Got 6 windows installed, 5 casement windows and one awning window with frosted glass. The install went great, was done in a single day, and the guys were all really nice. We did have an issue with one window, I called their service line and they had people out same day to fix the issue to beyond my expectations. You can measure a company with no mistakes, but the REAL measure of a company is what they do and how they act when a mistake does occur, these guys knocked it out of the park. I will be calling them first when it comes time to replace my horrible basement door!

I can't say enough good things about Thermo Twin. They answer the phone, came right away, and gave us a fair quote. The 6 windows were ready two months ahead of schedule. The workmen were thoughtful and hard working. They cleaned up after themselves, to the point where, with the exception of new beautiful windows, you would never know they were there. If you need new windows, call Thermo Twin. We called others but none could hold a candle to them!

From the sales call to the installation finish, we are extremely satisfied with Thermo Twin's service. Nunzio is a no-pressure salesman and he answered all of our many questions. The team who installed our 10 beautiful windows was excellent, and accolades to Russ Groon (not sure of spelling) and the crew. They are professional, helpful, respectful, prompt, and we appreciated their approach to getting the job done with precision. We would highly recommend this company. Also I'd like to mention "Debbie" who was on top of the scheduling. All in all, a great experience.

We selected Thermo Twin windows for our home being built in Pittsburgh. We wanted to support a local business. The windows seem high quality, which we will see with time. The issue we had with Therm Twin was that they were quick to accept the order with a 4wk quote for delivery. The order partially delivered in 4 wks, with the remainder back ordered. After a series of mistakes, on their part, the order was finally fulfilled almost 16 wks later. The delivery caused delays in our construction and extended our stay in a rental. I am not impressed with their customer service nor "sense of urgency
