These guys did a fantastic job replacing all my windows and sliding doors. They did a really great job with some beautiful interior trim I wanted. Their prices were great, the installation supurb. Being in the wholesales building material business, I knew many businesses that I could use.

The Window Guys installed 19 replacement windows & a sliding door at my house in 2011 (sorry for the late review). Jaz came out and gave the estimate. Everything was up front. I got a total of 5 estimates. They came down in price to match a competitor that was quoting another product. For what I got, they were the most reasonable. I'm very glad I went with the Milgard Tuscany series.

To The Window Guys, I just wanted to say thank you. We had 13 windows replaced on 9/16/2013 by this company. In fact they are finishing up as I write this letter. I was so impressed by the quality, cost and professionalism of the work and of employees AND of how beautiful my windows look that I had to let anyone and everyone know as soon as possible.
