Gate repair in Portola Valley usually comes down to two things: a gate that won’t open, or a gate that won’t stay where it should. Most jobs we handle in Portola Valley run $180 – $340 for opener and alignment work, and heavier structural repairs like hinge replacement or post resetting typically land between $450 and $1,400. We know these hills, the long driveways off Alpine Road and Westridge, and the way a winter storm can knock a solid wood gate out of square overnight. If your gate is stuck, sagging, or making a sound it shouldn’t, call (669) 666-6859 and a live person will pick up, day or night.
Why Calder Gate Repair San Jose Is Portola Valley’s Preferred Gate Repair Company
Calder Gate Repair is the dedicated gate division inside the Relay Home Co. family, founded in 2009. We’re independently owned and operated, and every job we run in Portola Valley follows the same three rules: a written price before any work starts, a written guarantee on every repair, and a free second visit if the repair fails within the 365-Day Done Right Promise window. That’s not an upsell. It’s printed on every invoice.
Portola Valley homeowners call us because our technicians arrive in uniform, background-checked, and with a live, trackable arrival time on their phone. No four-hour windows. No voicemail tag. You see who’s coming, when they’ll pull up, and the exact number you’ll pay before a single bolt gets turned. The Relay Standard is how we run every job from the first call to the final invoice you pay from a link.
We also understand what these specific gates demand. A solid redwood swing gate on a steel post frame behaves differently than a light aluminum driveway gate in a flat subdivision. Nico Alvarez, who leads our gate repair work, trains our techs on nine major opener brands including FAAC, BFT, Linear, and Viking, because Portola Valley estates rarely have the same opener twice in a row.
Styles & brands we work with
Gate Welding in Portola Valley
Gate welding in Portola Valley is usually the fix when a hinge tears off, a steel frame cracks at a stress point, or a wrought iron picket snaps after years of wind load against the Santa Cruz Mountain foothills. We don’t patch and hope. We grind, bevel, weld, and reinforce so the repair outlasts the original joint. A cracked steel gate frame weld typically runs $250 – $550 depending on access and the number of passes needed; a torn hinge plate replacement with welding usually lands between $300 and $700.
When Welding Beats Replacement
A custom steel driveway gate can cost $4,000 – $12,000 to replace in Portola Valley. Welding a failed joint for a few hundred dollars keeps the original design intact and the automation system’s weight settings unchanged. We always check the surrounding metal for fatigue cracks before we burn a bead, because a second crack two inches away means you’ll be calling us again.
Post and Hinge Plate Repairs
When expansive clay soil shifts a post, the hinge plate becomes the weakest part of the assembly. We weld reinforced plates back to the post and realign the gate so the operator isn’t fighting the extra load. This is common after heavy winter rains along Portola Road and throughout the Westridge area.
Commercial Gate Repair in Portola Valley
Commercial gate repair in Portola Valley centers on access points for ranches, stables, private roads, and a handful of small commercial properties along Alpine Road. These gates see more cycles per day than a residential driveway gate, and they’re often paired with keypads, loop detectors, and heavier rack-and-pinion operators. A commercial opener repair in Portola Valley typically runs $280 – $650 before parts; a full operator replacement on a large sliding gate can range from $1,200 to $3,800 depending on the drive type and gate weight.
Safety Edges and Loop Detector Repairs
Marine layer moisture from the coastal side of the mountains corrodes exposed loop detector splices and safety edge wiring faster than people expect. We test the full safety circuit on every commercial gate we touch in Portola Valley, because a gate that reverses when it shouldn’t is a liability no business should carry. Repairs here typically run $180 – $420.
Scheduled Maintenance for High-Cycle Gates
Gates that cycle fifty times a day wear gears, chains, and rollers on a schedule. We offer maintenance agreements for commercial properties in Portola Valley that include written inspection reports and before-and-after photos, so you have a record of what was checked and what was replaced.
Trusted Brands We Service in Portola Valley
Our techs are factory-familiar with FAAC, BFT, Linear, Viking, LiftMaster, Ghost Controls, DoorKing, Elite, and Mighty Mule. In Portola Valley, we stock common FAAC and Linear parts on our trucks because those show up most often on older estate gates in the area, but we order BFT and Viking parts with next-day delivery when a repair needs something specific. That means less waiting and fewer return trips. If your opener is doing something odd, tell us the brand when you call (669) 666-6859 and we’ll tell you what we think it is before we even dispatch.

AfterCommon Gate Repair Problems We See in Portola Valley Homes
- Post shift after heavy rain. Expansive clay soil around Portola Valley swells when it gets wet, then contracts as it dries. That cycle pushes hinge posts out of level and makes swing gates bind or scrape against the latch side.
- Stripped gears from wind load. A solid infill gate acts like a sail in a winter storm. High wind pressure pushes against the rack and pinion drive, which can strip gears or overheat the motor before the gate even moves.
- Corroded terminals and splices. Marine layer moisture works into exposed wiring connections on gate operators and loop detectors. The result is intermittent faults: the gate opens halfway, stops, or refuses to close without several retries.
- Sagging wooden gate panels. Long, heavy redwood and cedar gates absorb moisture and swell, then sag at the latch corner. We reinforce the frame and re-square the panel so the operator doesn’t fight extra dead weight.

FAQs About Gate Repair in Portola Valley
Portola Valley’s expansive clay soils swell when saturated and contract as they dry, which slowly pushes hinge posts out of alignment over repeated wet-dry cycles. A binding gate is usually the first sign. We fix it by resetting the post to level, re-squaring the gate on its hinges, and adjusting the operator limits so the motor isn’t fighting misalignment. In severe cases we pour a wider footing to reduce future movement. Call (669) 666-6859 and we’ll tell you over the phone whether your gate needs a simple limit adjustment or a full post reset.
Every automated gate has a manual release mechanism, usually a keyed cylinder or a pull handle on the operator housing. For swing gates, the release disengages the drive arm so the gate swings freely by hand. For sliding gates, a release lever or chain lets you push the gate along its track. We always walk Portola Valley customers through this procedure after installing or repairing an opener, because winter storms knock out power to the hills regularly. Keep the release key somewhere you can find it in the dark.
Yes, in most Portola Valley cases we can. A sagging wooden gate usually has a failing corner joint or a frame that’s racked out of square. We re-square the frame, add steel reinforcement plates or a diagonal tension brace, and replace worn hinges with heavier units rated for the gate’s weight. Typical cost runs $450 – $900 depending on gate size and hardware. Replacement only makes sense when the wood itself is rotted or split beyond repair.
First check that the photocells are still aligned and not caked with mud or debris blown in by the wind. Portola Valley storms knock branches and leaf litter across driveways, and a blocked or misaligned sensor will stop the gate mid-cycle or keep it from closing. Also look for loose wiring at the sensor connections, especially if the gate worked fine before the storm. If the gate reverses for no reason or opens and stops repeatedly, call (669) 666-6859 and we’ll diagnose it over the phone.
We repair both. Commercial gate work in Portola Valley covers ranch entrances, private road gates, and small commercial properties, including heavy sliding gates, keypad access, loop detectors, and safety-edge systems. A typical commercial opener repair runs $280 – $650 before parts. We carry commercial-rated hardware and we schedule around your access hours, not ours.
