Why Calder Gate Repair Is Larkspur’s Preferred Gate Repair Company
Larkspur homeowners call us because we treat gate repair the way it actually works here. Driveways cut into hillsides, older electrical panels that were never sized for modern operators, and heavy wood or iron gates that slowly shift their posts. Our techs have seen all of it. When we arrive, we diagnose the failure in plain language, put a written price in front of you before turning a single bolt, and we don’t leave until the gate reverses cleanly on an obstruction test. Nico Alvarez, who leads Calder Gate Repair inside the Relay Home Co. family, built the operation around one thing: no vague promises. A written guarantee on every repair, a free second visit if the repair fails within 365 days, and a live arrival time you can track from your phone. Part of the Relay Home Co. family since 2009, independently owned and operated under The Relay Visibility Guarantee.
Our Gate Repair team serves all of Larkspur, from the streets off Magnolia Avenue up into the hillside neighborhoods near Baltimore Canyon. Dispatch and scheduling are coordinated from our San Francisco Bay Area office. The crews are local. The parts bins are stocked for the brands Larkspur homes actually use.
Sliding Gate Repair in Larkspur
Sliding Gate Repair in Larkspur almost always comes down to three things: the track, the rollers, and the operator that pulls the weight. Hillside properties in Larkspur often choose sliding gates because a swing gate would demand too much horizontal room on a sloped driveway. The trade-off is that silt and fine gravel wash across the track after every wet season, grinding down rollers and forcing the operator to work harder than it was sized for.
Track, Roller, And Operator Alignment
A sliding gate that shudders at mid-travel or stops with a fault code usually has a track issue hiding underneath. We level the track, replace worn or seized rollers, and check the operator’s current draw under load. On Larkspur’s graded driveways, a misaligned track will burn out a gate motor within a year if left alone. Most sliding gate repairs in Larkspur run $260 – $490 before parts, with heavier work like full track replacement going up from there.
When The Gate Moves But Won’t Fully Close
That’s often the limit switch, the small sensor inside the operator that tells the gate when to stop. A limit switch that has drifted means the gate closes short, or pushes past and trips the safety. We set travel limits, test obstruction reversal, and confirm the photocells see each other. It’s the kind of job that takes under an hour on site but prevents a gate from holding a driveway open all night.
Wrought Iron Gate Repair in Larkspur
Wrought Iron Gate Repair in Larkspur usually starts with a sag. A beautiful iron gate on a hillside driveway is heavy, and the post that carries it takes years of lateral load, irrigation moisture, and rain-season soil movement. Larkspur’s older homes, especially those built in the 1950s and 1960s along streets like Madrone Avenue and up toward the hills, often have original iron gates on footings that were poured shallow. The panel looks level. The post underneath has shifted.
Hinge Post Footing And Sag Correction
We re-pour hinge post footings more often in Larkspur than almost anywhere else we work. Just straightening the gate panel without re-footing the post fails within a season because the ground moves. A proper repair means excavating the footing, setting the post deeper, rebedding it in concrete, then re-hanging the gate and resetting the latch. Most wrought iron footing and sag repairs in Larkspur run $380 – $700, depending on post size and access to the footing.
Weld And Rust Repair
Coastal fog and winter rain find their way into every micro-crack in an iron gate. We grind out rust, weld cracked pickets or hinge points, and re-coat with primer and paint matched to the existing finish. Leaving rust alone means paying for a full gate replacement later. Weld and rust repair on a Larkspur iron gate typically runs $180 – $420 per section, done on site.

You don’t need a different gate tech for every brand. Calder Gate Repair’s techs are factory-familiar with nine major gate opener brands, including LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. Around Larkspur, we see a lot of Viking operators on older iron gates, DoorKing on the larger sliding driveway gates up in the hills, and Mighty Mule on the newer solar-powered installations.

Common Gate Repair Problems We See in Larkspur Homes
- Hinge post footing movement on sloped driveways. Larkspur’s hillside lots put sideways load on hinge posts that flat-lot gates never see. The gate panel looks level, but the post has shifted in wet soil, and sag correction alone won’t last. Re-footing is the only durable fix.
- Older subpanel circuits that can’t carry a modern operator. Many Larkspur homes run gate power from a subpanel that predates the current code. The operator trips the breaker under inrush load, and the homeowner hears an operator fault when the real problem is the circuit feeding it.
- Safety photocells knocked out of alignment by landscaping. Larkspur properties with seasonal planting around the gate line often bump or shade the photocells. The gate runs fine but has no working entrapment protection. We re-aim and test the beam as part of every tune-up.
- Wet-season track silt on sliding gates. Rain washes fine debris across Larkspur’s graded driveways and into slider tracks. Rollers grind, the operator overworks, and eventually the board burns out. Annual track cleaning prevents most of it.

We were called to a Madrone Avenue property where a double swing gate had been dragging for months. The homeowner had already had the panel straightened once. Our tech found the failure at the hinge post footing, re-poured the footing, corrected the sag, then swapped the tired LiftMaster operator and re-aimed the safety photocells so the gate reversed cleanly on obstruction. That gate has run without a manual assist since.

FAQs About Gate Repair in Larkspur
The problem is almost always the hinge post footing. Larkspur’s sloped, irrigated hillside driveways let posts move in wet soil even when the gate panel itself shows no obvious damage. We excavate, re-set the post deeper in concrete, and re-hang the gate so the latch lines up. Straightening the panel without re-footing fails within a season. Call (903) 417-0793 for an exact quote; estimates are free.
No, and we won’t pretend otherwise. New gate installations involve groundworks, power runs, safety edge and photocell placement, and operator sizing that has to be measured, ordered, and scheduled. We provide a free on-site measure and a written installation quote, then schedule the work. What we do offer same-day is repair: seized rollers, tripping breakers, failed control boards, and misaligned safety beams are all jobs we fix in one visit.
Calder Gate Repair services nine major brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. In Larkspur specifically, we stock control boards, limit switches, and photocells for Viking, DoorKing, and Mighty Mule because those are the operators we see most on local gates. If you know your brand, name it when you call and we’ll confirm parts on the spot.
Put the gate in motion and pass your hand across the photocell beam near the gate line. The gate should stop and reverse immediately. If it doesn’t, the safety system is defeated or misaligned and your gate is running without working entrapment protection. Entrapment protection is a genuine safety requirement, not a convenience setting. If your gate failed that test, call us and we’ll re-aim or replace the photocells and run a full obstruction test before we leave. Call (903) 417-0793 to schedule a safety check.
Yes, in many cases. Larkspur’s hillside lots often have long, rocky runs between the house and the gate, and trenching power can cost more than the operator itself. Solar operators with a properly sized panel and a good battery bank work well here because Larkspur gets reliable sun through most of the year. The catch is tree shade from the oak and bay canopy along the hills, which means the panel placement matters just as much as the operator spec. We’ll assess your actual sun exposure at the motor location and tell you honestly whether solar will carry the load year-round. Call (903) 417-0793 for a free site assessment.
Larkspur’s Hillsides Change The Math On Gate Operators
Here’s what no generic gate repair page tells you. Larkspur’s hillside lots often put driveways on grades steep enough that a swing gate needs a different operator leverage class than the flat-lot gates common in Corte Madera. The same LiftMaster unit that works a block away can stall mid-travel on a Larkspur slope. Gate operators here are also frequently fed from older subpanel circuits that were never sized for the inrush draw of a modern operator plus safety photocells. That means the breaker trips under load, the owner assumes the operator is bad, and a tech who doesn’t know Larkspur swaps a healthy motor and leaves the real problem behind. We size operators to the actual grade, check the circuit capacity at the gate column, and if the wiring is undersized, we say so in the written quote before any work starts. That kind of honesty is why Larkspur homeowners keep our number.
