Fast, Reliable Gate Parts & Welding Across San Bruno
Gate parts and welding repair in San Bruno typically costs $180–$650 depending on the component, with most hinge, post, and rail jobs completed same-day. For homeowners in the 94066 ZIP code dealing with aging wrought-iron or chain-link gates, we stock the hardware and welding equipment to fix structural failures on the spot rather than ordering parts and waiting.
Frank and his team have been fixing gates for 20 years, and San Bruno’s older housing stock is familiar territory. From the postwar tracts near San Bruno Avenue to the hillside homes off Skyline Boulevard, we see the same patterns: corroded hinge pins on 60-year-old wrought-iron gates, leaning posts in crumbling concrete, and bent frames from the relentless wind that funnels through the San Bruno Gap. We’re usually on-site in San Bruno within a few hours of your call. Reach us at (855) 671-2951 for a free estimate.
Why Sierra Gate Repair San Diego Is San Bruno’s Preferred Gate Parts & Welding Company
San Bruno homeowners don’t need a handyman who occasionally fixes gates. They need someone who recognizes a fatigued 1950s hinge pin before it snaps, who knows that a leaning post on El Camino Real probably means the original concrete footing has cracked from wind load, and who carries stainless-steel hardware rated for salt-air corrosion.
Our Gate Parts & Welding team has built that expertise over two decades focused exclusively on gates — not fences, not general contracting, just gates. Frank Delgado still runs the jobs himself. You get 20 years of field experience, not a rotating crew figuring it out as they go.
That focus shows in the numbers: 375 verified reviews averaging 4.9 stars. San Bruno customers specifically mention our ability to source obsolete parts for old systems and our willingness to weld and fabricate components rather than pushing unnecessary full-gate replacements.
We also understand the urgency. A gate that won’t latch or a post that’s sheared off leaves your property exposed. We prioritize San Bruno calls and carry common hinge sizes, post brackets, and welding gear on every truck.
Our Gate Parts & Welding Services in San Bruno
Hinge Replacement
Wrought-iron gate hinges in San Bruno fail faster than almost anywhere on the Peninsula. The San Bruno Gap funnels salt-laden marine air directly through the city, and that moisture pits steel hinge pins and seizes bushings within years rather than decades. We replace corroded hinges with stainless-steel or zinc-plated hardware rated for coastal exposure, and we often upgrade the mounting plates because the original wrought-iron ears have thinned from rust. A typical hinge replacement on a residential driveway gate in San Bruno runs $180–$340, including hardware and labor.
Post Replacement
Gate posts set in original 1950s concrete footings lean over time, especially when they’re perpendicular to the prevailing northwest wind that screams down the Gap corridor. We recently pulled a corroded FAAC swing-gate opener from a 1950s tract home on Adeline Drive in San Bruno. The wind had blown salt-laden marine air through the gap for decades, pitting the opener’s gearbox and snapping the springs; we replaced them with stainless-steel hardware and repacked the concrete post base to stop the lean that had set in. Post replacement with a new steel post set in reinforced concrete typically costs $450–$650 in San Bruno, depending on depth and soil conditions.
Rail Repair
Bent or cracked top and bottom rails on wrought-iron and chain-link gates are common here. Wind load racks the frame, and once a rail is compromised, the whole gate geometry shifts. We straighten minor bends with hydraulic equipment and cut out and weld replacement sections for cracks or severe deformation. For San Bruno’s older gates, we often fabricate matching rail profiles from steel stock because original extrusions haven’t been made in 40 years. Rail repair ranges from $220–$480 depending on length and whether we need to match ornamental details.
Custom Welding
Our mobile welding rig lets us fabricate and repair structural components on-site rather than hauling gates to a shop. We’ve rebuilt broken corner joints on hillside gates off Crestmoor Drive, added reinforcement gussets to sagging frames near Centennial Park, and fabricated custom strike plates when original hardware is no longer manufactured. Custom welding in San Bruno starts around $280 for simple repairs and runs higher for extensive fabrication or ornamental matching.

Trusted Brands We Service in San Bruno
We work on virtually every major gate brand, including FAAC, BFT, and Linear — no referrals, no guesswork. For San Bruno’s older installations, this matters because many homes still run early LiftMaster or Elite operators from the 1980s and 1990s, and parts availability is increasingly spotty. Our two decades of accumulated parts knowledge and supplier relationships means we can often source obsolete components faster than generalist competitors, or we can fabricate mechanical interfaces when a direct replacement is no longer manufactured. If your operator is truly at end-of-life, we’ll tell you straight and quote a modern Viking or Linear replacement that fits your existing gate geometry.
Common Gate Parts & Welding Problems We See in San Bruno Homes
- Salt-laden Gap wind accelerates rust on wrought-iron hinges and springs, causing fatigue cracks and sudden failure. The marine moisture carried through the San Bruno Gap is more corrosive than the drier air just a few miles south in Burlingame, and we replace pitted hinge pins and broken springs here at roughly twice the rate we do in Millbrae.
- Gate posts set in original 1950s concrete footings lean over time due to persistent northwest wind load, racking the frame. Technicians here learn quickly that posts installed perpendicular to the prevailing wind direction will rack and lean, so re-plumbing and re-setting gate posts in reinforced concrete footings is almost routine in San Bruno, not an occasional upsell.
- Original chain-link gate rollers seize from corrosion and wind-borne grit, tearing roller tracks and jamming gates. The same Gap winds that corrode hinges also blast fine particulate into roller mechanisms, accelerating wear on older steel and early nylon rollers.
- Early automatic opener gearboxes fail from decades of salt-air exposure, particularly on homes near the flatlands between San Bruno Avenue and El Camino Real where the wind corridor is most concentrated. The pitting and moisture ingress we find inside these units is far more severe than in protected inland locations.

We don’t quote over the phone without seeing the gate, but we do provide firm, upfront pricing once we’re on-site. Estimates are free. Call (855) 671-2951 to schedule.
We Also Serve Cities Near San Bruno
Our mobile welding and parts trucks cover the full Peninsula corridor, including Millbrae, South San Francisco, Pacifica, and Burlingame. Each city has its own microclimate and housing patterns — Pacifica’s direct ocean exposure is even harsher on hardware, while Burlingame’s calmer air and newer stock means different failure modes. We adjust our materials and approach accordingly.

FAQs — Gate Parts & Welding in San Bruno
The San Bruno Gap funnels salt-laden marine air directly through your property at higher velocity and concentration than in neighboring cities. That moisture penetrates standard steel hinge pins and bushings, accelerating oxidation by a factor of two or more compared to calmer Peninsula microclimates. We replace them with stainless-steel or marine-grade zinc hardware and use anti-seize compound during installation. Call (855) 671-2951 for an inspection — estimates are free.
Welding a leaning post rarely works long-term because the root cause is almost always a cracked or undersized concrete footing that’s succumbing to San Bruno’s persistent northwest wind load. We remove the post, excavate the old footing, and set a new steel post in reinforced concrete at proper depth. The weld would crack again within months. Most post replacements in San Bruno run $450–$650. Call (855) 671-2951 and we’ll assess whether the post is salvageable.
We stock and source parts for vintage LiftMaster, Elite, and Mighty Mule operators, and our supplier relationships let us locate obsolete components that aren’t available through retail channels. If the part is truly discontinued, we can fabricate mechanical adapters or recommend a modern replacement that preserves your gate geometry. We service nine major brands including Linear and Viking for upgrades. Call (855) 671-2951 with your model number.
It depends on the frame condition and your budget. If the wrought-iron frame is structurally sound — no cracks, minimal rust scaling, good weld integrity — a spring replacement with upgraded stainless-steel hardware is the practical choice, typically $220–$380. If the frame is racked, heavily corroded, or missing ornamental castings that can’t be matched, we quote both repair and replacement options. We’re not interested in selling you a gate you don’t need. Call (855) 671-2951 for an honest assessment.
Most likely the rollers have seized from corrosion and wind-borne grit, or the track itself has bent from a failing post or impact. We see this constantly in San Bruno’s older neighborhoods where original nylon or steel rollers have disintegrated after decades of Gap-wind exposure. We replace rollers with sealed-bearing units, straighten or replace damaged track, and check the post plumb. Typical repair is $200–$360. Call (855) 671-2951 to get it moving again.
