Over 37 years. One promise.
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.
"They fixed a foggy double-pane window I thought was a goner. Same week, fair price, and the install crew was so respectful of the house. Won't go anywhere else."
"Texted a photo of a broken slider on a Tuesday. Had a quote by lunch. Glass on Friday. These guys are old-school in the best way."
"36 years for a reason. They walked me through repair vs. replace honestly — saved me about $800 and the window works better than it did when we moved in."
