We know the Decoto district’s rusted 1960s wrought-iron gates and the 1980s condo slide gates off Alvarado-Niles Road better than any out-of-town shop. Call (669) 800-5686 and you’ll get a live person, a real arrival window, and a written price before any work starts.

Portcullis Gate Repair San Jose is an independently owned Kingswell company, which means every job in Union City carries four written promises: a price before we touch a bolt, a real arrival window, a clean job site, and a written guarantee on the repair. Dean Prescott, who runs our crew, has spent 17 years fixing the specific failures that Union City’s bay air creates: corroded hinge posts, obsolete control boards, and loop detectors buried in cracked asphalt. When a Union City homeowner calls about a sagging iron gate, we already know the likely culprit is the hinge post, not the panel itself.

Styles & brands we work with





Iron Gate Repair in Union City
Iron Gate Repair in Union City is the core of what we do, and around here the job usually starts at the hinge post, not the gate leaf. Decades of salty marine air off San Francisco Bay eat through the mild steel at the base of original 1960s ornamental gates. The panel still looks fine, but the post rots from the inside, the gate sags, the hinge pins seize, and the whole thing drags a groove into the concrete. A full iron gate repair in Union City, including cutting out the rotted post base, welding a new footing, and swapping in stainless hinge pins, typically runs $350 – $650 parts and labor.
Hinge and Post Replacement
When a gate won’t swing, most people assume the panel is the problem. In Union City’s older tracts, it’s almost always the hinge post. We cut out the corroded section, weld in a new steel footing, and set the gate back to plumb. If the panel itself is still sound, you just saved two thousand dollars versus replacing the whole gate.
Weld and Rust Repair
Bay air doesn’t need a storm to do damage. It works every day, all year. We grind back the rust scale, weld in new steel where the bottom rail has thinned to nothing, and treat the seam so moisture can’t get back in. For gates that are structurally intact but cosmetically rough, this repair usually runs $200 – $400 and adds years of service.
Sliding Gate Repair in Union City
Sliding Gate Repair in Union City most often means one of two things: a 1980s condo complex gate whose control board has finally died, or a residential slide gate whose rollers have worn flat on a misaligned track. The old condo operators built into the hillside communities around Mission Boulevard used boards that nobody manufactures anymore. When they fail, the gate stops mid-travel and stays there. We stock retrofit boards and modern safety photocell kits, so the fix is measured in hours, not weeks. Expect $300 – $700 for a board and photocell retrofit on a Union City slide gate.
Track and Roller Repair
A slide gate that shudders or grinds as it moves usually has flattened steel rollers cutting into a worn track. We replace the roller assembly, clean and realign the track, and adjust the operator’s torque so it stops fighting itself. This is a $250 – $450 job in Union City when caught before the track itself is destroyed.
Obsolete Control Board Retrofit
If your condo or apartment gate runs a control board from the 1980s or early 1990s, stop patching it. Those boards fail intermittently, which means the gate works for a week and then dies on a Tuesday morning. A modern retrofit board with safety photocells costs $500 – $900 installed in Union City and eliminates the single point of failure that’s been haunting your residents.
Trusted Brands We Service in Union City
Our techs train on nine major gate-operator brands, and we keep common parts for FAAC, BFT, Linear, and Viking systems on the truck when we run calls in Union City. That means a failed FAAC actuator on a Decoto driveway gate doesn’t sit open for three days waiting on a part from a warehouse. We know the specific failure points on each brand. Linear’s older swing arms strip drive gears. BFT boards develop cold solder joints. When you call us to Union City, the tech who shows up already knows your system.
Common Gate Repair Problems We See in Union City Homes
- Rusted-through hinge posts on 1960s ornamental iron gates. The Decoto district has rows of custom wrought-iron gates whose posts are corroded from the inside by salty bay air. The gate sags, the hinges seize, and the panel gets blamed for a post problem.
- Obsolete control boards in 1980s gated condo complexes. Slide gates built during the bay-area condo boom use boards that are no longer manufactured. When they fail intermittently, the gate sticks mid-travel and residents can’t get in or out.
- Loop detectors failing in cracked asphalt. Seasonal temperature swings crack Union City’s asphalt driveways, and the buried detector loop stops sensing vehicles. The gate closes on a car or refuses to open for a resident, and the fix is the loop, not the operator.
- Wooden gates swelling from winter storms. The same marine air that rusts iron also swells wooden gate frames. A gate that scraped by in October jams solid after a wet December, and the fix is usually hinge adjustment plus frame planing, not a new gate.

FAQs About Gate Repair in Union City
Because Decoto sits low and close to the bay, and the original 1960s wrought-iron gates there were built with mild steel hinge posts that had no corrosion protection. Fremont’s inland areas get less salt exposure. In Decoto, the posts rust from the inside, the hinges seize, and the gate stops swinging. The fix is cutting out the rotted post section and welding in new steel, not lubricating the hinge and hoping. Call (669) 800-5686 and we’ll tell you honestly whether your post is worth repairing or needs replacing.
Yes. We do this regularly on Union City’s gated condo properties. The original operator’s control board is obsolete, but the motor and track are often still sound. We install a modern retrofit board that supports current safety photocells and edge sensors. The cost runs $500 – $900 installed. Call (669) 800-5686 and we’ll walk the property and give you a written quote for the full retrofit.
We fix the hinge post, not the gate panel. In most Union City homes, the panel is still straight and the problem is the post has rotted at the base, letting the gate drop. We cut out the corroded section, weld in a new steel footing, reset the gate to plumb, and install stainless hinge pins so the repair outlasts the original steel. A full hinge post and realignment runs $350 – $650. Call (669) 800-5686 for an exact quote, free.
A loop detector is a wire buried under your driveway that senses the metal of a vehicle and tells the gate operator to hold open or reverse. Union City’s cracked asphalt from seasonal temperature swings breaks these loops. When the loop fails, the gate closes on a car or won’t open for a resident. The fix is cutting a new loop into the asphalt and wiring it to the operator, usually $300 – $500. Call (669) 800-5686 and we’ll test your loop before touching your operator.
If the bottom rail has rusted through but the hinge posts and the rest of the frame are sound, repair usually wins. $200 – $400 gets you weld repair and rust treatment versus $2,000+ for a new custom iron gate. But if the hinge posts are also rotted and the top rail is thinning, replacement starts to make real sense. We’ll give you both numbers in writing and let you decide. Call (669) 800-5686 for a free estimate that covers both options.
