Sliding windows are the perfect choice for rooms that need a little bit more ventilation than usual, such as bathrooms and kitchens. That’s why we’ve become the window company choice of homeowners seeking replacement sliding windows at affordable prices.

What Makes Sliding Windows So Cool?

A horizontal sliding window can add a touch of flair to any room that needs it, but this unique window type works well in kitchens and bathrooms. With their sleek design and easy-to-use operation, a sliding window can become a standout feature in any room.

Their large glass panes allow maximum natural light and unobstructed outdoor views, enhancing a room's brightness and ambiance. Sliding windows are low-maintenance, with fewer parts to repair, and their smooth operation makes them highly durable.

Plus, when working with Thermo-Seal, you can choose from wood, vinyl, composite, and aluminum windows to add charm and character to your home. A sliding glass window may be just what your home needs to get to the next level.

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."

"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."

"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."
