Our Gate Parts & Welding Services in San Lorenzo
Hinge Replacement
Seized galvanized hinges are the single most common gate parts call we get in San Lorenzo. The original postwar hardware—installed when David D. Bohannon built these tracts between 1944 and 1955—has simply exceeded its service life. Bay-influenced morning fog and creek-corridor moisture finish what decades of use started. We extract the legacy hinges from deteriorating concrete or wood, install modern sealed-bearing or heavy-duty strap hinges rated for San Lorenzo’s humidity, and align the gate to proper swing geometry. Typical hinge replacement in San Lorenzo runs $180–$320.
Post Replacement
Here’s the reality of San Lorenzo gate work: because nearly all homes in San Lorenzo were built between 1944 and 1955 by one developer, the side-yard gate openings are uniformly 4 feet wide with original concrete footings from the 1940s—meaning every hinge replacement requires careful extraction of legacy hardware from aged, crumbling concrete. When the redwood post itself has rotted at grade, we remove the old footing, pour new concrete with proper drainage slope away from San Lorenzo’s moisture-retentive clay soils, and set a pressure-treated or steel post with modern bracketry. Post replacement in San Lorenzo typically costs $350–$650 depending on whether we’re matching existing fence lines or upgrading to a heavier gate load.
Rail Repair
Sagging one-piece wood gates plague San Lorenzo homes where original frames were never engineered for modern electric openers. The added weight and cycling stress warp rails over time. We assess whether the frame can be salvaged with internal steel bracing or whether section replacement makes more sense. For gates near San Lorenzo Creek where moisture has compromised multiple joints, rail repair often pairs with custom welding to add rigid support without rebuilding the entire gate. Rail repair work in San Lorenzo generally falls between $280–$480.
Custom Welding
Our in-house welding separates us from every generalist handyman in the East Bay. When your gate frame has cracked at a stress point, when a modern opener needs a bracket that doesn’t exist for your 1940s wood gate, or when rust has eaten through a steel rail near the creek corridor, we fabricate and weld on-site. We recently replaced a set of seized original galvanized hinges and a rusted drop rod on a 1949 home near San Lorenzo Creek on Via Alamitos. The homeowner’s original LiftMaster opener from the 1980s had finally given out, so we retrofitted a modern Ghost Controls operator after welding a new bracket to the existing one-piece wood gate frame. Custom welding and bracket fabrication in San Lorenzo starts around $250–$450 for most residential jobs.

Common Gate Parts & Welding Problems We See in San Lorenzo Homes
- Seized galvanized hinges and latches from the original 1940s hardware, accelerated by moisture from San Lorenzo Creek. The creek corridor creates a microclimate of higher ambient moisture than Castro Valley or Fairview see, and that dampness penetrates the zinc coating on vintage hinges until they freeze solid. We cut them out and upgrade to modern sealed hardware.
- Rotted redwood posts set in deteriorating 1940s-era concrete footings, requiring post replacement with new concrete and brackets. The original footings were poured with minimal rebar and no moisture barrier against San Lorenzo’s clay soil. After 75+ years, the concrete spalls and the post base absorbs groundwater. We excavate, pour new footings with proper depth, and set galvanized or stainless brackets.
- Sagging one-piece wood gates due to warped frames that were never designed for modern electric openers, leading to rail repair or custom bracing. Homeowners add openers to original gates without reinforcing the frame, and the cumulative load pulls the gate out of square. We weld internal steel bracing or replace compromised rails to handle the motorized cycle count.
- Accelerated hardware corrosion on creek-adjacent properties compared to drier East Bay locations. Homes within three blocks of San Lorenzo Creek see hinge and latch rust rates we’d expect in significantly wetter climates. We specify marine-grade or hot-dip galvanized replacements for these locations.

FAQs — Gate Parts & Welding in San Lorenzo
David D. Bohannon developed nearly all of San Lorenzo as a single planned community between 1944 and 1955, and every side-yard gate opening was standardized to 4 feet across the tracts. Those original posts and concrete footings are now 70+ years old, and the combination of moisture from San Lorenzo Creek and clay soil expansion has rotted or undermined most of them. We replace posts in San Lorenzo several times per month, and the uniform dimensions actually make our work more efficient. Call (833) 614-4219 for a free post assessment.
You can keep it if it’s still running safely, but we rarely recommend it. Those vintage LiftMaster units lack modern safety entrapment sensors, draw excessive current for their output, and parts availability has dried up. We typically retrofit a current Ghost Controls or Linear operator with a custom-welded mounting bracket to your existing frame, giving you modern safety features without rebuilding the gate. We’ll honestly assess your old unit’s condition when we’re on-site. Call (833) 614-4219 to discuss retrofit options.
Yes, and that’s often the right fix. Creek-adjacent homes in San Lorenzo see hinge corrosion 3–5 years faster than properties further inland. We cut out the seized originals, extract the remaining bolts from deteriorated concrete or wood, and install sealed-bearing or heavy-duty strap hinges rated for high-moisture environments. If the post itself is compromised, we’ll tell you before we start. Hinge replacement near San Lorenzo Creek typically runs $220–$320 due to corrosion severity. Call (833) 614-4219 for an exact quote.
We stock FAAC control boards, hydraulic fluid seals, and limit switch assemblies for the older FAAC 400 and 422 series still running at some San Lorenzo apartment complexes and HOAs. If your FAAC system needs a part we don’t have on the truck, our supplier relationship gets it within 24–48 hours. We work on FAAC regularly enough that Joseph carries common failure components as standard inventory. Call (833) 614-4219 with your model number and we’ll confirm parts availability.
Hinge adjustment helps if the gate is merely out of alignment, but San Lorenzo’s sagging gates usually have frame deformation that adjustment can’t fix. The original one-piece wood frames weren’t built to handle modern opener stress, and the wood itself has warped after decades of creek-corridor moisture cycling. We weld internal steel bracing or external angle-iron reinforcement to restore square geometry without replacing the entire gate. Joseph will show you the frame deflection when he arrives and explain whether welding or simpler adjustment is the honest fix. Call (833) 614-4219 for a free evaluation.

Whether you’re dealing with seized 1940s hinges on Via Alamitos, a rotted post near the creek corridor, or a sagging frame that needs custom welding, Joseph handles the job himself. 11 years, one specialty.
