Why Calder Gate Repair Is Fairfax’s Preferred Electric Gate Repair Company
Fairfax homeowners deal with a specific set of gate problems that flatter parts of Marin simply don’t see. Steep driveways, redwood roots, winter runoff, and older gate installs that were never permitted or built to current code mean repair work here often goes deeper than swapping a circuit board. Our technicians know the difference between a failed operator and a post footing that shifted after two wet winters, because we see both on a weekly basis across Fairfax, from the hills above Deer Park to the streets off Sir Francis Drake Boulevard.
Nico Alvarez leads our gate repair team, and he is the person who sets the standard for every Fairfax job: diagnose first, quote in writing, then fix. Fairfax customers consistently tell us the same thing: the technician showed up when promised, explained the failure in plain English, and the invoice matched the agreed price. Every repair carries our 365-Day Done Right Promise. If the same failure returns within 365 days, Calder returns at no charge. That promise is stated in writing on every job, and a free second visit is included with every repair, no fine print.
We are part of the Relay Home Co. family, established 2009, and each location operates independently under The Relay Visibility Guarantee. For Fairfax residents, that means a live arrival time you can track, before-and-after photos of the work, and a digital invoice you pay from a link. Scheduling is coordinated from our San Francisco Bay Area office, and crews serve Fairfax locally.
Automatic Gate Repair in Fairfax
Automatic Gate Repair in Fairfax usually means one of three things: a swing gate that won’t open or close, a slide gate that stalls partway, or an opener that runs but won’t move the gate. The repair itself depends entirely on what failed. Sometimes it is a worn limit switch, the small sensor that tells the gate when to stop. Other times it is a hinge post that has leaned out of plumb on a sloped Fairfax lot, binding the gate and overloading the motor. We diagnose before we quote, and the written price you approve is the price you pay. Most automatic gate repairs in Fairfax run $225 – $425 before parts.
Operator Diagnostics and Repair
We test the full circuit: control board, transformer, limit switches, receiver, and the motor itself. On LiftMaster and Linear units, phantom stops often trace back to a failing obstruction sensor rather than the board. We identify the exact failed component and replace only what is needed.
Track and Hinge Alignment
On Fairfax hillside properties, the gate and the operator often work against each other because the post has moved. We re-shim hinge posts, clear slide gate tracks of oak and bay debris, and re-set drive chains or rack and pinion so the motor is not fighting the gate.
Electric Gate Motor in Fairfax
Electric Gate Motor failure in Fairfax is frequently misdiagnosed as a dead battery or bad remote, when the real problem is that the motor has been run past its duty cycle on a gate it was never sized for. This is especially common on solar-powered operators installed on remote, wooded driveways where a homeowner bought a light-duty opener for a heavy steel gate. Most electric gate motor repairs in Fairfax run $300 – $650 depending on the motor type and whether we are rebuilding or replacing it. We confirm the motor is actually bad before recommending replacement, and we show you the failed part.
Swapping a Burned-Out Motor
We replace motors on swing and slide operators from LiftMaster, FAAC, Viking, and Linear. The work includes re-checking the torque settings, re-balancing the gate, and testing the full open/close cycle under load, not just on a test bench.
Converting From Solar to Wired Power
Some Fairfax lots are far enough up the hill that wiring is expensive and solar seems like the only option. But if a solar operator has failed twice in three years, the honest answer is usually a larger battery bank and a properly rated motor, not another cheap panel kit. We will give you a written comparison of both options before you spend anything.
Trusted Brands We Service in Fairfax
Our Fairfax technicians are factory-familiar with nine major gate opener brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. If you have a swing gate opener that stopped responding, our Electric Gate Repair team can usually identify the failed part on the first visit. We keep common control boards, remotes, limit switches, and safety sensors stocked for Linear, Viking, and Ghost Controls units because those are the brands we see most often on Fairfax properties. If the part is not on the truck, we order it and schedule the return visit before leaving your driveway. No open-ended waiting.
Common Electric Gate Repair Problems We See in Fairfax Homes
- Undersized concrete post footings on sloped lots. Tall swing gates lean into the operator as the footing shifts, stressing the hinge post and stalling the drive. We regularly re-pour footings deeper than the original install because the hillside soil moves more than homeowners expect.
- Oak and bay leaf debris plus winter runoff clogging the slide gate track. The debris jams the loop detector or trips the operator’s obstruction sensor, causing phantom faults that make the gate stop and reverse for no obvious reason. Fairfax’s wet winters make this a seasonal recurring issue.
- Cheap solar openers run past their duty rating. A 12V solar operator on a remote Fairfax driveway sounds appealing until the battery and control board fail within a season or two. We see this on hillside properties where the gate is heavy and the opener was under-specced from day one.
- Safety sensor alignment after storms. Photo-eyes knocked out of alignment by wind or vegetation make the gate refuse to close. This is often a 30-minute fix, but it can also point to a mounting bracket that was never stable on the post.

FAQs About Electric Gate Repair in Fairfax
Because the problem is almost never the hinge bolts. On Fairfax’s sloped lots, the concrete post footing shifts over time, and the post itself leans. Tightening the hinges just pulls the gate against a leaning post, which stresses the operator and eventually stalls it. The proper fix is re-setting or re-pouring the footing, re-plumbing the post, and then re-hanging the gate. That runs $400 – $900 depending on footing size and access. Call (903) 417-0793 and we will inspect the post before recommending anything.
Yes. Electric gates in Fairfax are required to meet UL 325 entrapment protection standards, which means photo-eyes, a reversing edge, or both, depending on the gate type and installation. Older unpermitted installs around Fairfax often lack these entirely. When we repair any gate in Fairfax, we test reversal pressure and sensor function as part of the job, and we will tell you in writing if your gate is not compliant. The repair to bring it into compliance typically runs $150 – $350 per sensor set.
Almost certainly not. Rainy mornings in Fairfax usually mean water or debris in the track, a wet obstruction sensor, or a ground fault at a low-mounted control box. We see this all winter. The first diagnosis step is checking power and track condition before touching the operator. We will not recommend a new operator unless we can show you the failed component and explain why replacement beats repair. Call (903) 417-0793 and a live person will book the diagnosis.
Most repairs in Fairfax are completed in one visit, and that visit usually lasts one to three hours depending on the fault. For true emergencies, like a gate stuck open on a property with young children or pets, we prioritize same-day dispatch to Fairfax whenever crews are available. Because we schedule with live, trackable arrival times rather than arrival windows, you know when we are coming. Every repair gets a free second visit within 365 days if the same failure returns.
Yes. We keep common LiftMaster, Linear, Viking, and Ghost Controls parts on our service vehicles, and we can source FAAC and BFT components quickly through Bay Area suppliers. For Fairfax customers, that usually means the difference between a one-visit repair and a two-visit repair. If the specific board or motor is not in stock, we give you a hard date for the return visit before we leave your driveway. The written price covers the full job, parts included.
Fairfax Gate Repair That Accounts For the Hills
Fairfax’s combination of steep, wooded lots and older unpermitted gate installs means many electric gate failures trace back to undersized post footings or 12V solar operators pushed past their duty cycle, rather than the operator itself. In flatter parts of Marin, a gate that stops mid-travel is usually an electrical fault. Here, it is just as often a structural one. That changes the repair order: we check the post, the track, and the power supply before we condemn a motor.
Our tech was called out to a ridge-top property near the end of Bolinas Road where a 16-foot slide gate had stalled mid-travel after two winters of redwood-root heave. The post footing had tilted, throwing the rack and pinion out of mesh. The LiftMaster operator was fine. We re-poured a deeper footing, re-shimmed the rail and re-engaged the drive, then re-aimed the safety photocell and tested reversal per UL 325 before we called it done. That is what Fairfax repair actually looks like: finding the root cause on a hillside, not just swapping parts until something works.
