Fast, Reliable Gate Installation Across Kensington
Gate installation in Kensington, CA typically runs $2,800-$8,500 depending on materials, automation, and slope compensation, with most projects completed in one to three days. Ironworks Gate Co. has been serving Kensington homeowners since 1984, and we know the terrain here - steep hillside lots, narrow winding streets, and unincorporated county code - because we’ve worked it for over four decades.
We’re based in Los Angeles, but our crews route regularly to the East Bay Hills, and Kensington is a community we know well. From the craftsman bungalows along Arlington Avenue to the terraced cottages off Somerset Place, we’ve hung gates on driveways pitched 10 to 25 degrees, between retaining walls, and in the fog belt where marine moisture eats hardware alive. When you call (833) 754-7503, a live person answers - 24 hours a day, 7 days a week - and we’ll give you an upfront price before a single bolt is turned. No surprises on the bill. That’s a square deal.
Why Ironworks Gate Co. Is Kensington’s Preferred Gate Installation Company

Our technicians are background-checked, uniformed, and trained on nine gate-automation brands - Viking, Ghost Controls, and DoorKing among them - so the correct fix is made on the first visit, whatever is on your driveway. The 90-Day Done Right Promise, our Keystone Standard, applies to every gate job: written, no paperwork, no arguing. If it’s not right, we come back and make it right.
We answer the phone live, day or night. No voicemail trees. No callback queues. No waiting until Monday morning. And our $89 Seasonal Tune-Up catches the hinge drift and post heave that Kensington’s clay soil and fog-cycle cause before they become a full re-hang.
Our Gate Installation Services in Kensington
Swing Gate Installation
Swing gates remain the most common request in Kensington, and for good reason - they suit the period architecture of 1920s-1950s craftsman homes. But Kensington’s steep driveways demand more than standard hardware. A gate hung level on a 20-degree slope will drag its trailing edge through the concrete within a season. We custom-calculate hinge placement and often specify slope-rated articulating-arm openers from FAAC or Elite rather than linear actuators that bind under angled load. On Somerset Place, we recently replaced a 1950s wrought-iron swing gate with a custom redwood carriage-house door. The 20-degree driveway slope required articulating-arm openers from FAAC, and because the gate was wedged between a retaining wall and hillside planting, we used a post-sleeve anchor with a concrete collar to combat the expansive clay soil that heaves in winter rains.
Wood Gate Installation
Kensington’s original redwood gates are 50 to 80 years old now, and many are failing at the post base or hinge mortise. We build replacement wood gates to match - clear-heart redwood or cedar, hand-forged style hinges where appropriate, and always with drainage detailing that accounts for the fog-belt moisture that accelerates rot here faster than in Richmond or El Cerrito below. The daily thermal cycle - wet fog burning off to afternoon sun - causes wooden gates to swell and warp seasonally, throwing hinges out of plumb. We engineer for that movement with adjustable hinge sets and proper clearance gaps. A wood gate in Kensington that ignores this cycle will need realignment by the second spring.
Automatic Gate Installation
Automating a gate in Kensington carries a regulatory layer that flat neighboring cities rarely trigger. Because Kensington is unincorporated Contra Costa County within a designated fire hazard severity zone, automatic driveway gates must meet county fire-access code: fail-safe open on power loss, Knox key switches for emergency responder access. We install these as standard, not as an afterthought. Our Gate Installation team is certified on nine automation brands - including Viking and Ghost Controls - and we stock parts locally so Kensington customers aren’t waiting on shipping when an opener fails. Most automation retrofits are completed in a single visit.
Sliding Gate Installation
Where swing radius is limited by terraced lots, retaining walls, or hillside plantings, a sliding gate can be the only practical solution. We’ve installed track-mounted and cantilever sliding systems on Kensington properties where the gate run parallels the driveway cut. These require precise grade for the track or counterbalance engineering for cantilever designs - work that benefits from local knowledge of how the clay soil heaves and settles through the winter.

Trusted Brands We Service in Kensington
Our technicians carry factory-authorized training and field stock for nine major automation brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For Kensington’s hillside installations, we frequently specify FAAC and Elite articulating-arm systems rated for slope, and Viking and DoorKing for heavy-duty estate gates.

The correct component is installed on the first visit, and the job is protected by our 90-Day Done Right Promise - written, no hassle, no exceptions.
Common Gate Installation Problems We See in Kensington Homes
- Standard linear actuators binding on steep driveways. Kensington’s 10-25 degree driveway pitches will cause conventional linear actuators to drag, stall, or fail prematurely. Slope-rated articulating-arm hardware is essential, not optional.
- Posts heaving out of plumb by spring. The expansive clay soil on hillside cuts shifts with winter rains. Without post-sleeve anchoring and concrete collars, a gate that latched cleanly in October won’t close by March.
- Fire-code violations on automated gates. Installing automatic driveway gates without fail-safe open on power loss or Knox key switches violates Contra Costa County fire-access code in Kensington’s hazard zone, triggering costly retrofits after inspection.
- Wood gates swelling and warping in the fog cycle. Dense marine layer most mornings followed by afternoon sun creates a daily thermal stress that flat, drier East Bay cities don’t impose. Hinges need seasonal adjustment, and wood species must be chosen for stability.
Pricing for Gate Installation in Kensington, CA
A typical manual swing gate installation in Kensington runs $2,800-$4,500, including posts, hardware, and hang. Automated swing gates with slope-rated openers range $4,200-$7,800 depending on materials and access-control features. Custom wood carriage-house doors with full automation typically fall between $6,500-$8,500. Sliding gate systems start around $5,500 and can exceed $9,000 for cantilever designs on difficult grades.
What moves the number: driveway slope (steeper means more complex hardware), existing post condition (clay-heaved posts need full replacement), fire-code compliance features (fail-safe systems, Knox switches), and material choice (clear-heart redwood versus steel). We settle the full price before work begins - no surprises on the bill. Call (833) 754-7503 for a free estimate at your Kensington property. Senior and Veteran discounts of 5% apply, always.

FAQs - Gate Installation in Kensington
Because Kensington is unincorporated Contra Costa County within a designated fire hazard severity zone, county fire-access code mandates that automatic driveway gates fail open when power is lost and include Knox key switches for emergency responder override. This is a regulatory requirement, not a recommendation - gates without these features will fail inspection and require costly retrofit. We install fail-safe systems as standard on every automated gate in Kensington. Call (833) 754-7503 to confirm your existing gate meets code.
Kensington’s hillside cuts contain highly expansive clay that heaves with winter rains, routinely shifting gate posts several degrees out of plumb by February. We address this with post-sleeve anchoring and concrete collars as a near-mandatory practice on wooden gate installations here - what looks like a latch adjustment in October often becomes a full re-plumb by spring without proper anchoring. Our $89 Seasonal Tune-Up catches early movement before it becomes a major repair.
Slope-rated articulating-arm openers from FAAC or Elite outperform standard linear actuators on Kensington’s 10-25 degree driveway pitches. Linear actuators bind, drag, or fail prematurely under angled load. Articulating arms maintain proper geometry through the full swing arc, and we specify them for nearly every hillside installation in Kensington. We stock these systems and can typically install same-day once the gate is built.
Yes, with engineering assessment. Many Kensington wrought-iron gates from the 1920s-1950s use non-standard post spacings, hand-forged hinges without modern mounting patterns, and obsolete hardware that can’t interface with off-the-shelf opener brackets. We fabricate custom mounting solutions in our shop and specify openers matched to the gate’s weight and wind load. The fire-code compliance layer - fail-safe open, Knox switch - applies to any automation retrofit in Kensington’s hazard zone. Call (833) 754-7503 for a free evaluation of your existing gate.
Kensington sits at fog-belt elevation in the East Bay Hills, receiving dense marine layer most mornings that burns off to afternoon sun. This daily wet-dry thermal cycle causes repeated swelling and contraction in wood fibers, throwing hinges out of plumb and stressing joints in ways that flat, drier cities like Richmond or El Cerrito don’t typically experience. We specify stable wood species, proper sealing schedules, and adjustable hinge hardware to manage this movement. Annual realignment is common and worth budgeting for.
