Keystone Window replaced three windows and window trim in my bedroom. One of the windows was improperly installed and the installer used excessive exterior caulk all over the window trim. They refuse to make the repairs.

I got estimates from a few window companies and they were very expensive. Keystone Window had a much better price. Everyone from the salesmen to the installer did a good job. They are fantastic windows. The quality is very good and it is the best thing I've had done to my home in a while. I tell everyone who is looking for windows to call Keystone.

Sales Knowledge - The guy who came was good, very friendly.
Problem Resolution
Problem Resolution - We had a couple of problems, but the owners solved them. The owner was great and the best part of the company. The best part was the owner came to my house personally and measured the window. He promised everything he had said in his commercial, and that was the best part. He never reneged on anything.

Overall, I thought their quality was exceptional. I like the 50-year warranty on the windows. I was very pleased with their service and I had compared them to competitors. They were definitely just as good of quality as any other competitor that I had looked at.

Why Choose Keystone
Why Choose Keystone - Renewal by Anderson & Pella Windows is who I got estimates from. I chose Keystone because they were less than half the cost for the same windows. They didn't play the games like how Anderson does. They say if you do the job by this date, we will give you this much off. Rob came out, gave me the price and stuck by it. I like dealing with facts and transparency rather than playing games.
Areas Of Satisfaction
Areas Of Satisfaction - The installers were fantastic. I love the windows. The capping on the outside was done very professionally.

The job was done very efficiently and better than I expected! They did 110% more than I expected.
Review of A.J. Perri (Service) by J.V.D.
Our problem was not terribly serious, but probably might have become so. We called, were given a time of technician's arrival, and set about to wait. Lo & behold, we got a call that we were being moved up on the list as the technicians were finished ahead of time--that worked so well for us. We kn... more
