I recommend Keystone highly. The sales process was easy and the pricing very competitive. I researched the manufacturer of the windows and they had good reviews. The delivery time was quick and the folks on the installation team were professional and friendly.

All around great job. It was not a big job, but they gave the same attention to me. They showed up every time on time from initial estimate to final install. The work replacing our windows was completed by a skilled professional. I love the final product!

Keystone was easy to work with from start to finish during our window replacement process. Steve answered all of our questions thoroughly and even made a second trip to our home to bring additional sample windows. The installation was quick, professional, and smooth. The installers were careful not to damage any existing trim work while removing the old windows and cleaned up thoroughly after the new windows were installed.

Great price, quality product, excellent service. Installation team was great and house was spotless inside and outside when they were done.

The price of the windows were fair and the installers were efficient and cleaned-up after they were done.

Wanna thank Keystone Window for the windows installed on 3/20/2024. The 3-person team arrived on time ready to go. Quietly and efficiently, they installed 5 windows in about 4 hours, a very professional job. And then they cleaned up afterwards. I purchased top of the line windows; the purchase price and installation were a great investment. Had windows installed in another part of my home by that other company that begins with an A, you've seen the commercials. They did a good job, but I got a better value with Keystone Window, without question. High quality windows, great price, professional installation. One other thing, the time from contract inception to installation was about 6-weeks vice 3 months with the other company. So, if your considering replacement windows, don't overlook Keystone Window. You won't be disappointed.

The installation was done with precision and expertise. The windows themselves were solid and very easy to open and close. I recommend Keystone Windows to anyone looking to improve their homes.
