Supreme Windows

Matt was great to deal with from the beginning of our project through to completion.

Matt made himself available and was willing to answer any questions we had on our project. He was accommodative and brought out his installer twice given a revision we made to one of the window openings.

Very professional from the initial quote to installation. Matt was very good at managing expectations as window manufacturing has quite a lead time currently. This was key as the installation was part of a larger project and we could work around the timelines given.

We would highly recommend Supreme Windows.

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.

This was the only company willing to consider our small project, all others refused our inquiries. Matt the owner, responded quickly to my e-mail and came out within days to view our basement window replacement project. Along with the installer they answered our questions without hesitation as we had a rusting frames issues from 40yr old windows plus a previous foundation leak issue at one of the windows. The window was ordered, received and installed within the 6-8 week time frame and it was beautifully done. No mess, perfect fit and completed within a half day. Installer, Arthur, was on time and very personable. Matt is easy to work with, came out to view the job and always follows up promptly. Very impressed with Supreme Windows all around. I was lucky to find them and they did a great job at my house.

Needed to replace five 30-year old leaking basement windows. Used Supreme Windows web-site to request an estimate. George called us quickly, visited our home the next business day and gave us a written estimate, which we agreed to. Work started within 1 week and was completed in less than a day. We were very happy with the windows but wanted to modify the capping on two of the windows. George reviewed with us, agreed and sent a tradesman to make the changes. Overall, we were very happy with the product, and with George and his crew!

Delighted with the service the product and installation team! Very helpful in choosing windows and doors! Installation was amazing without any interruption!

We are truly enjoying our new windows thanks to all at supreme windows for your help!!

My extended family has used supreme windows for years and have been extremely satisfied. I contacted George to review my needs and we promptly arranged for a house visit and sizing. George patiently review with me the various window options ensuring I was happy with my selections. The windows arrived with a very minimal wait time and the installer team did a fabulous job. I love my new windows. The are much more energy efficient and the real surprise was how much quieter the house is now.

My main window had a small flaw in the glass and this was promptly addressed and repaired by the window manufacturer.

Required a backyard sliding door that required no window treatment. George recommended going with the backyard sliding door with mini blinds. Awesome suggestion and fabulous results! Extremely satisfied customer, thanks George!

We loved our windows installed by Supreme Windows in Mississauga. However during 10+ years the paint color on the windows has changed from the capping color, can actually be wiped off! From Sandalwood to PINK!!! Their window supplier will not even come to look at them...Please contact me to see how awful this is. I cannot tell you how hideous this looks. I never wanted PINK windows but I am stuck with them. Again windows are great but paint color has changed and looks absolutely terrible. Do not purchase from them! George from Supreme came to look at them and definitely saw the problem and took pictures of the windows and of the color that we wiped off on a cloth! He agrees there is an issue but says we need to contact the window supplier ourselves. He even alluded to the fact that he might not be able to use this supplier anymore!!! Would be interesting to know if he still is. These windows are out of warranty but this color change did not happen overnight....it has been going on and is now just SO noticeable...I've never seen any one else have windows that look like this. Perhaps if the capping had changed color as well it wouldn't be so noticeable! We went with a reputable company and have great windows but AWFUL color. Contact me!
Please contact me to come and see these awful PINK windows before you ever purchase from Supreme Windows. I have been patient and waited for someone to do something and they haven't so I'm posting this review....and looking for their signs to warn people. I don't want anyone else to have PINK windows 10+ years down the road!

The Rehau windows are pricey but are nonetheless worth every penny. Six years on, one of the kitchen windows had a leak in the thermal pane and this pane was replaced by George (the owner) quickly, efficiently and without hassle. Try and get that kind of service from another window installer six years after installation! I am very pleased with Supreme Windows and would recommend Rehau quality and Supreme Windows installation to anyone!

Working with George, the owner, has been a delight, so far everything is going to plan, we expect to have the windows installed by next week. He and his team have been extremely professional and accommodating.
