Gate Repair in San Lorenzo, CA
Gate repair in San Lorenzo typically costs $180–$650 depending on whether you’re dealing with rusted hinges, rotted posts, or a motor that quit, and most jobs we can reach within 45 minutes. If your gate is sagging, scraping the driveway, or the opener stopped responding after last week’s rain, call us at (888) 416-1369 for a free estimate. Louis and the Granite Gate team know San Lorenzo’s neighborhoods well — from the original Bohannon tract homes off Hesperian Boulevard to the creek-side properties where clay soil shifts posts every wet season — and we carry the parts to fix most gate issues same day.
Why San Lorenzo Homes Are Different
San Lorenzo was built almost entirely as David Bohannon’s planned community between 1944 and 1952, which means the residential housing stock is unusually uniform in age. The original wood and chain-link gates installed during that single construction wave are now 70–75 years old and failing at scale across the neighborhood simultaneously. San Lorenzo sits closer to the bay than inland Hayward, trapping persistent morning marine layer and higher humidity that corrodes metal hardware faster and rots wood posts at grade level. Properties near San Lorenzo Creek or the flood-control channel face additional seasonal ground saturation that shifts posts and throws gates out of square every winter — a pattern we’ve tracked through 14 years of service calls here.
Gate Repair in San Lorenzo
Gate repair in San Lorenzo is less about one-off fixes and more about addressing a community-wide cohort of aging, same-era installations. Because Bohannon-era posts were set directly in clay soil without concrete footings, we see synchronized failures across entire blocks — neighbors on Via Alamosa or Via Encinas calling within months of each other with identical post rot. Our Gate Repair service includes full structural assessment before any hardware work, because fixing a hinge on a leaning post is a guaranteed callback by March.
Post Repair
Post repair is our most frequent call in San Lorenzo, and there’s a reason. The original wood posts on Bohannon-era homes were set directly in clay soil with no concrete footing. Seventy-five years of ground contact and San Lorenzo’s persistent humidity have rotted them six inches below grade. We excavate the old post, pour a proper concrete boot below the frost line, and set a pressure-treated or steel post that won’t shift when the clay expands every winter. A typical post repair in San Lorenzo runs $280–$450 per post.
Gate Realignment
Your gate worked fine in October. By March it’s dragging, the latch won’t catch, and the gap under the frame has disappeared. This is the San Lorenzo Creek clay cycle — saturated soil swells, dry summer shrinks it back. We see this on properties from Ashland Avenue to the flood-control channel corridor. Our realignment service includes checking post plumb, adjusting hinge placement, and sometimes relocating the latch strike to compensate for seasonal movement. We also assess whether the post itself is the root cause. Gate realignment in San Lorenzo typically costs $180–$320.
Why do my San Lorenzo gate posts rot so quickly?
Your posts rot fast because the original 1940s installation used wood set directly in clay soil with no concrete footing, and San Lorenzo’s persistent humidity from the marine layer accelerates decay at ground level. Properties near San Lorenzo Creek see even faster rot from seasonal ground saturation. We replace with pressure-treated or steel posts set in concrete boots below the frost line, which stops the cycle. Call (888) 416-1369 for a free inspection.
Gate Installation in San Lorenzo
Gate installation in San Lorenzo typically runs $2,800–$6,500 for a complete residential system with operator, and most projects finish in two to three days once materials arrive. San Lorenzo isn’t like neighboring Hayward or Castro Valley — the Bohannon-era lot layouts with narrow post spacings and low fence heights require custom fabrication that standard gate companies can’t handle in-house. Louis Barrera measures every opening personally before ordering materials, and we fabricate frames on-site to fit openings that haven’t been standard since 1952. Our Gate Installation service covers everything from single pedestrian gates to full driveway automation.
Swing Gate Installation
Swing gates remain the most common replacement we install in San Lorenzo’s original neighborhoods, where narrow driveways and modest setbacks make them the practical choice. We replaced a rotted wooden swing gate off Via Alamosa where the original 1940s cedar post, set in soil without concrete, had pulled 3 inches out of square during a wet-season ground shift. We installed a new wind-rated steel swing gate with a DoorKing 9600 operator and concrete-footed posts to withstand San Lorenzo Creek corridor ground saturation and bay gusts. Single swing installations with operator typically run $5,500–$8,500.
Pedestrian Gate Installation
The original pedestrian gates in San Lorenzo’s Bohannon tracts were simple wood frames with basic latches, often sharing fence posts with the perimeter chain-link. Those shared posts are now failing simultaneously — rot at grade, rusted fasteners, and wobbly frames that won’t close square. We install standalone pedestrian gates with dedicated steel posts and self-closing hinges rated for coastal humidity. Manual pedestrian gates in steel or aluminum typically cost $2,800–$4,200 installed.
Do I need a permit for a new driveway gate in San Lorenzo?
Yes, Alameda County requires permits for new driveway gates in unincorporated San Lorenzo, with specific requirements for swing clearance, visibility, and emergency access that differ from incorporated city rules. We handle permit research as part of our installation planning and can advise whether your specific location falls under county or any special district jurisdiction. Call (888) 416-1369 and we’ll verify the requirements for your address.
Gate Motor & Opener in San Lorenzo
Gate motor repair in San Lorenzo typically runs $280–$620 and most jobs finish same-day when the post structure is sound. The Bohannon-era housing stock creates unique motor challenges: original posts without concrete footings shift in wet clay, racking the gate and burning out openers that strain against misalignment. We’re not a general handyman shop guessing at gate problems — Louis Barrera specs motors to actual gate weight and wind load, not just opening width. Our Gate Motor & Opener service covers nine major brands with in-house parts inventory.
Motor Repair
Most motor repairs in San Lorenzo fall between $280–$550. Common issues here: limit switches thrown out of calibration by gate rails binding on shifted posts, circuit boards corroded from persistent morning fog, and actuator rods pitted from salt-air exposure. We don’t just swap the motor. We trace why it failed. On a property near the flood-control channel last March, we found a Linear actuator with a perfectly good motor but a mounting bracket cracked from post heave. Fixed the post, saved the motor, and the gate tracked straight through the next wet season.
Linear Motor Service
Linear motors are popular on San Lorenzo’s narrower side-yard gates where a swing arm won’t fit. Repair or replacement typically costs $340–$680. The marine layer is hard on these — the exposed actuator rod collects condensation, and without regular maintenance the seal fails and grit scores the shaft. We service Linear brand units in-house and stock replacement actuators and control boards. For gates near the creek corridor, we recommend sealed rod covers and annual lubrication checks; the humidity here is measurably higher than in inland Ashland or Cherryland, and it shows in the failure patterns.
My San Lorenzo gate opener keeps tripping the limit switch after the winter rains. Is that normal here?
Yes, it’s common in San Lorenzo, especially creek-proximate properties where clay soil saturates and shifts gate posts. The gate geometry changes slightly, the opener hits its programmed travel limits early, and the safety circuit trips. The fix isn’t recalibrating the motor repeatedly — it’s addressing the post shift, then resetting limits. Call (888) 416-1369 and we’ll inspect the footing; estimates are free.
Gate Access Control in San Lorenzo
Gate access control repair and installation in San Lorenzo typically runs $450–$1,850 depending on whether we’re retrofitting aging 1940s hardware or installing new smart systems on updated posts. Most San Lorenzo homeowners call us when their original keypad or latch finally gives out after 70-plus years of service. The narrow post spacings and low fence heights of Bohannon-era lots don’t accommodate standard modern access hardware without custom adaptation — something we handle in-house rather than walking away from. Our Gate Access Control service integrates with your existing or new gate automation.
Keypad Entry Systems
Keypad entry in San Lorenzo presents a specific challenge: the original 1940s posts and narrow spacings weren’t designed for modern units. A typical keypad installation here runs $380–$650, but we often find the mounting surface itself needs reinforcement first. On properties near San Lorenzo Creek, we’ve learned to spec marine-grade hardware because standard keypads corrode faster in this humidity. We install LiftMaster, DoorKing, and FAAC keypads with weather-sealing appropriate to this microclimate.
Remote Control Systems
Remote programming and receiver replacement for San Lorenzo’s older gates starts around $220–$400. The real issue we encounter isn’t the remote itself, it’s the gate condition. A sagging, binding gate from 1950 will burn through remotes and motors alike because the operator strains against misalignment. We’ll tell you straight if your remote problems are actually a gate geometry problem, and we’ll fix that first so you’re not replacing remotes twice a year.
Can you repair a 1940s keypad entry system?
No. Original 1940s keypad and intercom systems are obsolete with no available parts, and we don’t recommend hunting salvage units that will fail similarly. We retrofit modern access control, spec’d for San Lorenzo’s narrow post spacings and low fence heights, with hardware that fits the period aesthetic without looking anachronistic. A typical retrofit with new keypad on reinforced posts runs $580–$950. Call (888) 416-1369 for a free assessment of what’s possible with your gate.
Gate Parts & Welding in San Lorenzo
Gate parts and welding repair in San Lorenzo typically costs $180–$650 depending on whether you’re replacing hinges, welding a cracked frame, or setting a new post with proper footing. Most jobs in the 94580 ZIP code are completed same-day or next-day. Here’s what sets us apart from every other gate company in this market: we don’t haul your gate to an outside welder and make you wait. Louis brings portable welding equipment to the job and fabricates brackets, hinge mounts, and rail sections on-site. Our Gate Parts & Welding capability eliminates the middleman markup and delay most competitors hide.
Hinge Replacement
Standard galvanized hinges last about five years in San Lorenzo’s salt-heavy marine layer before seizing or shearing. We see this constantly in the Village, where original 1940s steel hinges have corroded to orange dust. We stock stainless steel and bronze alternatives rated for bay-adjacent humidity. A typical hinge replacement in San Lorenzo runs $180–$280 for a single gate, including removal of the seized hardware and alignment check.
Post Replacement
This is the repair we perform most often in San Lorenzo, and it’s never a simple swap. The original Bohannon-era gates were built with wood posts set directly in clay soil without concrete footings, a construction defect that now causes universal post rot and gate sag across the 70+ year-old stock. Every repair in the Village or Hillside neighborhoods must start with a post-inspection before touching the hardware. We excavate the rotted post, set a new pressure-treated or steel post with a concrete collar extending 6 inches above grade, and realign the gate frame. Post replacement with concrete footing typically runs $350–$650.
Should I replace my old steel hinges with stainless steel for San Lorenzo’s humidity?
Yes, if you plan to keep the gate more than three years. Standard galvanized hinges corrode and seize within five years in San Lorenzo’s bay-adjacent humidity, while stainless steel or bronze hinges withstand the marine layer indefinitely. The upfront cost difference is roughly $40–$80 per hinge pair, but you’ll avoid the frame damage that occurs when a seized hinge forces the opener to twist the rail. We stock both options and can show you the difference on your estimate.
Brands We Service in San Lorenzo
We service and install nine major gate automation brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For San Lorenzo’s wet microclimate, we particularly recommend Linear and DoorKing components with sealed enclosures, and we carry common parts for same-day repair on these brands. Most brand-specific repairs don’t require ordering from a warehouse — Louis stocks what fails most often in bay-adjacent conditions. See all brands we service.

What San Lorenzo Customers Say
"We had a hydraulic arm leaking fluid onto the driveway. Replaced, cleaned up the stain as best he could, and it's been dry for months."
— Nabil Khalil"Fixed the immediate problem. He was honest that the operator is near end of life and I should budget for a replacement, which I appreciate even if it wasn't what I wanted to hear."
— Scott Mercer"Solar panel on our remote gate wasn't keeping the battery up through the winter. He repositioned it, replaced the battery, and explained the math on why the old placement was never going to work."
