AfterGate Company in Kentfield, CA
Most gate problems in Kentfield come down to two things: water and shifting ground. The Ross Valley rainfall funnel dumps 45 to 50-plus inches on this community every year, which corrodes iron hardware, swells wooden gate frames, and pushes concrete gate posts off-square as the clay soil expands. Homes here run large, custom, and expensive to replace, so repair done right matters. We answer the phone 24/7 and put every price in writing before work begins. Call (940) 412-7340 when a gate stops behaving, and we’ll walk you through what’s happening over the phone before we ever send a truck.
Why Kentfield Homes Are Different
Kentfield properties sit in a narrow valley where Pacific moisture channels in and then lingers. Dense redwood and oak canopy shades most lots, so after a winter rain the ground and the gate hardware stay damp for weeks. We routinely open operator housings here and find rust blooming around the circuit boards, water sitting in the bottom of the case, or corroded terminal strips that work fine in drier Marin towns. Homeowners in Kentfield learn quickly that a gate that works in October can fail by February without a single thing being bumped or hit.
The housing stock compounds this. Kentfield isn’t a neighborhood of off-the-shelf gates. These are long private driveways with ornamental iron, custom cedar, and low-voltage automation systems that were built when the house was built, often matched to the home’s architecture. When a cast-iron hinge post on a custom gate starts binding, ordering a replacement part isn’t a matter of grabbing something off a shelf. It’s measured, sourced, and fitted to the existing frame, which changes how we diagnose and quote every job here. The clay hillside soil also heaves and settles with each wet season, tilting posts just enough to throw a swing gate’s arc off by year’s end. That seasonal post shift is the single most common pattern we see across Kentfield driveways.
Our Main Kentfield Services
Here are the three Kentfield services homeowners call us about most, each with its own page that covers the work in full detail.
Gate Repair in Kentfield
Most repair calls in Kentfield start as a gate that drags on the ground, a latch that no longer catches, or a set of hinges that have sagged under a wooden gate swollen with winter moisture. We inspect the full swing or slide path, identify what moved or rusted out, and quote the fix before touching a single bolt. In this climate we pay special attention to the bottom of steel posts, where water collects and rust does its worst. Gate Repair in Kentfield explains the most common failures and what they cost to put right.
Gate Installation in Kentfield
New gate installations in Kentfield mean working with sloped driveways, custom property setbacks, and heavy materials that need proper concrete footing under a clay-soil load. Frame and materials come first, but placement and drainage dictate whether an install lasts a decade or starts racking within two winters. We measure, specify the right operators for the gate’s weight and travel arc, and install so the gate clears during wet-season ground shift. Gate Installation in Kentfield covers full planning, material choices, and what a Kentfield job typically includes.
Electric Gate Repair in Kentfield
In a damp, tree-covered valley like Kentfield, electric gate systems fail most often from moisture intrusion into the operator, boundary sensors knocked out of alignment by post movement, or dead capacitor and limit switch issues inside the control box. We diagnose the actuator – the motorized arm that physically pushes or pulls the gate – along with the safety loops and power feed, then show you exactly what failed. Electric Gate Repair in Kentfield walks through how these systems fail here and how we put them right.

FAQs About Gate Company in Kentfield

Most repairs and like-for-like equipment swaps don’t require permits.

What Kentfield Customers Say
"Good repair on a sagging gate and a new hinge welded on. Took them a couple days to get the part in, but they told me that up front and it's been solid since."
- Hector Villanueva"The opener gave out and we were manually pushing the gate for a week. Portcullis got us in quick, swapped the opener, and set up the remotes for both our cars. Great to have it working again."
- Priscilla Nava"Our driveway gate stopped halfway and wouldn't close, which is a problem when it's the only thing between the street and the yard. They came out same day, replaced the motor, and it's smooth again."
- Leonard Pace
