Thermal Windows

"Thermal Windows is the best window manufacturer and installer. No finger pointing if there is an issue. Cole White was our sales guy that showed us the windows and gave us a tour of the manufacturing site. He was great! The installers were great too. They took their time to do the job correctly and insulate and seal all the way around. We will get the rest of the windows to finish the house out later on. This was one of the best experiences ever! We love the new windows and patio door! Thermal Windows manufacturers and installs high quality product!"

"It’s been six years since Thermal Windows and their crew installed our high-quality windows, and they have held up beautifully. What really impressed me, though, was their recent service. We had an issue with our sliding glass door, and when the team came out, they didn't just do a quick fix. They identified a need for extra reinforcement underneath the door to ensure it stays solid for years to come. They handled the entire repair and the extra reinforcement completely under their warranty. The crew was professional, clean, and courteous. It’s rare to find a company that provides this level of support and quality long after the initial job is done. Their customer service is truly second to none! I cannot recommend them more highly."

"This is an awesome company. Not only do they have fabulous products, they also take care of their customer base. We had to install windows from another company approximately 10 months old and they walked us through all the problems we had. We are again enjoying our home with the NEW Thermal Windows and what a lovely addition they are! Our home will be more cost efficient with energy bills. The patio door is absolutely fanastic as well. We would like to give a shout out to Cole. He was most helpful during the process and made this company stand out from day one. He is very knowledgeable and such a pleasant salesman. When you find a product made in Texas with their own installation crew you have found the best of both worlds. This was the BEST choice we made in 2025 to replace windows using them. Much thanks to Cole, Ruben and Lustavo. Amazingly done! Lucy was a great help as well. Just wow.....what a difference their products are making."
