Glendora Window started in 1989 as a one-person handyman service. Word spread. Work followed. Today the same family runs the shop on White Avenue, doing the same craft — only better.
It started in 1989 with one man, a truck, and a willingness to fix what other shops told customers to replace. The phone kept ringing. Four years in, we focused entirely on what we did best — windows, glass, and screens.
By the late 1990s the founder's son had joined the shop. By the 2010s, a third generation was learning the trade. Today, the same family answers the phone, does the measure, cuts the glass, and stands behind the install.
We're on White Avenue in La Verne. We've resisted the temptation to franchise, sub-contract, or chase the easier work. The slow way is the right way.
Repair before replace. About 80% of the windows people assume are dead are actually fixable in an hour or two. We'll tell you when that's true. We'll also tell you when it's not.
The same crew, start to finish. The person who measures will be the person who installs. No subcontractor handoffs. No 1-800 warranty calls. If something fails in year five, you call us.
A real estimate, not a sales pitch. We don't push financing, upsells, or unnecessary upgrades. Free quotes by text, email, or walk-in. No obligation.
Show up. Stand behind it. We pick up the phone. We do what we say. When something doesn't go right — rare, but real — we fix it.
Our shop on 1782 N White Avenue has been open Monday through Friday, 8am to 5pm, for as long as most people can remember. Bring in a screen, a broken pane, or just questions. No appointment needed.
We keep wide stock for standard residential and commercial glass — single-pane, double-pane, tempered, low-E, obscured, custom shapes. Mesh in every common type from standard fiberglass to stainless-steel security. Hardware, springs, latches, rollers, and weatherstripping for most major window brands.
If we don't have it in stock, we cut from sheet glass or order it in within days.
Walk in to the shop, call (626) 335-2900, or text a photo for a same-day quote. We'll respond within two hours during business hours.
