Client Reviews

I didn't hesitate to call Alton when I had to replace my side door and window. I had used them before and had exceptional service and was happy with the end result. I highly recommend them.

You know it's a good company when the owner shows up! We needed an emergency repair for a window we bought 20 years ago. We called the company, and the owner, John personally came over within :30 to fix it. That says it all about their great customer service.We've bought several windows and doors from Alton, always great advice, service and fair price.

Amazing service and love love love my windows! Went in 2 weeks ago and it was a great experience from start to finish. I read the previous review regarding the Mandated Health & Safety Guidelines and I can’t believe the comment. I was actually asked to return to my car and get my mask (was rushing and I forgot it) also I was asked to wait 6 feet away from the other customer that was at the front desk. I felt very satisfied with how they followed Health & Safety regulations. I would definitely recommend this company to anyone.
