Gate Repair in San Carlos is what we do. Not handyman work. Not “we also do gates.” Gates exclusively, from post rot to operator replacement to on-site welding. Steven Lee, our owner and lead technician, still carries the tools and handles the diagnosis personally.
Why Liberty Gate Repair San Francisco Is San Carlos’s Preferred Gate Repair Company
San Carlos homeowners call us back. That pattern — 613 reviews averaging 4.9 stars — didn’t happen by accident. It happened because Steven diagnoses it, Steven fixes it, and when we leave, the gate works.
We know the difference between a Cordes hillside install and a flat-lot repair near downtown. That local fluency means we don’t waste your morning discovering that your “standard” inward-swing gate needs to become a slide gate because your driveway drops six feet to the street. We’ve made that mistake exactly zero times in 31 years.
Our response time to San Carlos is consistently same-day or next-day for urgent calls — a gate that won’t close is a gate that won’t secure your property. We stock parts and weld on-site, which cuts return visits. Most San Carlos customers are surprised when we show up with a replacement LiftMaster or FAAC operator in the truck, not a promise to “order it and come back.”
Our Gate Repair Services in San Carlos
Hinge Repair
Hinge repair in San Carlos runs $180–$320 for standard residential gates, with corrosion-heavy jobs on the flat eastern side often landing at the higher end. The salt-laden marine layer that rolls in off the Bay doesn’t just make mornings foggy — it actively eats steel. We’ve pulled hinge pins from properties near the Caltrain corridor that have lost nearly half their diameter to oxidation in under five years. Powder coating helps. It doesn’t stop it. When we replace hinges in these neighborhoods, we spec marine-grade stainless or hot-dip galvanized hardware, and we explain why the original part failed.
Post Repair
Post repair in San Carlos typically costs $280–$480, with footing replacement pushing toward $550 if the concrete has heaved or cracked. The post-war housing stock on the flat eastern side — those 1940s-to-1960s single-family homes — often has original wooden gate posts that are simply done. Rot at grade, termite damage, or concrete footing failure from decades of wet-dry cycling. We’ve replaced posts on San Carlos Avenue properties where the original 1958 redwood post had turned to sponge. We pour new footings, set pressure-treated or steel posts, and realign the gate frame in the same visit.
Weld Repair
Weld repair in San Carlos starts around $220 for minor frame cracks and runs to $450 for structural gate frame rebuilding. Our mobile welding capability matters here — we don’t farm out to a third shop. In the hillside neighborhoods above Brittan Avenue, where driveway slope puts constant torque on gate frames, weld failures are common. We’ve repaired steel driveway gates on Crestview Drive where the frame had cracked at the corner from years of gravity loading every time the gate swung. Steven welds it, grinds it, primes it, and the gate goes back to work.
Gate Realignment
Gate realignment in San Carlos costs $160–$290 for adjustment-only jobs, but when the realignment requires new hardware or post work due to slope stress, the total can reach $420–$580. This is where San Carlos’s topography really shows its hand. On steep grades in the White Oaks and Cordes areas, a gate that was “fine” when installed can sag, bind, or drag within two seasons as the ground shifts and the frame torques. We don’t just adjust — we assess whether the original installation geometry was wrong for the slope. Sometimes the fix is a new hinge geometry. Sometimes it’s converting to a slide gate. We tell you which, and why.
Rust Treatment
Rust treatment in San Carlos runs $140–$260 for surface treatment and protective coating, or $320–$480 when combined with component replacement. For flatland properties near the Bay, this isn’t cosmetic — it’s preventive maintenance that extends gate life by years. We grind, treat, and coat steel components with marine-rated finishes. The alternative is replacement. In San Carlos’s eastern neighborhoods, rust treatment pays for itself.

Trusted Brands We Service in San Carlos
We’re factory-familiar with nine major gate brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. That fluency matters in San Carlos because your gate operator isn’t generic — it’s a specific machine with specific failure modes. A LiftMaster LA500 has different corrosion vulnerabilities than a FAAC 402 or a BFT Ares. We stock common operator parts and carry diagnostic tools for each brand, which means when your Ghost Controls system throws an error code on a hillside property off Alameda de las Pulgas, we know what it means without consulting a manual. Fast turnaround because the right part is already in the truck.
Common Gate Repair Problems We See in San Carlos Homes
- Marine-layer corrosion on flatland gates. Properties near the Bay and Caltrain corridor see steel hinges, latches, and operator gearboxes oxidize at rates that would seem excessive anywhere inland. Even galvanized components show premature failure.
- Slope-driven mechanical stress in hillside neighborhoods. Driveways on grades past Brittan Avenue and in the White Oaks area torque gate frames, stretch hinges, and cause chronic misalignment that simple adjustment won’t fix permanently.
- Post rot and footing heave in post-war housing stock. Original wooden gates from the 1940s–1960s on the flat eastern side often have posts that have reached end-of-life, with concrete footings cracked from decades of soil movement.
- Operator failure from humidity exposure. Gate openers mounted in unprotected locations — common on older San Carlos properties — suffer circuit board and gearbox damage from persistent high humidity, not just rain.

FAQs — Gate Repair in San Carlos
The persistent marine layer and salt-laden air off the Bay accelerate steel oxidation by 30–50% compared to inland Peninsula cities. Even powder-coated hinges on flatland properties near the Caltrain corridor show premature rust-through. We spec marine-grade stainless or hot-dip galvanized replacements, which last significantly longer in this environment. Call (628) 261-6223 for a free hinge assessment — estimates are free.
The fix is usually converting from an inward-swing gate to a slide gate or an outward-swing unit with a poured level pad, which prevents the gate from contacting the grade. Standard inward-swing geometry fails on slopes above about 4% grade, which is common on hillside streets west of El Camino Real. We’ve converted dozens of White Oaks and Cordes properties to slide gates that operate cleanly regardless of driveway pitch. Call (628) 261-6223 — we’ll assess your slope and spec the right solution.
A rotted post requires replacement, not repair — wood rot at grade is structural failure, and patching it delays the inevitable. We remove the old post, pour a new concrete footing, and set a pressure-treated or steel post that will outlast the original. For San Carlos’s post-war housing stock, this is one of our most common calls. Call (628) 261-6223 for a free post replacement estimate.
We’ve seen LiftMaster operators in marine-exposed San Carlos locations show circuit board corrosion and gearbox oxidation within 4–6 years, versus 10–12 years in drier inland climates. Mounting location matters enormously — operators tucked under eaves fare better than those in open weather. We can relocate, enclose, or replace with better-sealed units. Call (628) 261-6223 to evaluate your specific exposure.
Repair is usually cheaper if the issue is a single failed component — $280–$450 for a new control board or gearbox — but replacement at $650–$1,100 becomes the better value when the unit is over 10 years old, has multiple failure points, or lacks modern safety features. For BFT units specifically, parts availability is good, but we always weigh repair cost against remaining service life. Call (628) 261-6223 and we’ll give you an honest repair-vs-replace breakdown — estimates are free.
