AfterFast, Reliable Electric Gate Repair Across San Lorenzo
Electric gate repair in San Lorenzo typically runs $185 – $420 for common failures like a dead opener, a rusted hinge post, or a control board shorted by marine moisture. Most repairs are completed same-day because we keep corrosion-resistant hardware and operator parts stocked for the Bohannon-era gates that dominate this community. If your gate won’t open, sags against the post, or makes a grinding sound when it cycles, call (828) 426-7081 and we’ll have a named, photo-badged technician at your door, usually within a few hours.
San Lorenzo isn’t like the inland East Bay. The bay-margin air here carries salt and persistent damp that attacks steel gate hardware in ways Castro Valley or Livermore simply don’t see. Add in the fact that nearly every home here was built between 1944 and 1955, and you get a neighborhood where thousands of original gates are aging out at the same moment. We know exactly what fails first and what actually lasts on the coast, because we work on these gates every week.
Why Warden Gate Repair Is San Lorenzo’s Preferred Electric Gate Repair Company
People in San Lorenzo tend to be careful about who they let through the gate. That’s the whole point of the thing. So we built our entire process around removing the two anxieties that come with hiring a repair company: not knowing who’s showing up, and not knowing what it will cost. Before any tech arrives, you get their name and photo sent to your phone. At your door, they show a photo ID badge. And before any work starts, you get a written price. Not an estimate range. A number. In writing. That’s what we call the Threshold Standard, and it’s enforced on every single visit.
Warden Gate Repair is an independently owned and operated location within the Threshold Group family. Cole Rafferty leads the team. We’ve specialized exclusively in gate repair and gate motor repair since 2008, and every job carries the 365-Day Done Right Promise: if the repair isn’t right, we come back and make it right, free. The second visit is included in the original price, always.
We answer the phone with a live person 24 hours a day, seven days a week. No voicemail tree when you’re standing in your driveway at 9pm with a gate that won’t close. You call, a person picks up, and we start figuring out what’s wrong.
Gate Access Control in San Lorenzo
Gate Access Control in San Lorenzo means the full system that decides who gets in: the keypad at the curb, the remote in your car, the intercom if you have one, the safety sensors, and the control board that ties it all to the operator. When any one piece fails, the whole experience falls apart. You’re stuck using the pedestrian gate, or you’re buzzing people in manually, or the gate simply won’t respond at all.
Most San Lorenzo access control failures we see are corrosion-related. The bay air gets into terminal blocks and circuit boards, especially on equipment installed before sealed outdoor enclosures became standard. A keypad that worked fine in July starts typing double-digits by February. A remote that used to reach from the street now needs you to be five feet away. These are fixable problems, but they need someone who understands coastal electronics, not someone who swaps parts by guesswork.
Keypad and Remote Repair
A keypad on a San Lorenzo gate is exposed to everything: winter rain, summer marine fog, direct afternoon sun. We replace failed keypads with weather-sealed units and re-terminate the wiring with stainless or tinned connectors so the next failure is years away, not months. Remotes are simpler: when one dies, we match the exact frequency and rolling code format for your operator brand, sync it on-site, and test it from both sides of the gate.
Control Board Replacement
Control boards are the brain of the system, and they’re the most vulnerable component in a salt-air environment. We carry replacement boards for FAAC, BFT, and Linear operators specifically because those three brands are heavily represented in San Lorenzo’s original and early-upgrade gate installations. A typical control board replacement in San Lorenzo runs $240 – $390 installed, depending on the operator model and board version.
Commercial Gate Operator in San Lorenzo
A Commercial Gate Operator in San Lorenzo is a heavier-duty unit than residential equipment, designed for slide gates or wide swing gates that cycle dozens or hundreds of times a day. San Lorenzo has a surprising number of these: the small industrial buildings along Grant Avenue, the multi-unit properties near Hesperian Boulevard, and the churches and schools that anchor the older village core. When one of these operators fails, it’s not just an inconvenience. It stops deliveries, blocks tenant access, and leaves the property unsecured.
We repair and replace commercial operators from FAAC, BFT, Viking, and Linear, and we’re factory-trained on all of them. Commercial work is scheduled, not dispatched same-day. We come out, measure the gate, assess the operator, and give you a written replacement or repair price before anything is ordered. Typical commercial gate operator repair in San Lorenzo runs $380 – $900 depending on whether we’re replacing a limit switch or the entire drive unit. Full operator replacement on a commercial slide gate usually lands between $2,800 and $5,500 installed.
Slide Gate Repair
Slide gates are common on San Lorenzo commercial properties because they need less clearance than a swinging leaf. The weak points are the rack and pinion drive, the guide rollers, and the motor. When the clay soil near the bay saturates in winter, the concrete track bed can shift just enough to bind the gate and burn out the motor. We re-level the track, replace worn rollers, and repair or replace the drive motor with a unit rated for continuous use.
Swing Gate Operator Repair
Swing gate operators fail differently here. The hydraulic or electromechanical arm wears out from working against hinges that are corroding and binding. We fix the hinge first, then address the operator, because replacing the motor on a gate that still drags is just paying for the same repair twice. It’s the kind of sequencing you learn from working on hundreds of these gates in San Lorenzo’s specific conditions.
Trusted Brands We Service in San Lorenzo
We’re authorized to service and repair equipment from LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For San Lorenzo specifically, we keep a working stock of FAAC, BFT, and Linear parts on hand because those are the brands most commonly found on the original and upgrade installations in this city’s housing stock. That means fewer waiting days for parts and more repairs finished in a single visit. When a control board or limit switch from one of these brands fails, we usually have the replacement on the truck when we arrive.
Common Electric Gate Repair Problems We See in San Lorenzo Homes
- Hinge posts corroded at the base. The bay-margin salt air attacks steel at the soil line, where moisture sits longest. The post rusts through, the gate sags, and the operator starts binding against the misalignment. We replace the post with galvanized steel and upgrade to stainless hinges.
- Control boards failing from marine moisture. Persistent damp creeps into unsealed enclosures and corrodes terminal connections and circuit traces. The gate stops responding to remotes, or it cycles on its own at 2am. We replace the board and seal the enclosure properly.
- Posts heaving out of plumb after winter rains. San Lorenzo’s clay-heavy soil absorbs winter rain, expands, and shifts gate posts. A gate that was perfectly aligned in October scrapes the ground by January. We re-set the post in concrete with proper drainage and re-align the rack and pinion.
- Weld failures on original 1950s gate frames. The original Bohannon-era gates were often welded from mild steel with no corrosion protection inside the tubing. After 70 years of bay air, the welds at corners and hinge mounts crack. We grind out the failed weld and re-weld, then treat and seal the joint.

FAQs About Electric Gate Repair in San Lorenzo
San Lorenzo sits close to the bay margin and San Lorenzo Creek, which means persistent marine moisture and salt in the air that Castro Valley and Livermore don’t get. The salt accelerates corrosion on steel hinges, posts, and operator enclosures, especially at the soil line where water pools. A galvanized post that would last 40 years in Livermore might fail in 25 here if it wasn’t protected properly at installation. We recommend galvanized posts, stainless hinges, and sealed operator enclosures for any San Lorenzo installation. Call (828) 426-7081 for an assessment of what you currently have.
If your property falls under the San Lorenzo Village Homes Association deed restrictions, you may need design approval for a gate replacement that changes the style or materials of the original. Replacing the operator itself, the motor and control unit, usually doesn’t trigger review because it’s not visible from the street. But if you’re replacing the gate leaf or posts, the SLVHA can require that the new materials match the original look. We can provide material and style documentation for your SLVHA submission on any job.
The failure is almost always at the hinge post base. San Lorenzo’s clay soil expands when saturated, shifting the post out of plumb. Meanwhile the post may have been rusting at the soil line for years. The combination means the gate drops, the latch misses, and the operator starts laboring. The fix is setting a new galvanized post in concrete with a proper drainage path, then switching to stainless hinge hardware. That addresses both the sag and the rust in one repair.
We service LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. San Lorenzo has a high concentration of FAAC, BFT, and Linear units on the original and early-upgrade gates, so we keep those parts stocked locally. We’re factory-trained across all nine brands, which means the right parts and the right knowledge arrive together on the first visit. Call (828) 426-7081 and tell us your brand and model; we’ll confirm we have what’s needed.
For San Lorenzo’s bay-margin conditions, we recommend galvanized steel posts, stainless steel hinges and fasteners, and operator enclosures rated for outdoor coastal exposure. Painted mild steel is the worst choice here, it looks fine for a year and then starts rusting at every scratch and edge. If you’re replacing an original Bohannon-era gate, we can match the original style in a galvanized or stainless build that satisfies SLVHA requirements and actually lasts. Want a specific recommendation for your gate? Call (828) 426-7081 and we’ll walk the property with you.
