Why San Lorenzo Residents Choose Us for Linear Service
We’ve been fixing Linear operators in San Lorenzo long enough to know that a “motor failure” on an LSO swing gate is often just corrosion at the terminal block—oxidized wiring that mimics a dead motor until you know to look for it. That’s the difference between a specialist who stocks dielectric grease and spare terminal assemblies, and a general contractor who orders a $400 motor they don’t need.
Kevin Lewis grew up near Midtown and cut his teeth on gate electrical systems at Foothill College in Los Altos Hills before spending 16 years building this company into a gate-only practice. He’s the one who shows up. Not a subcontractor. Not a dispatcher sending someone else’s crew. When you call about your Linear gate in San Lorenzo, Kevin and our team bring 542 verified reviews worth of pattern recognition to your driveway—plus parts inventory for nine brands, Linear included, that most local competitors simply don’t carry.
We’re independent. Not manufacturer-authorized. That means we fix what Linear’s warranty network often won’t touch: obsolescent LCO models from the 1990s, salt-damaged boards that “test fine” on the bench but fail in San Lorenzo’s humidity, and gates held together by optimism long past their service life. We source OEM Linear boards and motors for direct replacements, but we also upgrade hardware to marine-grade 316 stainless steel that outlasts the original plating in this environment.
Common Linear Gate Repair Problems We Solve in San Lorenzo
- Rust-through of LCO limit-switch contacts. San Lorenzo’s salt fog drifting up from the Bay and San Lorenzo Creek corrodes the micro-switch contacts inside Linear LCO operators even when the main board reads normal voltage. The gate reverses intermittently, confuses homeowners, and gets misdiagnosed as a logic board issue. We clean, re-grease, and stainless-cover these—repair, not replace, if the operator’s under ten years old.
- Terminal block corrosion on LSO swing operators. The LSO’s wiring terminal block sits low on the operator housing, right where marine moisture collects. Oxidized connections drop voltage to the motor, producing the exact symptoms of motor failure: slow operation, thermal cutoff, refusal to start. We’ve replaced enough terminal blocks on Bohannon tract homes to keep them in stock.
- Galvanic corrosion at operator brackets. Linear’s powder-coated steel brackets meet galvanized gate posts, and in San Lorenzo’s persistent humidity—especially where shallow Bohannon-era footings trap groundwater—the galvanic reaction eats the bracket from underneath. The powder coat looks fine until the bracket cracks under load. We fabricate replacement brackets in-house and weld them with 316 stainless hardware that survives this climate.
- Remote receiver antenna degradation. Linear’s receiver antenna connectors corrode in San Lorenzo’s high-ambient-moisture environment, cutting remote range to under ten feet. Homeowners think it’s the remote battery. It’s not. We replace the antenna assembly with a sealed upgrade and relocate the receiver housing when possible.
- Hinge seizure from rust-jacking. The original wrought-iron and steel gates on 1947–1955 Bohannon tract homes weren’t designed for automatic operators. When Linear motors get installed on these aging gates, the rusted hinges bind, the motor strains, and the limit switches take a beating. We separate hinge repair from operator diagnosis—fix the mechanical problem first, then calibrate the Linear drive to actual gate resistance.
Linear Service in San Lorenzo: What Local Conditions Mean for Your Equipment
San Lorenzo’s Bohannon tract homes—built 1947–1955—have nearly identical fence setbacks and post-footing depths block after block, so a leaning gate post here almost always traces back to the same shallow mid-century concrete footings. An experienced local pro can diagnose that root cause before even touching the gate—a pattern unique to this planned community.
Here’s what that means if you own a Linear operator in San Lorenzo. That “gate won’t close evenly” complaint? On Via Alamitos, on Via Del Sol, on virtually any Bohannon street, we check post plumb before we check limit switches. The shallow footings settle differentially as groundwater fluctuates along San Lorenzo Creek, tilting the gate frame and throwing off the Linear operator’s geometry. The limit switches hunt for positions that no longer exist. The motor runs longer, hotter, and eventually fails—not because the operator’s bad, but because the gate it’s driving is out of square.
We fixed exactly this on Via Alamitos—a 1998 Linear LCO swing gate whose limit-switch contacts had rusted through from salt fog drifting up the creek. Instead of replacing the entire board, we cleaned the contacts with dielectric grease and replaced the stainless steel switch cover. The gate opened cleanly again, and we advised the owner to expect the same issue on the neighbor’s identical gate in about 18 months. That’s the kind of pattern recognition you get from 16 years in this specific zip code, not from a handyman who touched one Linear unit three years ago.
Linear Models & Products We Service in San Lorenzo
We stock and service the full Linear residential and light-commercial line: LCO swing-gate operators (the workhorse of 1990s–2010s installations), LSO medium-duty swing operators, LDO slide-gate drives, and the Mighty Mule shared-platform units that Linear manufactured for the retail market. Our parts inventory covers boards, motors, limit-switch assemblies, gearboxes, and remote receivers for these model families.
For San Lorenzo’s salt-air conditions, we don’t default to aftermarket replacement boards. OEM Linear control boards carry conformal coating that aftermarket alternatives often skip—critical when your operator lives 800 yards from a tidal creek. For brackets, hinges, and hardware, we actually upgrade: 316 marine stainless outlasts Linear’s standard zinc plating in this environment. We repair before replacing on any operator under ten years old. If the motor’s truly burned out or the gearbox is cracked, we’ll tell you exactly why and show you the failure mode.

What drives cost? Accessibility of the operator, whether we’re matching existing 1950s gate geometry to modern Linear hardware, and how far the salt corrosion has traveled into wiring and brackets. Our diagnostic fee—credited toward repair—covers a full electrical and mechanical assessment. We don’t quote over the phone for problems we haven’t seen. Call (831) 218-8355 to schedule; estimates are free and Kevin handles the inspection personally.

FAQs — Linear Gate Repair in San Lorenzo
Probably not. In San Lorenzo, this symptom usually traces to rusted LCO limit-switch contacts or terminal block corrosion that drops voltage under load. The motor receives partial power, turns briefly, then stalls. We test actual amp draw against Linear’s spec before condemning any motor. Call (831) 218-8355 and we’ll diagnose it same-day—motor replacement is a last resort, not a first guess.
Temperature and humidity swings. San Lorenzo’s marine fog raises ambient moisture during morning and evening hours, corroding the receiver antenna connector and reducing effective range. At night, drier air temporarily improves the weak connection. We replace the antenna assembly with a sealed connector and often relocate the receiver housing above the moisture line. Call (831) 218-8355 for a range test—it’s a quick fix once properly identified.
Almost certainly not. In San Lorenzo’s Bohannon tracts, leaning posts follow a single pattern: shallow 1940s–50s footings deteriorating in creek-zone moisture. The Linear operator is probably fine; it’s fighting a gate frame that’s out of square. We diagnose post plumb first, reset or replace the footing, then realign the gate to the existing operator. Replacing a good Linear drive because of a footing problem is money thrown away.
No. Bracket corrosion is local and repairable. We fabricate replacement brackets in-house, weld with 316 stainless hardware, and powder-coat to match. The operator itself—board, motor, gearbox—often has years of life left. We only replace the full unit when multiple major components have failed or the unit exceeds ten years with recurring issues. Call (831) 218-8355 for a bracket inspection; we’ll show you exactly what’s rusted and what’s solid.
Yes, with structural prep. Original Bohannon tract gates weren’t built for automatic operators—the hinges, posts, and frames need assessment before any Linear drive goes on. We reinforce or replace rusted hinges, reset leaning posts, and sometimes fabricate custom mounting geometry to match the original gate without destroying its character. The operator installation is straightforward; making the gate worthy of it is where our welding capability matters.
