What Our Customers Are Saying...


Thomas Hensley
I want to start with the fact that I did alot of research on windows and companies. I choose Sterling Windows because of their promise of great product and price. I was not disappointed. They went over and beyond in their timely and expert windows and service. The windows are unbelievable and the service from the staff at the office,sales people, to their installers was one of the best experiences that I have ever had. They worked in the cold and snow. They showed up early and stayed late. Please do yourself a favor and look no further then this company and these people. I own the Cook Loft in downtown Knoxville. feel free to come by and check out the GREAT job they did. Feel free to call me if you have any questions about these folks. They are the only ones I will call if I need any further help. Thanks guys.
