Fast, Reliable Gate Parts & Welding Across San Lorenzo
Gate parts and welding repair in San Lorenzo typically runs $180–$650 depending on whether you’re replacing a hinge, rebuilding a rotted post, or fabricating custom brackets for a heavy detached-workshop gate. Most jobs are completed same-day because our Gate Parts & Welding team carries the specific hardware and steel stock San Lorenzo’s aging gate stock demands. We’re Gate Parts & Welding in San Lorenzo regularly — from the Bohannon-era ranch homes along Via Alamitos to the acreage properties near San Lorenzo Creek — and Brian Robinson handles the fieldwork personally, so you’re getting 27 years of gate-only experience on every call, not a subcontractor learning your property on the fly.
Why Prime Gate Solutions Alameda Is San Lorenzo’s Preferred Gate Parts & Welding Company
San Lorenzo’s gate problems aren’t generic, and neither are our fixes. The 553 customers who’ve left us a 4.9-star average rating include plenty of your neighbors — HOA managers along Hesperian Boulevard, homeowners in the original Bohannon tracts, and small commercial property owners near Lewelling Boulevard — who needed someone who understands why a 1950s redwood post rots differently than a modern pressure-treated one.
Brian takes the call and does the work. That means when you describe a gate that’s sagging into the driveway off Via Alamitos, he’s the one who shows up with the right steel stock, the right concrete footing specs, and the knowledge that San Lorenzo’s unincorporated status routes permits through Alameda County Planning — not a city department — so your project doesn’t stall on paperwork you didn’t know existed.
Our response time to San Lorenzo averages under 45 minutes from dispatch because we’re based in Hayward and know the back routes through Ashland and Cherryland. For a community where gate failures often mean a vehicle can’t access a workshop or backyard, that matters.
We’re gate specialists, not generalists. That focus means we stock parts for 9 major brands — LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule — and we weld custom solutions on-site instead of ordering brackets that may or may not fit your mid-century frame.
Our Gate Parts & Welding Services in San Lorenzo
Post Replacement
Post replacement is the most common gate parts job we do in San Lorenzo, and there’s a specific reason why. The Bohannon Development Company built this suburb fast and uniform — redwood or cedar posts set directly in native soil, no concrete footing, standard practice for 1940s–1960s tract construction. Seventy years later, that soil contact has turned solid posts to punk. We replace with pressure-treated 4x4s or 6x6s on concrete footings below frost line, and because San Lorenzo’s marine moisture accelerates decay, we spec ground-contact-rated lumber with post-base hardware that keeps wood out of direct soil. Typical post replacement in San Lorenzo runs $280–$480 per post, including removal, concrete, and hardware transfer.
Custom Welding & Fabrication
San Lorenzo’s acreage properties and detached workshops often have gates heavier than any off-the-shelf bracket was designed for. We weld custom gusseted hinge plates, reinforced latch strikes, and modified operator arms on-site — no waiting for a fabrication shop across the Bay. Our field rig handles mild steel, stainless, and aluminum, and Brian specs materials for the salt-air exposure that comes with San Lorenzo’s proximity to the Bay. A custom-fabricated heavy-duty hinge assembly typically runs $320–$550 installed, depending on steel grade and welding complexity.
Hinge Replacement
Marine layer humidity doesn’t just make mornings foggy — it keeps mild-steel hinges perpetually damp, especially on north-facing gates that never see afternoon sun. We replaced a heavy-duty swing gate hinge assembly and upgraded to a ¾-horsepower LiftMaster opener on a detached workshop off Via Alamitos. The original mid-century set-screw hinges had fatigued from decades of marine moisture, and the homeowner wanted a single-trip fix that could handle the oversized door. Standard hinge replacement in San Lorenzo runs $180–$340; upgrading to marine-grade stainless or galvanized hardware adds $40–$80 but pays for itself in lifespan.
Rail Repair & Gate Rollers
Sliding gates on San Lorenzo’s sloped lots — common near the creek drainage — put lateral stress on bottom rails and roller assemblies. We straighten bent steel, replace seized V-groove or cantilever rollers, and realign track for smooth operation. Rail repair with roller replacement typically runs $220–$420.

Trusted Brands We Service in San Lorenzo
We work on your brand — whatever’s on your gate right now. Our service van stocks common wear parts for LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule operators, plus generic hardware that fits most mid-century San Lorenzo installations. That inventory means most San Lorenzo customers get same-day resolution instead of a return trip after parts are ordered. For the aging original openers we see regularly in Bohannon-era homes, we source compatible replacement components or advise honestly when a modern operator is the smarter investment.
Common Gate Parts & Welding Problems We See in San Lorenzo Homes
- Rotted posts at ground line. The 1940s–1960s practice of setting redwood or cedar directly in soil — standard across San Lorenzo’s Bohannon tracts — creates predictable failure. We see this on virtually every street from Via Alamitos to the Hesperian corridor, and full replacement with concrete-footed posts is the only lasting fix.
- Corroded hinges and latches from marine moisture. San Lorenzo’s Bay-adjacent climate delivers consistent humidity and mild salt air that inland Castro Valley simply doesn’t experience. Mild-steel hardware rusts faster here; we spec galvanized or stainless replacements that survive the fog cycles.
- Undersized openers on heavy workshop gates. Acreage properties with detached workshops often have solid-core wood or steel gates that original ¼-horsepower operators strain to move. The resulting gear wear or motor burnout is a symptom, not the root problem — we upgrade to properly specced operators with custom-welded mounting brackets.
- Permit confusion from unincorporated status. Because San Lorenzo is unincorporated Alameda County, gate and fence permits go through the Alameda County Planning Department, not a city building department — a detail that surprises homeowners and can delay projects if not flagged early. We walk customers through this at the estimate stage so work starts on schedule.

FAQs — Gate Parts & Welding in San Lorenzo
Yes, if the replacement involves a fence line over 6 feet tall or a structural gate post supporting an automatic operator. Because San Lorenzo is unincorporated Alameda County, 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. Call (510) 616-4869 and we’ll confirm whether your specific job requires permitting and handle the paperwork if it does.
San Lorenzo’s proximity to San Francisco Bay and San Lorenzo Creek means persistent marine layer humidity and mild salt air that penetrates the neighborhood year-round — conditions Castro Valley’s inland location simply doesn’t experience. North-facing gates are especially vulnerable since they never fully dry between fog cycles. We spec galvanized or stainless hardware for San Lorenzo installations that lasts 3–4 times longer than standard mild steel in this climate. Call (510) 616-4869 for a free hinge assessment — estimates are free.
Yes, custom welding for heavy-duty applications is a core service we provide across San Lorenzo’s acreage properties. Our mobile rig handles on-site fabrication of gusseted hinge plates, reinforced operator arms, and modified latch strikes sized to your specific gate weight and geometry — no outsourcing, no delays. Typical custom bracket welding runs $320–$550 depending on steel grade and complexity. Call (510) 616-4869 to schedule Brian for a field measurement and exact quote.
We often can, and when original parts are obsolete, we engineer compatible solutions using our in-house welding capability and knowledge of 9 major brands including LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For San Lorenzo’s concentration of mid-century installations, we’ve developed workarounds for discontinued operator models that other technicians replace unnecessarily. Call (510) 616-4869 with your opener model — we’ll give you an honest assessment of repair vs. replacement.
Because San Lorenzo’s housing stock was built almost entirely as a planned postwar suburb by the Bohannon Development Company starting around 1944, the original redwood and cedar posts were set directly in native soil — standard 1940s–1960s practice with no concrete footing or post-base separation. Decades of soil contact plus San Lorenzo’s marine moisture has turned those posts to spongy punk at the ground line. Replacement with ground-contact-rated lumber on concrete footings with post-base hardware eliminates the problem permanently. Single post replacement runs $280–$480; call (510) 616-4869 for a free estimate.
