Fast, Reliable Gate Repair Across San Francisco
Gate repair in San Francisco typically runs $180–$650 depending on the problem, and most calls are completed same day. We’re Granite Gate Repair California, and our Gate Repair team makes the drive up from San Jose to handle the corrosion, settlement, and tight-space challenges that define gate work in this city. Louis Barrera and the Granite Gate team have spent 14 years focused exclusively on gates — not garage doors, not fencing, not handyman work — and that specialization matters when you’re dealing with 120-year-old iron hardware on a 25-foot lot with no alley access. Call (888) 416-1369 for a free estimate.

When you hire Granite Gate Repair California, you’re getting direct accountability from someone who can actually repair your gate, not just dispatch a subcontractor.
Our Gate Repair Services in San Francisco
Hinge Repair
San Francisco’s marine fog accelerates corrosion on iron gate hardware from the inside of mounting brackets outward, a failure mode far less common in drier inland cities like Walnut Creek. We see this constantly on the decorative pedestrian gates of Victorian and Edwardian rowhouses — hinges that look fine externally but have seized internally from salt-saturated moisture. We recently serviced a 1905 Edwardian rowhouse at 22nd and Guerrero, where the wrought-iron pedestrian gate’s top hinge had rusted through internally from decades of fog exposure. We replaced the hinge with a stainless steel LiftMaster unit and applied a marine-grade rust inhibitor to the remaining hardware. Typical hinge repair in San Francisco runs $180–$320.
Post Repair
On the bay-fill blocks of SoMa (94103) and Dogpatch (94107), technicians routinely find that a gate “won’t latch” not because of a broken latch but because the post has drifted an inch or more out of plumb due to differential soil settlement — a diagnosis that sends the repair toward re-setting the post rather than replacing hardware, a call that almost never comes up in stable-soil cities across the bay. Wooden gate posts in fog-belt exposures near the bay show rot concentrated at the base where moisture wicks up through concrete footings. We excavate, treat the rot, and reset with proper drainage. Post repair in San Francisco typically costs $280–$550.
Weld Repair
Most gate companies outsource welding. We don’t. Our in-house fabrication shop means we can repair cracked iron scrollwork on ornamental gates in Chinatown’s historic corridors or reinforce sagging frames on commercial roll-down security gates in SoMa without waiting for a third-party vendor. Louis handles structural welding personally on complex jobs. Weld repair in San Francisco generally runs $200–$450 depending on material and access.
Gate Realignment
Seismic micro-settling on bay-fill ground routinely racks wooden gate frames and shifts masonry posts out of plumb. Misalignment is the dominant recurring failure mode in San Francisco alongside rust. We measure, shim, and re-hang to true vertical — often saving a gate that appeared to need full replacement. Realignment work in San Francisco typically costs $220–$380.
Lock Repair
100-plus-year-old wrought-iron gates often have worn latch mechanisms that fail to catch, requiring custom fabrication when off-the-shelf hardware won’t mate with century-old strike plates. We machine or weld custom solutions in-house. Lock and latch repair in San Francisco runs $160–$290.
Rust Treatment
San Francisco’s marine layer delivers persistent salt-saturated moisture for the bulk of the year without the diluting effect of heavy rainfall, meaning iron hinges, strike plates, and latch mechanisms corrode from the inside of their mounting hardware outward — a subtler and faster-acting process than the freeze-thaw or monsoon damage seen in other climates. We strip, treat, and coat with marine-grade inhibitors that actually hold up in this environment. Rust treatment in San Francisco typically costs $150–$280 for pedestrian gates, $280–$450 for larger driveway systems.

Trusted Brands We Service in San Francisco
Your brand, our specialty. We carry field stock and direct supplier relationships for FAAC, BFT, Linear, and Viking systems — plus five additional major brands — which means San Francisco customers aren’t waiting a week for a parts order from out of state. A property manager in the 94111 ZIP with a Viking slide-gate operator can get same-day motor diagnosis because we travel with common Viking control boards and limit switches. That parts-on-hand approach is how we keep commercial security gates in Chinatown and SoMa back in motion fast.
Common Gate Repair Problems We See in San Francisco Homes
- Rust-induced hinge seizure: Salt-laden fog causes iron hinges to corrode internally, leading to binding and gate sag. The hinge looks intact until you try to swing the gate and feel the grind.
- Post drift from soil settlement: On bay-fill neighborhoods like SoMa, gradual soil shifting pushes posts out of plumb, causing misalignment that worsens seasonally.
- Latch failure due to age: 100-plus-year-old wrought-iron gates often have worn latch mechanisms that fail to catch, requiring custom fabrication when modern hardware won’t interface with original strike plates.
- Rot at wooden post bases: Fog-belt moisture wicks up through concrete footings, concentrating decay where the post meets the ground — invisible until the gate leans.

FAQs — Gate Repair in San Francisco
Because oil sits on the exterior surface while San Francisco’s salt-laden marine fog penetrates the internal cavity of the hinge bracket, corroding from the inside out. Regular oiling helps but doesn’t seal the internal void where moisture concentrates. We replace with stainless steel hardware and apply vapor-phase inhibitors that reach where oil can’t. Call (888) 416-1369 for an inspection — estimates are free.
In San Francisco, it’s rarely the rain itself; it’s the soil shift that follows moisture infiltration in bay-fill areas. Your post has likely drifted out of plumb, moving the latch and strike plate out of alignment. We measure post verticality before replacing any hardware — a distinction that saves you from buying a latch you don’t need. Call (888) 416-1369 and we’ll diagnose it properly.
Yes. We’ve repaired 100–120-year-old wrought-iron pedestrian gates in Victorian and Edwardian corridors throughout the 94114 and 94115 ZIPs. We preserve original scrollwork where possible and fabricate matching elements in-house when replacement is unavoidable. Louis Barrera handles welding on historic fabrications personally.
We bring compact equipment and break down work into portable components. For welding, we sometimes pull the gate to our San Jose shop rather than attempt outdoor fabrication in a 6-foot side passage. We plan this into our scheduling so you’re not stuck with a missing gate overnight.
Yes. We install modern receiver kits on existing FAAC, Linear, and Viking operators that convert fixed-code remotes to rolling-code encryption. Most upgrades take 90 minutes and work with your current motor if it’s in good mechanical condition. Rolling-code retrofit in San Francisco typically runs $240–$380 including remotes. Call (888) 416-1369 to check compatibility with your specific opener model.
