Window Company in Ontario, CA
Window and door work in Ontario, CA has to account for two things most cities don’t: Santa Ana winds that regularly push past 60 mph through the eastern edge of the LA basin, and a housing stock that spans more than a century of building styles. From original 1920s Craftsman bungalows near Euclid Avenue to 1950s steel casement ranches south of downtown and 1990s stucco subdivisions on the old farmland to the north, every block of Ontario asks something different of a window. We take that seriously. Call us at (760) 624-3669 and we’ll tell you straight what your home needs.
Why Ontario Homes Are Different
Ontario’s place at the mouth of the Cajon Pass means the city gets the full force of fall and winter Santa Ana events. Wind-driven dust and grit eat at weatherstripping, etch glass over time, and rattle older sashes hard enough to break the cords inside the walls. A window that survives a mild coastal breeze will fail here within two or three seasons if it wasn’t installed with those gusts in mind. We spec weatherstripping and glass packages for that reality, not for a generic Southern California afternoon.
The housing stock compounds it. Older homes in the historic downtown core and along Euclid Avenue were built with original wood windows, many of them double-hung units with rope-and-pulley counterweights. Those ropes fray, snap, and bind, especially after a wind event. Some owners want to restore the originals; most want the look without the maintenance. Meanwhile, the postwar neighborhoods south of downtown are full of steel casement and aluminum sliding windows that conduct heat straight through the frame, and the newer subdivisions built through the 1980s and 2000s often show door misalignment from settlement. Each call we make in Ontario starts with identifying which era the house came from, because that tells us most of what we need to know.
Our Main Ontario Services
Most Ontario homeowners reach out to us for one of three jobs: replacing old or wind-beaten windows, installing new windows in fresh construction or additions, or setting a new entry door that actually closes square and seals tight. Each is its own page with its own pricing and details.
Window Replacement in Ontario
Replacement work here usually means pulling out failed steel casements or tired aluminum sliders and putting in modern frames with glass rated for the way Ontario’s dust and wind behave. In the Euclid Avenue district, we’ve worked on Craftsman bungalows where the original double-hung wood windows have sash cords broken by Santa Ana rattling. The full breakdown, including what Ontario’s wind exposure does to your choices, is on the Window Replacement in Ontario page.
Window Installation in Ontario
New installation is a different animal from replacement: rough openings get measured, flashed, and sealed before the window ever goes in. In Ontario’s newer subdivisions where settlement has shifted walls out of square, that prep work matters even more. We verify each opening with a level and square before ordering anything. Details on process, pricing, and what to expect on installation day are on the Window Installation in Ontario page.
Door Installation in Ontario
Ontario’s dry heat and wind storms are hard on entry doors, and the settlement common in the 1980s and 1990s tracts north of the 10 means doors that once latched clean end up dragging on the threshold or gaping at the top. We set doors plumb, square, and sealed against dust and drafts. For specifics on products, timing, and written pricing, see the Door Installation in Ontario page.

What Ontario Customers Say

- Bethany Oh"Our sliding patio door had come off its track years ago and we just lived with it. New one is smooth as butter. They hauled off the old one and vacuumed up before they left."
- Jessica Landry"Replaced a big picture window that had a failed seal and was always foggy. Can finally see the yard again. On time, tidy, and they stood behind the install with a written guarantee."
