Window Company in Antioch, CA
Westlight Windows & Doors is the window company Antioch homeowners call when builder-grade windows finally quit. Most of the city’s housing stock went up between 1990 and 2007, which means thousands of homes are now running original vinyl windows and aluminum sliders that are 18 to 30 years old and failing in the same ways at the same time. The Delta gap wind that funnels through Antioch pounds window seals and door hardware daily, then summer heat cycles stress the frames even further. If your windows are fogged, sticking, or letting the afternoon gusts whistle through, call (903) 354-7134 for a free estimate with the price in writing before any work starts.
Why Antioch Homes Are Different
Antioch sits at a geographic funnel where afternoon Delta gap winds drive sustained 20 to 35+ mph gusts nearly every day. That wind does not just rattle panes. It pushes against glazing seals, screen frames, and door sweeps in a constant pressure cycle that neighboring Brentwood and Pittsburg simply do not experience at the same intensity. Pair that with summer highs that routinely crack 100°F while the coast sits in the 60s, and you get extreme thermal expansion and contraction on top of steady wind stress. The result: seal failure, frame warping, and track wear happen faster here than almost anywhere else in the Bay Area.
Then there is the housing stock itself. Antioch exploded with stucco tract-home construction from roughly 1990 through 2007, and much of that growth used builder-grade vinyl windows and aluminum-frame sliding glass doors. Those units are now aging simultaneously across entire subdivisions. The city also took a hard hit in the foreclosure crisis, which left a lot of that housing carrying years of deferred maintenance. In practice, that means we frequently replace windows and doors that should have been swapped out five to ten years ago.
One pattern we see on east-Antioch tract homes built 1998 to 2006: sliding glass doors with blown roller assemblies and shredded weatherstripping. The daily Delta wind cycle expands and contracts the frame against worn tracks until the rollers fail. When we quote a “sticky” patio door in those subdivisions, we include roller replacement and track realignment as a near-automatic add-on because the track wear is almost always already there.
Our Main Antioch Services
Most Antioch homeowners reach out about two things: replacing windows that have failed, and installing new doors or windows in a remodel or addition. Here is how each works here, with a dedicated page for the details.
Window Replacement in Antioch
Replacing windows in Antioch usually means pulling out builder-grade vinyl from the 1990s and early 2000s and putting in something built for the Delta wind. We walk each home, measure every opening, and match the right product to the exposure, including low-e glass (a thin coating that reflects heat back into the room in winter and out in summer) on sun-blasted west and south walls. The written price you get covers the full job, and you will have it before a single screw turns. Full details live on our Window Replacement in Antioch page.

Window Installation in Antioch
New construction or an addition in Antioch needs windows installed before the stucco and drywall go up, and the Delta wind does not wait for framing inspections. We coordinate with your contractor’s schedule, install to manufacturer spec so the warranty stays intact, and make sure every unit is plumb, level, and sealed against the daily pressure cycle from the gap winds. Our Window Installation in Antioch page covers the process and what to expect.

Door Installation in Antioch
Entry doors and patio sliders in Antioch take a beating from afternoon wind gusts and summer heat, and a door that is hard to latch or swollen shut is often a sign the frame has moved. We install entry doors, storm doors, and sliding glass doors from trusted brands like Therma-Tru, with weatherstripping and thresholds sized for our wind and heat. See the Door Installation in Antioch page for the specifics.

What Antioch Customers Say
"Got quotes from three companies. Westlight wasn't the cheapest but they were the only one who measured everything carefully and put it all in writing. Worth it. No surprises on install day."
- Craig Dillard"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 eight drafty old windows that were basically single pane. The house is warmer already and the street noise is way down. Crew was on time both days and the price was exactly the quote."
- Harold Bemis
