Patio Door Installation in Union City - Written Price Before Anything Is Ordered

Fast, Reliable Patio Door Installation Across Union City

Patio door installation in Union City runs $2,800 to $7,600 for a standard sliding glass door replacement, and most jobs wrap up in one to three days once the permit clears. We serve every part of Union City, from the Decoto district to the eastern foothills off Mission Boulevard. Our team knows the housing stock here. We’ve worked on 1950s ranch homes with original 5-foot sliders and newer two-story builds that need heavier-duty framing. Call (817) 686-2228 to get a written price before any work starts.

The thing about patio doors in Union City is that two homes on the same block can need completely different work. A ranch off Whipple Road might have a 5-foot slider with a shallow header. A hillside house off Dyer Street might need lateral-load-rated framing and a 6-foot unit to meet egress code. We scope the job against the actual structure, not a catalog photo. That’s why our written quotes hold. No one from our team shows up and changes the number at the door.

Why Meridian Windows & Doors Is Union City’s Preferred Patio Door Installation Company

We’re part of the Garrison Partners family, and we’ve operated to The Garrison Standard since 2009. That standard is simple: show up when we say we will, put every price in writing, and stand behind the work for a full year. In Union City, that’s what separates a crew that finishes the job from one that disappears after the deposit.

Elliot Vance leads our Patio Door Installation team, and he’s particular about the details that matter here. Sill flashing is the big one. Union City gets real winter rain, and a door that leaks is almost always a flashing failure, not a door panel failure. We check the rough opening, the header, and the sill pan before we quote. Then we write it down.

Every technician who walks onto a Union City property is background-checked and in uniform. You’ll know exactly who’s at your door. Our phones are answered by a live person around the clock, every day of the year. No voicemail loops. If you call at 2 a.m. with a question about your quote, a person picks up.

Sliding Door Installation in Union City

Sliding Door Installation in Union City means replacing an existing patio door or cutting a new opening, and the most common request we hear is swapping a tired aluminum 5-foot slider for a wider 6-foot vinyl or aluminum unit with low-E insulated glass. The job starts with measuring the rough opening, checking the header depth, and confirming the sill is structurally sound. In Union City’s Decoto neighborhood, many original openings were framed for 5-foot doors. If you want a 6-foot slider, the opening needs reframing. That’s a bigger scope than a direct swap, and it changes the permit requirement.

Replacement Sliders for Older Ranch Homes

A direct replacement on a 1950s or 1960s Union City ranch typically runs $2,800 to $4,900. We pull the old frame, inspect the sill plate for rot, and install the new door with proper flashing at the sill and jambs. If the original header is undersized, we sister in additional framing before the new door goes in. Skipping that step is how you get a door that binds within two years.

New Openings and Wider Doors

Going from a 5-foot to a 6-foot slider, or cutting a brand-new opening, runs $5,200 to $7,600 in Union City. This involves reframing the wall section, installing a properly sized header, and pulling a permit with the City of Union City. We handle the permit drawings and the inspection coordination. The work typically takes two to three days including the stucco or siding repair around the new frame.

Patio Door Repair in Union City

Patio Door Repair in Union City usually falls into three buckets: a door that sticks or is hard to slide, a door that leaks during winter storms, or a fogged glass unit that needs replacing. Most repairs run $180 to $950 depending on what’s actually broken. A worn roller assembly on a sliding door is a $180 to $350 fix. A failed low-E glass unit runs $400 to $900 installed.

Sticking Doors and Roller Failures

Older aluminum sliders in Union City ranch homes have rollers that wear out and score the track. We replace the rollers, clean and realign the track, and adjust the door so it slides with one hand. If the track itself is bent or corroded, we replace the track section. That’s a half-day job in most cases.

Leaks and Sill Flashing Repairs

A patio door that leaks during Union City’s rainy season is usually a sill-pan problem. The door itself may be fine. We remove the door, inspect the flashing at the sill, and reinstall with proper pan flashing and sealant. On a Decoto-area home, we often find the original installers skipped the sill pan entirely. That’s a $350 to $950 repair depending on how much of the surrounding framing has water damage.

Trusted Brands We Service in Union City

We’re authorized to install and replace patio doors from PGT, CGI, and CWS, among others. That means we can match what you already have or upgrade to a door with better wind resistance and thermal performance. Our installer team at Union City keeps common replacement parts in stock, which cuts down the time between diagnosis and repair. If your existing patio door is a PGT unit, we can source the exact replacement glass and hardware without waiting for a special order from the manufacturer.

Common Patio Door Installation Problems We See in Union City Homes

• Original 5-foot openings in Decoto ranch homes that were never framed for a wider door, forcing a smaller replacement or a full reframe. Union City’s older housing stock is full of these, and a direct swap often means settling for a door that’s narrower than what the homeowner actually wanted.
• Failed sill flashing that leaks during winter storms, misdiagnosed as a door problem when it’s actually an install problem. The heavy seasonal rain Union City gets means a skipped sill pan shows itself within a year or two, not a decade.
• Fogged or failed glass units in doors facing the bay side, where temperature swings stress the sealant on older units. A fogged door on the south-facing side of a Union City home is usually a sealed unit failure, not a cleaning problem.
• Undersized headers above existing sliders that were fine for a 1950s aluminum door but can’t handle the weight and loading of a modern double-pane unit. We see this on hillside homes where wind loading is higher than the original framing anticipated.

FAQs About Patio Door Installation in Union City

Do I need a permit to replace a patio door in Union City?

Yes, if the replacement changes the opening size, header, or egress configuration, or if you’re adding a new opening. Union City requires permits for those scopes. A direct 5-foot for 5-foot swap in an existing opening may qualify as a like-for-like replacement, but we confirm with the city before we quote. We pull all permits and coordinate the inspections. Call (817) 686-2228 and we’ll tell you exactly which path applies to your door.

My old patio door sticks and leaks during rain. Do I need a full replacement or just a repair?

It depends on what’s actually wrong, but here’s the honest read: a sticking door with a worn roller assembly is a repair, typically $180 to $350. A leaking door that has a failed sill pan is also a repair, typically $350 to $950. But if the glass is fogged, the frame is corroded, or the header is sagging, a full replacement is the better long-term play. We’ll diagnose it at no charge and put both options in writing. Call (817) 686-2228 to schedule the inspection.

Can you replace a 5-foot patio door with a 6-foot slider in an older Union City ranch home?

Yes. This is one of the most common projects we do in the Decoto area, where original openings were framed for 5-foot sliders. The job requires reframing the opening, installing a properly sized header, and pulling a permit with Union City. Total cost runs $5,200 to $7,600. The work takes two to three days including the exterior finish repair. Call (817) 686-2228 for an exact quote on your specific opening.

How long does a patio door installation take in Union City, from first visit to final inspection?

A direct replacement in an existing opening typically takes one day on site, plus a few days to a week for the permit to clear if one is required. A job that changes the opening size takes two to three days on site, plus permit review time with Union City, which varies by season. From first visit to final inspection, most Union City patio door projects wrap up in two to four weeks. We give you a written timeline with the quote. Call (817) 686-2228 to get your project on the calendar.

What actually changes the price once you open up the wall on a patio door job?

Three things. First, hidden water damage or rot in the framing around the old door, which has to be repaired before the new unit goes in. Second, an undersized header that wasn’t visible until the wall was opened, requiring additional framing. Third, a failed or missing sill pan that needs to be retrofitted. In Union City’s older ranch homes, we see all three regularly. We identify as much as possible before we quote, but the wall always has final say. Our written price includes a line-item scope, and any change is put in writing and approved by you before we proceed. Call (817) 686-2228 to get an honest quote on your Union City patio door.
