AfterFast, Reliable Gate Access Control Across San Francisco
Gate access control in San Francisco has two jobs at once: keep the wrong people out and keep your own entry working on a street where parking is tight, driveways are shared, and the fog is always working against the hardware. We’ve spent years fixing keypads, remotes, phone entry, and card readers on properties from SoMa to Visitacion Valley, and we know which parts hold up here and which ones don’t. If your gate won’t open, won’t close, or won’t recognize a code, call (877) 610-2993 and talk to a live person who knows San Francisco’s unique gate problems.
Most days we can have a truck to your block the same day. The name on the invoice is Hal Gatewood’s, and he’s been at this since 2001. That matters when the gate is the only thing between your front door and the street.
Why Gatewood Fence & Gate Is San Francisco’s Preferred Gate Access Control Company
We’re not a call center and never will be. When you phone us about an access control problem in the Mission or Noe Valley, the person who answers knows what a zero-setback lot line means and why a swing gate won’t fit your driveway. That local knowledge saves you time and money. We’re locally owned and owner-operated, with a published address and license number anyone can look up. Hal Gatewood’s name is on the shop and on every invoice.
San Francisco homeowners hear horror stories about out-of-area outfits quoting one price and charging another at the door. We don’t work that way. Every price is agreed before the work starts, in writing. Every job carries a 90-Day Done Right Promise. If it’s not done right, one call brings us back. No runaround, no hedging.
We also answer the phone around the clock. A live person, 24/7. When your gate locks you out at 11 p.m. in Chinatown or your keypad dies before work in SoMa, you don’t want voicemail. You want someone who can send help or talk you through a temporary fix.
Our Gate Access Control Services in San Francisco
Choosing the right access control system in San Francisco isn’t like choosing one in a flat suburb with wide drives and single-family lots. It starts with how your gate sits on the property, how the fog treats the electronics, and who needs to get in and out every day. Here’s what we install, repair, and service across the city.
Keypad Entry
Keypad entry is the workhorse for San Francisco’s shared driveways and multi-unit buildings. We program multiple user codes so each household, tenant, or employee has their own. Common failures here are salt-corroded keypad terminals and water intrusion through the membrane when fog sits on the housing for hours every morning. We use sealed keypads and orient them away from the prevailing west wind. A typical keypad entry install or repair in San Francisco runs $145-$385 depending on wiring condition and how many codes you need programmed.
Loop Detector
Loop detectors are the buried wire sensors that tell a gate to open for a car but not for a person or an animal. In San Francisco, the saw-cut channel in your asphalt or concrete picks up salt-laden moisture, and the lead splices corrode faster than anywhere inland. Symptoms include phantom opens when no car is present, or no open at all when you’re sitting right on top of the loop. We replace the loop, re-seal the channel, and reprogram the controller so it stops false-triggering. Loop detector replacement in San Francisco typically runs $280-$520 installed.
Remote Control
Remotes are simple until they’re not. The hills change the game: where a car positions itself on an uphill or downhill approach determines how far from the gate the remote signal has to reach. We test for range under real conditions - not in a flat parking lot - and replace or reprogram remotes on site. We carry remotes compatible with Viking, Ghost Controls, and DoorKing operators on our trucks, so most remote replacements happen same day. Expect $85-$185 for a new remote programmed and tested at your driveway.
Phone Entry
Phone entry systems let a visitor call your cell or a landline from a box at the gate, and you buzz them in. On Nob Hill and Russian Hill, these systems fail when the copper phone lines feeding the century-old buildings degrade or when the entry unit’s internal battery swells from temperature swings between fog and afternoon sun. We install and service cellular-based phone entry units that don’t depend on aging building wiring. Phone entry system install in San Francisco generally runs $650-$1,400, depending on whether we’re replacing an old hardwired unit or starting fresh.

Trusted Brands We Service in San Francisco
We’re certified to service and install Gate Access Control systems from nine major brands, including DoorKing, Viking, and Ghost Controls. We stock common parts for those three on our trucks, which means most repairs in San Francisco don’t wait on a parts delivery. When a Viking operator in the Mission fails, we’re not calling around town trying to find a control board. It’s on the shelf. That’s the difference between a gate that’s down for hours and one that’s working by the end of the day.
Common Gate Access Control Problems We See in San Francisco Homes
Every city has gate failures. San Francisco has its own set, driven mostly by the two things no gate company can change: the hills and the fog. Here are the problems we fix most often.
- Downhill gate drift on Nob Hill and Russian Hill. Inward-swinging driveway gates that open downhill slowly drift past the latch and refuse to stay closed. The problem isn’t the latch - it’s the hinge spring tension, which has to be calibrated for the grade or the gate will keep wandering. Out-of-area techs replace the latch hardware and the gate drifts open again in a week.
- Salt-corrosion inside loop detector splices. The saw-cut channel in the driveway collects fog moisture, and the wire splice inside slowly turns green and powdery. That’s what causes a gate that opens for no reason, or won’t open when you’re sitting right on it.
- Rotted post footings on old Victorians. Those 80-to-120-year-old iron pedestrian gates in Noe Valley and the Mission are beautiful, but their post footings have spent a century absorbing fog moisture. When the post shifts even an eighth of an inch, a new safety photocell can’t hold alignment, and the gate refuses to close.
- Tight-clearance conflicts on shared driveways. On a 25-foot-wide lot, a swing gate can clip the neighbor’s wall or a parked car. We convert these to slide gates, which run on a track and need almost no arc. That often requires re-bedding the rack and pinion on a fresh post footing, which we do on site.

FAQs - Gate Access Control in San Francisco
The latch wasn’t the problem. On a sloped driveway, the gate’s own weight pulls it downhill past the latch point unless the hinge spring tension is deliberately calibrated for that grade. In flat cities this failure almost never happens, so an out-of-area tech replaces the latch and thinks it’s fixed - then the gate drifts again within days. We set the hinge springs to compensate for the slope and the gate stays put. If your Russian Hill gate is drifting, call (877) 610-2993 and we’ll fix the spring tension, not just swap parts.
Fog deposits salt-laden moisture on the keypad membrane every single morning, even in the dry season. Salt working into the terminals causes buttons that don’t respond, random code rejections, or a keypad that works half the time. We install sealed keypads and angle them away from the prevailing wind, and we use marine-grade connectors on the wiring. A fog-resistant keypad in San Francisco runs $145-$385 installed. Call (877) 610-2993 for an exact quote.
Yes. On a 25-foot lot, a swing gate usually won’t work because the arc would clip the neighbor’s wall or a car parked in the shared driveway. We convert to a slide gate, which moves parallel to the fence line and needs almost no swing clearance. We handle the rack and pinion, the post footing, the operator, and the programming. A tight-clearance slide gate install in San Francisco runs $3,200-$7,500 depending on gate size and how much of the existing post structure we can keep. Call (877) 610-2993 for a free measure and written price.
Gate openers in San Francisco must meet UL 325 entrapment standards, which means photo eyes, contact edges, or both, plus a reversing mechanism. On steep driveways in 94108 and 94109, we also have to account for gravitational load - a gate that fails safe on a downhill slope can still be a hazard. We install and test entrapment protection to code on every automatic gate we touch, including the older Victorian-era pedestrian gates where adding a photo eye takes careful alignment. Call (877) 610-2993 if you’re not sure your gate meets current standards.
We stage the work so the gate is never down for the whole day. On a recent shared driveway in the Mission, we replaced a corroded DoorKing slide gate operator with a slope-rated FAAC unit, re-bedded the rack and pinion on a fresh post footing, and programmed the keypad so both households kept separate codes while a loop detector held the gate for the downhill car. Vehicle access was never blocked for more than an hour at a stretch, and pedestrian access stayed open throughout. Call (877) 610-2993 to schedule a repair that keeps your driveway working while we fix the gate.
