Desmond and Company did my installation? They came back a couple days later when the weather warmed up enough to paint the outside to match! These guys are the best! They both volunteered!@

I found out about Window Depot from my local home show and start to finish the process was great. They gave me a more than fair price and communication was good. Steven and his associate did a quick, clean job and the windows look fantastic. More importantly, I can already feel a difference in the temperature in the house. My old windows were original to the home and made out of aluminum. With these new ones even my south-facing window is cool to the touch despite the 100 degree temps the last couple of days.

Nick(salesman) was great to work with and easy to communicate with from start to finish. Steve and John(installers) were prompt and great guys to be around during the 3-4 day installation process. All of the windows and caps look great and the mess from the windows was extremely minimal. Would recommend over and over again!

I have had the pleasure of working with this company for the past 7 years from a referral from my parents who have also used this company. Our roof was damaged from hail in 2017-2018 and this company took care of everything in dealing with the insurance company and myself. I would hire them again for roofing and windows without hesitation. I’ve called Dylan multiple times out of the blue for random things that have come up and he’s always answered or got back to in a timely manner and fixed the issue or set my mind at ease. I just can’t say enough good things about this company. Hire them!
