Fast, Reliable Gate Parts & Welding Across San Lorenzo
Gate parts and welding repair in San Lorenzo typically costs $180–$650 depending on whether you’re replacing a hinge, rebuilding a post anchor, or fabricating custom steelwork, and most jobs are completed in a single visit when parts are stocked. We travel to San Lorenzo from our San Francisco base with welding equipment, common hardware, and factory-authorized parts for nine major brands — so your gate isn’t left half-fixed while we order components. If your side-yard gate is dragging, sagging, or rusted through from decades of East Bay moisture, call us at (628) 261-6223 for a free estimate.
We’ve been working on gates in San Lorenzo long enough to know the rhythm of this community. The Bohannon-built San Lorenzo Village tracts — those modest ranch homes on repeated floor plans between Hesperian Boulevard and Via Alamosa — are aging out their original hardware all at once. That means we see the same failures again and again: heaved concrete post anchors from the 1940s and 50s, hinges corroded by marine layer humidity rolling in from the Bay, and side-yard gates wedged into 38-inch clearances that standard equipment can’t access. Our Gate Parts & Welding team carries compact demo hammers, portable welding rigs, and galvanized post hardware specifically for these tight San Lorenzo conditions.
Why Liberty Gate Repair San Francisco Is San Lorenzo’s Preferred Gate Parts & Welding Company
Steven Lee, our owner and lead technician, has spent 31 years working on gates exclusively — not fences, not general construction, just gates. That matters in San Lorenzo Village, where the uniform housing stock demands specialized knowledge of period hardware and confined-space repair techniques. When Steven diagnoses a heaved post on a 1950s side-yard gate, he’s drawing on three decades of similar jobs, not guesswork.
Our reputation is documented: 613 customers rated us 4.9 stars. San Lorenzo homeowners specifically mention our preparedness — arriving with the right compact tools for narrow side yards, not realizing mid-job that standard post-hole diggers won’t fit between a house wall and a property line fence. We’re familiar with your brand, whether it’s a LiftMaster hinge kit on a backyard gate off Grant Avenue or a rusted FAAC drop rod near San Lorenzo Creek.
Response time to San Lorenzo is typically same-day or next-day for standard repairs, and we prioritize emergency calls when a gate is unsecured or blocking vehicle access. We serve all of 94580, from the older Village core near Lewelling Boulevard to the parcels closer to the San Leandro border.
What separates us from out-of-area contractors is local pattern recognition. We’ve replaced enough posts on Via Alamosa, fixed enough marine-layer-rusted latches near the Creek, and squeezed enough welding rigs into 36-inch clearances to know San Lorenzo’s gates before we arrive. Our San Lorenzo customers don’t pay for our learning curve.
Our Gate Parts & Welding Services in San Lorenzo
Post Replacement
Post replacement is our most frequent call in San Lorenzo, and for specific reasons. The original Bohannon-era concrete anchors — poured between 1944 and 1955 — are cracking and heaving across thousands of identical lots. In San Lorenzo Village, we regularly see posts tilted two to four inches as the slab shifts, leaving gates dragging on concrete or binding in their frames. Replacement means extracting the old anchor in a space often narrower than a standard wheelbarrow, then setting a new galvanized post and footing that won’t repeat the same corrosion cycle. We bring compact demo hammers and mini-excavation tools purpose-built for these 36–42 inch clearances. A typical post replacement in San Lorenzo runs $350–$650, including removal, new galvanized steel post, concrete footing, and rehang.
Custom Welding
San Lorenzo’s marine layer keeps steel and wrought iron in perpetual surface moisture, especially on gates facing the Bay or positioned near San Lorenzo Creek where fog lingers. When corrosion has eaten through a rail, weakened a latch mount, or cracked a hinge bracket, we weld repairs on-site rather than removing the gate to a shop. Our portable MIG and stick welding rigs handle steel, wrought iron, and aluminum in your driveway or side yard. For San Lorenzo’s older gates with obsolete hardware, we’ll fabricate custom brackets or reinforce failing joints rather than forcing modern parts onto period frames. Custom welding in San Lorenzo typically ranges from $180–$450 depending on material thickness, access difficulty, and whether we’re repairing a single crack or rebuilding a gate corner.
Hinge Replacement
Hinge failure in San Lorenzo follows a predictable pattern: East Bay humidity attacks the barrel or pin, the gate sags, and homeowners compensate by lifting or dragging until the frame twists. We stock heavy-duty hinges from LiftMaster, Linear, and Viking — plus generic adjustable hinges for gates where the original manufacturer is long gone. On San Lorenzo Village homes, we match hinge throw to the original swing geometry, critical when you’re working with tight clearances and don’t want the gate binding against a house wall or fence post. Hinge replacement in San Lorenzo generally costs $180–$320 for a standard side-yard gate, including hardware and adjustment.
Rail Repair & Gate Rollers
Sliding gates along the Hesperian Boulevard corridor and commercial parcels near Washington Avenue often suffer rail deformation from vehicle impact or decades of wheel wear. We straighten or replace steel track, realign roller carriages, and swap worn V-groove or box-section rollers. For San Lorenzo’s hillside-adjacent properties where driveways slope toward the street, we also inspect roller retention — a gate that jumps track on a grade is a safety issue, not just an inconvenience. Rail and roller work in San Lorenzo runs $220–$480.

Trusted Brands We Service in San Lorenzo
We maintain factory-familiar knowledge across nine major gate brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For San Lorenzo customers, this means we don’t just “work on gates” — we recognize the specific hinge geometry of your Elite swing gate, know the common failure points in FAAC hydraulic operators, and stock LiftMaster hinge kits and Linear actuator brackets for same-day resolution. Our parts inventory travels with us, so a gate off Via Alamosa or near Lewelling Boulevard doesn’t wait on a warehouse shipment. When we say we stock parts and weld on-site, we mean your repair finishes in one visit, not two or three.
Common Gate Parts & Welding Problems We See in San Lorenzo Homes
- Heaved concrete post anchors from the 1940s–50s — The original Bohannon slab construction is simultaneously failing across San Lorenzo Village. Posts tilt, gates sag, and the concrete itself crumbles when we extract the old hardware. We replace with galvanized steel posts set in new footings rated for the clay-heavy East Bay soil.
- Marine layer corrosion on steel hinges and drop rods — San Lorenzo’s lowland position means fog rolls in and stays, keeping hardware damp year-round. Hinge barrels seize, pins rust through, and drop rods on double gates corrode at the ground contact point. We use stainless or galvanized replacements where possible, and weld reinforcements onto frames before they fail completely.
- Tight side-yard clearances defeating standard tools — The uniform 36–42 inch lot setbacks in San Lorenzo Village mean post replacement and welding access is genuinely cramped. Out-of-area contractors often abandon jobs mid-stream when their equipment doesn’t fit. We carry compact demo hammers, mini-breakers, and portable welding rigs specifically for these conditions.
- Gates dragging on original concrete that has settled unevenly — Seventy years of traffic vibration, tree root intrusion, and soil movement have left many San Lorenzo driveways and walkways uneven. A gate that once cleared by an inch now scrapes. We adjust, shim, or replace hinges to compensate; when the frame itself has twisted, we weld corrections on-site.

FAQs — Gate Parts & Welding in San Lorenzo
Your post anchors are likely original to the 1940s–50s Bohannon construction, and the concrete has simply reached end of life. San Lorenzo’s clay-heavy soil expands and contracts with moisture, cracking the slab and tilting the post. We replace with galvanized steel posts set in new footings deep enough to resist future heave. Call (628) 261-6223 and we’ll assess whether the post, the anchor, or both need replacement — estimates are free.
We are factory-familiar with nine major brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. This covers the vast majority of residential and commercial gate systems installed in San Lorenzo over the past three decades. We stock common hardware for same-day repair. If you’re unsure of your brand, Steven can identify it on arrival — call (628) 261-6223 to book.
Yes, in most cases we weld hinge repairs on-site without dismantling the gate. Our portable welding rigs handle steel and wrought iron in position, even in San Lorenzo’s tight side-yard clearances. If the hinge bracket has torn away from the frame, we’ll fabricate a reinforcement plate and weld it in place. Severe corrosion may require full hinge replacement, which we also stock. Call (628) 261-6223 for an exact assessment — estimates are free.
If the gate frame itself is level but the gate sags or binds, it’s likely a hinge issue. If the post leans, the concrete anchor is cracked, or the gate has progressively worsened over years regardless of hinge adjustments, the post has failed. In San Lorenzo Village, we often find both: a heaved post that has stressed the hinges until they too corroded or cracked. Steven diagnoses it, Steven fixes it — call (628) 261-6223 and we’ll determine the right repair before any work begins.
No. Tight clearances are standard conditions for San Lorenzo, not a surcharge situation. We own the compact equipment specifically for these spaces — it’s part of serving this community correctly.
