Excellent work ethic, on time and very efficient The crew that was sent out was enough people to do the job in the time they said it would take. They just did not send out a couple of people and say this is what we have to work with. October 3, 2014

This a professional window install From the minute the Window Guys started the job till the finished Job it was a unusual experience. The guys all had their job to do and everything was completed as they said it would. They worked neat and clean and it was as if they had never been here when they left.I have recently referred them to two of my friends. The Windows are very well made and look and operate as I was told. I couldn't be happier . Thanks to the Window Guys!!!!~ June 26, 2014
