Customer Testimonials

by Jack on Thermo-bilt
Installed 20 windows and 2 doors

My Experience was great! The professionalism amongst all members of the installation team was exceptional. Robert our salesman was very helpful as well. He guided us throughout the process, making the project (beginning to end) a breeze. Thanks again guys! - Jack

Window Installation

They did 5 windows for me last summer and I want to do another 2-3 this coming summer so I’m hoping to talk to the guy I spoke to last time. The only slight problem I had was they left the garbage (I can't remember the technical term for what it was) on the side, but the next day they came and picked it up without my even needing to remind them. They’re really the best! I had done my patio door with another company and overall Thermo Bilt (especially Steve, the man who was in charge of the job) was the best contractor.

Window installation

They replaced my basement windows after I found their name in one of those flyers that have listings of renovation companies. I compared them to other companies and they had the same prices. The only problem I had with them was that they kept the stickers on the windows and I had to reach to take them off afterwards.
