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.

Why Granite Gate Repair California Is San Lorenzo’s Preferred Gate Repair Company
We’ve earned 197 verified reviews with a 4.7-star average by showing up prepared and diagnosing gates correctly the first time. San Lorenzo homeowners tell us they appreciate that Louis Barrera still works in the field — he’s not an absentee owner dispatching subcontractors who’ve never seen a 1940s gate post.
Our response time to San Lorenzo averages under an hour because we know the route down I-880 and the local street grid. We understand the specific failure patterns here: the marine-layer corrosion, the clay-soil post rot, the synchronized aging of hardware installed during David Bohannon’s original construction wave. That local knowledge saves you money. We don’t sell you a full gate replacement when a welded hinge repair and proper post footing will get you another decade.
We weld, source, and repair in-house. No waiting on outside fabricators. No markup on parts we don’t stock.
Our Gate Repair Services in San Lorenzo
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.
Weld Repair
When a rusted hinge tears out of a steel frame or a decorative element snaps, most gate companies in San Lorenzo have to haul the piece to an outside welder and make you wait. We don’t. Louis brings portable welding equipment to the job. On a recent repair near Hesperian Boulevard, we welded a cracked steel frame and fabricated a custom hinge bracket to match the narrow post spacing of the original 1948 installation. Weld repairs generally run $220–$380 depending on material thickness and access.
Hinge Repair & Replacement
Galvanized steel hinges from the 1940s and 1950s don’t last forever in San Lorenzo’s wet microclimate. We’ve replaced hinges that have rusted through to paper-thin remnants, and we’ve sourced modern stainless or powder-coated replacements that fit the original narrow post spacing. Your brand, our specialty — whether it’s a manual gate or automated with a Linear or Viking operator. Hinge repair or replacement in San Lorenzo: $150–$280.
Rust Treatment
San Lorenzo’s morning marine layer and higher humidity than inland Hayward accelerate corrosion on every metal surface. We grind affected areas, apply rust converter, and finish with primer and paint matched to your gate. For severely compromised steel, we cut out the damaged section and weld in fresh material. Rust treatment ranges from $180 for surface work to $400+ for structural restoration.
Lock Repair
Original gate locks on San Lorenzo homes are often seized from decades of corrosion or have keyways worn to the point of accepting any similar key. We repair what we can and replace with modern weather-resistant hardware when necessary, always respecting the narrow stile dimensions common to 1940s gates. Lock repair: $140–$260.

Common Gate Repair Problems We See in San Lorenzo Homes
- Synchronized post rot across entire blocks. Because San Lorenzo was built as a single planned community in 1944–1952, neighbors on the same street often call us within months of each other with identical post failures. The original wood was set in clay without concrete, and 75 years of San Lorenzo’s wet microclimate has done its work.
- Galvanized hardware rusting through prematurely. That marine layer rolling in from the bay every morning keeps humidity elevated. Hinges and latches that might last 30 years in Livermore fail in 15 here. We replace with stainless or properly coated hardware.
- Seasonal re-racking after winter rains. Properties near San Lorenzo Creek or the flood-control channel see gates drop out of plumb every wet season as clay soil expands and contracts. Fixing the hardware without addressing the leaning post is a guaranteed callback by March.
- Obsolete opener parts on original installations. The 1950s gate automation was rare, but where it exists, finding compatible parts is a challenge. Our nine-brand fluency and parts sourcing network usually solves what general handymen can’t.

San Lorenzo’s Unique Gate Challenge: The Planned-Community Aging Wave
San Lorenzo was developed almost entirely as David Bohannon’s large-scale post-WWII planned community in the late 1940s. The residential housing stock is unusually uniform in age — the original wood and chain-link gates and fence hardware installed during that single construction wave are now 70–75 years old and failing at scale across the neighborhood simultaneously. Gate repair here is less about one-off fixes and more about addressing a community-wide cohort of aging, same-era installations.
On a ranch home near the corner of Via Alamitos and Hesperian Boulevard, we replaced four rusted-out galvanized hinges and a seized Linear opener on a one-piece wooden gate. The original posts, set directly in clay soil with no concrete footing, had rotted six inches below grade, requiring full post replacement and concrete boots to prevent future racking.
This history matters for your repair strategy. If your gate is original to a 1948–1952 Bohannon home, the hardware spacing, post dimensions, and fence height don’t match modern standards. Replacement hardware must accommodate narrow post spacings and low fence heights typical of these 1940s lot layouts. We carry adapters and can fabricate custom brackets when needed. We also know when to recommend retrofit versus full replacement — sometimes a new steel frame on your existing posts, properly footed, gives you 20 years at half the cost of starting over.

FAQs — Gate Repair in San Lorenzo
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 post assessment.
Yes, this is extremely common in San Lorenzo, especially for properties near the creek or flood-control channel where clay soil expands when saturated and shrinks back in summer, throwing gates out of square every wet season. We fix the immediate alignment and check whether your posts are leaning — addressing only the hardware without stabilizing the post guarantees the problem returns. Gate realignment in San Lorenzo typically costs $180–$320.
Sometimes we can source NOS (new old stock) or cross-reference modern equivalents for vintage openers, though availability varies by brand and model. Our nine-brand fluency — including Linear, Viking, and FAAC — means we know which discontinued parts have direct substitutes and which situations require a motor upgrade. We’ll give you an honest assessment: repair if it makes sense, replace if it doesn’t. Estimates are free — call (888) 416-1369.
Repair is usually the better value if the frame is structurally sound and the issue is localized hardware, post rot, or surface rust. Full replacement makes sense when the frame itself is compromised, the gate has been re-repaired multiple times, or you want to upgrade to automation that requires a sturdier structure. For San Lorenzo’s 1940s gates, we often recommend a middle path: retain the original design and dimensions but retrofit with a reinforced steel frame and modern hardware. We’ll walk you through both options with real numbers.
Modern standard hardware often won’t fit the narrow post spacings and low fence heights of Bohannon-era 1940s lot layouts, but we carry adapters and can fabricate custom brackets in-house to bridge the gap. On a recent job near Hesperian Boulevard, we welded a custom hinge bracket to match original spacing without modifying the posts. Louis and the Granite Gate team solve fit problems that general handymen walk away from.
