I have only the highest praise for Keystone Window. I met with five different vendors when I decided to replace my windows and with each I felt somewhat uneasy that I was being taken advantage of. I dealt with pushy salespeople, pricing that was anything but transparent, and so many choices in materials that I was left with my head spinning. After a family member heard a radio ad for Keystone I decided to add one more vendor to my list and I’m so glad I did. Mike, the salesperson, came out to my condo on a Sunday morning and was extremely courteous and very straightforward. Keystone’s pricing came in thousands of dollars under the quotes provided by other vendors but the quality didn’t suffer. And to top it off, they were able to install my windows early (4 weeks after measurements were taken vs. the 5-8 weeks estimated). I’d highly recommend Keystone!Kaitlin B. of Philadelphia, PA
