Why Calder Gate Repair San Jose Is Atherton’s Preferred Electric Gate Repair Company
Atherton homeowners call us because we treat a gate repair the way the property demands: precisely, quietly, and with a written price before the first tool comes out. Our techs have worked on estates off Walsh Road, around Lloyden Drive, and up along the Polhemus corridor, so we know what it takes to service a heavy bespoke gate without leaving a mess or a mismatched hinge. We’re part of the Relay Home Co. family, established 2009, and every job carries the 365-Day Done Right Promise: if the repair fails within a year, Calder returns at no charge. That’s in writing, on every invoice.

Styles & brands we work with





Commercial Gate Operator in Atherton
A Commercial Gate Operator is the motor-and-drive unit that moves a heavy vehicle gate, and in Atherton this often means a hydraulic or commercial-grade operator on a custom steel or wrought iron gate that weighs several hundred pounds. Homeowners here aren’t running big-box residential openers on these gates; they’re running FAAC hydraulic rams, BFT linear actuators, or Viking swing operators sized for estate entrances. When one of these fails, the gate either won’t move, moves in jerks, or trips its own safety stop.
Underground and Hydraulic Systems
Atherton estates frequently have underground operators hidden beneath the gate hinge line so nothing disrupts the sightline. These are maintenance-heavy: dirt intrusion, water ingress after winter rain, and hydraulic fluid leaks are the three failures we see most. We pull the ram, flush the fluid, reseat the seals, and re-bed the mounting plate so the gate doesn’t tilt as it cycles.
Commercial Board and Control Wiring
When a commercial operator loses its control board, the gate’s brain is gone. In Atherton, many of these boards tie into camera systems and intercoms at the property edge, far from the house. We run new low-voltage lines when the old cable’s degraded, re-terminate the board connections, and load-test the system before we leave. A commercial gate board replacement in Atherton typically runs $450 – $1,100 including labor, before any specialized board cost.
Automatic Gate Repair in Atherton
Automatic Gate Repair in Atherton covers the full automated entry system: the opener, the safety sensors, the keypad, the remote receivers, and the intercom. Most calls start with “the gate won’t open” and end with a failed limit switch, a misaligned photocell, or a receiver that’s lost its programming. On an Atherton estate, these components are often spread across a long driveway: keypad at the road, opener by the gate, intercom on a post 80 feet away. A bad splice in the middle of that run mimics a dead opener.
Keypad and Intercom Sync
Atherton properties commonly have a matched pedestrian gate next to the main vehicle gate, and homeowners want one code to open both. That’s a programming and relay job, not just a keypad swap. We wire the second relay, set the delay so the vehicle gate doesn’t fight the pedestrian gate, and test both from the street and from the house side. This sync job, where both gates operate from a single entry code, is something we handle frequently in Atherton and rarely in surrounding towns.
Sensor and Photocell Alignment
Safety photocells are the small beam sensors mounted low on the gate posts. If they misalign, the gate refuses to close, or worse, reverses mid-cycle. On Atherton’s heavy custom gates, the cause is often a shifted hinge post, not a sensor that simply “went bad.” We level the gate first, then align the sensor, then cycle the gate ten times to confirm the entrapment protection responds correctly every time.
Trusted Brands We Service in Atherton
Calder Gate Repair San Jose technicians are factory-familiar with nine leading opener brands, and in Atherton the most common calls we get are for FAAC hydraulic operators on estate entries, BFT control boards on newer installs, and Linear receivers on gates that predate the last remodel. We stock local parts in our Bay Area service vehicles for these three brands specifically, along with common Viking capacitors and photo eyes, which means many Atherton repairs happen the same day without waiting on a parts order. For less common boards, we source direct from the brand distributor and have it the next business day. You won’t hear us push a brand you don’t need; we repair what’s on your gate.

AfterCommon Electric Gate Repair Problems We See in Atherton Homes
- Post footing shift on clay soil. Atherton’s clay soil expands and contracts with the wet-dry cycle, and heavy ornamental gates lever against their hinge posts until the footing shifts. The gate sags, the loop detector reads it wrong, and the operator strains against the load. We repair the footing, re-set the post, and re-level the gate rather than just cranking the limit switch to compensate.
- Long cable runs degrading. Estates on minimum one-acre lots often run keypad and intercom wire 100 feet or more from the road to the gate operator. After a few years, these buried or conduit runs develop resistance, and the keypad goes intermittent or the camera drops signal. We tone the line, find the bad splice or corrosion point, and re-pull the run when needed.
- Battery backup failure after storms. Winter rain and the occasional storm knock out power across Atherton, and gates with dead battery backups lock owners out or leave the gate half-open. We load-test backup batteries on every repair, and replace them when they can’t hold a full cycle under load. If your gate dies the moment PG&E blinks, the backup is the first thing we check.
- Bespoke gate noise and vibration. Atherton’s custom metal gates are heavier than production residential gates, and when a bearing starts to go, you hear it before you see it. We trace the noise to the source: a dry bushing, a sprocket skipping, a rack pinion out of mesh. Then we replace the worn part, not the whole operator.

FAQs About Electric Gate Repair in Atherton
The panel usually isn’t the problem; the hinge post footing is. Atherton’s clay soil shifts with seasonal moisture changes, and a heavy custom gate levers against the post until the footing moves. A panel straightening treats the symptom. We excavate around the post, set a deeper concrete footing, re-bed the post, and only then re-level the gate so it stays put. Call (669) 666-6859 and we’ll diagnose the actual cause.
Yes, and this is one of the most common requests we get from Atherton homeowners. We add a second relay channel to the keypad or opener board, run a short jumper to the pedestrian gate’s operator, and program the dwell time so both gates open smoothly without colliding or fighting each other. You use one code for both gates. We do this same-visit on most estates. Call (669) 666-6859 for a written quote.
If the backup battery is healthy, the gate should complete at least one full open-close cycle on battery power or release to manual mode so you aren’t locked out. The problem we see in Atherton is that most commercial-grade backups were never load-tested after install, so they fail exactly when you need them. We test every battery on every visit and replace ones that can’t hold a cycle under full gate load. If your gate is dead after an outage, call (669) 666-6859.
Quiet operation comes down to three things: bearing condition, pinion-to-rack mesh, and gate level. If the gate sags, it drags, and if the rack and pinion are out of alignment, the operator grinds. We replace worn bearings, set the pinion mesh to the manufacturer’s spec, and level the gate so it travels true. A properly set Atherton estate gate should whisper, not groan. Call (669) 666-6859 and we’ll make yours silent.
Yes, entrapment protection is required on any automated gate, and yes, we test it on every repair. The UL 325 standard mandates photocells, edge sensors, or both, and if your gate’s safety system is misaligned or bypassed, it’s a serious liability. We cycle the gate with a test load at multiple heights, confirm the reverse function engages, and document the test on your invoice. Call (669) 666-6859 and we’ll run the full safety check.
Just off Selby Lane, our tech arrived at a gated estate where a 20-foot wrought iron swing gate had sagged so badly the safety photocells were misaligned and the LiftMaster operator was erroring out. The hinge post footing had shifted, not the panel, so we repaired the footing, reset the gate level, and recalibrated the rack and pinion so the gate now glides silent. While there, we synced the matched pedestrian gate to the same entry keypad, so the owners use one code for both.
That’s the kind of repair we do in Atherton: find the real problem, fix it completely, and leave the gate running the way the estate deserves. If your electric gate in Atherton is acting up, call (669) 666-6859. A live person answers, a written price comes before any work, and the repair is guaranteed in writing for 365 days.
