Fast, Reliable Gate Repair Across San Bruno
Gate repair in San Bruno typically costs between $180 and $650 depending on the damage, and most repairs are completed same-day or next-day. If your gate is sagging, sticking, or won’t latch properly, the San Bruno Gap winds are likely the culprit — and that’s a problem generalist handymen often misdiagnose.
We’re Sierra Gate Repair San Diego, and our Gate Repair team makes regular runs up the Peninsula to San Bruno. Frank Delgado and his crew have been fixing gates for 20 years, and we’ve learned that gates in 94066 face challenges you won’t find in calmer microclimates just a few miles away. The salt-laden wind tearing through the Gap between San Bruno Mountain and the Santa Cruz Mountains doesn’t just make for brisk afternoons — it racks posts, seizes hinges, and snaps corroded weld joints on aging wrought-iron and chain-link gates throughout the city’s postwar neighborhoods.

Why Sierra Gate Repair San Diego Is San Bruno’s Preferred Gate Repair Company
Our reputation in San Bruno was built one repair at a time. We’ve worked on driveway gates near Skyline Boulevard, side-yard gates in the Crestmoor area, and commercial access gates along El Camino Real. 375 customers have left verified reviews averaging 4.9 stars — that kind of track record comes from showing up, diagnosing correctly, and fixing it properly.
Frank Delgado still runs the jobs personally. You get the founder’s expertise on-site, not a rotating crew of subcontractors who might recognize a LiftMaster motor but have never seen what Gap winds do to a 1960s steel post set in crumbling concrete. We’re usually in San Bruno within a day of your call, sometimes same-day if the gate is compromised and you need security restored fast.
We also stock parts and carry welding equipment. That matters in San Bruno, where many gates are too old for off-the-shelf replacement and need field fabrication.
Our Gate Repair Services in San Bruno
Hinge Repair
San Bruno’s salt-laden Gap winds turn hinge pins into rusted, seized cylinders within a few years — especially on original 1950s and 1960s wrought-iron gates that were never galvanized. We drill out corroded pins, ream the knuckles clean, and install stainless or zinc-plated replacements rated for marine exposure. A typical hinge repair in San Bruno runs $180–$280. If the hinge has torn away from the frame, we’ll weld it solid.
Post Repair
This is where San Bruno’s wind corridor really shows its teeth. Posts installed perpendicular to the prevailing northwest wind — which blasts hard down the Gap — rack and lean over years of sustained lateral pressure. We replaced a corroded hinge pin and reset a leaning post on a 1950s wrought-iron driveway gate near the Crestmoor neighborhood; the original concrete footing had cracked from years of salt-laden wind vibration, and we poured a reinforced footing to handle the gap winds. Post repair or replacement with reinforced concrete in San Bruno typically costs $350–$650.
Weld Repair
Aging welds on original tract-home gates crystallize and crack under cyclical wind loading. We bring portable welding gear to every San Bruno job, so split frames, broken scrollwork, and detached latch plates get repaired on-site rather than farmed out. Most weld repairs run $200–$400. For gates with extensive corrosion, we’ll tell you honestly when welding is a temporary fix and replacement makes more sense.
Gate Realignment
When posts lean or hinges wear unevenly, gates drag, bind, or refuse to meet the strike plate. In San Bruno, we see this constantly on sloped lots near Rollingwood and Portola Highlands, where wind-racked posts compound grade issues. We plumb the gate, shim or reset hardware, and adjust the automatic opener travel limits if present. Realignment alone typically runs $180–$320.
Lock Repair & Rust Treatment
Gate locks in San Bruno seize from internal corrosion faster than inland cities because marine moisture penetrates the mechanism. We replace mortise locks, magnetic latches, and electronic strikes, or convert manual gates to keyless entry. Rust treatment — wire brushing, phosphoric acid conversion coating, and cold-galvanizing spray — extends the life of salvageable steel gates by several years. Rust treatment and lock repair together typically run $220–$380.

Trusted Brands We Service in San Bruno
We work on virtually every major gate operator brand — no referrals, no guesswork. In San Bruno, we regularly service LiftMaster residential swing and slide operators, FAAC commercial hydraulic systems on apartment complexes near El Camino Real, and Mighty Mule DIY units that homeowners install and later need professionally tuned. Our van carries common LiftMaster and FAAC control boards, limit switches, and safety sensors, so San Bruno customers aren’t waiting a week for parts to ship. With 20 years of supplier relationships, we can source proprietary components for older Elite and DoorKing systems that most competitors won’t touch.
Common Gate Repair Problems We See in San Bruno Homes
- Wind-racked posts leaning toward the street or driveway. The San Bruno Gap exerts sustained lateral force that inland Peninsula cities simply don’t experience. Posts set in standard concrete footings crack and tilt within 5–10 years unless reinforced with rebar and deeper excavation.
- Corroded hinge pins seized solid or snapped clean through. Salt-laden marine moisture accelerates rust on steel hardware significantly faster than in calmer microclimates just a few miles south. Gates that should swing freely grind and shudder instead.
- Original 1950s–1960s wrought-iron gates with failing field welds. These aging gates frequently show crystallized, cracked joints that snap under sustained wind loads. The metal itself may be salvageable; the welds usually aren’t.
- Automatic openers straining against misaligned gates and burning out motors. When wind-racked posts cause binding, the operator works harder, overheats, and fails prematurely. We fix the gate first, then address the motor.

FAQs — Gate Repair in San Bruno
San Bruno sits directly within the San Bruno Gap, a wind corridor between San Bruno Mountain and the Santa Cruz Mountains that funnels persistently strong winds far more intense than in neighboring Millbrae or South San Francisco, causing extraordinary lateral stress on gate posts, hinges, and latches year-round. Posts installed perpendicular to the prevailing northwest wind rack and lean over years of sustained pressure. We address this by resetting posts in reinforced concrete footings with rebar — standard practice here, overkill elsewhere. Call (855) 671-2951 for a free post assessment.
The San Bruno Gap winds carry salt-laden, high-humidity airflow from the Pacific that accelerates rust and corrosion on iron and steel gate hardware significantly faster than inland Peninsula cities. Gate springs, hinges, and strike plates exposed to this wind-driven moisture require more frequent lubrication and replacement than in calmer microclimates just a few miles south. We use marine-grade stainless or zinc-plated hardware for San Bruno repairs, and we offer rust treatment to extend the life of salvageable steel gates.
Replacing a gate post in San Bruno typically does not require a permit if you’re maintaining the same gate location, height, and function; however, if you’re altering the fence line, increasing height, or installing a new automatic operator, San Mateo County or city permitting may apply. We can advise on whether your specific job triggers permit requirements during our free estimate. For straightforward post replacement, we usually complete the work same-day without bureaucratic delay.
Most original wrought-iron gates in San Bruno’s postwar tract homes can be reinforced rather than replaced, provided the frame metal hasn’t thinned from corrosion. We evaluate the gate on-site: if the scrollwork and rails are structurally sound, we weld gussets, replace corroded hinge pins with marine-grade hardware, and ensure posts are properly anchored. If the metal is too far gone, we’ll tell you honestly and quote a replacement. Many 50–70-year-old gates in the Crestmoor and Rollingwood areas have years of life left with proper reinforcement.
Aluminum with a reinforced internal frame offers the best strength-to-weight ratio for San Bruno’s Gap winds — it won’t rust like steel and is lighter on operators and hinges. Powder-coated steel with galvanizing underneath is also suitable if you commit to periodic rust treatment. We don’t recommend untreated wrought iron or standard chain-link for new installations in 94066; the marine exposure is too aggressive. For existing gates, proper maintenance and hardware upgrades are usually the most cost-effective path. Call (855) 671-2951 to discuss whether your current gate can be upgraded or needs replacement.
