Fast, Reliable Gate Repair Across Union City
Gate repair in Union City usually lands between $180 and $340 for a service call when a hinge has seized or a gate has dropped off its plane, and most jobs are done same-day. We’re Gatewood Fence & Gate, and we’ve been fixing gates since 2001. Hal Gatewood runs this shop with his own name on the door, and he’ll tell you straight what a repair ought to cost before we ever touch a wrench. If your gate is dragging, sagging, or refusing to open, call (877) 610-2993 and you’ll speak to a person, not a machine.
Union City is its own animal when it comes to gate work. The salt air off the bay, the tract homes from the 70s and 80s, the industrial gates along Dyer Street and Whipple Road that cycle a hundred times a day – all of it means the gate failures we see here look different than what our crew encounters ten miles east. We know the neighborhoods here, and we know what this climate does to gate hardware.
Key Takeaways
- Most Union City gate repairs run $180-$340, with full hinge or post replacements running higher depending on the gate’s size and material.
- Union City’s salt-laden bay air corrodes gate hinges and operator gearboxes years faster than in Fremont or Hayward.
- We repair first, replace only when the repair would cost more than a new gate would save.
- Call (877) 610-2993 and you’ll talk to a live person, 24/7. Estimates are free.
Why Gatewood Fence & Gate Is Union City’s Preferred Gate Repair Company
We’re the company Union City calls when a gate has been patched twice by somebody else and it’s still leaning. Folks here have learned to check whether the person who answers the phone actually knows gates. Hal Gatewood does. He’s been owner-operator since 2001, and he’s picked up parts at the same supply houses along the East Bay for over two decades. He tells you what a repair should cost, writes it down, and sticks to it. No big-box price at the door, no add-on line items.
Every job we do in Union City carries the 90-Day Done Right Promise – it’s stamped on the invoice, and if the repair doesn’t hold, one call brings us back. No runaround. We also answer the phone live, 24/7. Not a voicemail, not a third-party call center. When a warehouse operator on Whipple Road has a slide gate stuck open at 6 a.m., they call and a person answers. That matters in a city with this much light-industrial traffic.
Our crew serves Union City directly. We don’t outsource to a chain of subcontractors; the person who shows up is background-checked, uniformed, and works under Hal’s name. That’s the set-up that makes sense for the homeowners and businesses out here.
Our Gate Repair Services in Union City
Most Union City gate failures we walk up to are one of four things. Here’s what those look like in practice.
Weld & Rust Repair
The bay air rolling off the Don Edwards San Francisco Bay National Wildlife Refuge sits against Union City’s western edge, and that’s where the worst gate corrosion happens. We see rusted-out hinges, seized latches, and swing gate frames with rust-through at the bottom rail. Our Gate Repair crew welds on site, on your driveway, not at some off-site shop. We cut out the rusted section, weld in new steel, and coat it so the salt doesn’t eat it again for a while.
On gate operators along the industrial corridor near Union City Blvd and Dyer Street, the failure is often the same problem in a different part: galvanic corrosion inside the gearbox. We open the unit, inspect the drive gears, and if the damage is isolated, we replace the gear set and reseal it rather than quoting you a whole new operator.

Hinge & Post Repair
In Decoto and Alvarado, where most homes date from the 1970s through the early 1990s, the original gate posts are often thin-gauge steel set straight into the soil. Thirty or forty years of bay-influenced humidity rots them from the ground line down. A gate that sags isn’t usually a hinge problem – it’s a post that’s given up. That’s where we start: remove the old post footing, set a corrosion-resistant replacement, and weld new heavy-duty hinges before re-hanging the gate. Fix the panel without fixing the post and you’ll be paying for the same job twice.

Automatic Gate Repair
Automatic gate openers in Union City suffer from the same salt air, but the failure route is different. Electric slide gates along Dyer Street and Whipple Road often run high daily cycle counts, and the combination of constant use and corrosive marine air strips the drive gears in five to seven years. In a drier inland market like Livermore the same operator might run ten to twelve years. We rebuild gear sets, replace worn limit switches, and retrofitting operators that have lost their gears. When we’re done, the gate runs quiet again.

Gate Realignment
When a swing gate drags on the concrete or a slide gate binds mid-track, Union City homeowners usually call us expecting a new gate. Plenty of times, the gate itself is fine. The hinges have worn, or the gate has shifted on its posts, or the track has settled after years of wet winters. We set the gate back on its plane, re-shim the hinges, and check that the operator’s force settings still fall within safety limits. That’s half the battle: older operators push too hard because someone cranked the force up rather than fixing the alignment. We fix the alignment.

Trusted Brands We Service in Union City
We service and repair nine major gate operator brands, and the ones Union City customers call about most are FAAC, BFT, Linear, and Viking. Those names show up again and again on the residential swing gates in the 1970s tracts and the commercial slide gates off Whipple Road. We stock common control boards, gear sets, and remote receivers for these brands locally, which means we’re not waiting on a distribution warehouse in another state to ship a part across the country. If your FAAC is stuck and you’re in Union City, we can usually have it running the same day.
Common Gate Repair Problems We See in Union City Homes
- Galvanic corrosion on hinge posts. The salt air off the bay settles into the soil around gate posts in Decoto and Alvarado, and steel posts rot at ground level. Within 30 to 40 years, the post fails outright and the gate leans hard. This is the single most common swing gate failure we see in Union City.
- Stripped or seized slide gate drive gears. Along the Dyer Street and Whipple Road corridors, electric slide gates run high cycle counts and sit in marine air all year. The gear teeth wear away or seize up in five to seven years, well before the operator’s rated life.
- Obsolete control boards without entrapment protection. We still find pre-UL 325 gate operators on older Union City industrial properties – the kind with no photo eyes, no safety edges, and no reversing mechanism when the gate hits an obstruction. These can be retrofitted to current safety standards, and if they’re too far gone, we’ll tell you plainly.
- Gate hinges frozen from rust. Residential gates on the west side of Union City, close to the marshlands, often have hinges that have rusted solid. The motor tries to move the gate and the hinges resist until the motor burns out. Lubricating a rusted hinge buys a week. Replacing it with sealed-bearing corrosion-resistant hardware is the repair that lasts.
Pricing for Gate Repair in Union City, CA
Here’s what gate repair actually costs in Union City, no phone-price bait. A basic service call to diagnose a gate problem runs about $90-$120. A hinge replacement on a standard tubular steel swing gate typically falls between $180 and $280, including labor and materials. A post replacement, where we dig out the old footing and set a new corrosion-resistant post, usually runs $350-$600 depending on gate size and access. Gear sets for slide gate operators land in the $250-$450 range installed. Full automatic gate repair jobs that combine motor work, hinge work, and realignment often total $500-$900. Every price gets quoted and agreed before we start – written, not verbal.

FAQs - Gate Repair in Union City
Union City sits closer to the bay’s saltwater edge than most of Fremont’s eastern hillside neighborhoods or Hayward’s inland zones. The Don Edwards San Francisco Bay National Wildlife Refuge forms Union City’s western boundary, and the marine air that moves off the bay carries fine salt particles that settle on exposed metal. Untreated iron and steel on gate hinges and posts sits in that salty film for months at a time, accelerating galvanic corrosion well beyond what drier air a few miles east would produce. Call (877) 610-2993 and we can replace those rusted hinges with sealed-bearing, corrosion-resistant hardware that holds up better here.
In many cases, an older Union City operator can be brought to UL 325 compliance by adding a safety photo eye, a reversing edge, and a force limiter, but no, not every old board can be saved. The deciding factor is the control board: if it predates modern entrapment protection inputs, the retrofit cost often approaches the cost of a new operator, and we’ll tell you so straight rather than selling you a patch. If the board supports the add-ons, we retrofit what we can. When replacement is the cheaper long-term answer, we say that too. Call (877) 610-2993 for a free assessment.
The answer in Union City is usually the post, not the hinge. Most Decoto and Alvarado tract homes still have their original gate posts from the 1970s through the 1990s, and those posts have been sitting in wet, salty soil for decades. When the post rots below grade, the gate leans and the hinges get blamed. We check the post first, because putting new hinges on a rotten post means you’ll be doing the job again in a year. Call (877) 610-2993 and we’ll tell you which one is actually failing.
If you’re on Dyer Street, Whipple Road, or anywhere in Union City’s industrial corridor, six years is about average for a slide gate drive gear. The operators in that area run high daily cycle counts – hundreds of open and close cycles a day on some warehouse gates – and the salt-laden air accelerates wear on gear teeth. We see gearboxes that fail in five to seven years here, where the same unit in a drier inland city would make ten or twelve. It’s not a bad brand; it’s a bad environment for untreated gears. We replace gear sets, reseal the housing, and recommend corrosion-resistant components that last longer. Call (877) 610-2993 for an exact quote on your site.
For Union City’s salt-influenced air, standard zinc-plated hinges fail fast. Galvanized steel is better, but the most durable option is stainless steel or sealed-bearing hinges rated for coastal environments. A stainless hinge post receiver bushing also keeps the post itself from becoming the sacrificial anode in the galvanic couple. These cost a bit more than the zinc-plated parts, but they’re far cheaper than replacing a post. Call (877) 610-2993 for a recommendation on your specific gate, not a generic upsell.
