Why San Anselmo Residents Choose Us for FAAC Service
We’ve been working on FAAC operators in Marin County for over 16 years. Kevin Lewis — our owner and lead technician — grew up near Palo Alto’s Midtown neighborhood and cut his teeth in the hands-on vocational program at Foothill College in Los Altos Hills. That foundation shows up in how we diagnose FAAC problems: we don’t swap parts hoping something sticks. We trace the fault to its source.
San Anselmo’s mix of pre-WWII Craftsman homes, terraced lots, and creek-basin moisture creates a specific wear pattern on FAAC equipment that general contractors miss. We’ve re-plumbed posts on Lansdale Avenue after flood heave, replaced hydraulic seals in 390 operators cooking inside unventilated stone pillars, and treated corrosion on 400-series boards in north-facing redwood shade where morning fog never lifts. Our 542 verified reviews averaging 4.9 stars reflect that specificity — customers notice when you actually understand their gate, not just their brand name.
We stock FAAC OEM motors, boards, and seals for the 390 and 400 series. For discontinued models, we use high-quality aftermarket equivalents we’ve field-tested. Our in-house welding means structural repairs — broken frames, damaged posts, twisted hinge plates — don’t get referred out. From the motor to the weld, it’s our work.
Common FAAC Gate Repair Problems We Solve in San Anselmo
- Hydraulic fluid breakdown in FAAC 390 operators. San Anselmo’s valley-floor heat reflection off stucco and asphalt turns unventilated stone pillar housings into ovens. The 390’s hydraulic fluid degrades faster here than in cooler coastal Marin, causing sluggish operation or mid-cycle seizure. We drain, flush, and refill with heat-stabilized fluid — or relocate the operator to a ventilated housing when the geometry allows.
- Post-heave misalignment of swing-arm brackets. The clay soils along Sir Francis Drake Boulevard and adjacent streets swell with winter saturation, then shrink in summer drought. A post that was plumb in October can shift two inches by March, binding the FAAC swing arm against its bracket. We re-set with rebar-reinforced footings below the frost line — deeper than original installations typically went.
- Control board corrosion on FAAC 400-series operators. North-facing lots under mature redwood and oak canopy never fully dry between storms. The 400’s board enclosure isn’t fully sealed against persistent damp, and we’ve traced intermittent faults to trace corrosion on relay contacts. We clean, treat, and reseal — or upgrade to a gasketed aftermarket enclosure when OEM parts are exhausted.
- Track jamming on FAAC 740 slide gates. Winter debris floods wash gravel, bark, and silt across driveways on the valley floor. The 740’s nylon guide rollers bind or crack when forced through packed sediment. We clear, inspect, and replace rollers with sealed-bearing upgrades that handle San Anselmo’s wet-dry cycle better than stock components.
- Undersized hinge hardware on uphill-swinging wooden gates. San Anselmo’s terraced lots often have original wooden swing gates installed with decorative hinges never meant to handle the torque of a FAAC 390 operator pulling a 200-pound panel uphill. We upgrade to adjustable ball-bearing hinges and reinforce the post connection — otherwise the motor fights the gate every cycle.
FAAC Service in San Anselmo: What Local Conditions Mean for Your Equipment
San Anselmo’s location at the confluence of San Anselmo Creek and Ross Creek creates a flood dynamic that directly shapes how we service FAAC equipment here. Stormwater backs up into gate motor pits along Ross Avenue and Grenadier Lane — not every winter, but often enough that we’ve made elevating FAAC 390 operators on concrete plinths a standard recommendation for these blocks. This modification rarely comes up in uphill Fairfax or the hillside neighborhoods of San Rafael, where drainage is natural and motor pits stay dry.
The clay subsoil compounds the problem. After significant flood seasons, gate posts along the Sir Francis Drake corridor routinely shift out of plumb as saturated clay swells, then shrink as it dries. We’ve learned to spot the early signs: a FAAC 390 that worked fine in September starts “hunting” at the close limit by February, the swing arm chattering against a bracket that’s no longer square. Re-plumbing and re-setting posts has become a predictable late-winter service pattern specific to these valley-floor blocks — something no generic FAAC troubleshooting guide addresses because it’s rooted in San Anselmo’s creek-basin geography, not the operator’s design.
FAAC Models & Products We Service in San Anselmo
We stock and service the full FAAC residential and light-commercial line most common in San Anselmo’s residential neighborhoods:
- FAAC 390: Hydraulic swing operator, workhorse of the pre-WWII home market here. We carry OEM motors, seal kits, and control boards; for discontinued hydraulic rams, we source aftermarket equivalents tested in Marin conditions.
- FAAC 400: Electro-mechanical swing operator, popular for lighter wooden gates on terraced lots. Boards and gearboxes in stock; corrosion-damaged enclosures get upgraded sealing.
- FAAC 740: Slide gate operator for longer driveways off Sir Francis Drake and side streets. We stock replacement rollers, chain, and limit switches — critical when debris flooding jams the track.
- FAAC 844 T: Commercial-duty slide operator for multi-gate properties and HOA entrances. Heavy-duty gear sets and brake assemblies available through our parts network with 2–3 day turnaround.
Our stance on parts: genuine FAAC OEM when available and cost-effective, proven aftermarket when factory parts are discontinued or back-ordered. We never install a component we wouldn’t warrant for our own property.

FAQs — FAAC Gate Repair in San Anselmo
Water infiltration into the hydraulic ram or control enclosure is the usual culprit in San Anselmo, especially on north-facing lots where fog and runoff linger. The 390’s limit switches can also fault if the post has heaved slightly, changing the gate’s travel geometry. We pressure-test the hydraulic circuit, inspect the seal condition, and check post plumb before declaring it an electrical issue. Call (831) 218-8355 — we’ll pinpoint it in one visit, estimates are free.
Sometimes. If the board was powered when water hit, component damage may be irreversible. If it was de-energized and dried promptly, we can often clean corrosion from relay contacts and reseal the enclosure with upgraded gasketing. We stock replacement 400-series boards for when repair isn’t viable. The key is not cycling power repeatedly — that converts a recoverable board into scrap. Call (831) 218-8355 before you try resetting the breaker again.
Don’t force the operator — you’ll strip the clutch or damage the gear set. Clear visible debris by hand, then call us. We disassemble the guide carriage, inspect rollers for cracks, clean the track channel, and check for bent rail sections. We also assess whether your drainage pattern needs correction to prevent repeat jamming. Most 740 track issues in San Anselmo resolve in a single visit.
Yes. We install 24V battery backup systems compatible with FAAC 390 and 400 operators, sized for 15–25 full cycles depending on gate weight and length. For San Anselmo properties in PSPS zones — particularly the wooded hillside areas — this prevents being trapped inside or outside during planned outages. Battery systems require annual load testing; we include this in our maintenance visits.
Original posts on San Anselmo’s pre-WWII homes were often set shallow in concrete footings without rebar, sized for manual operation. A 390 exerts 350–400 lbs of dynamic force at the bracket. We test post stability with a load gauge and inspect for rot at the concrete interface. If the post moves more than 1/4 inch under hand pressure, it won’t handle the operator. We quote re-setting with a proper footing before any motor installation — no surprises after the fact. Call (831) 218-8355 for a structural assessment.
