Rated 1 out of 5 by from VERY disappointed.. A six month process to replace 3 windows finally ended yesterday with us cancelling the project. Estimates for wrong items, inefficiency of estimator, wrong windows delivered for installation with no explanation...too many snafus. Installer, Luis, was a true professional, owner was personable but so many errors in one order caused us to lose confidence in letting the company do any construction on our home

Rated 5 out of 5 by from Happy Customer We had our windows and sliding door installed on May 13/21. I’m very happy with them. I have a mobile home and the noise from outside has been much quieter. They installed a wood frame around the sliding door and looks beautiful. The screen can lock from the inside I also had a key hardware installed on the sliding door. Installers took away all the old windows and glass. They were very professional and respectful of property. Office staff were always helpful as well. I’m very happy with my new windows. I would highly recommend The Window Guys.

Rated 1 out of 5 by from Scratched glass I love my new French doors and the guys that installed them did a great job But...both doors have scratches on them! The one side has three big scratches in the glass that I didn’t see until I was on a ladder painting the stucco around the door. Is it bad quality control? Or did the installers do it? One of the screens on my sidelight has a hole but I was told a new screen is on its way. It’s bittersweet, I love my new doors but all I see when I look at them are the scratches.
