Why Kentfield Residents Choose Us for FAAC Service
We’ve been working on FAAC operators in Marin County long enough to know that a technician trained in Phoenix or Dallas is going to misdiagnose half the problems here. Kentfield’s 45–55 inches of annual rainfall — among the highest in Marin — creates failure modes that simply don’t exist in drier climates. Kevin Lewis, who grew up near Midtown Palo Alto and built his electrical foundation at Foothill College in Los Altos Hills, has spent 16 years tracking how moisture penetrates FAAC control boards, corrodes limit switches, and turns hinge pins into seized artifacts.
We’re not an authorized FAAC dealer. We don’t need to be. Our lead technician trained at FAAC factory courses back in 1987, and our team averages 15+ years fielding the 390, 400, 700, and 844 T series across Marin’s moisture-prone microclimates. We stock OEM FAAC parts for current 390 and 400 series operators, and we source quality-matched aftermarket components for legacy 700 and 844 T units when original parts sit on backorder. Most Kentfield competitors carry parts for two, maybe three gate brands; we stock and service nine — LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule.
Our 542 verified reviews averaging 4.9 stars reflect what happens when the person who owns the company is also the person who shows up with the tools. No rotating subcontractors, no call-center dispatchers guessing at your problem over the phone.
Common FAAC Gate Repair Problems We Solve in Kentfield
- Corroded limit switch contacts on FAAC 390 swing operators — Kentfield’s sustained dampness, especially in properties shaded by heritage oaks off Goodhill Road and surrounding hillside lanes, causes the micro-switches that tell the operator when to stop to oxidize and fail closed. The gate keeps trying to push past its mechanical stops, burning out the motor. We clean the contact assemblies and apply dielectric grease rated for marine environments.
- Hydraulic seal degradation on 400 series operators — Hillside properties throughout Kentfield often install gate equipment inside non-ventilated stone pillars or masonry enclosures for aesthetics. Summer heat buildup in these thermal masses accelerates hydraulic fluid breakdown, causing slow operation or mid-cycle stalls. We replace seals with upgraded compounds and modify ventilation where the pillar design allows.
- Control board conformal coating failure on 700 slide operators — The salt-laden fog that rolls off the Pacific and settles in Ross Valley eats at the protective coating on older 700 series electronics. Once moisture bridges traces, you get erratic behavior: phantom openings, refusal to respond to remotes, or the operator running continuously until thermal protection kicks in. We diagnose board-level faults in the field and either re-coat viable assemblies or replace with tested refurbished units.
- Motor gear stripping on 844 T pedestrian operators — Retrofitted to gates with swollen wood infill panels, these compact operators face load profiles they weren’t originally engineered for. Kentfield’s wet winters cause redwood and cedar panels to absorb moisture and expand, increasing swing mass by 15–20 percent. The 844 T’s nylon gearing wasn’t designed for that cyclical overload. We upgrade to brass or steel gearsets where the operator frame allows, or recommend appropriate replacement sizing.
- Hinge seizure and post heave from accelerated footer rot — This one’s almost uniquely Kentfield. The town’s position at the base of the Mount Tamalpais watershed means water tables stay elevated year-round. Wood posts rot at the concrete interface; steel posts rust through from the inside out. We perform hinge repair with stainless hardware, post realignment using engineered footings, and rust treatment on salvageable ironwork.
FAAC Service in Kentfield: What Local Conditions Mean for Your Equipment
Kentfield’s annual 50+ inches of rain seeps into gate post footings faster than in any other Marin town, causing the concrete to spall and the post to shift within 5–7 years — a failure timeline unique to this watershed zone. For FAAC owners, this isn’t abstract geology. A post that tilts even two degrees throws off the geometry that FAAC’s 390 and 400 series operators depend on for consistent limit switch engagement. The operator starts “hunting” — micro-correcting back and forth at the end of each cycle — which accelerates wear on the clutch assembly and eventually triggers fault codes that lock the system.
We’ve learned to check post plumb before we ever open the operator housing on a Kentfield call. On a steep driveway off Goodhill Road, we found a FAAC 390 swing operator stalling mid-cycle. The gate’s lower hinge had seized from corrosion where rainwater pooled against the iron post. We replaced the hinge with a stainless-steel version, cleaned and adjusted the limit switches, and remounted the operator on a 4-inch plinth to keep it dry. The gate has cycled smoothly through three rainy seasons since. That kind of fix requires in-house welding capability — something general fence contractors in Kentfield typically subcontract out or skip entirely.
FAAC Models & Products We Service in Kentfield
We stock and service the full FAAC residential and light-commercial line most commonly found in Kentfield’s estate properties:
- FAAC 390 — Swing operator for gates up to 800 lbs; the workhorse on Kentfield’s custom iron driveway gates. We carry OEM arm assemblies, limit switch modules, and control boards.
- FAAC 400 — Hydraulic swing operator for heavier gates; common on hillside properties with long, weighted infill gates. We stock seal kits, hydraulic fluid, and replacement pumps.
- FAAC 700 — Slide operator for commercial and large residential applications. Legacy units still running in Kentfield; we source matched aftermarket boards and gear motors when OEM parts are unavailable.
- FAAC 844 T — Compact pedestrian and light-duty swing operator. Frequently retrofitted beyond original spec in Kentfield’s mixed wood-and-iron gate installations; we upgrade gearing and recalibrate torque settings.
Our repair-over-replacement stance means we’ll rebuild a 400 series hydraulic unit when the casting is sound rather than sell you a new operator. For older 700 and 844 T models where FAAC has discontinued components, we use quality aftermarket parts that match original electrical and mechanical specifications — never universal-fit substitutes that require field modification.

FAQs — FAAC Gate Repair in Kentfield
The combination of sustained humidity and slight post settling from Kentfield’s saturated soils causes gate geometry to drift faster than in drier, more stable ground. We recommend annual limit switch verification for Kentfield properties versus the 18–24 month interval that suffices in Novato or eastern San Rafael. Call (831) 218-8355 to schedule; we’ll check switch contact condition and post plumb in the same visit.
Yes, if properly specified and maintained. The 390 is rated to 800 lbs and 16 feet, which covers most Kentfield estate gates. The critical factor is dynamic load: a gate on a slope fights gravity differently on open versus close cycles, and the operator must be torque-calibrated for that asymmetry. We’ve installed and maintained dozens of 390 units on Kentfield hillside properties; the failures we see almost always trace to improper initial specification or neglected hinge maintenance, not operator inadequacy.
Three measures specific to this microclimate: elevate the operator housing on a plinth or shelf to avoid ground splash, ensure the control box has intact gaskets and weep holes that aren’t clogged with debris, and schedule annual inspection of the conformal coating on 700 series boards or the limit switch assemblies on 390/400 units. We include all three checks in our Kentfield maintenance visits.
We do — quarterly or bi-annual service agreements that prioritize the components moisture attacks first: hinge pins and bushings, limit switch contacts, board coatings, and hydraulic fluid condition. For Kentfield’s 50+ inch rainfall zone, we generally recommend quarterly visits for commercial properties and bi-annual for residential estates with covered operator housings. Call (831) 218-8355 for plan pricing tailored to your FAAC model and gate configuration.
It will, but the operator must be sized for wet-weight, not dry-weight, and the control board needs seasonal torque recalibration. A redwood gate that gains 15 percent mass in winter will trigger overload faults on an operator spec’d for summer conditions. We see this constantly in Kentfield’s wood-and-iron hybrid gates. The fix isn’t replacement — it’s proper specification upfront and biannual recalibration. If your current operator is struggling seasonally, call (831) 218-8355 and we’ll measure actual wet-cycle load before recommending any changes.
