AfterTrusted Gate Repair for San Mateo Homeowners
Gate repair in San Mateo typically costs $180-$890 depending on the problem, and most calls are completed the same day we arrive. A stuck swing gate, a grinding slide motor, or a rusted hinge on a fog-exposed coastal property - we’ve documented and fixed all of them under The Haven Standard since 2014.
We’re Vance Gate Repair, independently owned and operated by Adrian Vance out of commercial access-control work that started in 2014. Our San Mateo technicians carry OEM parts for nine automation brands and leave every job with a written record, photographed evidence, and a 365-Day Done Right Promise. If your gate is stuck open, stuck closed, or making noises it didn’t make last month, call (650) 293-9440. A live person answers 24 hours a day, and we’ll have a flat, written price in your hands before any work begins.
What Our Gate Repair Service Includes
Electric Gate Repair
Electric Gate Repair in San Mateo addresses failures when power delivery, control boards, or safety circuits break down - often after moisture intrusion from our marine layer mornings. We trace the fault with a multimeter and load tester, then photograph every terminal block and ground connection before we leave. Last month in the Baywood neighborhood, we found a DoorKing control board with corroded relay contacts from salt air; we replaced the board, sealed the enclosure with a gasket upgrade, and logged the part serial number in the homeowner’s file.
Automatic Gate Repair
Automatic Gate Repair depends on limit switches, photo eyes, and motor encoders working in sequence. When any one fails, the gate reverses randomly, stops mid-travel, or refuses the remote entirely. We carry diagnostic tools for Viking, Ghost Controls, and Elite systems, and we stock the most common limit-switch assemblies for same-day resolution. In San Mateo’s older Laurelwood builds, we regularly see photo eyes knocked two inches out of alignment by landscaping crews; we realign, test the obstruction response ten times, and photograph the final beam path.
Hinge & Post Repair
A sagging gate almost always traces to a failing hinge, a cracked post footing, or both - issues we address with our Hinge & Post Repair service. In San Mateo’s hillside neighborhoods like Sugarloaf and Baywood Knolls, gate posts settle differentially as soil shifts through wet winters, and the resulting bind tears hinge barrels apart. We cut out the failed hardware, re-plumb the post with structural grout or replace it entirely, and install greaseable ball-bearing hinges rated for the gate’s actual weight - not what the original installer guessed.
Gate Realignment
Gate Realignment fixes gates that drag on the driveway, scrape the catch post, or no longer latch cleanly. The cause is usually post movement, hinge wear, or track distortion on slide gates. We measure the opening diagonally, check plumb with a laser level, and adjust or replace components until the gate’s travel path is true. For a recent job near San Mateo Central Park, we found a slide gate track bowed 3/8 inch from a delivery truck impact; we pulled the track, re-anchored it to a reinforced embed, and verified smooth travel across the full 18-foot run.
Lock Repair
Gate locks fail from corrosion, forced entry attempts, or internal mechanism wear. We repair or replace magnetic locks, electric strikes, mechanical deadbolts, and keypad-controlled latches. In San Mateo’s fog belt near the bay, we see stainless-steel lock bodies that look fine externally but have frozen internal pawts from moisture migration. We disassemble, clean, lubricate with dielectric grease, or replace with marine-grade hardware - and we document the keyway code or keypad program in your file for future reference.
Weld & Rust Repair
Steel gates in San Mateo’s climate develop rust at weld joints, lower frame members, and anywhere the powder coat has chipped. We grind to bright metal, weld in patch plates or replacement pickets as needed, and apply a zinc-rich primer followed by color-matched topcoat. For a gate near 20th Avenue last spring, we cut out a rusted 14-inch lower rail, fabricated a replacement from 14-gauge steel, welded it with ER70S-6 wire, and left the homeowner with a photo of the weld penetration and the paint code used.

Brands We Service for Gate Repair
We service and stock parts for nine major gate automation brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Our Viking experience runs deep - we’ve repaired hundreds of Viking swing and slide operators across the Peninsula, and we keep their G-5 and L-3 control boards, limit-switch kits, and arm assemblies on our San Mateo trucks. Ghost Controls systems are common on residential driveway gates in the Hillsborough and Belmont areas; we stock their torsion-spring hardware and control-box replacements, and we know the programming sequence for their auto-close and party-mode features without consulting the manual.
DoorKing remains the workhorse of commercial and multi-family properties from downtown San Mateo to the industrial corridor near Highway 101. We carry their 9100 and 9150 operator parts, their loop-detector boards, and their telephone-entry accessories. Elite operators show up frequently on older estate properties; we service their CSW and SL-3000 series and can source obsolete control boards through our commercial supply network. Whether you have one of these brands or any other make, we can diagnose it, repair it, and document what we did.
BeforeAfterSigns You Need Gate Repair Right Now
- The gate reverses before closing fully. This usually means a photo eye is misaligned, a limit switch is drifting, or there’s an obstruction in the track. It’s not a quirk to live with - it’s a safety system crying for attention, and in San Mateo’s dense neighborhoods, a gate stuck open is a liability.
- You hear grinding, squealing, or clicking that wasn’t there last month. New noises mean mechanical wear: a dry gear rack, a failing motor bearing, or a loose chain drive. Catching it now often means a $200 adjustment; waiting means a $900 motor replacement.
- The remote works intermittently or only from certain angles. This points to a failing receiver, antenna damage, or low signal strength from the transmitter. We test signal strength in millivolts and replace receivers with the correct frequency-matched unit.
- The gate sags, drags, or requires a shoulder push to latch. Hinge wear, post settlement, or track distortion is progressing. Every forced closure damages something else - the latch, the operator arm, or the post footing.
- There’s visible rust at welds, joints, or the lower frame. San Mateo’s marine layer accelerates corrosion where paint has failed. Surface rust becomes structural rot faster than most homeowners expect, especially on gates within a mile of the bay.
Our Gate Repair Process - Step by Step
- 1
Call and describe what you’re seeing. A live person answers at (650) 293-9440, 24 hours a day. We ask about the gate type, the brand if you know it, the symptoms, and whether the gate is currently stuck open or closed. This lets us dispatch the right technician with the right parts.
- 2
On-site diagnosis with documented findings. Our technician arrives in a marked vehicle, uniformed, with name and photo already texted to you. We inspect the operator, mechanical hardware, electrical connections, and safety systems. Every finding is photographed - the worn hinge, the corroded terminal, the misaligned photo eye - and noted on a tablet.
- 3
Written price before any work starts. Under Haven Standard Clause 1, you receive a flat, itemized price in writing before we pick up a tool. No hourly rates, no “plus materials” surprises. You approve the scope, or you don’t - no charge for the diagnosis either way.
- 4
Repair with photographic evidence. We complete the approved work, test all functions ten cycles minimum, and photograph every adjustment, replacement, and final setting. The limit-switch position, the photo-eye alignment, the torque setting on the arm - it’s all in your record.
- 5
Documentation delivered, promise activated. Before we leave, you get a printed or emailed photo log of the visit and a written summary of parts installed and settings adjusted. The 365-Day Done Right Promise covers everything we touched. If it isn’t right, we make it right - no argument, no fee, no expiration within that year.
How Much Does Gate Repair Cost in San Mateo?
Gate repair pricing in San Mateo depends on the gate type, the failure mode, and whether OEM parts are still available for your automation brand. Here are the ranges we see most often:
| Repair Type | Typical Range in San Mateo | What Affects Price |
|---|---|---|
| Photo eye realignment or replacement | $180 - $290 | Number of eyes, conduit run length, brand |
| Limit switch adjustment or replacement | $220 - $340 | Accessibility, operator brand, dual vs. single gate |
| Hinge replacement (per hinge) | $240 - $420 | Gate weight, post condition, ball-bearing vs. bushing |
| Control board replacement | $380 - $720 | Brand availability, enclosure condition, programming complexity |
| Motor / operator repair | $450 - $890 | Slide vs. swing, brand, gear reduction type |
| Weld and rust repair (per section) | $320 - $680 | Material thickness, paint match requirement, structural vs. cosmetic |
What moves a job toward the higher end: obsolete parts requiring special order, hillside access requiring portable welding equipment, or multiple concurrent failures (a common scenario when a gate has been forced manually after an operator failure). What keeps cost down: catching problems early, having your gate brand and model visible, and clearing vegetation or storage items from the gate area before we arrive.

Frequently Asked Questions - Gate Repair in San Mateo
Gate repair fixes the operating system, mechanical hardware, or structural elements of an existing gate without installing a new gate leaf or frame. You need repair when the gate itself is sound but something in its movement, control, or security has failed - a motor that won’t run, a hinge that sags, a lock that won’t release. Replacement makes sense when the gate frame is rotted, the design no longer meets your needs, or repair costs exceed 60% of a new installed gate. We diagnose first and recommend honestly; our flat-price estimate shows both options when they’re close.
Most residential gate repairs in San Mateo are completed in 1.5 to 3 hours on-site. Photo eye realignments, limit-switch adjustments, and single-hinge replacements often run under 90 minutes. Control board replacements, motor rebuilds, or weld repairs with paint cure time can extend to half a day. We schedule with a two-hour arrival window and text when the technician is en route. Call (650) 293-9440 to check same-day availability - most standard repairs are dispatched within hours.
Electric gate repair in San Mateo typically runs $220-$720 for control and safety-system issues, and $450-$890 when the motor or gearbox needs work. The brand matters significantly - a LiftMaster or FAAC part is usually in stock, while an obsolete Elite or early Mighty Mule board may need sourcing. We always provide a written, flat price before starting, and our free estimates include a full electrical diagnosis. Call (650) 293-9440 for an exact quote on your specific system.
Yes - we service all three brands regularly and stock common parts for each. Viking operators are common on commercial and heavy residential gates in San Mateo; we carry their control boards, limit switches, and arm assemblies. Ghost Controls systems appear frequently on newer residential installations in the Peninsula hills; we stock their hardware and know their programming sequences. Elite units, often found on estate properties from the 2000s, are supported through our commercial supply network even when parts are officially obsolete. Whatever brand is on your property, we can work on it.
Yes - a live person answers our phones 24 hours a day, seven days a week, and we dispatch for security-compromising emergencies including gates stuck open, gates blocking vehicle egress, and access-control failures at multi-family properties. After-hours calls carry our standard diagnostic and labor rates; we do not surcharge for nights or weekends. The 365-Day Done Right Promise applies to all emergency repairs exactly as it does to scheduled work. If your gate is stuck open and you cannot secure your property, call (650) 293-9440 now.
Every repair is covered by our 365-Day Done Right Promise: if anything we repaired fails within one year due to workmanship or the specific part we installed, we return and make it right at no charge. This is not a pro-rated or limited warranty - it’s a full-year, no-argument commitment under Haven Standard Clause 3. Parts carry their manufacturer’s warranty in addition; if an OEM board fails at 14 months, we handle the manufacturer claim and charge only for labor if the part is replaced.
Clear a path to the gate operator and both sides of the gate leaf; move vehicles, storage bins, or dense vegetation that blocks access. If you know the gate brand and model, have that ready - it’s usually on a label inside the operator cover. For electrical issues, verify that the breaker hasn’t tripped; if it has, note whether it trips again when you reset it. You do not need to be present for the entire visit if you provide access, but we do need someone available to approve the written price before work begins under Clause 1. Call (650) 293-9440 to schedule - estimates are free and no-obligation.
