We’ve been driving out to Union City from our San Jose shop for more than four decades. We know the Alvarado ranches, the Decoto tract homes, and the newer townhome clusters near the BART station. The marine fog here is different from inland East Bay cities. It carries salt. It sits low across the flatlands. And it ruins gate hardware faster than most homeowners expect. We also know the bay mud clay beneath Union City’s streets, how it swells in January and shrinks by August, tilting posts and throwing automated gates out of alignment on a schedule you can practically set your watch by. That’s why our Gate Repair team stocks corrosion-resistant hardware and carries concrete pier equipment on every truck. We don’t make two trips.
Why Ironworks Gate Co. of San Jose Is Union City’s Preferred Gate Repair Company
Union City homeowners call us because we’ve been here long enough to understand what actually fails and why. Rick Almendarez founded Ironworks Gate Co. in 1984, and we’ve spent 42 years building a reputation on doing the job once and standing behind it. Our technicians are background-checked, uniformed, and trained on nine automation brands so the correct part is on the truck when we arrive.
We recently repaired a heavy-duty sliding gate on a rural property off Alvarado Boulevard where the original FAAC operator had failed due to salt corrosion from the marine layer, and the post had shifted 2 inches out of plumb because of the clay soil. We replaced the operator with a new LiftMaster Pneumatic slider, re-set the post in a concrete pier extending below the seasonal moisture line, and re-aligned the gate tracks - all in one trip, as promised.
Our 90-Day Done Right Promise applies to every Union City job. No paperwork. No arguing. If it’s not right, we come back and make it right. That’s the Keystone Standard, and it’s written on every invoice.
A live person answers our phones 24 hours a day, 7 days a week. Not a voicemail tree. Not an answering service. If your gate is stuck at 10 p.m. on a Sunday, you’ll talk to someone who can dispatch a technician.
Our Gate Repair Services in Union City
Hinge Repair
Union City’s salt-laden marine fog attacks hinges from the outside while bay mud clay shifts the gate frame from the inside. The result is seized, corroded hinges on gates that no longer swing true. We replace standard hinges with marine-grade, zinc-plated hardware rated for coastal exposure, and we re-hang the gate to account for any post shift. A typical hinge repair in Union City runs $180-$320.
Post Repair
This is the service we perform most often in Union City’s older neighborhoods. The expansive clay soils around Alvarado and Decoto Road swell with winter rains and contract in summer drought, gradually tilting posts out of plumb. A post that was perfectly vertical in October may lean two degrees by March. We excavate to stable soil, set a new concrete pier below the seasonal moisture line, and re-plumb the post with laser alignment. Post repair in Union City typically costs $350-$650 depending on depth and access. For gates with automated openers, we re-calibrate limit switches and safety sensors before we leave.
Weld Repair
The 1960s-1980s wrought iron and tubular steel gates common across Union City’s ranch-style tracts were built to last, but decades of salt corrosion have thinned pickets, weakened scrollwork, and cracked welds at stress points. Our mobile welding rig repairs these fractures in place, matching the original fabrication style so the repair disappears into the gate’s design. We also apply rust-inhibiting primer and touch-up paint to protect the fresh weld. Most weld repairs in Union City fall between $220-$450.
Gate Realignment
Because Union City’s soil shift is seasonal and predictable, realignment is rarely a one-time fix. We approach it as a system: we check post plumb, track level, hinge wear, and operator calibration together. A gate that drags in spring may need track adjustment, a hinge bushing, and sensor recalibration - not just a quick tweak. Our realignment service in Union City runs $240-$480 and includes a written assessment of whether post stabilization is needed to prevent repeat problems.
Rust Treatment
For gates that haven’t failed yet but are heading there fast, we offer full rust treatment: wire brush and grind to bare metal, phosphoric acid conversion coating, zinc-rich primer, and two coats of industrial enamel. In Union City’s marine environment, this extends gate life by years. Rust treatment typically costs $280-$520 depending on gate size and corrosion severity.
Lock Repair
Corroded lock mechanisms are a constant in 94587. We replace mortise locks, deadbolts, and magnetic locks with marine-grade equivalents, and we can rekey to match existing house keys.

For Union City customers, this means we stock common FAAC and Linear operator parts on our trucks, and we can reprogram BFT and Viking control boards on-site. Most automation repairs are completed same-day because the correct component is already in the van, not on a warehouse shelf two counties away.
Common Gate Repair Problems We See in Union City Homes
- Salt corrosion from the marine layer. The fog rolling off San Francisco Bay carries enough salt to rust standard hinges and latches within months of installation. We see this even on properties two miles inland, because Union City’s flat terrain offers no topographic barrier.
- Seasonal post tilting from bay mud clay. The soil beneath Alvarado and Decoto swells in winter and shrinks in summer, tilting posts out of plumb and causing gates to bind. Automated sensors fall out of alignment every spring and fall like clockwork.
- HOA gate operator failures near the BART station. Newer condominium complexes require proprietary reprogramming after power outages. Boards need vendors who understand these protocols and can document work for property managers.
- Aging wrought iron gates in original 1960s-1980s tracts. Many Union City homes still have their original ornamental gates, now 40-60 years old. The metal is fatigued, welds are cracked, and corrosion has thinned structural members. These gates need craft repair, not replacement.

FAQs - Gate Repair in Union City
The salt-laden marine fog rolling off San Francisco Bay accelerates corrosion on standard steel and iron hardware, even miles inland, because Union City’s flat terrain traps the moisture low to the ground. We replace failed hinges with zinc-plated, marine-grade hardware rated for coastal exposure, which lasts years instead of months. Call (866) 977-5773 for a free hinge inspection and exact quote.
We recommend sensor calibration every spring and fall, because the bay mud clay beneath your gate post swells with winter rains and shrinks in summer, tilting posts and throwing sensors out of alignment on a predictable seasonal cycle. Our $89 seasonal tune-up includes full sensor alignment, safety reverse testing, and hardware inspection. Call to book before the next season shift.
Probably not. In Union City, post shift from saturated clay soil is the most common cause of post-rain binding, not motor failure. The gate frame twists slightly, the track goes out of level, and the operator’s safety sensors trigger a stop. We diagnose the root cause on-site and can usually free the gate and restore operation without replacing the motor. Call (866) 977-5773 for same-day service.
Yes. We understand the board-approved repair protocols and proprietary operator programming required by HOA-managed communities near the Union City BART station. We document all work for property managers and can coordinate access with residents. Our technicians are trained on the specialized control boards these properties use.
Almost always. The wrought iron and tubular steel gates installed across Union City’s 1960s-1980s tracts were built with thick material that can withstand decades of fatigue if the corrosion is addressed. We grind to sound metal, repair cracked welds with our mobile rig, and apply protective coatings that stop further decay. Replacement is rarely necessary. Call for a free assessment - we’ll tell you honestly what can be saved.
