        Overall

        Great experience with Keystone Window. I needed to have several new windows installed in a house that I was renovating to resell. Rob's price was extremely competitive, and he was the only window salesperson I ever dealt with that didn't try to use high-pressure sales. The installation went very smoothly, and we we're very happy with the entire process. Would definitely buy from again.
