Window Company in Union City, CA
Meridian Windows & Doors handles window replacement, new window installation, and patio door installation in Union City, CA. Most Union City homes fall into two camps: 1960s – 1980s tract builds with original aluminum-frame windows, and newer infill construction with builder-grade vinyl. Both leak air and let heat through, which matters in a city where summer afternoons routinely cross 85°F and the marine layer rolls back in by evening. We write the price down before work starts and cover every job in writing for 365 days. Call (817) 686-2228 for a free estimate.
Why Union City Homes Are Different
Union City’s position on the east side of the San Francisco Bay means windows and doors get hit from both directions. The afternoon sun off the hills bakes west-facing glass, and the evening breeze off the bay pushes damp, salty air into every gap around a frame. We see fog-related moisture problems here more than a few miles inland: swollen wood sashes, corroded aluminum tracks, and mildew where a patio door meets the slab.
The housing stock is the other half of the story. Streets around Decoto Road, Alvarado-Niles Road, and the neighborhoods east of Mission Boulevard are full of ranch homes from the 1960s and 1970s. Those original single-pane windows are now 50 to 60 years old. The seals fail, the frames rack out of square, and the glass transmits heat like it isn’t there. Newer subdivisions near Union Landing and the areas west of I-880 tend to have vinyl windows from the 1990s or 2000s, which fail differently: warped sashes, broken balance springs, and fogged double-pane glass. When we quote a job in Union City, we match the replacement to what the house actually needs, not what a catalog says fits a generic California home.
Our Main Union City Services
Most Union City homeowners call us for one of two reasons: a window has failed and needs replacing, or they’re planning a project where new windows or doors go into new openings. Here’s how each works here.
Window Replacement in Union City
Replacing an existing window in Union City usually means pulling an old aluminum or vinyl unit and setting a new one into the same opening. The job goes faster when the framing is sound, which is true of most of the 1960s and 1970s ranch homes around town. What slows things down is rot: a window that has been leaking fog or condensation for years often has water damage in the sill or the framing beneath it. We inspect for that before we quote, and the written price covers any standard repair to the opening. See Window Replacement in Union City for the full breakdown.

Window Installation in Union City
New-construction window installation in Union City applies when an addition goes on the house or when a solid wall becomes a window wall. This is different work from replacement: the rough opening gets framed, flashed, and sealed from scratch. Union City’s marine air makes flashing especially important, because a poorly flashed new window will show moisture staining within the first rainy season. We use the same written-price rule on new installs as we do on replacements, and the 365-Day Done Right Promise applies in full. Details are on the Window Installation in Union City page.

Patio Door Installation in Union City
Patio doors in Union City take abuse from fog, salt air, and sliding tracks filled with dust from the hills. A typical job replaces an old aluminum slider with a new unit that seals tighter and rolls easier. We also install hinged French-style doors where a swinging door makes more sense for a yard or deck. The key local concern is threshold sealing: many Union City patio doors sit on concrete slabs that have settled over decades, and the gap between slab and threshold is where water and drafts get in. Patio Door Installation in Union City covers what to expect.

What pushes a Union City price toward the top of a range? Rot repair in the opening, second-story access, stucco work around the frame, and lead-time premiums on impact-rated glass. What does not change the price is a technician who arrives and decides the job is worth more: the number we put on paper before work starts is the number on the invoice.

FAQs About Window Company in Union City
Most like-for-like window replacements in Union City do not require a permit, but new-construction openings and certain patio door projects do. We handle the paperwork on jobs where a permit is required and coordinate inspections as part of the written scope. Call (817) 686-2228 with your address and we’ll tell you what applies.
Scheduling depends on the season and the scope, but standard replacements are usually scheduled within the same week. Larger projects, like a full-home replacement or a new patio door opening, are booked further out because the work takes more than a day. Phone coverage is live 24/7, so you can reach someone to talk through timing any day of the year.
No. The price goes on paper before any work begins, and it does not move at the door. If we find hidden rot or framing damage when the old window comes out, the standard repair is covered by the written scope. If something outside that scope is discovered, we stop and get approval in writing before proceeding. Call (817) 686-2228 for an exact quote, free of charge.
