What Our Customers Are Saying

Don’t just take it from us, let our customers do the talking!

We had Window Bay install windows and doors in our home in Brampton in 2008. Early January 2016 we saw window glass sweating between 2 panes and called this company for repairs, because our windows were warranted life time. We got a same day response – a technician came by, measured the glass and within one week the new glass was installed.
The job was done free of charge, we didn’t even pay for the visit and the labor to install.
Thank you Window Bay!


We went to the window bay to get a price for our windows and Konstantin came to confirm our measurements. Although our house is fairly new – 8 years old, the vinyl windows from the builder didn’t close properly,some of them didn’t even open, because the hardware broke down or stuck. Konstantin checked our windows and confirmed our online price. It ended up being much less than what we got from other companies – fitted in our budget right on time!Windows were ordered in November and installed in January. We never thought it would be possible to do our windows in winter, however the installers crew was efficient and quick like it was in summer time. They took out old windows one at a time and replaced it with a new one – this way our house wasn’t exposed to a heat loss. The performance of new windows was great! We never expected our new windows’ insulation will work so good!
I would like to personally thank Konstantin for taking care of our order.

Despite of the best price among others, they provide very high quality products. Plus, they also spent only 2 days on installing my 20 windows (including 1 bay, 1 huge picture window and 1 arch windows) changed and the front glass door. I am very satisfied with their work and they are very honest, responsible and friendly people. Highly recommand to anybody who is looking for a window and door replacement.
