What Our Clients Are Saying

We strive to make the entire home remodeling experience positive for our customers—from your first phone call, until the final handshake.

"I had a very good experience with Thermo-Seal.  Chose them after interviewing many others because they're local, communicated efficiently, and offered good midrange pricing and lifetime warranty. The crew did a fantastic job with the installation. They came early and finished 5 windows in 5 hours, and then they cleaned up. Highly recommended!"

"We just completed a window and siding job for our home with Thermo-Seal. We are very impressed and satisfied with the quality of their products as well as the installation. I would recommend this company & I would use them again in the future if needed."

"The crew was a pleasure to work with, and we love our new windows. The installation was efficient, and the team was very professional. I’ve seen a difference in my heating bill since the install, which was our primary goal so we are very happy so far! I will work with Thermo-Seal again for a front door replacement when the time comes."

You can tell they take pride in their output and ensure things are done correctly the first time around. The project completed ahead of schedule and we were kept in the loop the entire time. Very happy with their work and highly recommended!"

"We were referred to Thermo-Seal by a neighbor who was very pleased with the results. We replaced seven windows and a sliding patio door are thrilled with the results and how much they enhance the appearance of our home. Without hesitation, we recommend Thermo-Seal for your home improvement projects."

Frank D.

"Cannot believe how stress-free an experience it was dealing with Aaron and his team. Aaron was very patient with our multiple questions and never any sales pressure. The installation was clean, quiet and the installation team friendly and helpful. The windows were installed a few weeks before they were promised and there were no surprises. We will be strongly recommending Thermo-Seal to friends looking for replacement windows."
