Fast, Reliable Gate Repair Across San Martin
Gate repair in San Martin typically runs $180–$650 depending on whether we’re resetting a shifted post, welding a cracked hinge, or replacing a burned-out opener, and most jobs are completed same-day or next-day. We keep parts stocked for the heavy dual-leaf swing gates that dominate San Martin’s ranch and equestrian properties, so we’re not ordering components from San Jose while your driveway sits blocked.
We’re Granite Gate Repair California, and we’ve been driving out to San Martin from our San Jose base for 14 years. Louis Barrera and our team know the territory: long gravel driveways off Watsonville Road, horse properties near the Uvas Creek corridor, and the custom ranch homes tucked along Monterey Road. San Martin isn’t a quick in-and-out stop for us. It’s a distinct market with distinct problems, mostly rooted in the clay soils that run through the Santa Clara Valley floor and the oversized gates that property owners need to move daily farm and trailer traffic through.
If your gate is dragging, your opener is grinding, or your post has tilted another inch since last winter, call us at (888) 416-1369. We’ll diagnose it on-site and give you a free, upfront estimate before any work starts.
Why Granite Gate Repair California Is San Martin’s Preferred Gate Repair Company
San Martin homeowners don’t need a handyman who “also does gates.” They need someone who understands why a 16-foot dual-leaf tubular steel gate on a horse property fails differently than a suburban single-leaf aluminum gate. We’ve built our reputation on that difference.
Our 197 verified reviews average 4.7 stars, and a significant share come from repeat customers in the South Valley, including San Martin property owners who’ve learned that post-heave isn’t a one-time fix—it’s a cycle that demands the right footing and drainage from the start. Louis Barrera, our Founder and Master Technician, still runs field calls personally. When you call Granite Gate, you’re not getting dispatched to a subcontractor who might have seen three gate jobs this month.
Response time to San Martin is typically same-day or next-morning, depending on call volume and whether we’re already in the Morgan Hill or Gilroy corridor. We carry FAAC, BFT, and Linear parts on our trucks, plus our own welding rig, so most repairs don’t require a return trip.
We also understand the local permitting reality: San Martin’s unincorporated status means no municipal building department enforces gate opener codes. Homeowners often install under-powered residential openers on heavy dual-leaf swing gates, leading to chronic opener burnout and gear-strip failures that a commercial-grade FAAC or BFT unit would prevent. We flag this mismatch during every service call. It’s saved San Martin customers from replacing the same stripped actuator every two years.
Our Gate Repair Services in San Martin
Hinge Repair
San Martin’s heavy ornamental iron and tubular steel gates stress hinges beyond what standard residential hardware can handle. When clay-soil heave shifts your post even slightly, the gate leaf torques against the hinge barrel. We’ve replaced seized and cracked hinges on properties along Llagas Road and rebuilt custom weld-on hinge plates for gates that no standard bracket fits. Typical hinge repair in San Martin runs $180–$320.
Post Repair
This is our most frequent call in San Martin, and for good reason. The wet-dry clay-soil cycle here pushes posts out of plumb year after year. We don’t just shim and hope. We excavate, re-set the post in a 24-inch-deep concrete footing with a gravel drainage sleeve, and realign the gate to the corrected post. On a horse property off Watsonville Road, we replaced a burned-out residential linear actuator on a heavy tubular-steel dual-leaf gate with a FAAC 740 hydraulic swing operator. The original opener had stripped its nylon gears trying to push the gate against a post that had shifted 2 inches out of plumb from clay-soil heave—a problem we fixed by re-setting the post properly. Post repair and re-footing in San Martin typically costs $350–$650.
Weld Repair
Most gate companies outsource welding. We don’t. Our mobile rig lets us repair cracked gate frames, broken latch tabs, and fatigued hinge mounts on-site. San Martin’s ranch gates see abuse from livestock, equipment, and trailers that suburban gates never encounter. A cracked weld left unattended turns into a full gate replacement. We catch it early. Weld repairs generally fall between $200–$400 depending on access and material thickness.
Gate Realignment
Realignment without post repair is sometimes a temporary fix, and we’re honest about that. But when the post is still sound and the gate has simply sagged or shifted on its hardware, we can restore proper swing geometry, latch engagement, and opener synchronization in a single visit. For San Martin’s dual-leaf gates, this includes resetting the center gap so the leaves don’t bind or scrape. Realignment service runs $180–$300.

Trusted Brands We Service in San Martin
Your brand, our specialty. We service and stock parts for nine major automation brands, and in San Martin we see FAAC, BFT, and Linear most often on the heavier swing-gate installations. FAAC’s hydraulic operators and BFT’s electromechanical systems handle the torque demands of San Martin’s dual-leaf ranch gates far better than the residential-grade openers many properties were originally fitted with. We carry common FAAC and BFT control boards, limit switches, and gear sets on our trucks, which means faster turnaround for San Martin customers. If you’re running a Viking or Ghost Controls system on a lighter single-leaf gate, we service those too, and we’ll tell you honestly if your current opener is matched to your gate’s weight and duty cycle.
Common Gate Repair Problems We See in San Martin Homes
- Chronic post-footing failure from clay-soil heave. The South Valley’s expansive clay soils swell in winter rains and contract in summer drought, tilting posts and repeating the same misalignment every year. We address this with deeper footings and drainage sleeves, not just surface-level adjustments.
- Broken hinges from heavy dual-leaf gates sagging after post shift. Once a post tilts, the gate weight transfers unevenly to the hinge barrel. We’ve seen 3/8-inch hinge pins shear clean off on San Martin ranch properties where the post had shifted just two inches.
- Gear-stripped residential openers on gates requiring commercial-duty torque. Without municipal code enforcement, San Martin properties often have openers rated for 500 pounds pushing gates that weigh 800-plus pounds. The nylon gears strip predictably. We upgrade to properly spec’d FAAC or BFT commercial units.
- Wooden gate component warping from hot, dry summers. San Martin’s rainless July-through-September stretch dries and cracks wooden carriage-house gates, loosening joinery and throwing panels out of square. We treat, seal, and reinforce— or recommend steel framing behind wood facades.

FAQs — Gate Repair in San Martin
They don’t, if they’re set right the first time. The clay soils beneath San Martin expand when wet and shrink when dry, creating a seasonal heave cycle. Posts set in shallow concrete without drainage sleeves tilt repeatedly. We excavate to 24 inches, pour a proper footing, and add a gravel drainage layer to break the capillary action that causes swelling. Done this way, the fix lasts. Call (888) 416-1369 if your post has shifted again—we’ll show you why it keeps happening.
Yes, and we do it regularly. Modern FAAC and BFT operators integrate with Wi-Fi bridge modules and smartphone apps, letting you open your gate from the barn, the road, or your truck. We match the opener’s torque rating to your gate’s actual weight and duty cycle, not just add a smart module to an under-powered unit. For a free compatibility check on your specific gate, call (888) 416-1369.
Seal it before June, and inspect it every September. San Martin’s rainless summers pull moisture from wood, causing panels to shrink and joints to loosen. We recommend penetrating oil-based sealers over film-forming coatings, which trap moisture and peel. For gates already showing warp or joint failure, we can reinforce with concealed steel framing. Call (888) 416-1369 for a wood-gate assessment before next summer.
A commercial-grade hydraulic or heavy electromechanical operator, typically FAAC or BFT, rated for continuous duty and high torque. Residential openers fail quickly on the heavy dual-leaf gates common in San Martin, especially when gravel buildup adds rolling resistance. We spec for your gate’s weight, your driveway length (which affects access timing), and your daily cycle count. Get a proper spec by calling (888) 416-1369.
We grind to bare metal, treat with rust converter, weld-repair any pitting that has compromised structural integrity, and apply a two-part epoxy primer followed by an industrial enamel topcoat. Surface rust on San Martin gates is usually manageable; deep section loss from years of neglect may require panel or frame replacement. Early treatment saves money. Schedule a rust inspection at (888) 416-1369.
