AUTOMATIC GATE REPAIR IN SAN MATEO, CA
San Mateo covers a lot of ground for one city. Down by the water you've got Shoreview and the marina flats. Downtown runs on parking gates and commercial rollers. And up past Crystal Springs Road, the Highlands sits on a ridge where driveways slope hard and the afternoon wind never really lets up. Each of those settings breaks a gate in its own way, and we've repaired gates in all of them.
911 Garage Doors and Gates provides same-day automatic gate repair across San Mateo, CA, covering the 94401, 94402, and 94403 zip codes. Our technicians service every major operator brand, FAAC, DoorKing, LiftMaster, Elite, Viking, Eagle, and US Automatic, on swing gates, sliding gates, and underground systems. We're licensed as a California contractor (CSLB #1098597), insured and bonded, and hold a 5.0-star rating from 300+ verified reviews.
One week it's an estate swing gate in San Mateo Park that stopped short of the latch, the next it's a slider that jumped its track behind a Hillsdale duplex. We show up with parts on the truck and finish most repairs in a single visit. Call 510-458-2048 and the voice on the other end belongs to a technician, not a call center.
GATE OPENER & MOTOR REPAIR
Most gate calls in San Mateo start with the operator, the motor and control unit that does the actual work. Here's what we diagnose and fix on the first trip:
- Gate won't open or won't close
- Stops or reverses partway through
- Remote and keypad stopped responding
- Motor hums but nothing moves
- Grinding or clicking during travel
- Gate frozen after a power outage
- Photo eyes causing false reversals
- Dead control boards and receivers
Location matters here. Salt air off the bay corrodes contacts in Shoreview, fog and wind wear on everything up the hill, and a short PG&E blink can strand a gate halfway across the driveway. So we stock control boards, receivers, photo eyes, limit switches and backup batteries for the major brands, which means most opener repairs don't need a second visit. And when an operator is truly done, we'll say so plainly and install a new LiftMaster, FAAC, or DoorKing unit sized for your gate's real weight.
GATES IN THE SAN MATEO HIGHLANDS
If you live in the San Mateo Highlands, you already know the neighborhood is hard on equipment. This is classic Eichler territory, mid-century homes strung along the ridge above Polhemus, and the same exposure that gives you the views gives your gate a beating. The wind up there is relentless on a swing gate, it loads the leaf like a sail and strains the hinges and operator arms with every gust.
Sloped driveways add their own trouble. A swing gate on a grade needs the right hinge geometry or it drags at the low end. A slide gate needs a level, well-drained track or winter runoff packs it with grit. We set operators up with the torque and travel limits these driveways actually require, and for owners who care about clean mid-century lines we install low-profile and underground operators that stay out of sight. FAAC's in-ground hydraulic units are a favorite in the Highlands for exactly that reason. We've worked on gates along Lexington, Yorktown, and Ticonderoga often enough to know what the ridge does to hardware, and since the neighborhood sits a good ten minutes from any parts counter, we bring everything with us.
- Wind-strained hinge and arm repair
- Slide track cleaning and drainage fixes
- Underground FAAC operator service
- Battery backup for hilltop outages
HILLSDALE & MID-CENTURY HOMES
Hillsdale is a different animal. The mid-century blocks around the shopping center, from 25th Avenue down through the streets off Hillsdale Boulevard, sit on flatter lots, and many of their gates were added decades after the houses went up. Retrofit gates come with retrofit problems: undersized openers, wiring runs patched one too many times, posts that were never set for the load they carry.
We straighten out those installs every week. Sometimes that means swapping a struggling opener for one rated to the gate's actual weight. Sometimes it's rehanging a sagging leaf so it stops scraping the driveway, or running fresh low-voltage wire so the keypad finally works in the rain. Traffic near the mall stays busy late, so plenty of Hillsdale homeowners just want the gate closing reliably every night. We also service the condo and townhome complexes in the area: shared entry gates, garage grilles, and the remotes and keypads that go with them. And since a lot of these houses have been remodeled in the last few years, we're careful to match new hardware to the style of the home rather than fight it. A crisp new fence deserves better than an opener from 1998.
SWING & SLIDING GATE REPAIR
The neighborhoods off Alameda de las Pulgas hold some of the prettiest gates on the Peninsula. San Mateo Park has classic estate swing gates hung on brick and stone pillars under trees that have been there a century. Baywood and Aragon are full of Spanish and Tudor homes where the gate matches the architecture, and replacing it with something off the shelf would be a shame. So we repair what's there.
- Sagging or dragging swing gates
- Hinge rebuilds and replacement
- Slide gate roller and track repair
- Chain and gear drive service
- Gates knocked off track or derailed
- Post, pillar, and mounting repairs
- Safety loop and photo eye installation
- Scheduled preventive maintenance
Heritage trees are lovely and brutal at the same time. Roots lift slide tracks, leaf litter blinds photo eyes, and a heavy iron leaf that's dropped half an inch will chew through a hinge pin in a season. Baywood owners in particular tend to have wood gates that swell every winter and shrink back every summer, so we set clearances that survive both seasons. We repair with OEM or better-grade parts, and we'll tell you straight when a component should be replaced instead of patched again.
COMMERCIAL GATES & INTERCOMS
Downtown San Mateo and the corridors along El Camino Real and Delaware Street keep us busy on the commercial side: parking garage gates for offices and apartment buildings, rolling gates on contractor yards, and sliders securing lots near the Caltrain stations. Commercial gates cycle many times more than residential ones, so we offer priority response and maintenance plans that keep tenants and customers moving. We also look after church, school, and medical office lots around downtown, the kind of places where a gate that fails on a Sunday still needs someone to answer the phone.
We handle the access side too. That covers DoorKing and LiftMaster telephone entry systems, cellular intercoms that ring your phone wherever you happen to be, keypads, card readers, and video entry. But if your building manager is still buzzing every visitor in by hand, there's a better way, and we'll design a system that runs itself. See our access control systems page for the full lineup.

SAN MATEO GATE REPAIR FAQ
Do you offer same-day automatic gate repair in San Mateo?
Yes. Call before mid-afternoon and we can usually have a technician at your San Mateo property that same day. A gate that's stuck open leaves the property unsecured, so we bump those calls ahead of everything else on the board.
Can you handle sloped driveway gates in the San Mateo Highlands?
All the time. Highlands driveways combine steep grades, ridge wind, and mid-century Eichler homes whose owners want the original look preserved. We correct hinge geometry and operator torque for the slope, repair wind-strained hardware, and install low-profile or underground operators that don't clutter the lines of the house.
How much does automatic gate repair cost in San Mateo?
Typical opener repairs come in at $250 to $650, mechanical repairs at $250 to $800, and a new operator installed at $1,200 to $3,000. Intercom systems run $600 to $2,500 installed. You get a firm quote on site before any work begins.
Which gate opener brands do you service?
FAAC, DoorKing, LiftMaster, Elite, Viking, Eagle, US Automatic, and most other major brands, on swing, slide, and underground operators alike.
My gate won't close all the way. What's usually wrong?
Nine times out of ten it's a safety input: a photo eye knocked out of alignment, leaves blocking the beam, or a failing loop detector. Sometimes the travel limits have simply drifted. We diagnose it on site, and most of these are fixed in a single visit.
My gate quit during a power outage. Can I still get out?
Yes. Nearly every operator has a manual release that lets you swing or slide the gate by hand, and we'll gladly walk you through yours over the phone. If outages hit your street often, and up in the Highlands they do, we can add a battery backup so the gate keeps moving even when the block goes dark.
Do you work on shared gates for condos and HOAs?
Yes. We service community entry gates, garage gates, and telephone entry systems for complexes around Hillsdale, downtown, and Shoreview, and we offer maintenance plans that keep board members from fielding late-night gate calls.
