Window Company in Union City, CA
Replacing windows or doors in Union City is a different job than it is ten miles inland. The housing stock here dates heavily from the 1950s through the 1970s, and much of it still carries original single-pane aluminum frames that the bayside air has been working on for half a century. We’re Meridian Windows and Doors, part of the Garrison Partners family, and we approach every Union City job with the local conditions in mind: salty marine air, persistent afternoon winds, and homes built before modern sealing standards existed. Call (669) 201-3739 to talk through what you’re seeing.
Why Union City Homes Are Different
Union City sits on the eastern shore of San Francisco Bay, and that location shapes almost every window and door job we do here. The air carries moisture and salt, and the afternoon winds push both against west-facing walls. Aluminum frames corrode faster than homeowners expect. Weatherstripping dries out, shrinks, and stops sealing. Wood door frames swell in winter and pull away from the jamb in summer.
The housing stock adds another layer. Most of Union City’s single-family homes are ranch and split-level builds from 1950 to 1980. Many still have their original single-pane aluminum sliders, especially in the older Decoto district, where 1960s-era rollers are known to seize in the salty air. Homeowners in that neighborhood have learned the hard way that replacing just the rollers rarely holds up; the track assembly itself usually needs to go. On the newer west side subdivisions, the standard vinyl dual-panes are reaching the end of their service life in a different way, with seal failures showing up as fogging between the panes. The work here tends to be straight retrofit or full replacement, not new construction, and that is the market we know best.
Our Main Union City Services
Most Union City calls to us fall into one of three categories. Each has its own page with local pricing, timelines, and the specific conditions our crews see in this city.
Window Replacement in Union City
When an aluminum frame is corroded, bent, or no longer holds a seal, the fix is usually a full replacement rather than a repair. In Union City, the marine air means we spec frames and hardware rated for coastal exposure, not whatever is cheapest on the shelf. Low-E glass, which uses a thin coating to reflect heat while letting light through, makes a measurable difference on west-facing rooms that get hammered by afternoon sun. We also check the rough opening for rot and moisture damage before the new unit goes in. Details and local pricing are on our Window Replacement in Union City page.

Window Installation in Union City
Union City’s ranch and split-level homes often have unusual rough-opening sizes that were standard when aluminum frames dominated the trade. Installation here regularly involves custom-sizing the new unit to fit the existing opening rather than reframing the wall, which keeps the project cost down and the stucco intact. We flash and seal every opening to hold up against wind-driven rain off the bay. The full process, including what to expect on install day, is on our Window Installation in Union City page.

Patio Door Installation in Union City
Older Union City homes frequently have hollow-core sliding patio doors that have warped in the bay moisture to the point where they no longer latch or seal. Replacing them with a properly sized unit and a fresh track assembly changes how the whole back of the house feels and how it holds heat. We install sliding and French-style patio doors from manufacturers we trust to stand up to coastal conditions. For specifics on what we see in Union City and what a replacement runs, visit our Patio Door Installation in Union City page.

What pushes price up in Union City is usually frame corrosion that extends into the rough opening, requiring sill repair or flashing replacement before the new unit can go in. Wind-driven moisture has a way of hiding damage until the old frame comes out. Every job gets a written price before any work starts, and that price does not move at the door.

FAQs About Window Company in Union City
In most Union City neighborhoods, replacing an existing window or door with a unit of the same size does not require a permit. Changes to the rough opening, structural work, or new openings generally do. We handle the permit process when it is required, and the cost is written into the estimate before any work begins.
Most estimates in Union City happen within three to five business days of the call. Spring and fall are busier because the weather is mild and homeowners are thinking about energy bills. Call (669) 201-3739 and we’ll find the next opening that works for you.
No. The price we put in writing before work starts is the price you pay. The only exception is if we uncover hidden damage behind the old frame that changes the scope, and in that case we show you what we found, give you a revised written price, and wait for your approval before proceeding.
