Rated 5 out of 5 by from These Guys Get The Job Done! I had 8 retrofit windows, 3 Sliding glass doors and 1 exterior door installed. About 6-7 guys showed up and 6 hours later all work was completed! I was very impressed. Every one got down to business right away. The installers were helpful and professional. I would highly recommend this company for your windows and doors project!

Rated 4 out of 5 by from Sales Team & Intallers were awesome. Office staff is lacking. Bill who provided the consultation and quote was excellent. Installers did an awesome job. I really appreciate them taking extra time to hang my blinds after installation. I love my Milgard windows and will be contacting The Window Guys to do the other half of my home in the near future. The only area where they could use improvement is the office staff. The girl who scheduled the appointment and answered the phone when I called to make my down payment was rude and didn't seem well trained. When I called she couldn't even find my quote and by the time she emailed me the info to pay it was several days later and I had already gone in personally to give my deposit. Customer service & polite front office staff goes a long way so if The Window Guys improves in this area I would give 5 stars.
