Rated 5 out of 5 by The WindowGuys were professional, timely and excellent in the installation of my windows and garden window, The WindowGuys were professional, timely and excellent in the installation of my windows and garden window. Their prices were competitive. I was very impressed with the workmanship and highly recommend them to others looking for Milgard Window installers. July 8, 2014
Rated 5 out of 5 by Outstanding Company and Quality Installation!! We just had 12 Milgard Tuscany Windows and a Milgard Tuscany Sliding Door installed by "The Window Guys" on July 25, 2016. Wow, are we ever are glad we used this company. The salesman who quoted us named Bill was very knowledgeable about quality Milgard products and about his company qualifications. He was not pushy either. Their prices are great and $75 installation per window is really unbelievable. We used the Hero Program and we are so pleased with our awesome new windows and patio sliding door. The three installers, Aurelio, Sergio and Chava, were the best team of installers we have ever had do work for us. My wife and I are in our 60's so we have had work done at our home many times. These three guys were so professional and skilled in what they did it was amazing to watch them. Top of the line for sure. I highly recommend this company and of course the quality and wonderful Milgard Tuscany product line! A Very Satisfied Customer!! Steve from Moreno Valley. July 28, 2016
Rated 5 out of 5 by very professional, very efficient I had all of my windows and sliding glass doors replaced. They showed up on time and got right to work. It was impressive to see how efficient and fast they were. They did a beautiful job installing everything. They left the house as clean as it was when they came. Watching them work I realized how important it is to hire a company that knows what they are doing. They did not need to hesitate to figure out what to do. It looked like it was second nature for them. April 27, 2016

Rated 5 out of 5 by 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
