AfterFast, Reliable Gate Repair Across San Leandro
If your gate is dragging, jamming, or refusing to open in San Leandro, the most likely culprit isn’t the operator itself. It’s the ground under it. San Leandro sits directly on the Hayward Fault, and constant micro-movement shifts post footings, knocks rack and pinion gears out of alignment, and throws safety photocells off aim. We see it every week in neighborhoods like Estudillo Estates, Washington Manor, and Bonaire. Calder Gate Repair handles the full diagnosis and fix: we reset posts, re-level tracks, re-aim sensors, and only then address the operator. Call (903) 417-0793 and a real person answers, 24/7.
Why Calder Gate Repair Is San Leandro’s Preferred Gate Repair Company
Calder Gate Repair is the dedicated gate specialist inside the Relay Home Co. family, founded in 2009. Our San Leandro customers tell us the same thing again and again: they like knowing the price before we start, and they like the live arrival time on their phone. No four-hour windows. No mystery invoices. Every technician is background-checked and wears a uniform, and the written quote we hand you is the number you pay. If the repair doesn’t hold, the 365-Day Done Right Promise means we return free of charge. That’s not a sales line. It’s written on every job.
Being local matters here because San Leandro gates fail in ways that a general handyman won’t spot. The Hayward Fault changes how posts settle, how tracks shift, how gates hang. A technician who knows this city’s soil and foundation patterns diagnoses faster and fixes things properly the first time. We dispatch from the San Francisco Bay Area office and serve San Leandro neighborhoods directly, so response times stay tight and parts runs stay short. You can read more about how our Gate Repair process works, but the short version: you’ll get an honest diagnosis, a written price, and a repair backed in writing.
Wood Gate Repair in San Leandro
Wood Gate Repair in San Leandro isn’t just about swapping a few boards. The real work happens at the hinges and the post. San Leandro’s older housing stock includes a lot of redwood and cedar gates from the 1950s through the 1980s, and those gates are heavy. When the Hayward Fault shifts the footing, even a quarter inch, the gate starts to sag and drag. The hinge post leans. The latch stops lining up. The operator, if there is one, starts over-torquing and burning out. We re-set the posts, rebuild hinge mounts, straighten or replace warped rails, and then brace the gate properly so it hangs square again.
Most Wood Gate Repair work in San Leandro runs between $280 and $575, depending on post condition and how much of the frame needs attention. A full post replacement with new concrete footing typically adds $200 to $400 per post. This labor includes hauling away the old footing and letting the new one cure properly, which matters on shifting ground. We give the written number before we start, no exceptions.
Hinge & Post Reset
Loose hinge lag screws, leaning posts, and cracked concrete footings are the three most common wood gate failures we find in San Leandro. We excavate around the post, re-plumb it, pour a deeper footing when needed, and re-hang the gate so the weight transfers cleanly through the hinge to the post, not into the operator.
Wood Rot & Rail Replacement
San Leandro’s morning fog and damp winter air mean bottom rails rot faster than homeowners expect. We cut out rotted sections, sister in pressure-treated or cedar replacements, and treat the joints so moisture stops wicking upward. A well-repaired wooden gate should swing freely again without feeling like it has to be shoved.
Driveway Gate Repair in San Leandro
Driveway Gate Repair in San Leandro usually involves a slide gate that no longer aligns with its track, or a swing gate that grinds through its travel arc. The driveway gate is the one you rely on every single day, and it takes the most abuse: weather, daily cycles, kids, deliveries, and in this city, ground creep. We repair the full system, meaning the gate itself, the track or hinges, the operator, the safety edges, the photocells, and the control board, as one integrated unit. Not piecemeal patches.
Driveway gate repairs in San Leandro typically run $225 to $520 for mechanical alignment and component replacement. If we need to cut out and re-pour a track foundation or rebuild a post base, expect $400 to $800. Operators are a separate line item, and we tell you the brand and model price before ordering anything. Every quote is written and agreed before work begins.
Slide Track Realignment
Ground settlement under a concrete track is the quiet gate killer in San Leandro. The gate starts binding, the operator strains, and eventually the pinion gear strips against the rack. We re-level the track, replace worn rollers, re-shim the rack, and set the gear mesh to factory spec before testing the operator under load.
Swing Gate Operator Diagnostics
When a swing gate jerks, reverses, or refuses to open, people blame the motor. Often the motor is fine and the foundation has shifted. We check the post plumb, the hinge geometry, the force settings, and the safety sensor aim before touching the operator itself. That way you don’t pay to replace a part that wasn’t broken.
Trusted Brands We Service in San Leandro
Our technicians are factory-familiar with nine major gate opener brands, including Viking, Ghost Controls, and DoorKing. That means we diagnose and repair control board faults, gear wear, limit switch problems, and receiver issues without waiting on a third-party service rep. For San Leandro customers, we keep common parts for these brands in local stock: limit switches, control boards, remotes, safety edges, and photo eyes. That keeps turnaround fast. If your opener was installed by another company or bought online, we’ll still service it. Brand familiarity is about speed and accuracy, not about making you pay a premium.
Common Gate Repair Problems We See in San Leandro Homes
- Post footing drift from Hayward Fault creep. The gate doesn’t fail first. The ground moves, the post leans, and the gate binds. We see swing gates dragging by half an inch in as little as a few years after original installation.
- Rack and pinion misalignment on slide gates. When the track foundation settles, the rack moves out of mesh with the pinion gear. The gear teeth strip, and the operator burns out trying to push through the resistance. Alignment first, then engagement testing, then operator rebuild if needed.
- Safety photocell and loop detector faults after fence or landscaping work. A neighbor replaces a fence post. A gardener re-runs a sprinkler line. The photo eye gets bumped half an inch. Now the gate reverses randomly and everyone blames the motor. We re-aim and re-test before recommending any replacement.
- Operator over-torquing from dragging gates. A gate that scrapes or binds makes the operator pull more amps than it was designed for. This shortens motor life, overheats the control board, and trips the thermal cutout. Fix the mechanical drag first, then let the motor run clean.

FAQs About Gate Repair in San Leandro
In most cases it’s a photocell alignment problem, not a bad motor. The Hayward Fault’s constant micro-movement shifts posts and mounting brackets, which throws the safety photo eyes out of aim. The gate thinks something is blocking the path and reverses. We re-aim or replace the sensors and test the gate under actual travel conditions. Call (903) 417-0793 and we’ll talk you through what to check before we come out.
Most sagging wooden gates in San Leandro can be repaired rather than replaced. The problem is usually the hinge post footing shifting, not the gate frame failing. We re-plumb the post, re-set the footing, and re-hang the gate. If the bottom rail is rotten, we replace that rail while we’re there. Full replacement makes sense only when the entire frame is compromised beyond structural integrity. We’ll show you the difference on site and give you a written price for either option before any work starts.
We service Viking, Ghost Controls, and DoorKing, along with LiftMaster, FAAC, BFT, Linear, Elite, and Mighty Mule. Our technicians train across all nine brands, so control board diagnostics, limit adjustments, and receiver programming don’t involve a learning curve on your gate. We stock common parts for these brands locally, which means fewer return trips to the shop and faster completion on most San Leandro jobs.
Most mechanical gate repairs in San Leandro finish in 90 minutes to 3 hours on site. Post re-setting or footing replacement adds cure time, which we account for in the schedule. We prioritize returning your gate to working order the same day whenever the repair allows, but we never rush a footing or an alignment to hit a clock. The written quote includes the full time estimate before we begin.
Yes. Automatic gates in California are required to have functioning safety devices: photo eyes, safety edges, or both, depending on the installation. A gate that reverses on contact or has misaligned sensors is a liability and a safety risk. We test every sensor as part of the repair and we retest reversal force with a physical obstruction before we call the job finished. If your sensors keep triggering falsely, call (903) 417-0793 and we’ll diagnose the aim and alignment properly.
