Fast, Reliable Gate Repair Across Kentfield
Gate repair in Kentfield typically runs $180–$650 depending on the failure, and most calls we receive from the 94914 area are completed same-day or next-day. Frank Delgado and our team have been driving out to Kentfield from San Diego for over 20 years, and we know the difference between a gate that needs a quick hinge adjustment and one that’s rotted through from the inside because of what this valley does to metal and wood.
If your gate is dragging, squealing, or won’t open at all, call us at (855) 671-2951. We’ll walk you through what we’re seeing, give you an honest repair-or-replace opinion, and get you scheduled.
Why Sierra Gate Repair San Diego Is Kentfield’s Preferred Gate Repair Company
We’ve earned 375 verified reviews averaging 4.9 stars across two decades of gate work, and a growing share of those come from Kentfield homeowners who found us after a generalist couldn’t solve the problem. They tell us the same thing: they want someone who understands why their gate failed, not just someone who can swap a motor.
Frank Delgado still runs the jobs personally. When you call Sierra Gate Repair, you’re getting the founder’s hands on your gate, not a rotating crew of subcontractors who might not recognize a 1980s LiftMaster operator from a modern smart-access system. That matters in Kentfield, where many properties along streets like Laurel Grove Avenue and Warner Canyon Road still run original hardware from the 1960s through the 1990s.
Our response time to Kentfield is typically same-day or next-day for standard repairs, and we carry parts for nine major brands including LiftMaster, FAAC, and Elite. That inventory, combined with our in-house welding capability, means we can often fix structural problems on the spot that other companies would need to outsource or replace entirely.
Our Gate Repair Services in Kentfield
Hinge Repair
Kentfield’s cast-iron and steel hinges take a beating. The wet winters swell the wood, the dry summers shrink it, and after enough cycles the hinge plates crack or the pins seize. We’ve replaced hinges on estate-style gates throughout the wooded hills above Sir Francis Drake Boulevard where the original hardware had simply crystallized from fatigue. When the base metal is still sound, we can weld and reinforce; when it’s rusted below 1/8 inch, replacement is the only safe call. A typical hinge repair or replacement in Kentfield runs $180–$340.
Post Repair
Redwood and cedar posts rot from the base up in Kentfield. The redwood duff holds moisture against the wood year-round, and older concrete footings often lack the drainage to let that moisture escape. We’ve re-set dozens of posts on sloped Kentfield driveways where the original footing had turned to crumbles. Our approach: extract the old post, install a galvanized post anchor with drainage gravel, and rehang the gate plumb. Post repair or replacement in Kentfield typically costs $280–$550 depending on depth, soil conditions, and whether we need to cut into existing hardscape.
Weld Repair
Our mobile welding rig lets us repair broken frames, cracked hinge mounts, and separated pickets on-site. This is critical in Kentfield, where many gates are custom-fabricated ornamental iron that can’t be replaced with off-the-shelf parts. We serviced a 1960s swing gate on Warner Canyon Road where the original FAAC hydraulic arm had seized from rust; the redwood duff had packed the hinge pockets solid, and the post footing had rotted through. We replaced the arm with a new FAAC 740, re-set the post in a galvanized anchor, and retrofitted the old concrete footing with drainage gravel. Weld repairs in Kentfield start around $220 for simple cracks and run to $480 for extensive frame rebuilding.
Gate Realignment
Long, sloped driveways are the norm in Kentfield, and gravity works against gates here. Hinges sag. Posts lean. Gates that once cleared the ground by two inches start dragging and chewing up the driveway surface. Realignment requires understanding the original grade, the current settlement, and whether the problem is the gate, the post, or the footing. Sometimes it’s all three. Realignment work in Kentfield typically runs $200–$420.

Trusted Brands We Service in Kentfield
We work on virtually every major gate brand, including LiftMaster, FAAC, and Elite, and we stock parts for all nine lines we service. That matters when your 1990s Mighty Mule board fails on a Sunday or your commercial DoorKing system needs a new limit switch before your tenant’s Monday opening. For Kentfield customers, this means faster turnaround and fewer callbacks. We don’t refer you to another company for parts we don’t carry. We don’t guess at compatibility. If we can’t fix it, we’ll tell you straight, but after 20 years we’ve encountered most failure modes at least once.
Common Gate Repair Problems We See in Kentfield Homes
- Moisture-swollen circuit boards in vintage openers. Original LiftMaster or FAAC openers from the 1970s through the 1990s fail when decades of valley humidity finally breaches the housing. Replacement parts are often discontinued, which means an honest upgrade conversation rather than a futile parts hunt.
- Bottom rail rot hidden under redwood duff. One-piece or early sectional wood gates on sloped driveways like those on Laurel Grove Avenue rack out of square because the bottom rail has rotted through undetected. The gate looks fine until it doesn’t close, and by then the damage has spread to the stiles.
- Cast-iron hinge fatigue from expansion cycles. The wet-dry cycle in Kentfield’s 94914 microclimate stresses cast iron more than in drier Marin towns. Hinges that would last 30 years in San Rafael often crack in 15 here.
- Debris-packed slide tracks. Redwood duff, the thick mat of fallen needles and bark, accumulates year-round in bottom tracks and around hinge bases. It holds moisture against metal and wood constantly, and it physically jams slide mechanisms. Local techs learn to budget extra time just for clearing organic debris before diagnostic work can begin.

FAQs — Gate Repair in Kentfield
Most “stainless” hardware sold at retail is 304-grade, which corrodes in Kentfield’s chloride-rich, high-humidity environment faster than 316 marine-grade or solid brass. The redwood duff holds moisture against the metal 24/7, so even quality hardware needs periodic inspection and lubrication. We specify 316-grade or hot-dip galvanized hinges for Kentfield installations, and we recommend annual maintenance checks. Call (855) 671-2951 to schedule — estimates are free.
BFT Ares boards and motors from the 1970s through 1990s are largely discontinued, and used parts are unreliable. We can retrofit a modern BFT or compatible operator to your existing gate structure, preserving the mechanical components that are still sound while upgrading the control system. Retrofit typically runs $650–$1,200 in Kentfield versus $1,800–$3,200 for full replacement. Call for a specific assessment.
Every 6–8 weeks during fall and winter, and monthly if your property sits under dense canopy. The duff packs tight, holds moisture, and accelerates track corrosion while physically jamming the roller mechanism. It’s the single most preventable cause of slide gate failure in Kentfield. We offer seasonal maintenance plans if you’d rather not handle it yourself. Call (855) 671-2951 to discuss.
Repair is viable if the rot is limited to the bottom 6–8 inches and the post is otherwise straight and crack-free. We can sister a repair post or use epoxy consolidants for localized decay. Replacement is necessary when rot extends above grade, the post has twisted, or the footing has failed. In Kentfield’s wet microclimate, replacement with pressure-treated or galvanized-anchor construction usually outlasts repair by 10–15 years. We’ll give you both options and our honest recommendation after inspection. Call for a free estimate.
Yes. Sloped driveways require limit switches set to accommodate the gate’s arc relative to grade, not just open and closed positions. A gate that closes fine on level ground can slam or drag on a slope. We also check for post lean under operating load, which is common on Kentfield’s hillside properties where soil shifts seasonally. Proper adjustment prevents motor strain and extends operator life by years. Call (855) 671-2951 to schedule.
