Fast, Reliable Gate Repair Across Union City
Gate repair in Union City typically runs $180–$650 depending on whether you’re looking at hinge work, post resetting, or full motor replacement, and most jobs are diagnosed and repaired same-day.

We’ve been driving the 880 corridor to Union City for sixteen years, and we know the difference between a quick hinge adjustment and the deeper structural work these flatland properties often need. From the older Decoto subdivisions off Whipple Road to the bay-edge Alvarado district near the old shoreline, we’ve reset posts, rewelded ornamental iron, and recalibrated openers on hundreds of Union City gates. Our Gate Repair team doesn’t subcontract — Kevin handles the diagnosis and the fix himself.
Union City’s housing tells a story: 1960s through 1980s tract homes with original wrought-iron driveway gates that have survived four decades of salt air and clay soil heave. Those gates deserve repair by someone who understands both the metal and the ground beneath it. That’s why Union City homeowners call us back.

Our reputation in Union City is built on showing up and fixing what’s actually broken — not upselling a full replacement when a post reset and weld will do.

From the Decoto neighborhood near the Union Landing shopping center to the residential streets off Alvarado Boulevard, our response time averages under an hour for standard calls and same-day for emergencies.
Our Gate Repair Services in Union City
Post Repair & Re-Setting
Post repair is the most common gate service we perform in Union City, and it’s not close. The flatland neighborhoods — the former Alvarado and Decoto communities — sit on bay-adjacent fill and expansive adobe clay soils that swell and contract dramatically through the wet-dry seasonal cycle, routinely pushing gate posts out of plumb and cracking concrete footings. Every gate repair job in 94587 effectively has two failure modes working at once: soil movement below and salt corrosion above.
We serviced a 1970s-era ornamental iron gate in the Alvarado district near the old bay shoreline. Salt corrosion had eaten through the bottom of both leaf hinges, and seasonal clay heave had shifted the post 1.5 inches out of plumb. We reset the post in a 36-inch footing, welded new galvanized hinge brackets, and recalibrated the LiftMaster operator. Shallow 18-inch footings from the original 1970s construction are no match for this soil — local technicians know to budget for re-digging and resetting posts to 36+ inches rather than simply rehinging or adjusting the gate leaf, because the post itself has typically moved an inch or more.
Gate Realignment
When a gate post tilts, the entire leaf goes with it. We’ve realigned hundreds of Union City gates where the automatic opener was “malfunctioning” but the real culprit was a post that had drifted half an inch, throwing travel limits out of spec. Seasonal soil moisture changes cause automatic gate travel limits to drift out of calibration by spring, leading to gate stalling or impact with stops. We check the structure first, then the electronics — not the other way around.
Weld Repair & Rust Treatment
Positioned directly on the eastern shore of San Francisco Bay, Union City receives consistent salt-laden marine air that corrodes uncoated steel and iron gate hardware significantly faster than cities even a few miles inland toward Fremont’s foothills. We see rust-through at ornamental iron welds on 40–60 year old Decoto and Alvarado gates every week. Our in-house welding capability means we cut out corroded sections, fabricate replacement pieces, and apply protective coatings on-site — no referral to a separate metal shop, no two-week delay.
Hinge Repair & Replacement
Hinge failure in Union City is almost always secondary. The hinge didn’t just wear out — the post moved, or salt corrosion attacked the pin and bracket simultaneously. We replace hinges with galvanized hardware sized for the actual gate weight, and we always check post plumb before calling the job done. A new hinge on a leaning post fails again in eighteen months. We’ve seen it.

Trusted Brands We Service in Union City
We stock and service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule — nine brands, most local competitors carry two or three. For Union City customers with automatic gates, that breadth matters: a 1990s DoorKing system in the Decoto district doesn’t need replacement because a technician doesn’t recognize the board. We carry common FAAC and BFT hydraulic parts, Linear and Viking slide-gate components, and Ghost Controls solar-compatible hardware. When your opener throws an error code or your gate stalls at the same point every cycle, Kevin’s fluency across these nine systems means faster diagnosis and repair without the “we’ll have to order that” delay.
Common Gate Repair Problems We See in Union City Homes
- Posts tilted by clay soil heave. The wet-season rain concentrated November through March saturates Union City’s heavy clay flatland soils, causing measurable post heave that technicians find has thrown automatic gate travel limits out of calibration by spring. We check post depth and plumb before touching the operator.
- Rust-through at ornamental iron welds. Salt-laden marine air from the Bay rusts through welds and uncoated hardware on older ornamental iron gates faster than in inland cities. We see this on 1970s-era Decoto gates where the bottom rail has separated from the pickets entirely.
- Automatic gate stalling mid-travel. Seasonal soil moisture changes cause automatic gate travel limits to drift out of calibration by spring, leading to gate stalling or impact with stops. The motor isn’t failing — the ground moved, and the control board needs reprogramming after structural correction.
- Broken or seized hinges on original 1960s–1980s gates. Union City’s housing stock is largely 1960s–1980s suburban tract development, with detached single-family homes common in the Decoto and Alvarado districts featuring original ornamental wrought-iron driveway and side-yard gates now 40–60 years old. These aging gates routinely show rust-through at welds, sagging hinges, and posts that have slowly migrated out of plumb as the underlying bay-fill soils have shifted over decades.

Here’s what gate repair costs in Union City’s market, based on jobs we’ve completed in the 94587 ZIP:
| Service | Typical Range in Union City |
|---|---|

Post reset costs run higher in Union City than in inland East Bay cities because of the footing depth required — 36 inches minimum in Alvarado and Decoto clay, versus 24 inches in stable soil. Salt corrosion also means we often find secondary weld damage once we start disassembling, which we quote before proceeding. Every estimate is free and itemized.

FAQs — Gate Repair in Union City
The expansive adobe clay soils beneath Alvarado’s flatland neighborhoods swell when saturated by winter rains and contract during dry months, exerting lateral pressure on posts set in shallow footings. Original 1970s construction typically used 18-inch footings that are no match for this movement; we reset to 36 inches minimum. Call (831) 218-8355 — we’ll check your post depth and give you a free estimate for permanent correction.
Salt-laden marine air off San Francisco Bay accelerates rust on uncoated steel and iron hardware significantly faster than in inland East Bay cities, attacking welds, hinges, and bottom rails first. We treat this with in-house weld repair, galvanized replacement hardware, and protective coating application. Call (831) 218-8355 for rust assessment — estimates are free.
Sometimes, if the post is plumb and the hinge points are structurally sound — we can adjust or replace hinges, redistribute gate weight, or trim a binding leaf. In Union City, though, sagging usually indicates post movement from clay soil heave, and re-hinging without resetting the post wastes your money. Kevin will check post plumb first and tell you honestly which approach applies. Call (831) 218-8355 for an on-site evaluation.
We repair and stock parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule — nine brands, covering the vast majority of automatic gates in Union City residential and commercial use. Most opener repairs are completed same-day with parts from our truck. Call (831) 218-8355 with your model number for confirmation.
Often yes — if the frame is structurally sound and the iron is thick-gauge original material, weld repair, post resetting, and hardware replacement can restore function for years at a fraction of replacement cost. We evaluate weld integrity, metal thickness, and post condition honestly; if replacement makes more sense, we’ll say so. Call (831) 218-8355 for Kevin’s assessment — estimates are free, and we don’t sell gates people don’t need.
