Why Sierra Gate Repair San Diego Is San Lorenzo’s Preferred Gate Installation Company
We’ve been driving out to San Lorenzo for gate work long enough to know the difference between a Grant Avenue cottage and a Hesperian Boulevard ranch just by the gate hardware. Frank Delgado, our founder and lead installer, has personally handled installations across unincorporated Alameda County for over 20 years. That means he knows the county permit process inside out, not just the city shortcuts that leave homeowners scrambling later.
Our 375 verified reviews averaging 4.9 stars include plenty from San Lorenzo customers who found us after generalist fence companies couldn’t source parts for their vintage setups. We’re typically on-site in San Lorenzo within 24–48 hours of your call, and we carry parts and welding equipment so we’re not making multiple trips while your old gate sits half-finished.
The difference is specialization. We don’t do decks, fences, or general handyman work. Gates are what we’ve done exclusively for two decades, and that focus shows in how we size operators for tight Bohannon lots, select hardware that survives salt air, and navigate Alameda County Public Works requirements that catch other contractors off guard.
Our Gate Installation Services in San Lorenzo
Swing Gate Installation
Swing gates remain the most common replacement we install in San Lorenzo, largely because the original Bohannon-era homes were designed with inward-swinging wooden gates sized for those standard 6-foot lots. On a tight lot near Grant Avenue, we replaced a pair of original Bohannon-era wooden swing gates, where decades of salt air from the Bay had rusted the steel hinges until they snapped. We retrofitted the opening with a new LiftMaster swing gate operator and galvanized hardware perfectly sized for the 6-foot lot standard in this neighborhood. A new residential swing gate installation in San Lorenzo typically runs $1,800–$3,200 depending on material and operator choice.
Sliding Gate Installation
When driveway depth is limited or the slope makes swinging impractical, a sliding gate can reclaim usable space on your San Lorenzo property. We’ve installed sliding gates on Bohannon lots where the original swing gate arc would have blocked the single-car driveway entirely. Sliding gate installation in San Lorenzo generally costs $2,800–$4,500, with the track and roller system engineered to handle the weight without sagging on those older concrete pads that may have settled over 70 years.
Double Gate Installation
Double gates are the classic replacement for the paired wooden gates that fronted most Bohannon homes. We fabricate steel or aluminum double gate frames in-house, which matters when your opening doesn’t match modern standard sizes. For San Lorenzo’s uniform lot widths, we’ve developed efficient templates that keep double gate installation in the $2,200–$3,800 range while still giving you custom-fit hardware that won’t corrode in the marine layer.
Driveway Gate Installation
Your driveway gate is the main access point, and in San Lorenzo it needs to handle daily use while surviving conditions that inland gates never face. We select materials and operators specifically for Bay-adjacent exposure, not generic inland specs.
Pedestrian Gate Installation
Side-yard pedestrian gates on San Lorenzo’s chain-link fences are often the first to fail from salt-air corrosion. We replace these with welded steel or aluminum frames and hardware rated for marine environments, typically $800–$1,500 installed.
Security Gate Installation
For properties requiring controlled access, we integrate keypad, intercom, or smartphone-operated systems with your new gate. Our Gate Installation team programs DoorKing and Elite access controls on-site, so you’re not waiting for a separate technician.

Trusted Brands We Service in San Lorenzo
We work on virtually every major gate brand, including LiftMaster, DoorKing, and Elite — no referrals, no guesswork. For San Lorenzo installations, we stock operators and replacement parts locally, which means faster turnaround when your vintage system finally gives out. Our 20 years of accumulated parts knowledge and supplier relationships enable us to source components for older systems that generalist competitors simply can’t locate. From a bent frame we can weld on-site to a full smart-access system, it’s all handled in one call.
Common Gate Installation Problems We See in San Lorenzo Homes
- Original 1940s–60s gate hinges and latches on Bohannon homes corrode from salt-laden marine air, leading to sagging or binding that requires full hardware replacement rather than simple adjustment. The fog that lingers in San Lorenzo’s flatland topography keeps metal wet longer than inland cities, accelerating oxidation beyond what standard hardware can survive.
- Vintage one-piece wooden gates have degraded beyond repair after 70+ years of fog and damp; retrofitting with new swing or sliding gates is more cost-effective than patching rot and corrosion repeatedly. We’ve seen homeowners spend more on three rounds of repairs than one proper replacement would have cost.
- Unpermitted gate installations in unincorporated San Lorenzo later require expensive after-the-fact compliance with Alameda County Public Works, especially when replacing legacy openers. Because San Lorenzo is unincorporated Alameda County, permitted gate installations require filing with Alameda County Public Works rather than a city building department — a step many homeowners and even contractors miss, causing delays. We handle this paperwork as part of our standard installation process.
- Chain-link side gates rust through at the bottom rail first, where soil contact and salt air create a perfect corrosion environment. On Bohannon-era homes, these were often the first “upgrade” from original wood, and now they’re failing simultaneously across the neighborhood.
Pricing for Gate Installation in San Lorenzo, CA
Here’s what gate installation costs in San Lorenzo’s current market:
| Service | Typical Range |
| Pedestrian gate (single, manual) | $800 – $1,500 |
| Swing gate (single, with operator) | $1,800 – $3,200 |
| Double swing gate (with operator) | $2,200 – $3,800 |
| Sliding gate (with operator) | $2,800 – $4,500 |
| Access control integration | $400 – $1,200 |
Material choice moves the needle significantly. Steel costs less upfront but requires galvanizing or powder-coating to survive San Lorenzo’s salt air. Aluminum costs 15–25% more but doesn’t rust. Operator selection matters too — a basic Mighty Mule residential unit runs far less than a commercial-grade FAAC or BFT system. Site conditions on older Bohannon properties can add complexity: settled concrete, non-standard post spacing, or buried utilities we’ve encountered near Hesperian Boulevard. We price everything upfront after a site visit. Estimates are free — call (855) 671-2951 to schedule.

Our installation crews work throughout the East Bay corridor, including Ashland, San Leandro, Cherryland, and Castro Valley.

FAQs — Gate Installation in San Lorenzo
Yes, if the replacement involves structural posts, electrical operators, or changes to the opening dimensions. Because San Lorenzo is unincorporated Alameda County, gate installations requiring permits must be filed with Alameda County Public Works, not a city building department. We include permit handling in our standard installation workflow so you don’t face after-the-fact compliance issues. Call (855) 671-2951 and we’ll verify whether your specific project triggers the permit threshold.
San Lorenzo sits only 2–3 miles from the San Francisco Bay shoreline, exposing metal gate components to consistent salt-air moisture that accelerates rust on steel hinges, strikes, and frames well beyond what inland Alameda County communities experience. The low-lying flatland topography also means fog and damp marine layer linger longer in the morning, keeping hardware wet and speeding oxidation. Original Bohannon hardware was never galvanized for marine exposure, so 70–80 years of this environment takes its toll. We specify hot-dip galvanized or stainless hardware for all San Lorenzo replacements.
Usually yes, though it depends on your driveway depth and side-yard clearance. A sliding gate needs roughly the gate’s width in parallel track space, which can work on a 6-foot lot if the driveway runs deep enough. We’ve converted several Grant Avenue-area properties where the original swing gate arc blocked the entire driveway. During your free estimate, we’ll measure your opening and driveway geometry to confirm sliding gate feasibility and give you exact pricing.
LiftMaster residential swing and slide operators are our most frequently installed systems in San Lorenzo, largely due to reliable parts availability and good salt-air durability when properly specified. We also install DoorKing and Elite systems for customers wanting integrated access control. Our familiarity with 9 major brands means we match the operator to your actual usage patterns, not just sell whatever’s in the warehouse.
Replace it. Chain-link gates rusted through at the bottom rail or frame corners can’t be repaired to last — welding new steel to corroded old steel just creates a new galvanic corrosion cell. A new welded steel or aluminum pedestrian gate, properly coated for marine exposure, typically costs $800–$1,500 in San Lorenzo and will outlast any repair by a decade or more. Call (855) 671-2951 for a free estimate — we’ll measure your opening and show you material options.
