Glendora Window started in 1989 as a one-person handyman service. Word spread, work followed, and four years later we focused entirely on what we did best — windows, glass, and screens.
Our shop is now on White Avenue in La Verne, and we've been serving the East San Gabriel Valley for 36 years. The same family still runs it. We answer the phone, we do the work, we stand behind the install.

UplandWhat neighbors have to say.
“We had the stationary part of a dual pane, low-e window get broken. Friendly installer. Super fast estimate, measurements, delivery and installation. Measured twice to assure perfect fit. Fair price, quality product, expert installation, insurance approved.”
“They were both so meticulous in removing the slider door and installing new wheels, cleaning out the rails and reinstalling and making sure everything lined up… I can now open and close both slider and screen with one hand. I love and appreciate the work they did.”
“I called this company for service and their response was incredibly fast! They didn’t stop there. They offered flexible options for giving me an estimate and getting the work done and the crew was highly professional and courteous.”
