Trusted Gate Parts & Welding for San Francisco Homeowners
Gate parts and welding in San Francisco typically costs $180–$850 depending on the repair, and most structural fixes can be completed in a single visit when parts are stocked and welding is done on-site. For homeowners from the Sunset District to Bernal Heights, that means no waiting days for a subcontractor or second appointment. Call Liberty Gate Repair San Francisco at (628) 261-6223 for a free estimate — we carry parts and weld on-site.
Over 31 years working on gates exclusively, we’ve learned that San Francisco’s coastal fog, steep hills, and salt air chew through gate hardware faster than inland climates. Hinges seize. Posts lean on sloped driveways. Rails crack where the wind funnels through gaps between buildings. Steven Lee, our owner and lead technician, has rebuilt gates in every neighborhood from the Marina to Bayview, and our 613 customers rated us 4.9 stars because we diagnose the real problem — not just the symptom — and fix it with parts and welding capability in our trucks.
We’re not general contractors who “also do gates.” Liberty Gate Repair was built around gates from day one. Steven diagnoses it, Steven fixes it. That owner-operator accountability means no passing you between crews or disappearing into a dispatch queue.
What Our Gate Parts & Welding Service Includes
Hinge Replacement
Gate hinges bear the full weight of your gate every time it opens or closes, and in San Francisco’s salty air, even galvanized steel corrodes within 5–7 years. When hinges bind, squeal, or let the gate sag, the motor strains, the frame twists, and eventually something more expensive breaks. We stock heavy-duty ball-bearing hinges, adjustable j-bolt hinges, and piano-style continuous hinges for wrought iron and aluminum gates, and we weld new hinge plates directly to the frame when the original mounting surface has eroded.
Post Replacement
A leaning or rotted gate post is a structural failure that won’t fix itself, especially on San Francisco’s hills where gravity works against you daily. We’ve replaced posts in Noe Valley where the original installer set wood directly in concrete (guaranteed rot), and in the Richmond where clay soil expansion pushed posts off-plumb. Steven Lee digs to proper depth — usually 36–48 inches for residential gates, deeper for cantilever commercial systems — sets the post in gravel for drainage, and welds the gate mount directly to a steel post for zero flex.
Rail Repair
Horizontal rails keep your gate square and support pickets or panels; when they bend or separate, the gate racks and jams in the track or against the jamb. In the Mission, we’ve repaired dozens of driveway gates where delivery trucks clipped the bottom rail, and in Pacific Heights, we’ve fixed ornamental iron where rust hollowed the rail from the inside out. We cut out damaged sections, sleeve or splice with matching material, and weld with 7018 rod for strength that matches or exceeds the original fabrication.
Custom Welding
Not every gate problem fits a catalog part. Custom welding covers broken scrollwork on historic Victorian-era gates in Haight-Ashbury, fabricated catch plates for non-standard latches, and reinforcement gussets for gates that have outlived their original engineering. Steven Lee MIG and TIG welds aluminum, steel, and wrought iron on-site, so a gate that would otherwise need shop removal and weeks of waiting gets fixed in hours. We match existing profiles and finishes so the repair disappears visually.
Gate Rollers
Sliding gate rollers live in the dirt, moisture, and debris of a ground track, making them the highest-wear component on any sliding system. In San Francisco’s Outer Sunset, where sand blows in from Ocean Beach, we’ve replaced rollers that were seized solid after three years. We stock V-groove, flat, and cantilever carriage rollers for brands from LiftMaster to FAAC, and when the roller bracket itself has cracked, we weld a new one rather than forcing a generic replacement that doesn’t fit.
Latch & Lock
A gate that doesn’t latch reliably is a gate you’ll stop using — or one that blows open in the wind and damages whatever it hits. We replace magnetic latches, deadbolts, electric strike locks, and pool-code-compliant self-latching hardware. In Twin Peaks, where wind gusts hit 40+ mph, we’ve upgraded latches to two-point locking systems and welded reinforced strike boxes that don’t flex under impact. If your access control system integrates with the latch, we wire it cleanly and test every function before leaving.

Brands We Service for Gate Parts & Welding
We’ve serviced hundreds of LiftMaster residential and commercial operators and stock their hinge kits, roller assemblies, and replacement arms. For FAAC and BFT — common in San Francisco’s newer multi-unit developments — we carry hydraulic fluid seals, control boards, and welding hardware for their heavy-duty swing and slide gate systems. Linear and Viking operators appear frequently in commercial properties along the Embarcadero and SOMA, and we keep their drive gears, limit switches, and mounting brackets on our trucks.
Ghost Controls and Mighty Mule dominate the DIY-installed residential market in neighborhoods like the Sunset and Parkside, and we’ve replaced more of their stripped nylon gears and bent actuator arms than we can count. DoorKing and Elite access control systems — prevalent in HOAs and gated communities from St. Francis Wood to Sea Cliff — require precise alignment that welding and parts replacement must respect; we measure, adjust, and test integration before calling any job complete. Whether you have one of these nine brands or any other make, we can help. Our home page outlines our full service scope across the Bay Area.
Signs You Need Gate Parts & Welding Right Now
- The gate drags or scrapes the ground. This usually means a sagging hinge, bent frame rail, or settling post — all fixable, but all progressive. Left alone, the motor overworks, the track wears unevenly, and the gate itself can torque beyond repair. We’ve seen $200 hinge replacements turn into $1,800 full-gate rebuilds in under a year.
- You hear grinding, popping, or metal-on-metal noise. Ball-bearing hinges don’t grind; rollers don’t pop. These sounds mean something has failed or is failing structurally. In the fog belt from the Richmond to the Sunset, corrosion accelerates this damage. Call before the noise becomes a jam.
- The gate won’t latch consistently. A latch that needs multiple tries or body-weight shoves indicates frame racking, post movement, or strike-plate wear. It’s also a security gap — and in San Francisco, an unlatched gate is an invitation. We weld reinforced strike boxes and realign frames to fix the root cause, not just the symptom.
- Visible rust, cracks, or separation at welds. Surface rust on ornamental iron is cosmetic; rust bubbling through paint at joints or cracks in weld beads is structural. The salt air in neighborhoods near the Presidio or Crissy Field destroys gates from the inside out. We grind to clean metal, weld repair or replace sections, and finish with rust-inhibiting primer.
- The motor runs but the gate barely moves. This often masquerades as an opener problem when it’s actually mechanical binding — seized rollers, twisted rails, or a post that has shifted on its footing. Steven Lee starts every diagnostic with manual operation: if the gate won’t move freely by hand, no motor replacement will fix it. Parts and welding will.
Our Gate Parts & Welding Process — Step by Step
- 1
Phone diagnosis and scheduling. When you call (628) 261-6223, we ask specific questions: gate type, brand if known, symptoms, and photos if you can text them. This lets Steven Lee load the right parts and welding gear before leaving, so we’re not making a “parts run” on your time.
- 2
On-site inspection and manual testing. Steven arrives, disconnects the opener, and tests the gate by hand. This isolates mechanical from electrical issues immediately. He checks post plumb with a digital level, measures rail deflection, and inspects every weld and hinge for cracks or corrosion.
- 3
Transparent quote with options. We explain what’s broken, why it broke, and how we’ll fix it — with pricing for the repair, and honest guidance on when replacement makes more sense. No hidden fees, no pressure. Estimates are free.
- 4
Parts replacement and on-site welding. With parts stocked on our truck and welding equipment ready, most repairs proceed immediately. We cut, grind, fit, weld, and finish in sequence — no subcontracting, no return visits. For custom fabrication, we measure twice and weld once.
- 5
Operational testing and cleanup. We reconnect power, cycle the gate through its full range, test safety entrapment features, and verify latch and lock function. You sign off only when everything works as it should. We leave the site cleaner than we found it.
How Much Does Gate Parts & Welding Cost in San Francisco?
A typical hinge replacement in San Francisco runs $180–$340 depending on hinge type and whether the mounting plate needs welding. Post replacement ranges $450–$850 for residential gates, with deeper excavation and concrete work pushing toward the higher end on hillsides. Rail repair and custom welding generally fall between $280–$620 based on material, accessibility, and finish matching. Gate roller replacement averages $150–$290 per roller assembly, and latch or lock upgrades run $120–$380 depending on mechanical versus electronic components.
| Service | Typical Range in San Francisco |
|---|---|
| Hinge Replacement | $180 – $340 |
| Post Replacement | $450 – $850 |
| Rail Repair / Custom Welding | $280 – $620 |
| Gate Roller Replacement | $150 – $290 per assembly |
| Latch & Lock Upgrade | $120 – $380 |
Several factors move pricing within these ranges. Hillside properties in Bernal Heights or Potrero Hill often require longer posts and more excavation. Historic ornamental iron in Pacific Heights or the Marina demands finish-matching that adds labor. Emergency calls outside standard hours carry a premium we disclose upfront. The best way to avoid overpaying is getting multiple quotes that specify the same scope — and checking that the technician stocks parts and welds on-site, so you’re not paying for a second trip. Our free estimate includes all labor, materials, and testing with no obligation.
