We’ve been driving to San Anselmo from Los Angeles for 14 years, and the gate problems here aren’t like anywhere else in Marin. The creek, the fog, the hillside grades — they all punish gates differently. Our Gate Installation team knows what fails and what lasts.
Why Ironwood Gate Repair Los Angeles Is San Anselmo’s Preferred Gate Installation Company
San Anselmo homeowners don’t need a general handyman who “does gates too.” They need someone who understands why a standard zinc-plated hinge seized solid after one wet winter on a Brookside Avenue property, or why a swing gate arm geometry calculation that works in San Rafael won’t clear the uphill grade on a 94960 hillside lot.
Our 233 verified reviews at 4.7 stars include repeat customers from the Sir Francis Drake corridor and the flats near San Anselmo Creek. David Kaplan serves as Field Supervisor on every installation, so the person with final accountability is the same person measuring your driveway slope and selecting your automation brand. We don’t rotate crews or subcontract the welding.
We’re fluent across nine automation brands — LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule — which means we install what works for your property, not what we happen to stock. Our in-house welding and parts capability lets us fabricate custom brackets or repair hardware on-site rather than ordering out and leaving your gate half-finished.
Our Gate Installation Services in San Anselmo
Swing Gate Installation
Swing gates dominate San Anselmo’s older neighborhoods, where Craftsman and Victorian driveways were designed for manual double-leaf entry. Hillside lots throughout 94960 change everything. The uphill leaf needs careful arm geometry to avoid ground-strike on the opening arc, and the downhill leaf fights gravity on the close. We engineer these installations with adjustable FAAC or Viking actuator systems that compensate for grade, and we pour footings deep enough to survive the soil movement that follows major rain years.
Double Gate Installation
Double swing gates are the traditional choice for San Anselmo’s pre-1950 homes, many with original redwood or wrought-iron frames that deserve period-matched hardware. We fabricate custom steel or aluminum frames when the original is beyond saving, and we source hardware that matches the aesthetic — whether that’s hand-forged strap hinges for a Redwood Road cottage or concealed modern closers for a renovated Colonial Revival on Center Boulevard.
Security Gate Installation
San Anselmo’s security gate customers split between creek-adjacent properties needing flood-resilient automation and hillside homes wanting controlled access without sacrificing views. We install BFT and Linear systems with keypad, intercom, or cellular entry, and we spec stainless or hot-dip galvanized hardware as standard for any property within the flood zone. A security gate that fails open after one storm season isn’t security — it’s decoration.
Sliding Gate Installation
Sliding gates make sense where swing clearance is limited, but San Anselmo’s grades complicate track installation. We level and anchor track beds with proper drainage to prevent the debris buildup and frost heave that misalign gates over time. For properties with significant slope, we sometimes recommend cantilever systems that don’t rely on ground track at all.
Pedestrian Gate Installation
Walk gates in San Anselmo often match an existing driveway gate’s style and hardware, but they’re also the most frequently used — and the first to show corrosion at the latch and hinge points. We spec marine-grade fasteners and adjustable self-closing hinges for pedestrian gates, especially on creek-adjacent properties where humidity stays elevated year-round.
Driveway Gate Installation
Full driveway gate installations in San Anselmo start with understanding your access pattern and your property’s specific failure risks. Flood-prone lots need elevated footings, sealed posts, and corrosion-resistant hardware. Hillside lots need grade-aware automation geometry. Flat, well-drained properties near the top of the valley have different priorities. David assesses each site personally before we quote.

Trusted Brands We Service in San Anselmo
We install and automate with FAAC, BFT, Linear, and Viking systems, and we stock parts for all nine brands we support. For San Anselmo customers, this means faster turnaround when a motor fails or an access panel needs reprogramming — we’re not waiting on a distributor to ship a proprietary bracket. After the 2015 flood, we replaced a pair of wrought-iron swing gates on a Sir Francis Drake Boulevard property whose concrete footings had heaved six inches, twisting the LiftMaster LA500 slide opener bracket; we poured new footings 30 inches deep, fitted hot-dip galvanized hinges from Viking, and automated the gate with a FAAC 740 to withstand future inundation. That kind of end-to-end capability — structural repair, hardware fabrication, and automation integration — is what gate-only experience delivers.
Common Gate Installation Problems We See in San Anselmo Homes
- Post rot at grade from creek flood saturation. Wooden gate posts in San Anselmo’s low-lying corridors fail within 7–10 years without deep footings and proper sealant. The 2005 and 2015 flood events saturated soil for weeks, and even properties not directly inundated saw accelerated decay from elevated water tables. We install pressure-treated posts with concrete footings minimum 30 inches deep, or we spec aluminum or steel posts for flood-zone properties.
- Corroded standard zinc hinges and latches seizing after one flood event. The mineral-deposit crust left by receding floodwater acts like a binding agent, and the galvanic corrosion beneath it destroys standard hardware in a single season. We stock stainless steel and hot-dip galvanized hinges specifically because we’ve seen zinc-plated components fail catastrophically on San Anselmo Creek properties.
- Flood-heaved concrete footings misaligning swing gates and stressing opener arms. When a footing shifts even two inches, the gate leaf torques on every open-close cycle. The actuator arm fights the misalignment until the motor burns out or the mounting bracket shears. We see this most on Sir Francis Drake Boulevard corridor properties, and the fix requires re-poured footings with proper drainage, not just a new motor.
- Persistent valley fog accelerating rust on ferrous hardware above the flood zone. San Anselmo’s fog-funneling geography keeps humidity high even on hillside lots far from the creek. Gate hardware that would last 15 years in drier inland towns shows pitting and operation drag within 8–12 years. We spec powder-coated or stainless hardware as standard, not as an upgrade.
Pricing for Gate Installation in San Anselmo, CA

FAQs — Gate Installation in San Anselmo
San Anselmo’s creek-adjacent properties and fog-funneling valley geography keep soil moisture persistently high, accelerating wood decay at post bases. Wooden posts here often show structural rot within 7–10 years without deep footings and sealant, compared to 15+ years in drier inland areas. We recommend pressure-treated posts set in concrete minimum 30 inches deep, or aluminum/steel posts for flood-prone lots. Call (833) 805-4890 for a site-specific recommendation.
Stainless steel or hot-dip galvanized hinges, latches, and fasteners — never standard zinc-plated hardware. The 2005 and 2015 floods proved that zinc-plated components seize and fail within one inundation cycle on San Anselmo Creek properties. We stock both stainless and hot-dip galvanized options and install them as standard for any property in the flood zone. Call (833) 805-4890 and we’ll assess your specific exposure.
Yes, the Town of San Anselmo requires a building permit for driveway gates over 6 feet in height and any automated gate system. Properties in the creek corridor may also need floodplain review if footings encroach on regulated areas. We handle permit documentation as part of our installation process and coordinate with Marin County when floodplain issues arise. Call (833) 805-4890 and we’ll verify requirements for your specific address.
Steep grades change the geometry of swing gate operation, creating ground-strike risk on the uphill side and gravity-drag on the downhill close. Standard actuator arms calibrated for flat driveways will bind, stall, or prematurely fail on San Anselmo’s hillside lots. We spec grade-aware systems from FAAC and Viking with adjustable torque and limit settings, and we engineer arm mounting geometry specifically for your driveway slope. Call (833) 805-4890 for a field measurement.
Aluminum or steel gates with stainless or hot-dip galvanized hardware, mounted on deep concrete footings with proper drainage, outlast wood in flood-prone areas. If you prefer wood for aesthetic reasons, we recommend aluminum-frame gates with wood infill panels that can be replaced independently if damaged. Automation systems should be mounted above historical flood levels with sealed conduit runs. Call (833) 805-4890 for a flood-resilient design consultation.
