Meridian Windows & Doors is a window and door company serving Antioch, CA, with window replacement, window installation, and patio door installation.

We write the price down before any work starts and cover every job with a 365-Day Done Right Promise. If a window or door fails within a year, we come back at no charge. Call (817) 686-2228 for a free estimate.
Why Antioch Homes Are Different
Antioch sits on the San Joaquin River’s south bank, where summer temperatures regularly push into the 90s and low 100s. That heat load hits west- and south-facing windows hardest, and older single-pane aluminum frames with failed seals are common in homes built in the 1970s and 1980s. When the Delta breeze kicks in during late afternoons, it can swing indoor temperatures 20 degrees within an hour, which exposes weak weatherstripping and loose door seals fast.
The terrain matters too. Homes along the hills east of Deer Valley Road and up toward Black Diamond Mines sit on slopes with baked-clay soil that shifts seasonally. That movement can pull a window frame out of square over ten or fifteen years, which is why we check rough openings for level before any replacement goes in. Antioch also has a mix of HOAs, especially in newer subdivisions like those around the Lone Tree Golf Course area, and some have rules about window colors and door styles. We’ll flag that during the estimate so there are no surprises later.
Our Main Antioch Services
Most Antioch homeowners call us for one of two things: old windows that leak air and drive up cooling costs, or worn patio doors that stick, leak, or no longer lock properly. Here’s what each job looks like in Antioch.
Window Replacement in Antioch
Antioch’s summer heat exposes weak windows quickly, and we see a lot of failed seals and warped vinyl frames in homes that catch full afternoon sun. Replacing them means removing the old unit, checking the opening for dry rot or shifting from the clay-heavy soil, and setting the new window level before sealing it. We pull from eight manufacturer lines so the replacement is spec’d for the heat load on that specific wall, not whatever happens to be on the truck. Full details are on our Window Replacement in Antioch page.
Window Installation in Antioch
New construction and room additions in Antioch need windows set correctly the first time, and that starts before the framing is finished. We work with the general contractor or directly with the homeowner to confirm rough openings, flashing details, and sealant compatibility with the exterior finish. In Antioch’s newer developments east of Hillcrest Avenue, we coordinate with builders who need the schedule held, not shifted. The full scope is on our Window Installation in Antioch page.
Patio Door Installation in Antioch
Sliding patio doors in Antioch take a beating from expanding and contracting frames, and from Delta wind gusts that rattle loose rollers. We replace sliders and French doors, and when an old slider has chewed up its track, we inspect the sill and subfloor before setting the new unit. Homes with older aluminum sliders in the Gentrytown and Dallas Ranch areas often have undersized openings, so we correct the rough opening first. See the details on our Patio Door Installation in Antioch page.
