"Paul and his team were great. We replaced most of our windows as well as an old wooden window. We were concerned that the replacement for the wooden window wouldn’t come out as nicely but the replacement was beautiful! We are looking forward to our electric bill this summer."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."
