Fast, Reliable Gate Installation Across Kentfield
Gate installation in Kentfield typically runs $3,800–$12,500 depending on size, material, and automation, with most residential driveway projects completed in 2–4 days. We’re Sierra Gate Repair, and our Gate Installation team regularly works in the 94914 zip code and the wooded hills around the Meadow Club, College Avenue, and Kent Woodlands. Frank Delgado still leads every install personally, and we’ve been driving up to Kentfield from our San Diego base for years — we know the long, sloped driveways, the heavy redwood canopy, and the way this valley’s wet microclimate destroys gate hardware faster than almost anywhere else in Marin County.

Why Sierra Gate Repair San Diego Is Kentfield’s Preferred Gate Installation Company
We’ve earned 375 verified reviews averaging 4.9 stars, and a growing share of them come from Kentfield homeowners who found us after a general fence company couldn’t handle the grade, the automation, or the wet-weather engineering. Frank Delgado doesn’t send trainees. He shows up, measures the slope, checks the drainage pattern, and specs hardware that won’t corrode out in year three.
Our response time to Kentfield is typically same-day or next-day for consultations. We carry parts and welding equipment in the truck, so when we find rotted posts or a bent frame on an existing gate, we fix it on the spot rather than ordering out.
We also know the local permitting landscape. Marin County’s unincorporated areas around Kentfield have specific setback and height rules for driveway gates, especially on properties bordering open space. We’ve navigated enough of these to keep projects moving without surprises at inspection.
Our Gate Installation Services in Kentfield
Swing Gate Installation
Swing gates dominate Kentfield’s estate properties, and they present a specific challenge here. The long, sloped driveways rising from Sir Francis Drake Boulevard into the Kent Woodlands and Greenbrae border areas mean gates must swing on true vertical hinges, even when the driveway falls away at 8–12% grade. We’ve replaced too many gates installed by generalists where the uphill post was cut short and the gate dragged within a season. Frank specs heavy-duty adjustable hinge sets with extended j-bolts, and we pour footings deep enough to stay put through the wet-dry cycles that heave lesser concrete work. A typical manual swing gate installation in Kentfield runs $3,800–$6,200; automated swing systems with LiftMaster or Viking operators add $1,800–$3,400.
Sliding Gate Installation
When the driveway slope is too steep for a swing gate, or when the entry sits close to College Avenue or Wolfe Grade with limited swing radius, we install sliding gates. This is where Kentfield’s redwood duff becomes the enemy. We recently replaced a heavy redwood swing gate on a long, sloped driveway near the Meadow Club in Kentfield, where the original wood posts had rotted from moisture trapped by fallen bay laurel leaves. We installed a LiftMaster pneumatic slide opener with a custom stainless-steel track, and bedded the new cedar posts in gravel-collared concrete to withstand the wet duff. For sliding gates, we spec V-track or cantilever systems with debris shields and elevated track brackets where the leaf litter piles deepest. Sliding gate installations in Kentfield typically cost $5,500–$9,500 with automation.
Security Gate Installation
Kentfield’s large-lot homes, many set back hundreds of feet from the road, benefit from security gates that do more than mark the property line. We install systems with keypad, telephone entry, and smart-home integration — BFT and FAAC operators with cell-module add-ons that let you open the gate from your phone anywhere. For properties near the open space boundaries or the more secluded lanes off Woodland Road, we also spec loop detectors and safety edges that prevent closure on wildlife or delivery vehicles. Security gate systems with full access control in Kentfield range from $7,500–$12,500 depending on entry system complexity.
Pedestrian Gate Installation
Even properties with automated driveway gates need matching pedestrian entries. We fabricate these in-house to match the main gate’s style, whether that’s ornamental iron, redwood with black iron framing, or the modern horizontal cedar that’s become common on Kentfield’s newer custom builds. We pay attention to latch height, self-closing hinges for pool compliance, and hardware that won’t seize after two wet winters. Pedestrian gate installations typically run $1,800–$3,500.

Trusted Brands We Service in Kentfield
We work on virtually every major gate brand, including FAAC, BFT, Linear, and Viking — no referrals, no guesswork. For Kentfield installations, we stock operators and parts from these manufacturers locally, which means faster turnaround when a motor fails or an access panel needs replacement. Our familiarity with nine major brands (LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, Mighty Mule) matters especially on custom installs where the homeowner or architect has specified a particular European operator for quiet operation or a specific commercial-grade system for multi-tenant access. We program, we troubleshoot, and we warranty the integration.
Common Gate Installation Problems We See in Kentfield Homes
- Wood gate posts rot from the base up due to constant moisture in the duff layer. The fallen redwood needles and bay laurel leaves hold water against the post like a sponge, and by year five or six, even pressure-treated lumber shows decay at ground level. We spec cedar or redwood heartwood with gravel collars and proper concrete elevation, or we move to steel posts clad in wood for the visible faces.
- Slide gate tracks clog with organic debris — redwood needles, bay laurel leaves, and the fine particulate that filters down through the canopy year-round. The packed material holds moisture against the track and rollers, accelerating wear and causing the motor to strain. We design with debris gaps, elevated track brackets, and quarterly maintenance access in mind.
- Ornamental iron gates rust prematurely at hinge points and bottoms even when powder-coated, because prolonged contact with damp duff and Kentfield’s persistent high humidity breaches the coating at wear points. We spec stainless or galvanized hardware for these locations and design gates with bottom rails elevated above the debris layer.
- Gate alignment fails on sloped driveways when footings settle unevenly through the wet season. Kentfield’s clay-heavy soils expand and contract dramatically, and gates installed without deep, properly reinforced footings drift out of plumb within two years. We engineer for the soil, not just the gate.

FAQs — Gate Installation in Kentfield
Quarterly at minimum, and monthly during peak fall drop from October through December. The redwood duff in Kentfield packs tight and holds moisture continuously, so waiting six months usually means track corrosion and motor strain. We offer maintenance plans for properties with heavy canopy cover. Call (855) 671-2951 to schedule a cleaning and inspection.
Heart-grade cedar or redwood with the sapwood stripped, set in concrete with a gravel collar and elevated 2–4 inches above finish grade. Even then, expect 5–7 years before checking at the base in Kentfield’s wet duff conditions. For longer life, we recommend steel posts with wood cladding, which we fabricate in-house. We can show you both options on-site.
Yes. We regularly install LiftMaster and Linear operators with MyQ or similar cell-module integration, and we can tie into most home automation systems. The key is matching operator torque to gate weight — a heavy redwood or iron gate in Kentfield needs a properly spec’d motor, not a residential light-duty unit forced into service. Frank evaluates gate mass and duty cycle before recommending any automation package.
Powder coat fails at mechanical wear points — hinges, latches, anywhere metal rubs metal. In Kentfield, the constant humidity and duff contact accelerate the breach. Once moisture reaches bare steel under the coating edge, rust spreads underneath the film. We replace hinge hardware with stainless or hot-dip galvanized components, and we design gates with bottom rails kept clear of debris contact.
Yes, with engineering. Downhill slopes require bottom guides, catch posts, and operators with dynamic braking to prevent runaway. We’ve installed several on Kentfield’s steeper lanes, including the Meadow Club area, using FAAC and BFT commercial-grade operators with adjustable close-force limits. The site evaluation determines whether a slide gate is viable or whether a swing gate with grade-mounted hinges makes more sense. Call (855) 671-2951 and we’ll measure your slope.
