Why Gatewood Fence & Gate Is Millbrae’s Preferred Gate Repair Company
Hal Gatewood started this shop in 2001, and his name has been on the door ever since. That matters in Millbrae, where most of the gates we see were hung when Eisenhower was president and the hardware has now outlived two or three openers. We don’t send a salesperson to write a quote. Hal or one of his crew shows up, puts eyes on the hinge post first, and tells you honestly whether the gate can be saved or whether you’re paying good money to patch a post that’ll fail again by spring.
Millbrae homeowners tend to be skeptical of big promises. That’s fair. We’ve done enough work on Hillcrest Drive, Taylor Boulevard, and the side streets off Magnolia Avenue to know that a gate sagging at the latch isn’t a panel problem, it’s a post-root problem. The person who shows up at your door has done this trade for years, carries a welder in the truck, and answers to Hal directly. If you want to look somebody in the eye before you sign anything, the shop address is published and you’re welcome to come by.
Calls are answered by a live person 24 hours a day, every day. Not a dispatch queue, not a call center in another state. If your gate won’t close at 11:30 at night and your driveway faces the street, you’ll talk to someone who understands why that’s urgent.
Our Gate Repair Services in Millbrae
Electric Gate Repair
Electric gate repair in Millbrae usually means one of three things: a control board that’s lost its mind, a motor that’s overloaded, or a limit switch that’s drifted out of calibration. Around here there’s a fourth factor: SFO. The constant low-frequency vibration from departures overhead works its way into FAAC and LiftMaster boards and rattles limit-switch settings loose over time. We recalibrate the travel, re-seat the board, and test the gate through twenty full cycles before we call it done. If a safety photo-eye has failed or the loop detector isn’t picking up a car on the apron, we fix that on the same call rather than telling you to wait for a “second visit.”

Automatic Gate Repair
Automatic gates on Millbrae’s steeper driveways run into a problem that flatter neighborhoods never see: rollback creep. A Viking or BFT operator on a 12-percent grade works against gravity every time it closes. When the motor starts overload-tripping, the cause is often a combination of worn gear drive, a gate that’s picked up half an inch of sag, and limit switches knocked out of calibration by vibration. We check the full mechanical chain, not just the electrical box. Sometimes the fix is a recalibration. Sometimes it’s a new drive arm and new hinges so the motor stops fighting the gate.

Hinge & Post Repair
This is the repair that saves the most money long-term, because it addresses where gates actually fail. A 1950s wrought-iron gate in Millbrae usually doesn’t break in the middle. It fails at the bottom hinge, where sixty years of coastal humidity and ground moisture have thinned the tubing, or at the post base, where anchor bolts have worked loose from decades of vibration. Hal’s crew welds on site, in your driveway, so the gate never leaves the property. We cut out the rusted section, sleeve or replace the bottom rail, re-anchor the post with new bolts and epoxy, and paint the repair to match. If the post itself is rotted through at the footing, we say so plainly, because welding a sound panel to a dead post is throwing money away.

Gate Realignment
A gate that drags on the driveway or won’t latch isn’t necessarily broken. It’s usually settled. In Millbrae, where the soil shifts with wet winters and dry summers, gate posts creep out of plumb over decades. We realign the hinges, shim the post if the foundation is sound, and reset the latch so it catches without slamming. When an automatic gate is involved, realignment also means resetting the opener’s travel limits so the motor isn’t slamming the gate into the stop every cycle. On hillside properties west of El Camino Real, a gate that’s out of plumb by even half an inch makes the opener work twice as hard. Realignment is often the cheapest fix we can make with the biggest effect on motor life.

Trusted Brands We Service in Millbrae
We’re certified to service nine major gate brands, including FAAC, BFT, Linear, and Viking, plus LiftMaster, Ghost Controls, DoorKing, Elite, and Mighty Mule. We keep common boards, limit switches, photo-eyes, and actuator arms in the truck so we’re not driving back to the shop for parts mid-job. That matters in Millbrae, where a gate that won’t close on a street-facing driveway means a car left out overnight. If your opener is a legacy unit that the manufacturer stopped supporting eight years ago, we’ll tell you plainly whether a retrofit board is worth it or whether you’re better off replacing the unit. We don’t get attached to repairing something that’s going to cost you more in the long run than a new motor.
Common Gate Repair Problems We See in Millbrae Homes
- Vibration-loosened hinge bolts: Millbrae sits directly under SFO’s primary departure and arrival corridors. The low-frequency rumble works through the ground and into gate posts, loosening anchor bolts a fraction of a turn at a time. After enough cycles, the gate sags, starts dragging, and then the opener motor overloads trying to move it.
- Opener limit-switch drift: Those same vibrations rattle the limit-switch settings inside the control board. Your gate suddenly stops a foot short of closed, or reverses halfway through its travel, and the problem isn’t the motor-it’s the calibration. We see this constantly in the 94030 neighborhoods around Green Hills and the streets near Central Park.
- Rust at the post base: The marine layer off the Bay keeps Millbrae’s humidity high, and the bay-facing side of town gets enough salt air to pit iron and steel faster than you’d expect. Rust never starts where you can see it from the driver’s seat; it starts underground, where the post meets the footing, in the dampest, least-painted part of the install. By the time you see pitting above grade, the metal below is often significantly thinner.
- Legacy openers with no safety edge: A lot of the original openers on Millbrae’s 1950s and 1960s homes were installed before modern safety requirements existed. No photocell across the apron, no reversing edge. They still work, but if a car or a kid is in the gate’s path, the gate doesn’t know. We retrofit photo-eyes and pressure-edge systems onto older openers whenever possible. If the opener is too far gone, we tell you that too.
Pricing for Gate Repair in Millbrae, CA
Here’s what gate repair actually costs in Millbrae, based on the jobs we do most often:
- Hinge & post repair: $180-$340 typical, including on-site welding and paint match.
- Gate realignment: $150-$280, depending on post condition and opener reset.

What pushes a job to the higher end: a post that has rotted through below grade, a gate that’s been welded once before by somebody who didn’t fix the underlying alignment, or an opener so old that every part is now obsolete. We quote the job in writing before any work starts. The number we quote is the number on the invoice. No trip charge inside the county, $40 off any repair over $200, and a standing 10% discount for seniors and veterans. If another company quoted you something else, bring us the written estimate and we’ll give you a free second opinion.
One note on repairs worth doing versus repairs that are math problems: if a gate is rusted through at three of four hinge points, has a post that looks like barnacle at the base, and the panel has been patched twice, we’ll tell you honestly that replacement is cheaper over five years. Hal would rather lose a repair sale than take your money knowing it’s coming back to haunt him. That’s what having your name on the shop means.

FAQs - Gate Repair in Millbrae
The culprit is almost always SFO jet vibration. Low-altitude departures and arrivals send low-frequency vibration through the soil and into your gate posts, and hinge bolts work loose a fraction of a turn at a time. Once they’re loose, the gate starts sagging, and then the opener motor takes on extra load. The proper fix is to re-anchor the hinge bolts with thread-locking compound and verify the post is still solid, not just tighten the bolts for the fourth time. Call (877) 610-2993 and we’ll do it properly.
It depends entirely on the post and the bottom rail. If the post is still structurally sound and the rust is confined to the lower hinge area, a good on-site weld repair will buy you another fifteen or twenty years, and it’ll cost less than half of a new gate. If the post has rotted below grade or the bottom rail is thin enough to dimple with light hammer tap, replacement is the honest answer. We’ll show you the problem and let you decide. Estimates are free.
The grade wasn’t factored into the original install, and your opener has been fighting gravity every day since. As the gate gains a little sag, the motor pulls more amps, and then it trips. Add SFO vibration knocking the limit switches out of calibration, and the motor doesn’t even know when to stop pulling. The fix is usually a combination of gate realignment, travel-limit recalibration, and sometimes a heavier-duty actuator arm. We see this consistently on the hillside streets like Hillcrest Drive and Murchison Drive. Call us for a free look.
Yes, in most cases. We retrofit photo-eye beams and pressure-sensing edges onto legacy openers all the time in Millbrae. The control board needs to support reversing logic, and some 1950s-era boards don’t, in which case we can often add a retrofit safety module without replacing the whole opener. If the opener is beyond retrofitting, we’ll tell you straight, and we’ll show you what a modern replacement costs. (877) 610-2993 for a no-obligation assessment.
Salt-laden air from the Bay combined with Millbrae’s high humidity concentrates at the post base, where condensation and ground moisture meet the least-painted part of the install. Bay-facing blocks get the worst of it. The rust usually starts below grade and works its way up, which is why we dig down a few inches around the post base on every rust repair in Millbrae rather than just wire-brushing the visible pitting. Catching it early means a $200 repair instead of a $1,200 post replacement.
We’ve done gate repair in Millbrae long enough to know this city’s gates better than most of the people who installed them. If yours won’t close, sags at the latch, or sounds like a coffee grinder when it moves, call (877) 610-2993. You’ll get a live person, a straight answer, and a written price before any work starts. Hal’s name is on the shop and on every invoice, and the 90-Day Done Right Promise means one call brings him back if something isn’t right.
