What Our Customers Say
Carmen Ross
We love our new windows! They feel more solid and weather tight than windows we had installed last year with someone else. It was freezing the day they worked but they still got all the old windows out and new installed...
Kyle Adams
I highly recommend Johnny and his team for not only windows and doors, but also exterior deck work. When they began work on the deck, they notice more rotting than originally anticipated, and relayed that the deck needed to be a complete rebuild...
Harley Palmer
Johnny at window depot was great, very professional and courteous! He came in and measured everything very quickly, had it ordered and got us a fantastic price. I will be recommending his work to friends and family. 10 out of 10 wonderful experience!
Megan M
Window Depot of East TN was absolutely phenomenal to work with. I have a fixer upper that needed all new windows. This house was a train wreck, and I didn't even know where to begin. Johnny was super considerate and took his time explaining all my options...
Daniel Stringer
Fantastic company! Johnny genuinely cares about his customers and takes the time to educate them about his products. I recently found out that they offer more than just windows—they also provide siding, doors, gutters, decks, sunrooms, and more!
Corey Freels
Johnny and team were great. Showed up on time and delivered on budget, and was quick about taking care of a door that didn’t work correctly. Highly recommend.
