Fast, Reliable Gate Repair Across Foster City
Gate repair in Foster City usually comes down to two things: a post that has moved in the bay mud, or hardware that the lagoon air has started eating. Most calls we run in the 94404 start with a gate that’s bound at the latch, dragging on the driveway, or an operator that hums but won’t move the gate. We’ve been fixing gates since 2001, and we’re set up to be at your Foster City property fast, with the parts and the welding gear already on the truck. Call (877) 610-2993 and you’ll get a live person, not a phone tree.
Why Gatewood Fence & Gate Is Foster City’s Preferred Gate Repair Company
Hal Gatewood put his name on the shop, publishes his address, and has been owner-operated since 2001. That means the person who answers the phone is the same person who stands behind the work. Foster City homeowners don’t want a rotating cast of strangers at the gate; they want someone who will be there in three years if the front gate starts sagging again. That’s exactly how we work.
Foster City customers call us because we repair before we replace. If a hinge post has tilted, we reset it; if a weld has cracked, we weld it on site, in your driveway, not hauled off to some shop an hour away. Every job carries the 90-Day Done Right Promise, stamped in writing: if it’s not done right, one call brings Hal back. No fine print, no runaround. We’re licensed, insured, and bonded, and the license number is published for anyone to look up.
We answer the phone 24/7 with a live person. Not a voicemail, not a dispatch queue. If your community gate is stuck open at 2 a.m. on East Hillsdale Boulevard, you reach a human being who knows gates and can get help moving.
Our Gate Repair Services in Foster City
Hinge & Post Repair
In Foster City, the hinge post is where almost every repair starts. The reclaimed bay mud under this city never fully stops settling, so post footings shift and the post itself leans out of plumb. That pulls the gate down at the latch side and makes it bind. We reset posts into deeper, wider footings than the original 1970s or 1980s builds ever used, keyed below the lagoon mud line so the gate holds square for years, not seasons. A gate sags in the hinge post, not in the middle, and that is where we start.

Gate Realignment
Gate realignment in Foster City isn’t a one-time adjustment; it’s geometry and footings together. A gate that drags on the concrete usually means the post has rotated a few degrees, not that the panel suddenly bent. We realign the panel only after the post is set right, then check the latch, the hinges, and the operator limit settings so the whole system works as one. Fix the panel without the post and you’ll fix it twice. We see this constantly on the lagoon-fronting streets like Beach Park Boulevard and Edgewater Boulevard.

Electric Gate Repair
Foster City’s salt air is a genuine problem for electric gate systems. The operator’s circuit board sits inside a housing that breathes, and salt-laden air from the bay and the interior lagoons works its way in. We open the operator, inspect the board for corrosion, check the limit switches, and test the battery backup if there is one. We service Linear, Viking, DoorKing, and Ghost Controls operators, and we carry sealed connectors and coated fasteners meant for marine-adjacent jobs. This is not the same repair we’d write up in San Carlos or Belmont, where the air is dry and the operator internals stay clean for years.

Automatic Gate Repair
Automatic gates in Foster City fail in predictable ways: the safety edge corrodes, the photocell lens fogs from humidity, the rack and pinion jumps teeth when post settlement throws the track out of alignment. We test the full entrapment protection loop, replace sensors that have gone blind from condensation, and re-time the operator so the gate closes fully against the stop without slamming. If your community gate is a shared HOA entry, we know the pressure: residents want it working, and they want it working every time.

Trusted Brands We Service in Foster City
We service nine major gate brands, certified on all of them: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For Foster City specifically, we keep Linear and Viking parts on the truck most weeks, because those are the operators we see most often in the 1970s and 1980s HOA communities here. DoorKing slide operators show up on the larger community entries along the lagoon network. Because we stock parts for these brands, turnaround is faster; we don’t have to order a limit switch from a warehouse in Texas while your gate sits open.
Common Gate Repair Problems We See in Foster City Homes
- Posts tilting out of plumb because of bay mud settlement. Foster City sits on reclaimed tidal mudflats, and that substrate never fully consolidates. Hinge posts lean, swing gates bind at the latch side, and homeowners get a gate that won’t close all the way every couple of years unless the footing was built for it.
- Salt air eating hinges, welds, and operator boards. Foster City is surrounded by the bay on three sides, and the brackish lagoon air adds another layer of moisture. We replace hinge pins with stainless or coated hardware and inspect operator boards for the green corrosion that a year of marine air leaves behind.
- Rack and pinion slide gates jumping teeth. When post movement or rust throws the track out of alignment, the gear hits the rack at the wrong angle. The gate shudders, jumps a tooth, and the HOA entry ends up stuck open. The fix is realignment at the post level, not just tightening the rack bolts.
- HOA shared gates with failing access control. Many Foster City communities run a single shared gate with keypads, remotes, or a call box. When the operator fails, every resident notices. We work with property managers and HOA boards to keep the gate moving while approval paperwork for any permanent replacement is being finalized.

FAQs - Gate Repair in Foster City
Yes, in most Foster City communities, you will need HOA approval before a full gate replacement or any change to height, style, or finish. Foster City’s residential stock is almost entirely HOA-governed townhomes, condominiums, and planned single-family communities built between the 1970s and 1990s, and most HOAs have architectural guidelines that cover gates. Repair work that restores the existing gate to its original condition typically does not need approval, but replacement often does. We coordinate with property managers and boards so the work doesn’t stall on a form. Call (877) 610-2993 and we’ll walk you through what your specific HOA is likely to ask for.
The reclaimed bay mud under Foster City never fully consolidates, so a post set in a standard concrete footing can heave or tilt within a couple of years, especially on lagoon-fronting properties. The fix is a footing keyed below the lagoon mud line, with the post set in an engineered base that accounts for ongoing settlement. A standard repair won’t hold in this soil; you need a footing built for Foster City’s ground, not for a hillside lot in Belmont. Call (877) 610-2993 for an exact assessment of your post and footing.
The answer is sealed hardware, coated fasteners, and a maintenance schedule that includes opening the operator housing and checking the board for corrosion before it fails. Foster City’s marine layer and direct salt air from the bay and the lagoons will eat standard hardware within a year. We specify stainless or coated hinge pins, sealed connectors, and operator enclosures that breathe but don’t ingest salt. We also recommend a twice-a-year inspection for shared HOA gates, because a gate that serves twenty homes fails harder when it fails. Call (877) 610-2993 to set up a service schedule for your community entry.
Almost always, yes. A sagging gate is usually a post problem, not a panel problem. We repair the hinge post and realign the gate in your driveway; we don’t haul it off and sell you a new one unless the panel itself is structurally gone from rust. That repair-first approach is the whole reason we carry welding gear on the truck. The 90-Day Done Right Promise covers the work in writing. Call (877) 610-2993 and we’ll take a look before anyone talks replacement.
Yes. Automatic gates in California must have entrapment protection: a safety edge, a photocell, or an equivalent reversing mechanism, and it has to work. Foster City’s humidity and salt air corrode safety edges and fog photocell lenses faster than inland cities, so we test the entire entrapment loop on every automatic gate repair, not just the operator. If your community gate doesn’t reverse when it hits a person or a vehicle, it’s not just non-compliant, it’s dangerous. Call (877) 610-2993 and we’ll inspect the gate and the protection system.
