From start to finish, everyone I dealt with at Supreme Windows was courteous, knowledgeable and always making sure to stay in contact!! Jim and Dave in the office were amazing and always returned calls or emails. The crew that came for install, just this past week, were super friendly, efficient and had impeccable workmanship!!
You can tell that everyone cares about each client and the products and services they are delivering!!

From our sales representative, Karl, to the installation team, all was very exceptional. We have used Supreme Windows for many years and have always had wonderful service. Retro fitting windows and doors is a challenge that Supreme Windows rises to each and every time.

Supreme quoted my windows in Dec and delivered 4 weeks ahead of schedule...well done guys

We had a front door replaced including the frame. They made a point of fast tracking it because our current door and frame was damaged. Within weeks they had done the quote in person, removed our door and put a new one in place.

Their customer service is first rate and the costs for their services reasonable.

We are now getting some of our windows replaced and upgraded.

We replaced our front door and 10 windows last August, and the final 16 windows this month. The people at Supreme Windows, including the installers (Dimitri, Crystal and crew) have been excellent - incredible attention to detail. We are very happy with our new windows.

Jim was an excellent salesman, coming by the house multiple times to offer options and advice and to guide me on timing in conjunction with other contractors. Steve and Scott and crew were just the best installers. Clean, thorough craftsmanship, friendly and hard-working guys. Made friends with my dog too!

Replaced 30 year old windows with triple pane glass. Very happy with finished product. Our sales rep Les was very helpful in our selection. The installers were pleasant and efficient and did a great job of cleaning when they were done.

Highly recommended.

I have dealt with Karl since 2017 on various projects. He has been with Supreme Windows for 25 years. Having also installed windows and doors in the past Karl has a vast knowledge of the whole process not just the sales end. All this helps one make an informed decision on the best way to procced with one's renovations. Also the service department experience has been excellent. I have found their pricing inline with the competition. On your next renovation project I would definitely give Karl a call.

I had Supreme redo all the windows in my parents' townhouse. The salesperson (Ed) was really informative about the product, options and the installation process. The windows were actually ready for installation about a month before promised which was great. The installation team (Jody, Dave and Gord) showed up exactly as arranged, were extremely professional and informative every step along the way, and left everything neat and tidy. Windows look great. Couldn't be happier!

A friend of ours had new windows installed in his condo. When we saw them and couldn't believe how great they looked, we went home and contacted Supreme for a quote on our sons house.
Due to Covid, the manufacturing and installation took about 5 months and I want you to know that the windows are worth the wait!
Our son has noticed the warmth in the house already and the windows look beautiful.
From the start of this adventure, everyone we dealt with at Supreme were very professional. I would recommend them to everyone who asks.
Thank you to everyone at Supreme who was involved!
