Fast, Reliable Gate Installation Across Kensington
Gate installation in Kensington typically runs $2,800–$7,500 depending on gate type, materials, and whether you’re replacing century-old posts on a hillside lot or installing fresh on a new driveway. We’re usually on-site in Kensington within 24–48 hours, and most installations finish in one to two days.
We’ve been crossing the Bay into Kensington for years — up Arlington Avenue, through the Arlington Park neighborhood, past the Kensington Circus Pub — and we know the terrain. These hillside properties, the 1920s craftsman bungalows on terraced lots off Colusa Avenue, the Tudor revivals along Santa Clara Avenue with their original wrought-iron gates now rusted through from decades of fog belt moisture. Kevin handles it personally. Our Gate Installation team doesn’t subcontract out to anonymous crews. We show up, assess the actual conditions — the clay soil, the grade, the corrosion pattern — and we install gates built to survive here, not in some inland suburb.

Why Ironclad Gate Repair Service San Francisco Is Kensington’s Preferred Gate Installation Company
We’re gate-only specialists. Eleven years, nothing but gates. Over 1,000 neighbors trust us — 1,072 verified reviews averaging 4.8 stars — and that track record matters when you’re trusting someone with a 400-pound steel gate on a steep grade.
Kensington homeowners call us back because Kevin handles it personally. He’s the lead technician on every job, not a dispatcher sending random subcontractors. When we installed that swing gate on Santa Clara Avenue — the one with the 1920s Tudor revival posts shifted two inches out of plumb — Kevin was the one who spotted the clay soil expansion, realigned the posts, and spec’d stainless steel hinges to outlast the fog. That accountability is why Kensington customers refer us to neighbors on the same hillside block.
We stock parts and weld on-site. No waiting two weeks for a hinge fabrication shop in Sacramento. No “we’ll come back when the part arrives.” We carry LiftMaster, DoorKing, Elite, and Mighty Mule components in our trucks, and our mobile welding rig handles structural repairs on the spot.
Response time to Kensington: typically next-day, sometimes same-day if the schedule allows. We know the Arlington Park, Kensington Heights, and Colusa Hill neighborhoods well enough to estimate drive time without GPS.
Our Gate Installation Services in Kensington
Driveway Gate Installation
Kensington’s steep hillside driveways — some hitting 15% grades or more on the terraced lots off Arlington and Colusa — demand more than a standard opener. We install incline-rated operators: LiftMaster and Ghost Controls systems engineered for continuous duty on steep grades. A standard opener burns out in 18 months here. We see it constantly. We spec the right motor from day one, with battery backup for the power outages that roll through the East Bay hills during winter storms.
Swing Gate Installation
The classic choice for Kensington’s period homes — craftsman bungalows and colonial revivals with existing stone or wrought-iron posts. But those original posts? Often 60–100 years old, rusted at the base, shifted by clay soil expansion. We don’t just hang a new gate on failing infrastructure. We assess post integrity, realign or replace as needed, and install adjustable hinge systems that tolerate seasonal soil movement. The swing gate we put in on Santa Clara Avenue — that was real work, not a hardware swap.
Sliding Gate Installation
When hillside grade makes swing gates impractical, sliding gates run parallel to the fence line on a track system. Critical in Kensington: the track foundation must account for clay soil heave. We pour reinforced concrete footings below the frost line, isolated from the gate posts to prevent transfer of soil movement. We’ve replaced three sliding gate tracks in Kensington Heights in the past two years where generalist installers skipped this step and the track buckled within one winter.
Pedestrian Gate Installation
Side-yard access, garden entries, pool enclosures — smaller scale, same Kensington conditions. We use marine-grade stainless hardware and pressure-treated cedar or powder-coated aluminum panels rated for fog belt exposure. The pedestrian gates on hillside properties often need self-closing hinges with adjustable tension to compensate for gate sag as posts shift. We install them with room to adjust.
Double Gate Installation
Wide driveway openings on Kensington’s larger hillside parcels — the colonial-style homes with circular drives off Kensington Road. Double gates need synchronized operators, center drop pins rated for soil movement, and careful engineering so the meeting stile seals properly even as posts shift seasonally. We center-pin with adjustable receivers, not fixed plates that bind after one rainy season.
Security Gate Installation
Access control integration — keypad, intercom, remote entry — for Kensington properties where privacy and security matter. We wire for future expansion: video intercom, cell-phone app control, license plate recognition. The fog belt corrosion hits electrical contacts hard; we use sealed conduits and marine-rated junction boxes.

Common Gate Installation Problems We See in Kensington Homes
- Salt-air corrosion destroys hinges and opener chains in 3–5 years. Kensington’s fog belt exposure — measurably more moisture than Richmond or El Cerrito below — accelerates rust through standard galvanized hardware. We spec stainless steel or hot-dip galvanized components with corrosion-resistant coatings, and we inspect annually for early failure signs.
- Expansive clay soils shift gate posts seasonally. The hillside clay swells in winter rains, shrinks in dry summers, heaving posts enough to throw latches and auto-closers out of alignment annually. We install adjustable hardware and engineer post footings to tolerate movement without binding.
- Steep driveway grades burn out standard automatic openers. Kensington’s terraced hillside lots strain motors designed for flat terrain. We spec incline-rated operators — LiftMaster and Ghost Controls systems built for continuous duty on grades — and we size motors with 25% excess capacity for longevity.
- Original 1920s–1950s posts and anchors fail from age and corrosion. Many Kensington properties still rest on 60–100-year-old post anchors, rusted through at the concrete interface. We extract and replace with modern galvanized or stainless embeds, engineered for current loads and soil conditions.

FAQs — Gate Installation in Kensington
Yes — because Kensington is unincorporated Contra Costa County, not an incorporated city, gate installation permits route through the Contra Costa County Building Department in Martinez, not a local city hall. This routinely surprises homeowners and can stall projects when contractors assume standard municipal timelines. We handle the permit application as part of our installation service, including site plans and structural calculations for hillside footings. Call (866) 788-1265 and we’ll confirm exactly what your property requires.
Standard galvanized springs in Kensington’s fog belt typically fail in 3–5 years, versus 7–10 years inland. We upgrade to stainless steel or epoxy-coated spring systems that last 8–12 years despite the marine moisture. Annual inspection catches corrosion before catastrophic failure — we include this with every installation. Call (866) 788-1265 to schedule a corrosion assessment.
No — standard auto-openers rated for flat or mild grade will burn out within 18–24 months on Kensington’s typical hillside driveways. You need an incline-rated operator: LiftMaster and Ghost Controls both manufacture systems engineered for continuous duty on grades up to 15% or steeper. We size motor capacity with 25% headroom for longevity. Call (866) 788-1265 and Kevin will measure your grade and spec the right unit.
Kensington’s elevation in the East Bay hills fog belt delivers measurably more moisture than flatland neighbors — wood panels absorb persistent marine condensation, and without adequate drainage gaps and protective finish, rot penetrates in 4–6 years versus 10+ inland. We specify pressure-treated cedar or redwood with marine-grade sealant, design panels with bottom drainage clearance, and use composite or aluminum frames where the client wants minimal maintenance. Call (866) 788-1265 for material options.
The expansive clay soils throughout Kensington’s hillside neighborhoods swell in winter rains and shrink in summer dryness, heaving gate posts enough to throw latches, auto-closers, and meeting stiles out of alignment seasonally. We install adjustable hinge systems, center-drop pins with slotted receivers, and engineer post footings isolated from surface soil movement. Annual adjustment is normal here — we build it in. Call (866) 788-1265 for a post-alignment check.
