St. Clair Windows replaced patio doors and windows for us. Their crew was professional and fast. They were awesome and cleaned up after the job was done. We will go back to them when we get other windows replaced. I would definitely recommend them to anyone.

Professional from start until finish. Completed the work in the given time frame and were super friendly. They left the area of the home they worked in spotless both inside and out. Highly recommend ! Plus the new window looks great !

We had a great experience when we we replaced every window and our front door. The team was very efficient, finishing over 15 windows in two and a half days. They do an amazing clean up as well after themselves. Our door was a custom colour and turned out fantastic, with a new storm door. The guys are super nice, knowledgeable and I would recommend them to anyone! I love my brand new door especially :)
