Report
When planning to replace *every* window in my house and the sliding glass door, I got estimates from three different companies, including Thermal Windows. Not only was the Thermal Window estimate at least $10,000 less than the other two, I was impressed with the interaction when Taylor Harbert came out to the house. He explained information in language that was easy to understand, and answered all my questions thoroughly.
I did not feel pressured to make a quick decision, and when I emailed Taylor after his visit, he answered other questions that I had. It was also important to me that Thermal Windows is a local company that makes the windows it sells and that the installers are company employees, not contracted labor. The installation went well. The installers were courteous and careful when moving furniture to access windows.
The removal of the existing windows and ongoing clean up during installation was spotless! I LOVE my new windows, and my neighbors have complemented them as well. I would recommend Thermal Windows enthusiastically.

After shopping around for windows for quite a while, I called Thermal Windows and was blown away by their service. Donny was extremely knowledgeable and guided me through the entire process. The pricing was much better than I received from other companies, and the quality was far superior. Looking forward to saving money on my electric bill which will pay these off in no time. Thank you to Donny and the Thermal Window's team!

This company is outstanding and so are its employees. I had all the windows in my house replaced and the new ones are gorgeous! I live off an access road and the traffic noise is almost non-existent now. Taylor Harbert did my estimate and he was great. They were absolutely on time with everything. Junior, Raphael, Jesus and Eli did the install. They were fast but did an outstanding job on the install and they cleaned up beautifully. They were always on time. If I could give 10 stars I would. You can't go wrong with this company. A+++++++++++++

Rudy and Rafa replaced the windows in my house, and they did an amazing job. My family was able to instantly tell a difference. The aesthetics alone were worth it, but I no longer feel a temperature change while standing next to a window. It's fantastic. 10/10 highly recommend. Thanks! Service: Window installation

I could not be more happy with the windows. What a difference. Ruben and his crew have done a outstanding job so far. They are careful and gone above and beyond to install these windows. They are very clean and neat. They are credit to your company and the level of skill they have is a difference maker. John Toland the salesperson was very easy to deal with and was very helpful navigating through HOA approval. He was a pleasure to deal with. I am very glad we chose to go with your company. Thank you
