After 17 years working exclusively on gates across San Francisco, we’ve learned that most gate failures aren’t motor problems. They’re metal fatigue. Hinges seize in the salty fog rolling off the bay. Posts lean in the clay-heavy soil of Noe Valley. Rails crack where the daily stress concentrates. When that happens, you need someone who can cut, weld, and fabricate right there on your property, not a handyman who’ll call three other people.
Carlos Estrada built Anchor Gate Repair on exactly that capability. As owner and service manager, he’s personally handled thousands of gate repairs in San Francisco, from Victorian-era iron walk gates in Pacific Heights to modern automated driveway systems in Visitacion Valley. Our team welds, fabricates, and repairs on-site. We work on the brand you already have, whether that’s a Ghost Controls swing gate in the Mission District or a DoorKing slide gate near Chinatown. And 304 customers reviewed us at 4.8 stars, because we fix it right the first time.
What Our Gate Parts & Welding Service Includes
Hinge Replacement
Hinges are the most abused component on any gate. In San Francisco, the combination of marine air and frequent use causes pin wear, bushing failure, and eventually sagging or binding. We stock heavy-duty ball-bearing hinges, oil-impregnated bronze bushings, and custom-fabricated pintle hinges for older iron gates. When we perform hinge replacement, we also check the post attachment, because a new hinge bolted to rotted wood or cracked welds will fail again within months.
Post Replacement
A leaning or rotted post makes every other gate part work harder. In the Mission District and surrounding neighborhoods, we regularly see pressure-treated posts that have succumbed to ground moisture or termite damage after 10–15 years. We set new steel or aluminum posts in concrete with proper drainage, or we can fabricate and weld custom post brackets when standard hardware won’t fit your existing masonry or retaining wall. Carlos and his team measure twice, because a post set even slightly off-plumb will cause years of alignment headaches.
Rail Repair
Horizontal rails carry the gate’s weight and take the impact when vehicles or delivery carts bump through. Cracked or bent rails aren’t just cosmetic. They transfer stress to hinges, motors, and latches in ways that cause cascading failures. We cut out damaged rail sections and weld in replacement steel or aluminum stock, matching the original profile and finish. For ornamental iron gates common in older San Francisco neighborhoods, we’ll fabricate matching scrollwork or picket details so the repair disappears visually.
Custom Welding
This is where generalist shops typically stop and we keep going. Our mobile welding rig runs 220V MIG and TIG capability, so we can repair cast iron, steel, stainless, and aluminum gate components on-site. We’ve fabricated everything from custom welding projects like catch posts for odd-angle driveways in the hills to security cages for access control equipment in commercial lots. Because Carlos oversees every weld personally, we don’t subcontract structural work to someone you’ve never met.
Gate Rollers
Slide gates depend on rollers that stay true through thousands of cycles. In San Francisco’s variable terrain, we see roller failure caused by track misalignment, debris buildup, and bearing corrosion. We stock gate rollers including V-groove, flat, and cantilever assemblies for gates up to 2,000 pounds, and we’ll true or replace bent track sections as part of the repair. If your slide gate has started grinding or jumping the track, the rollers are telling you something before the motor burns out.
Latch & Lock
A gate that won’t latch securely is a gate that isn’t doing its job. We replace standard gravity latches, install keyed-alike systems for multi-tenant properties, and integrate electric strikes with your existing access control. For historic properties in neighborhoods like Noe Valley, we can fabricate custom latch hardware that matches period details while meeting modern security needs. The latch & lock is often the cheapest part to fix and the most important for daily function.

Brands We Service for Gate Parts & Welding
We carry parts and service equipment from nine major manufacturers, which means you rarely need a second company regardless of what’s installed. For Elite operators, we’ve serviced hundreds of their slide and swing gate systems and stock their OEM limit switches, circuit boards, and gear assemblies. When an Elite gate in San Francisco needs structural reinforcement to the frame, we handle both the electronic diagnosis and the welding in the same visit.
Mighty Mule systems are common on residential properties throughout the Bay Area, and we keep their control arms, control boxes, and safety sensor kits in stock. We’ve also fabricated custom mounting brackets when standard Mighty Mule hardware doesn’t align with existing gate geometry. Ghost Controls and DoorKing round out our most frequently serviced brands in San Francisco. Whether you have one of these or any other make, we can help. Our home page lists our full service range, and our Gate Parts & Welding in Mission District page covers this same service in that specific neighborhood.
Signs You Need Gate Parts & Welding Right Now
- The gate sags or drags on the ground. Sagging indicates hinge wear, post settlement, or rail fatigue. Left unaddressed, the gate motor works harder, draws more amperage, and eventually burns out. We’ve replaced motors that failed prematurely because the underlying structural problem was ignored for six months.
- You see rust, cracks, or separation at welded joints. San Francisco’s marine climate accelerates corrosion at weld points and heat-affected zones. A crack that starts hairline-thin can propagate through a rail or post in weeks. We grind out cracked welds, prep the metal properly, and lay in fresh bead with matching filler material.
- The latch won’t catch without lifting or slamming the gate. This usually means hinge wear has thrown the gate out of alignment, or the post has shifted. Forcing the latch damages both the latch and the strike plate. We diagnose whether the fix is hinge replacement, post adjustment, or both.
- Roller noise has changed from hum to grind or clank. Bearings don’t fail silently. A grinding roller is metal-on-metal contact that scores the track and eventually jams the gate. We replace rollers before they destroy the more expensive track section.
- There’s visible weld failure on ornamental iron or custom fabrication. Historic gates in neighborhoods like Chinatown and Noe Valley often have original wrought iron work that fatigues at stress points. We match the original fabrication style and can age the finish so repairs blend with patina that’s taken decades to develop.
Our Gate Parts & Welding Process — Step by Step
- 1
On-site diagnosis. Carlos or a senior technician examines the gate in operation, checks for binding points, measures clearances, and identifies whether the problem is parts, structure, or both. We bring a full inventory of common hinges, rollers, latches, and hardware so we can often repair immediately.
- 2
Structural assessment. For welding or fabrication needs, we evaluate metal thickness, existing weld quality, and load paths. We don’t weld over cracks or paint. We grind to clean metal, check for hidden damage, and determine whether reinforcement or replacement makes more sense.
- 3
Transparent estimate. You’ll get a written quote before any work begins, with line-item breakdown of parts, labor, and any custom fabrication. No surprises, no pressure. Our estimates are free and carry no obligation.
- 4
Parts replacement and welding. We install OEM or equivalent-grade parts and perform all welding with proper preheat, penetration, and post-weld treatment for the material. For outdoor gates in San Francisco’s salt-air environment, we use corrosion-resistant finishes and sealants that outlast standard paint.
- 5
Operational testing and adjustment. We cycle the gate fully, check motor draw if automated, verify latch engagement from multiple angles, and confirm safety sensor function. The gate should work better than it did before the problem started, not just “good enough.”
How Much Does Gate Parts & Welding Cost in San Francisco?
A typical hinge replacement in San Francisco runs $150–$280 depending on hinge type and whether the post attachment needs reinforcement. Post replacement usually falls between $400–$750 for standard steel or aluminum posts set in concrete, with complex installations on hills or retaining walls at the higher end. Rail repair and custom welding ranges $200–$650 based on material, access, and whether ornamental matching is required. Gate roller replacement typically costs $180–$340 per roller assembly including track adjustment. Latch and lock work runs $120–$260 for mechanical hardware, or $280–$520 when integrated with electric access control.
Several factors push pricing within these ranges. Material matters: stainless steel and aluminum require different filler rods and techniques than standard carbon steel. Access difficulty adds time, hillside properties in Noe Valley or Pacific Heights often need specialized equipment positioning. Ornamental matching for historic gates requires hand fabrication rather than off-the-shelf parts. And urgency affects scheduling, though we never charge emergency premiums just for same-day response when capacity allows.
To avoid overpaying, get a diagnosis before authorizing work. Some companies quote full gate replacement when targeted welding and parts would solve the problem for a fraction of the cost.

Frequently Asked Questions — Gate Parts & Welding in San Francisco
Gate parts and welding covers the physical repair, replacement, and custom fabrication of gate components including hinges, posts, rails, rollers, latches, and structural metalwork. At Anchor Gate Repair, we perform all welding and fabrication in-house rather than subcontracting, so Carlos and his team control quality from diagnosis through completion. This service applies to both manual and automated gates of any brand or age.
Most hinge, latch, and roller replacements take 1–2 hours on-site. Post replacement typically requires 2–4 hours plus concrete cure time before full loading. Custom welding and rail repair varies with complexity, but we complete most structural work in a single visit using our mobile welding rig. We’ll give you a specific time estimate after seeing your gate. Call (866) 426-1530 to schedule a look.
Typical repairs range from $120 for simple latch replacement to $750 for post replacement with custom fabrication, with most falling in the $200–$400 range. Custom ornamental welding for historic gates or complex access-control integration runs higher based on material and labor. We provide written, itemized estimates before any work begins, and estimates are always free.
Yes. We are factory-familiar with both Elite and Mighty Mule systems and stock common parts for both brands. For Elite operators, we handle circuit board, limit switch, and gear assembly replacement alongside any structural welding the gate frame needs. For Mighty Mule, we install control arms, safety sensors, and custom mounting brackets when standard hardware doesn’t fit your gate geometry.
We prioritize calls where a gate failure creates security or safety concerns, and we maintain same-day capacity for urgent repairs when possible. Our 17 years in San Francisco means we understand that a stuck commercial gate or a residential security failure can’t wait. Call (866) 426-1530 and we’ll tell you honestly whether we can reach you today.
We stand behind our workmanship and parts installation with warranty coverage appropriate to the specific repair. Hinge and roller installations carry standard coverage against premature failure due to material or installation defects. Custom welding is warranted against structural failure in normal use. We’ll explain the specific warranty terms for your repair before you authorize work.
Clear access to both sides of the gate and ensure we can reach electrical outlets if your gate is automated. If the gate is stuck open or closed, don’t force it, that usually makes the underlying problem worse and can damage the motor. Note the brand of any operator or access control equipment, and tell us about any recent changes in gate behavior. The more context you provide, the faster we can diagnose.
