We had new windows installed in June 2022 for almost the entire house.Matt and the team were great – the installation was really quick, efficient and high quality. Matt was very responsive to queries and kept us updated on lead times and installation dates.Overall, very pleased with the service and our new windows!

We had the pleasure of dealing with Matt! Overall we had a great experience from start to finish. We replaced all the windows and doors in the house. From start to finish Matt was very involved and had lots of follow up to make sure I was comfortable. Even during the install he came to oversee both days. The installers were super quick and cleaned up after themselves. Definitely recommend Matt and team!

Matt the owner was very professional throughout quote – installation process. He even assisted me with the re-installation of our California shutters after the window work was complete, which was a big help. The installers were also excellent – VERY hardworking, professional and had been working with Supreme for many years. Would highly recommend this company.

We are very happy with everything that was done, The door itself is quality, and the installation team were very experienced ,prompt and courteous. They cleaned up very well when they were done. We ordered 3 more new windows again, I wouldn’t hesitate to recommend Supreme windows.

Amazing and professional service! Matt and his team were a pleasure to work with and they did an excellent job installing our window! It looks a lot better than what we had before. The price we got was very reasonable and within our budget! 10/10 would recommend! :)


Very efficient and professional, our doors look beautiful. Would recommend to anyone!


I must say the service was excellent. The workmen ensured the area was cleaned after the installation was completed. I am very impressed with the quality and design of my door. I recommend Supreme windows for everyone’s doors and windows need. I’m so happy tears came to my eyes. Continue the great service.

Have to tell you how pleased we are with the windows. Your team is so hard working. We were amazed that they got all the windows in place yesterday.


We are very happy with the windows installed yesterday – they are just perfect for this lovely home.  Thanks for your great service – always communicating promptly.  We appreciate the Supreme Windows service.  Will certainly recommend and use your company again. Thanks for the nice photo.


Want to thank you and your crew for such a terrific job installing the windows. They look terrific.

We will recommend you to our friends and family and if we ever need windows again we’ll be coming back.

Enjoy your weekend.


Just want to say I LOVE THE FRONT DOOR! Todd was really surprised and loves it too.  We’ve received a lot of compliments on it.
I would like to replace another door – this is an exterior door from the laundry room.


We are very happy with the window & door.  The products are superb & the installers were very professional.

We will definitely recommend you to our family & friends.


Just wanted to say thanks again for the brilliant idea to install one large window in our family room. I sit here looking out at the trees, and watching the snow falls. It is just a wonderful addition to our room so thanks again

And all the best in the new year

I just wanted to take this opportunity to thank your company on a job very well done. My wife and I couldn’t be happier with our new windows. The installer was fast and extremely professional. Our home was left so clean that it was as if he was never there. We will be recommending your company to our friends and neighbours. Again, thanks so much.

Thank you.  We are very pleased with everything.

I will definitely send referrals your way.

Take care,


Have made windows in the master bedroom replaced about 10 years ago and the rest of the house windows last year. The installer were friendly and professional. Installation was done in two days and the guys removed all the refuse and left the place clean.
