Trusted Gate Repair for San Francisco Homeowners
Gate repair in San Francisco typically costs $180–$650 depending on the problem, and most repairs are completed in a single visit when you work with a specialist who stocks parts and welds on-site. At Liberty Gate Repair San Francisco, we’ve spent over 31 years working on gates exclusively — not as a sideline to general contracting, but as our sole focus since day one. Owner and Lead Technician Steven Lee diagnoses it, Steven fixes it, which means the person answering your call is often the same person swinging the wrench at your property.

San Francisco’s steep hills, salt-laden fog, and century-old masonry walls create gate problems you won’t find in inland markets. We’ve replaced rusted hinges in the Outer Sunset that corroded from Pacific moisture, realigned sagging gates in Noe Valley where shifting foundations threw everything off square, and welded broken frames in the Mission where decades of Mission District traffic took their toll. Our 613 verified reviews averaging 4.9 stars reflect what happens when a specialist shows up prepared — with the right parts, the right brand knowledge, and the welding capability to finish the job without scheduling a second trip. Call (628) 261-6223 for a free estimate anywhere in the city.
What Our Gate Repair Service Includes
Hinge Repair
Gate hinges bear every pound of your gate’s weight through thousands of open-close cycles, and in San Francisco’s coastal climate, they’re often the first component to fail. When hinges seize, sag, or pull away from their mountings, your gate drags, binds, or stops latching properly — sometimes taking the post with it. We assess whether the hinge itself is worn, the mounting bolts have wallowed out their holes, or the underlying post has rotted or cracked, then we repair or replace with hardware rated for your gate’s actual weight and wind load.
Post Repair
A leaning or rotted gate post doesn’t just look bad — it transfers stress to every other component and eventually ruins the gate itself. In San Francisco’s older neighborhoods, we regularly find original redwood or cedar posts that have reached their end of life, or steel posts that have rusted through at the concrete line from decades of soil contact and fog-driven moisture. We evaluate whether a post can be sistered and re-anchored or needs full replacement, and we pour new concrete footings to code depth with proper drainage so the problem doesn’t repeat in three years.
Weld Repair
Cracked welds on iron, steel, or aluminum gates aren’t cosmetic — they’re structural failures that propagate until the gate collapses or someone gets hurt. Our in-house welding capability means Steven Lee can grind out the crack, prep the metal, lay a proper penetrating weld, and finish-match the surface right there in your driveway or commercial lot. We’ve welded everything from ornate Victorian ironwork in Pacific Heights to heavy-duty commercial slide gates in the Bayview, and because we don’t farm out welding to a third party, there’s no delay and no markup.
Gate Realignment
When a gate that used to swing freely now scrapes the ground or won’t meet its latch, the cause is rarely “just” one thing — it’s the accumulated effect of hinge wear, post settlement, ground shifting, or frame distortion. San Francisco’s hills and fill soils make this especially common; we’ve realigned gates in the Marina where liquefaction-prone soils shifted after winter storms, and in Potrero Hill where decades of hillside creep slowly torqued the frame. We diagnose the root cause, correct it, and then adjust the gate geometry so it tracks true again.
Lock Repair
Gate locks and latches fail from corrosion, forced entry attempts, or simple mechanical wear — and a gate that won’t secure is a gate that isn’t doing its job. We repair and replace mechanical deadbolts, magnetic locks, electric strikes, and keypad-integrated latching systems, matching the hardware to your actual security needs rather than overselling. If your lock is part of an access control system from DoorKing, Elite, or another brand we service, we ensure the mechanical and electronic components communicate properly after repair.
Rust Treatment
San Francisco’s marine layer delivers moisture that condenses on metal surfaces morning after morning, accelerating rust far beyond inland rates. Surface rust on iron or steel gates isn’t just unsightly — once it pits the metal, structural integrity degrades quickly, especially at weld points and hardware attachments. We grind or media-blast to bare metal, treat with rust-converting primer, and apply industrial-grade finishes designed for coastal exposure, extending the serviceable life of gates that would otherwise need replacement in a few short years.

Brands We Service for Gate Repair
We’ve serviced hundreds of LiftMaster gate operators and stock their OEM replacement parts, from residential swing-garage combos in the Richmond to commercial slide-gate systems in SOMA. FAAC and BFT — both Italian manufacturers with strong commercial presence in the Bay Area — require specific hydraulic troubleshooting knowledge that general repair crews often lack; we’ve rebuilt FAAC hydraulic operators and recalibrated BFT control boards in the field. Linear and Viking operators appear frequently on multi-family and commercial properties throughout the city, and we carry common Linear actuator assemblies and Viking control modules to avoid ordering delays.
Ghost Controls residential systems have grown popular for their DIY-friendly design, but when the control board fails or the actuator seizes, owners need a technician who understands their proprietary programming sequence — we do. DoorKing and Elite access systems gate communities and commercial lots across San Francisco, and we maintain the loop detectors, telephone entry systems, and barrier arm operators that integrate with them. Mighty Mule budget-friendly openers often outlast their original hardware; we’ve upgraded dozens with heavier-duty arms and reinforced mounting brackets. Whether you have one of these nine brands or any other make, we can help — and we’ll tell you honestly if a system has reached replacement age rather than billing you for patchwork.
Signs You Need Gate Repair Right Now
- The gate drags or scrapes the ground. This usually means hinge wear, post settlement, or frame sag — and every day you force it open, you’re multiplying the damage. In San Francisco’s hilly terrain, a dragging gate can also indicate soil movement beneath the footing that won’t fix itself.
- You hear grinding, squealing, or clicking from the operator. These sounds are the motor or gearbox telling you it’s working harder than designed, often because the gate mechanics are binding. Continuing to operate it burns out the operator — turning a $200 mechanical repair into a $1,200+ motor replacement.
- The remote works intermittently or only from certain angles. Before assuming it’s just the remote battery, check whether the gate is moving sluggishly; a motor drawing excessive amperage can trip internal overloads that mimic remote failure. We diagnose the difference in one visit.
- Visible rust, cracks, or separation at welds or joints. San Francisco’s fog accelerates corrosion, and cracked welds propagate fast under cyclic loading. What photographs as a “small crack” in March can be a complete break by October — especially on wind-exposed hillside properties in Twin Peaks or Bernal Heights.
- The gate won’t latch or lock securely. A gate that doesn’t fully close defeats its purpose, and the gap often widens gradually as underlying mechanical problems progress. We’ve responded to calls in the Sunset where a misaligned latch allowed the gate to blow open in evening fog winds — simple to prevent, expensive to discover the hard way.
Our Gate Repair Process — Step by Step
- 1
Describe your problem when you call (628) 261-6223. We’ll ask about your gate type, brand, symptoms, and how long the problem has existed. This lets Steven Lee arrive with the right parts and tools rather than making a diagnostic trip followed by a repair trip.
- 2
On-site inspection and root-cause diagnosis. We don’t quote from a flat-rate menu — we examine the gate, operator, access hardware, and structural supports to identify what’s actually wrong versus what merely appears wrong. A “dead operator” often traces to a $40 limit switch, not a $900 replacement.
- 3
Upfront written estimate before any work begins. You’ll know the exact scope and cost, with no hidden charges for “additional labor” or “unexpected complications.” If we discover something unforeseen during repair, we stop and discuss it — we don’t bill surprises.
- 4
Repair using in-house parts and welding capability. Most repairs are completed in one visit because we stock components for the nine major brands we service and weld structural repairs on-site. No waiting for a subcontractor, no return appointment two weeks out.
- 5
Operational testing and documentation. We cycle the gate through its full range, test all safety features (photo eyes, edge sensors, auto-reverse), verify remote and keypad function, and provide documentation of work performed for your records and any warranty claims.
How Much Does Gate Repair Cost in San Francisco?
A typical hinge repair or adjustment in San Francisco runs $180–$280, while post repair or replacement ranges from $350–$650 depending on whether we’re resetting an existing post or pouring new concrete for a full replacement. Weld repair on iron or steel gates generally falls between $250–$450 for crack remediation and finish work, and gate realignment — which often combines hinge work, post shimming, and frame adjustment — typically costs $200–$400. Lock and latch repair ranges from $150–$300 for mechanical hardware, or $280–$500 when integrated with electronic access control systems. Rust treatment and refinishing starts around $300 for surface preparation and coating on a standard residential gate, scaling up for extensive pitting or ornate ironwork requiring detailed masking.

Several factors move these ranges: gate material (wrought iron and aluminum require different welding approaches than steel), access difficulty (steep San Francisco lots or tight commercial loading docks add time), and whether the underlying problem has been neglected long enough to damage secondary components. The best way to avoid overpaying is addressing symptoms early — a grinding hinge fixed at $220 prevents the $600+ cascade of bent frame, burned-out operator, and post damage. Every estimate we provide is free, detailed, and no-obligation; call (628) 261-6223 to schedule yours.
