Why Prime Gate Solutions Alameda Is San Lorenzo’s Preferred Gate Repair Company
We’ve been fixing gates in unincorporated Alameda County for nearly three decades, and San Lorenzo accounts for a significant share of our call volume — not because the gates are poorly built, but because they’re all aging out at once. Brian takes the call and does the work, so when you schedule with us, you’re getting 27 years of gate-specific experience on your property, not a subcontractor learning on the job.
Our 553 verified reviews average 4.9 stars, and San Lorenzo customers show up in that feedback consistently. They mention specifics: that we spotted the rotted post their previous handyman missed, that we had the right hinge in stock for a 1950s redwood gate, that we explained the Alameda County permit process before they got surprised by it. That’s the difference between a gate specialist and a generalist who treats gates as a side job.
Response time matters when your gate won’t close and your dog’s in the yard or your driveway’s exposed. We’re typically on-site in San Lorenzo within the hour for standard calls, and we carry parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule systems — meaning most opener repairs finish in one visit. We also handle Gate Repair in San Lorenzo properties from the flatlands near San Lorenzo Creek up to the slightly elevated tracts off Lewelling Boulevard, so we know the microclimates that affect your hardware.
Our Gate Repair Services in San Lorenzo
Hinge Repair
San Lorenzo’s salt air chews through mild-steel hinges faster than almost anywhere we work in Alameda County. The marine layer rolls in off San Francisco Bay, settles on exposed metal, and within three to five years a standard hinge can corrode to the point of gate sag or complete failure. We replace failed hinges with galvanized or stainless hardware rated for coastal exposure, and we check the gate’s weight distribution — because a hinge that failed prematurely often indicates the gate has shifted on a rotting post or the frame has twisted from rust.
Post Repair
This is the big one in San Lorenzo. The Bohannon Development Company set millions of redwood and cedar fence posts directly in soil back in the 1940s through 1960s, and after eighty years of absorbing marine moisture, those posts are rotting at ground level across entire neighborhoods. We excavate the failed post, install a galvanized steel anchor or replace with pressure-treated lumber set on a concrete footing, and realign the gate to proper swing geometry. Because so many San Lorenzo lots share identical original construction, we can often diagnose post failure from the street — but we always verify with a physical inspection.
Weld Repair
When a gate frame cracks at the weld or a decorative iron element separates, general handymen typically punt to an outside welder and leave you waiting. We don’t. Our in-house welding capability means we repair steel and aluminum gate frames on-site, match existing welds for appearance, and get your gate operational same-day. In San Lorenzo, we see a lot of wrought-iron side gates on Bohannon homes that have fatigued at stress points after decades of salt-air exposure — we grind, prep, weld, and coat in one trip.
Gate Realignment
A gate that drags, binds, or won’t latch usually isn’t the gate’s fault — it’s the structure it hangs from. In San Lorenzo, realignment work follows post repair about sixty percent of the time. We check plumb, level, and swing arc; shim or rebuild the hanging hardware; and adjust or replace the latch mechanism. If your gate has an automatic opener, realignment is critical — a dragging gate burns out motors, strips gears, and snaps chains. We fix the root cause so your opener doesn’t become the next casualty.
Lock Repair & Rust Treatment
Lock seizure from internal rust is epidemic in coastal San Lorenzo. We disassemble, clean, lubricate, or replace lock mechanisms, and we apply rust-inhibiting treatments to hardware that still has structural life. For gates with significant surface rust but sound underlying metal, we wire-brush, treat with phosphoric acid converter, and finish with a rust-inhibiting coating — extending service life by years in this environment.

Our factory familiarity covers LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule operators and access control systems.

Whether your opener’s a decade-old Mighty Mule on a backyard gate or a commercial-grade FAAC system for an HOA on Hesperian, we diagnose and repair without the trial-and-error you get from multi-trade contractors.
Common Gate Repair Problems We See in San Lorenzo Homes
- Rotted redwood posts at ground level. The Bohannon-era standard of setting posts directly in soil — no concrete footing, no post anchor — means San Lorenzo’s original fence posts are failing in clusters across entire blocks. We replace with modern anchoring that isolates wood from soil moisture.
- Hinge and latch corrosion from salt air. San Lorenzo’s proximity to the Bay and San Lorenzo Creek delivers persistent humidity that pitts mild-steel hardware. Stainless replacements are the fix, not more of the same.
- Automatic opener premature failure. Circuit boards corrode, chains rust and kink, gears pit from moisture ingress. We see five- to seven-year opener lifespans here versus ten to fifteen inland — and we specify coated chains and sealed housings on replacements.
- Gate sag causing opener strain. When the post rots or the hinge corrodes, the gate drops. The opener works harder, overheats, and fails. We fix the structural problem first, then address the opener — never the reverse.

San Lorenzo’s Unique Gate Repair Challenge: The Bohannon Legacy Meets the Bay
San Lorenzo was built almost entirely as a planned postwar suburb by the Bohannon Development Company starting around 1944, meaning the residential housing stock — and the original wooden fence posts and gate hardware installed with it — dates overwhelmingly to the late 1940s through 1960s and is aging out simultaneously across the neighborhood. Combined with persistent marine moisture from nearby San Francisco Bay accelerating rust on hinges, latches, and automatic openers, gate repair here is dominated by a community-wide, concurrent failure of mid-century infrastructure that creates concentrated, recurring demand unlike piecemeal aging seen in more mixed-vintage cities.
We were called to a Bohannon-era ranch home on Via Estrada where the original 1950s redwood fence gate had rotted at the post base and the mild-steel hinge had corroded through from years of salt air. We installed a galvanized steel post anchor, stainless hinge, and a nylon roller on the swing gate, then replaced the corroded opener chain with a coated one. The homeowner had no idea their cast-iron latch was next to fail until we pointed out the rust scaling — something we see on every San Lorenzo job.
Because San Lorenzo is unincorporated Alameda County rather than an incorporated city, gate and fence permits are processed through the Alameda County Planning Department — not a local city building department — a procedural detail that routinely surprises homeowners and that knowledgeable local gate techs flag at the estimate stage to prevent project delays. We bring this up during our first conversation, because nothing derails a timeline like discovering permit requirements after work has started.
We Also Serve Cities Near San Lorenzo
Our service radius extends naturally from Hayward to cover the surrounding unincorporated and incorporated communities. We regularly repair gates in Ashland along the MacArthur Boulevard corridor, San Leandro from the Washington Manor neighborhoods to the industrial properties near the marina, Cherryland with its similar Bohannon-era housing stock, and Castro Valley where the slightly more inland elevation means marginally slower corrosion rates but many of the same mid-century construction patterns. If you’re unsure whether you’re in our service area, call (510) 616-4869 — we know the local boundaries and permitting authorities for each.

FAQs — Gate Repair in San Lorenzo
Most simple repairs — hinge replacement, latch adjustment, opener troubleshooting — don’t require permits. However, because San Lorenzo is unincorporated Alameda County, any work involving new post installation, structural modification, or height changes must go through the Alameda County Planning Department, not a city building office. We flag this during our estimate so you’re never surprised by a stop-work order. Call (510) 616-4869 and we’ll walk through whether your specific job needs permitting.
San Lorenzo’s location close to San Francisco Bay and San Lorenzo Creek means consistent marine layer humidity and mild salt air penetrate the neighborhood, corroding mild-steel hinges, latches, and automatic gate operator components significantly faster than in inland Alameda County communities like Castro Valley or Livermore. We replace with stainless or galvanized hardware rated for coastal exposure. For a rust assessment on your gate, call (510) 616-4869 — estimates are free.
On a Bohannon-era San Lorenzo home, sagging almost always means the redwood or cedar post has rotted at ground level from decades of soil contact and moisture absorption. The hinge side drops, the gate drags, and the latch no longer aligns. We replace the post with modern anchoring and realign the gate to proper swing geometry. Call (510) 616-4869 — we can confirm the diagnosis and quote repair on-site.
Yes — mid-cycle stopping usually indicates either a failing safety sensor, a motor overheating from gate drag, or internal corrosion in the control board or limit switches. In San Lorenzo’s humid environment, we see all three frequently. We diagnose the root cause rather than replacing parts blindly, and we fix the underlying gate alignment or hardware issue that’s stressing the opener. Call (510) 616-4869 for same-day troubleshooting.
We service and stock parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule systems — covering virtually every residential and light-commercial gate operator in the San Lorenzo market. Because we specialize exclusively in gates, we carry failure-prone components like circuit boards, gear assemblies, and remote receivers that general repair shops don’t stock. Call (510) 616-4869 with your model number for parts availability.
