Why Calder Gate Repair Is Tiburon’s Preferred Gate Repair Company
Tiburon homeowners have a specific frustration with gate companies: vague arrival windows, prices that change at the door, and repairs that last a season. We built our process around the opposite. Every Calder job in Tiburon comes with the Relay Standard: a live arrival time you can track on your phone, before-and-after photos of the work, and a digital invoice you pay from a link. Nothing gets bolted on that wasn’t in the written quote.
Nico Alvarez, who leads our team, lives and breathes automatic gate systems. He’s trained our technicians across nine major opener brands, so the person who arrives at your Tiburon driveway has likely already fixed a dozen gates like yours this month. That depth matters when a hillside gate has three problems stacked on top of each other.
We also back every repair with the 365-Day Done Right Promise. If the repair fails within 365 days, we return at no charge. That’s in writing, on every job, no fine print.
Iron Gate Repair in Tiburon
Iron Gate Repair in Tiburon usually means one of three things: a sagging leaf that drags on the driveway, a hinge or post that’s loosened, or rust and weld fatigue that’s compromised the frame. On Tiburon’s hillside lots, the sagging leaf is by far the most common. Much of Tiburon’s hillside housing stock sits on steep, cut-bank driveways where a swing gate’s hinge post footing has to be set deep on the downhill side or the gate will lean and sag within a season. That sloped-footing condition drives more sag-correction and post-reset calls here than the flat-lot gate failures typical of the rest of Marin.
A basic iron gate realignment in Tiburon runs $350 to $650. If the hinge post itself has shifted and needs to be reset in a deeper footing, expect $700 to $1,200 including concrete work and re-hanging the leaf. Weld repairs on cracked iron frames run $150 to $450 per section depending on access and steel thickness.
Post and Hinge Resets on Sloped Driveways
On a hillside driveway in Tiburon, a hinge post set too shallow on the downhill side will eventually lean, and the gate leaf follows it. We reset the post deeper, backfill with proper concrete, and re-hang the gate so it clears the driveway edge again. Then we re-tune the opener so the travel limits match the corrected geometry.
Rust and Weld Repair Work
Salt air off the Bay accelerates rust on iron gates throughout the Tiburon peninsula, especially within a mile of the shoreline. We grind back rust, weld reinforcement where the frame has thinned, and re-prime and paint the repaired sections so they don’t fail again next season.
Sliding Gate Repair in Tiburon
Sliding Gate Repair in Tiburon tends to involve track problems, roller failures, or the operator struggling to move a gate that’s out of level. Sliding gates are less common on Tiburon’s steep driveways than swing gates, but they show up on flatter parcels near Belvedere and along Paradise Drive where lot geometry favors a sliding leaf. When they fail, it’s usually because debris in the track or a seized roller is making the motor work against friction it wasn’t built for.
Typical sliding gate repair work in Tiburon runs $225 to $500 for roller and track service. If the operator itself has failed and needs replacement, that’s $650 to $1,400 installed depending on the brand and horsepower required for the gate’s weight.

Track Cleaning and Roller Replacement
Tiburon’s rainy winters push leaves, mud, and gravel into sliding gate tracks, especially on driveways that slope toward the street. We clear the track, replace seized rollers, and check the end stops so the operator isn’t fighting the gate on every cycle.
Operator Replacement on Existing Sliding Gates
When a sliding gate opener fails, we don’t just swap boxes. We check the gate’s weight, the track alignment, and the power supply, then recommend an operator rated to move that specific gate. The written quote covers the operator, mounting hardware, and setup, so you know the full number before we touch a wrench.
Trusted Brands We Service in Tiburon
Tiburon gates run on a mix of brands, and we’re factory-familiar with the ones we see most often out here: FAAC operators on Mediterranean-style swing gates, BFT units on newer automatic installations, Linear openers on mid-century properties, and Viking systems on larger estate gates. We carry common control boards, limit switches, and remote transmitters on our trucks, so a Tiburon repair doesn’t stall while parts ship from a warehouse. If we need something uncommon, we source it same-week and keep you posted on timing with a live update from a real person.
Common Gate Repair Problems We See in Tiburon Homes
- Swing gate sagging at the hinge post. The footing was set shallow on a sloped hillside driveway, and the downhill edge of the gate has dropped until it scrapes. We reset the post, correct the sag, and re-level the gate before re-tuning the operator.
- Gate operator stalling on an incline. An undersized operator or dead batteries in a solar gate opener can’t move a heavy gate uphill. We check the motor rating against the gate’s actual weight and slope, then recommend the right fix. Safety note: gate motors and springs under tension can cause serious injury. If your operator is stalling or misbehaving, don’t try to force the gate manually; call a trained professional.
- Safety sensor failures going unnoticed. Older Tiburon gates that predate current UL 325 entrapment-protection expectations often lack working photocells and reversing edges. We test these on every visit because a gate that can’t detect a car, a dog, or a person in its path is a liability, not just an inconvenience.
- No power run to the gate. Some Tiburon properties have a gate at the street with no trench for electrical, so the opener runs on solar and batteries. When the batteries age out, the gate opens slowly or not at all. We can replace solar battery banks and check panel output to keep the system viable.

FAQs About Gate Repair in Tiburon
Sometimes yes, but not usually. A sagging gate in Tiburon is almost always a footing problem, not a hinge problem. If the hinge post has shifted on a sloped driveway, adjusting hinges buys you weeks at best. A proper fix means resetting the post in a deeper footing, re-hanging the gate, and re-tuning the operator. That runs $700 to $1,200 in Tiburon. Call (903) 417-0793 and we’ll tell you honestly which fix your gate needs.
For a new automatic gate on a Tiburon hillside property, plan on 2 to 5 days of on-site work depending on ground conditions, gate size, and power availability. That includes post footings, gate hanging, operator mounting, safety sensor installation, and reversal testing. We never promise same-day turnaround on an installation. We measure, quote a written price, order materials, and schedule a firm start date. Call (903) 417-0793 for a free measure and written estimate.
Yes. Under UL 325 entrapment protection standards, automatic gate openers are required to have at least two forms of entrapment protection, typically photocells on either side of the gate and a reversing edge or inherent motor reversal. Many older Tiburon gates predate these requirements and lack working sensors. We test sensors on every service call and can retrofit protection to bring an older gate up to current standards. This is a genuine safety issue, not a paperwork formality.
We repair both, and we repair far more gates than we replace. Our Tiburon work includes iron gate realignment, hinge and post resets, weld and rust repair, sliding gate track and roller service, and operator replacement on existing gates. Full installations are part of our scope too, but if your gate can be properly fixed, we’ll tell you that first and quote the repair honestly. Call (903) 417-0793 to describe your gate and get a straight answer.
Yes, and plenty of Tiburon properties run solar gate openers because trenching power down a steep driveway is expensive and destructive. The catch is battery health. Tiburon’s foggy summer mornings and short winter days mean solar panels charge fewer hours than inland, so battery banks age faster. We replace solar batteries, check panel output, and can upgrade panels or add a second panel where tree cover blocks light. Battery replacement runs $280 to $520 in Tiburon. Call (903) 417-0793 and we’ll check your setup before recommending anything.
