We’ve been driving out to Kensington for years, and it’s different territory from flat-lot San Diego work. The hillside grades, the 1920s-era pillars, the county permit path — these aren’t afterthoughts for us. Frank Delgado and our team have installed gates on Amherst Avenue, Arlington Avenue, and throughout the 94530 zip, and we’ve learned that a gate that works in Kensington needs to be built for Kensington’s specific conditions: persistent fog moisture, steep approaches, and legacy hardware that wasn’t designed for modern automatic openers.
Why Sierra Gate Repair San Diego Is Kensington’s Preferred Gate Installation Company
Our Gate Installation team knows the local workflow. Kensington isn’t a city — it’s an unincorporated community governed by Contra Costa County. That means gate permits and inspections run through the county building department in Martinez, not any municipal office. Most East Bay gate contractors aren’t set up for this. We are. We’ve filed enough county permit packages to know exactly what Contra Costa wants to see for residential gate plans, and we handle that paperwork so you don’t get stuck in a loop between departments that don’t exist.
Our 375 verified reviews averaging 4.9 stars include repeat Kensington customers who’ve called us back for second properties or referred neighbors. That track record matters in a small community where word travels fast. Frank Delgado still runs the jobs personally — you get the founder’s eye on grade measurements, hinge placement, and whether your existing brick pillars from the 1930s can handle a modern steel gate or need reinforcement first.
Response time to Kensington is typically same-day or next-day for estimates, depending on current project load. We’re familiar with the winding hillside streets, the narrow driveways off Arlington, and the parking constraints that can slow down crews who don’t know the area. That local knowledge translates to faster, cleaner installations.
Our Gate Installation Services in Kensington
Swing Gate Installation
Swing gates are the most common request we get in Kensington, and they’re also the most likely to fail if installed without accounting for local conditions. The steep grades on most Kensington lots mean standard hinges won’t cut it — we regularly spec drop-rod hardware, adjustable ball-bearing hinges, and sloped-frame fabrication that keeps the gate plumb while following the grade. We recently replaced a warped wooden garden gate on a 1920s Tudor Revival home on Amherst Avenue, where the original wrought-iron hinges were lag-screwed into soft redwood posts that had rotted from persistent fog moisture. We retrofitted a new powder-coated steel swing gate with drop-rod hardware to handle the 10% grade, preserving the historic look while ensuring smooth operation.
For automatic swing gates, we install operators from FAAC, Linear, and Viking — brands with proven reliability in coastal moisture environments. We factor in wind exposure on exposed hillside lots, which affects operator torque requirements and battery backup sizing.

Pedestrian Gate Installation
Kensington’s pedestrian gates are often the most character-defining element of a property — original wrought-iron or hand-built wooden garden gates integrated into hedgerows and stone or brick pillar entries. These aren’t standard catalog items. We fabricate custom steel frames to match existing pillar spacing, or rebuild wooden gates with pressure-treated or cedar stock that resists the fog-belt moisture better than the old redwood that was common in the 1920s–1940s builds.
Many Kensington pedestrian gates are hinged to or latched against mature arbor-vitae hedges, laurel, or Eugenia shrubs that have grown into the gate path over decades. A technician who doesn’t factor in root intrusion lifting a concrete hinge-post footing, or hedge growth binding the latch side, will miss the root cause of repeated misalignment calls. We measure the full gate path, assess root systems, and set posts with proper clearance or specify trim-back agreements where needed.

Security Gate Installation
Kensington’s unincorporated status and hillside isolation mean security concerns are real — long driveways, limited street lighting on some lanes, and properties that back onto open space. We install steel security gates with access control integration: keypad, intercom, or smartphone-operated systems from LiftMaster and DoorKing. For commercial-grade reliability on high-use gates, we spec FAAC and BFT operators — Italian-built systems we know inside and out from 20 years of focused gate work.
Security gate installation in Kensington often requires navigating the county permit process for structures over 6 feet or any gate with electrical components. We handle the plans, the structural calculations for wind load on hillside exposure, and the inspection scheduling.

Sliding Gate Installation
Sliding gates can work in Kensington, but they’re not automatic fits. The steep grades that define most local driveways require careful track placement — sometimes a recessed ground track with drainage slots to prevent leaf and debris buildup, sometimes a cantilever design that avoids ground contact entirely. We evaluate each site individually: driveway pitch, available slide clearance, and whether the gate needs to clear a crowned or sloped surface. For properties where a swing gate would require an impractical swing radius, a properly engineered sliding gate is often the better long-term solution.

Trusted Brands We Service in Kensington
We work on virtually every major gate operator brand, and we stock parts and full systems for FAAC, Linear, and Viking — three brands we install frequently in Kensington’s moisture-heavy environment. FAAC’s hydraulic operators handle heavy gates and continuous cycling without overheating; Linear’s edge sensors and control boards have proven reliable in our coastal California installs; Viking’s rack-and-pinion drives offer smooth, quiet operation that suits residential neighborhoods where noise carries. Because we carry in-house inventory and have two decades of supplier relationships, we can source non-stock items faster than generalist competitors who need to subcontract or special-order. For Kensington customers, that means shorter wait times and fewer return trips.
Common Gate Installation Problems We See in Kensington Homes
- Wood gate frames warp and rot at the bottom rail due to persistent marine moisture from Kensington’s fog belt. The nightly moisture rolling in from the Golden Gate corridor keeps wood perpetually damp, and we see bottom rails and hinge stiles fail on a predictable cycle. Full replacement with pressure-treated or composite materials is usually the only lasting fix.
- Original wrought-iron hinges fail because they were attached to redwood posts with no anchor plates. The posts rot at the base from the same fog-driven moisture, causing gate sag that gets worse every season. We replace with steel posts set in concrete or retrofit anchor plates into existing brick pillars where structurally sound.
- Mature hedges grow into the gate path, causing chronic misalignment. Arborvitae, laurel, and Eugenia root systems can lift concrete footings over years, and hedge mass binds the latch side. Hinge adjustment alone won’t fix this — we assess root intrusion and specify either post relocation or controlled hedge management.
- County permit delays stall projects when contractors unfamiliar with Contra Costa County’s unincorporated workflow submit incomplete plans. We file complete packages the first time, with structural details for hillside wind exposure and electrical plans for automatic operators.

FAQs — Gate Installation in Kensington
Yes, most driveway gate installations in Kensington require a permit through Contra Costa County’s building department, not a city office. Because Kensington is unincorporated, there’s no municipal building department — applications go to Martinez, and inspections are scheduled through county staff. We handle the permit package, including site plans, structural details for hillside wind exposure, and electrical plans for automatic operators. Call (855) 671-2951 and we’ll confirm whether your specific project triggers permit requirements.
Often yes, but they need assessment first. Many Kensington pillars from the 1920s–1940s were built without embedded anchor plates or steel reinforcement, and mortar degradation from decades of fog cycles can weaken the structure. We inspect for cracks, hollow-sounding mortar, and adequate depth for hinge bolts. If the pillars are sound, we retrofit with embedded plates and proper hardware. If not, we quote reinforcement or new pillar construction. Call (855) 671-2951 for a structural evaluation — estimates are free.
Kensington’s position in the Bay Area fog belt means nightly marine moisture accelerates rust on ferrous hardware and keeps wooden frames damp year-round. Even powder-coated steel hinges show surface oxidation within a few seasons without proper maintenance. We spec marine-grade stainless or hot-dip galvanized hardware for Kensington installs, and we design drainage into wooden gate bottom rails to reduce rot. For automatic systems, we use sealed operators and weatherproof enclosures. The fog isn’t a dealbreaker — it’s just a factor you build for.
Sometimes, but often the root cause is broader. Redwood posts rot at the base from persistent soil moisture and fog, and simply dropping in a new post repeats the cycle. We evaluate drainage, post depth, and whether the gate load exceeds what a wood post can handle long-term. For Kensington’s conditions, we often recommend steel posts set in concrete with proper drainage rock, or retrofitting to existing brick pillars if structurally feasible. The fix needs to last longer than the original did. Call (855) 671-2951 and we’ll diagnose the full failure mode.
A sliding gate can work, but steep grades require specific engineering. Standard ground-track systems need precise leveling and drainage to prevent debris accumulation and track corrosion. For severe grades, we may recommend a cantilever design that eliminates ground contact, or a recessed track with integrated drainage. We measure driveway pitch, available slide clearance, and gate weight before recommending any system. Not every steep Kensington lot suits sliding — sometimes a properly engineered swing gate with grade hardware is the better solution. We’ll tell you straight which approach fits your specific site.
