to work with. I love the windows, back yard, front and garage door you installed for me. Thank you for helping me get another new home build completed. Only company I would use in the GTA.

We got 3 doors installed on 2 separate occasions and the entire team at custom window designs are amazing. From the initial inquiry with Michelle, measurements with vlaz, all the way through to their amazing installers, every member of the team made the process seamless. A big shout out to their installers who are always on time, very careful and aware of their surroundings, and does an amazing job with clean up. We will 100% reach out again whenever we need new windows. Thank you!

Amazing windows and door for an unbeatable price. Peter and vlaz were very helpful and worked very hard with us to insure we got our windows and doors on time and on budget. Would highly recommend Custom Window Design to friends and family.

Ordered their custom installation for sliding doors and garage door. Works great so far. Thanks.
