Why Coastal Gate Repair Service San Jose Is San Lorenzo’s Preferred Gate Repair Company
We’ve built our reputation on single-trade focus—gates and nothing else—and San Lorenzo homeowners notice the difference. Our 661 verified reviews averaging 4.8 stars include repeat calls from residents in the 94580 ZIP who’ve watched generalist contractors struggle with the permit quirks that come with unincorporated Alameda County. Mark Thompson leads every job personally, so the technician quoting your gate realignment on Doxey Avenue is the same person who’ll weld the bracket and set the post footing.
Response time matters when your gate won’t latch and you’re leaving for work. We route San Lorenzo calls directly from our San Jose operation, skipping the dispatch delays that plague franchise outfits. That proximity, combined with in-house parts inventory and welding capability, means we’re not waiting on third-party suppliers for hinge kits or custom brackets.
San Lorenzo’s specific conditions—salt fog off the Bay, shallow DIY footings from decades of homeowner additions, and county-level permitting—aren’t afterthoughts for us. They’re the baseline we plan around.
Our Gate Repair Services in San Lorenzo
Hinge Repair
San Lorenzo’s marine exposure destroys gate hinges faster than almost anywhere in the East Bay. Salt-laden fog rolling through from the southern Bay corrodes pins and bushings on metal hinges within three to five years, even on relatively new installs near the San Lorenzo Creek drainage basin. We replace seized hinges with marine-grade hardware, and when the original mounting plate has rusted through, we weld new steel backing directly to the gate frame. A typical hinge repair in San Lorenzo runs $180–$320.
Post Repair
The Bohannon tract homes built 1944–1950 were never designed with gates in mind. Side-yard posts added by successive owners often sit in shallow holes with minimal or no concrete—six inches of dirt and a prayer, in some cases we’ve found along Carlos Avenue. Winter saturation heaves these footings, and the gate binds, sags, or pulls away entirely. We jackhammer out failed footings and pour new 18-inch deep post bases with proper drainage, which is the only fix that lasts in San Lorenzo’s clay-heavy soils. Post repair with footing replacement typically costs $350–$650.
Weld Repair
Gates take stress at the weld points—especially steel driveway gates with automated openers cycling daily. Our mobile welding rig handles field repairs on cracked frames, broken scrollwork, and separated picket joints without hauling your gate to a shop. For San Lorenzo’s older iron gates, we’ll match existing weld profiles so the repair doesn’t announce itself. Most weld repairs run $200–$400 depending on access and material thickness.
Gate Realignment
A gate that drags, sticks, or won’t latch is usually telling you the post has shifted or the hinges have elongated their bolt holes. In San Lorenzo’s narrow side yards, even a half-inch of post lean can mean the difference between a gate that clears the jamb and one that doesn’t. We diagnose whether the issue is hinge wear, post movement, or frame distortion, then correct it—sometimes with a new hinge set, sometimes with post resetting, sometimes both. Realignment jobs in San Lorenzo typically fall between $220–$450.
Rust Treatment
Surface rust on gates near the Bay side of San Lorenzo accelerates to structural pitting faster than inland customers expect. We grind affected areas to bare metal, treat with rust-converting primer, and finish with enamel matched to your existing color. For wrought iron with recurring corrosion, we’ll recommend drain holes and gap seals that slow the cycle. Rust treatment and coating runs $150–$300 for spot work, $400–$700 for full gate refinishing.

Common Gate Repair Problems We See in San Lorenzo Homes
- Salt-fog corrosion seizes hardware prematurely. Gates less than five years old show frozen hinge pins and pitted latch bolts, especially in the lower-lying western blocks near San Lorenzo Creek where marine fog lingers longest. Regular lubrication helps, but once pitting starts, replacement is the only reliable fix.
- Shallow DIY post footings heave in winter rains. The 1950s–1980s homeowner additions we find throughout the Bohannon tracts frequently lack proper concrete. A season of heavy rain shifts the post, and by spring the gate won’t close squarely.
- Hinge-and-hardware swaps without footing repair fail within a year. Homeowners understandably want the cheapest fix, but new hinges on a leaning post just elongate fresh bolt holes. We see this pattern repeatedly on narrow-lot side gates where the original 3–4 foot clearance makes post access awkward.
- Outward-swing gates violate current Alameda County egress code. In Bohannon tract side yards, replacing an old gate with a code-compliant outward-swing unit often requires relocating the latch-side post entirely—a hidden labor cost that surprises homeowners expecting a simple swap.

FAQs — Gate Repair in San Lorenzo
Yes, if your repair involves structural changes, new posts, or alterations to gate height or location. San Lorenzo is unincorporated Alameda County, so gate and fence permits are handled by the county building department—not San Leandro, not Hayward. Contractors who assume municipal jurisdiction frequently cause delays. We pull county permits regularly and know the setback and wind-load requirements that apply to Bohannon-era lot configurations. Call (833) 848-0143 and we’ll confirm whether your specific job needs permitting.
Marine fog from the southern Bay carries salt that accelerates corrosion on exposed metal. San Lorenzo’s position adjacent to the Bay funnels this moisture through the area year-round, and gates near the San Lorenzo Creek drainage basin see the worst of it. Standard hardware-store hinges without stainless or marine-grade plating simply don’t last here. We specify corrosion-resistant hardware and can install zinc-plated or stainless options that outlast generic replacements by years.
Sometimes, but the 3–4 foot clearances typical of Bohannon side yards often make sliding gates impractical too—you need parallel run space equal to the gate width. We recently replaced a rusted-out slide bolt on a side-yard gate in the 200 block of Doxey Avenue, where the Bohannon-era 3-foot clearance meant we had to jackhammer out a shallow 6-inch footing and pour a new 18-inch deep post base to meet Alameda County wind-load requirements, using a Ghost Controls swing gate opener to handle the 8-foot panel. Mark Thompson can assess your specific dimensions and recommend whether a swing, slide, or bi-fold solution works.
Alameda County requires 18-inch minimum depth for gate posts in wind-exposed applications, with concrete footings extending below the frost line and adequate drainage. The shallow 6–8 inch footings we commonly find in San Lorenzo’s older DIY installs don’t meet this standard and fail repeatedly. When we set a new post, we go to 18–24 inches depending on gate height and exposure, with a gravel drain base to prevent the winter heaving that shifts posts in clay soils.
Yes, regularly. The 1944–1950 Bohannon homes in San Lorenzo have seen successive owners add, modify, and patch gates for 70-plus years, resulting in mismatched hardware, non-standard dimensions, and structural compromises. We work with what exists—repairing original ironwork when salvageable, fabricating custom brackets for odd dimensions, and replacing failed components with modern equivalents that don’t fight the existing structure. Call (833) 848-0143 for a free assessment of your specific gate.
