Larkspur is a small city with two very different gate environments. The canyon side stays wet under redwood shade; the bay side eats mild steel with salt air. We know which side you’re on because we work both every week, and that shapes the parts we carry and the fixes we recommend. More on that below.
Why Latch & Post Gate Repair Is Larkspur’s Preferred Gate Repair Company
Latch & Post Gate Repair is part of the Cedarwell family of independently owned and operated gate specialists, and we’ve focused on gates only since 2009. That narrow focus means our technicians have seen the exact failure patterns that repeat across Larkspur: the rust-seized hinge post on a Baltimore Canyon cottage gate, the corroded operator board on a Corte Madera Inlet-facing driveway, the binding swing arm on a 12% grade. When a Gate Repair call comes in from Larkspur, we already know which questions to ask before the truck moves.
We carry stainless hinge pins, galvanized post bases, and sealed operator boards on our trucks specifically because Larkspur’s two micro-climates demand them. A shiny zinc-plated hinge that holds up fine in San Rafael will start flaking within eighteen months on a bay-side Larkspur fence. We don’t install that hardware here. Every technician is background-checked, wears a uniform, and follows the Cedarwell C.A.R.E. values on every visit: Clean up like it is our own home, Ask before we move or touch anything, Respect the family’s time and quiet hours, Explain the price before the work.
Every job, whether it’s a simple latch swap or a full commercial gate rebuild, is covered by the 365-Day Done Right Promise. If the repair isn’t right, we make it right. No argument, no fine print.
Gate Welding in Larkspur
Gate welding in Larkspur is often the difference between a hinge post that lasts five years and one that fails in two. The salt-laden air near the Corte Madera Inlet and the steady damp under the redwood canopy both attack mild steel, and a welded repair done with the right rod, the right joint prep, and the right finish holds up where a bolted patch will not. Most welded hinge-post repairs on residential gates here run $220 to $480, and a full weld-and-reinforce job on a large driveway gate runs $450 to $900.
Hinge and post restoration
When a gate sags and drags on the strike side, the hinge post is usually the root cause. A thinned or cracked weld at the hinge barrel allows the leaf to drop, so the latch no longer lines up. We cut out the failed weld, clean the base metal back to bright steel, weld with a rod matched to the post material, and refinish with a zinc-rich primer before painting. On bay-side Larkspur properties we also replace the fasteners with stainless, because the original zinc hardware is nearly always the first thing to let go.
Frame and panel reinforcement
Older wooden gates in Old Town Larkspur often have steel frames behind the board face that rust from trapped moisture. The wood hides the damage until the gate is visibly out of square. We weld in replacement frame members, reinforce corners where the original welds cracked, and drill drain holes so water stops pooling inside the lower rail. That last step matters more in the canyon lots where the frame stays wet eight months a year.
Commercial Gate Repair in Larkspur
Commercial gate repair in Larkspur covers the automated sliding and swing-arm gates at the Larkspur Landing corridor, multi-family properties, and the private drives off Magnolia Avenue. These gates cycle hundreds of times a day, and the salt air on the bay side of town is hard on contactors, limit switches, and control boards. A commercial gate service call in Larkspur typically runs $350 to $1,100 depending on whether we’re replacing a safety edge, rebuilding a roller carriage, or swapping a DoorKing or BFT control board, and written pricing comes before any work begins.
Operator and control board service
Most commercial gate failures in Larkspur trace to a control board that’s been cooked by corrosion, a limit switch that’s no longer reading, or a safety loop that’s tripped. We service DoorKing, Elite, BFT, and Viking operators, and we stock boards and loop detectors locally so a commercial gate doesn’t sit open for a week. When the repair is done, we test the full open-close cycle and the safety reverse function before we leave.
Track, roller, and cantilever work
Sliding gates on bay-side commercial lots in Larkspur chew through steel rollers and track because the marine air pits the bearing surfaces. We replace worn rollers with sealed-bearing units, re-level track that has shifted in the fill soil near the inlet, and reweld cracked cantilever frames. The spec on the coast side is always stainless or galvanized hardware; painted steel parts come back to bite within a season or two.
Trusted Brands We Service in Larkspur
Our technicians are factory-trained on the brands Larkspur families and property managers actually use: DoorKing, Elite, Viking, and Ghost Controls, along with LiftMaster, FAAC, BFT, and Linear. We keep the common boards, remotes, photo eyes, and limit switches for these systems on our trucks and in local stock, which means a failing DoorKing operator on a Magnolia Avenue driveway gets diagnosed and repaired without waiting for a shipped part in most cases. When a Viking board corrodes out on a Corte Madera Inlet property, we can usually swap it same visit because we anticipated the failure mode. That’s the value of working every week in Larkspur rather than driving in cold from another county.
Common Gate Repair Problems We See in Larkspur Homes
- Rust-seized hinge pins and latches on bay-side lots. The marine air off the Corte Madera Inlet pits zinc-plated hardware fast, and the first symptom is a gate that groans and then stops latching. Stainless hardware is the fix, not a bigger keypad.
- Rot at the hinge post base on canyon-side wood gates. Redwood shade in Baltimore Canyon keeps the post bottom wet well into summer, and the rot starts underground before the panel shows any trouble. We dig, reset, and treat the footing when we rebuild.
- Binding swing arms on steep driveways. Larkspur’s canyon lots often run 10-15% grades, and standard articulated swing-gate arms bind at the end of the travel arc. The operator keeps pulling and the hinge post keeps taking the stress until something fails.
- Corroded operator control boards near the inlet. Salt air infiltrates the enclosure seals, and the board inside oxidizes until the gate stops responding to remotes or opens on its own. Sealed enclosures and conformal-coated boards are the coastal spec that lasts.
Key takeaways: Larkspur gate failures split along a micro-climate line: damp rot in the canyon, salt corrosion near the bay. Hardware and operator spec should match which side of the city you’re on. Steep driveways change the operator configuration that actually works. Written pricing and the 365-Day Done Right Promise come with every Larkspur job.
Pricing for Gate Repair in Larkspur, CA

Electric gate diagnostics start at $125, operator board replacements typically run $280 to $850, and a complete new automated gate installation lands between $2,800 and $7,500 depending on the gate type and operator.

FAQs About Gate Repair in Larkspur
Larkspur sits at the meeting point of two moisture environments: the redwood-canopied hillsides of Baltimore Canyon keep wood and iron damp year-round, while the bay side near the Corte Madera Inlet carries salt-laden marine air that corrodes mild steel aggressively. A gate in Larkspur is getting hit by rot, rust, or both, depending on which side of the city it sits on. This is why we spec stainless or galvanized hardware on bay-side properties and treated, wrapped post footings on canyon-side ones. Call (626) 649-4572 and we’ll tell you which environment your gate is in and what actually holds up there.
You usually need a hinge post repair, not a new gate. When the post rots at the base or the hinge barrel weld cracks, the gate leaf drops and the latch misses. We reset the post or weld the hinge barrel back to spec, and the gate squares up without replacing the panel. If the panel itself has rot through the rails, then a new gate makes sense, and we’ll tell you straight which one you’re looking at. Estimates are free, and the price is written before work starts.
On the bay side of Larkspur, use stainless steel hinge pins and fasteners, galvanized or stainless post bases, and sealed or conformal-coated control boards. Painted mild steel fails early in salt air, and even powder-coated steel will pit where the coating gets scratched during installation. We stock the stainless and galvanized hardware your gate needs because the marine air off the inlet doesn’t give standard parts much of a chance. Call (626) 649-4572 to get the right spec on your gate.
The bind is usually the swing-arm geometry fighting the grade. Larkspur canyon driveways often run 10-15%, and standard articulated swing arms bind at the end of their travel arc, which overloads the operator and stresses the hinge post. The long-term fix on these lots is switching to a sliding gate with a rack-and-pinion operator or a linear-actuator arm, and resetting the post so there is no deflection under load. We’ve done this on Baltimore Canyon driveways where the gate now runs clean on a 12% grade.
Yes, automatic gate operators in Larkspur are required to meet UL 325 safety standards, which include photo eyes or contact edges that reverse the gate when something is in the path. California also has statewide entrapment protection rules, and Marin County enforces them on new and serviced installations. When we repair or install an automatic gate in Larkspur, we test the safety reverse and the photo eye alignment before we leave, and we’ll tell you in writing if an older system needs a sensor retrofit to be safe. Call (626) 649-4572 for a free on-site check.
