Fast, Reliable Gate Motor & Opener Across San Lorenzo
Gate motor and opener repair in San Lorenzo typically runs $180-$520 depending on whether the fix is a board replacement, gear rebuild, or full motor swap. Most calls to our Gate Motor & Opener in San Lorenzo route are handled same-day or next-morning, and we stock parts for nine major brands so the job finishes in one visit.
We’ve been driving to San Lorenzo since 1984, long before the 238 interchange was rebuilt. Our technicians know the difference between a gate on Hesperian Boulevard and one tucked behind the Village shops on Lewelling Boulevard. The marine air here is different from inland Hayward, the permitting is different because you’re unincorporated Alameda County, and the gates themselves are different, built in the same decade with the same materials, aging out together. When your opener quits at 6 p.m., you want someone who already knows why. Call (833) 754-7503. A live person answers, 24 hours a day, 7 days a week.
Why Ironworks Gate Co. Is San Lorenzo’s Preferred Gate Motor & Opener Company
San Lorenzo homeowners call us back. They remember the last contractor who diagnosed a $900 motor replacement when the real problem was a $140 limit switch, or who disappeared after collecting a deposit for a “custom order” part that never arrived. We don’t work that way.
Our Gate Motor & Opener team has completed hundreds of jobs in the 94580 ZIP code, from the original San Lorenzo Village ranches to the hillside homes near Bayview Avenue. Victor Salinas personally reviews every motor replacement quote over $600 before it goes out. Our 90-Day Done Right Promise, the Keystone Standard, covers every job in writing. No paperwork to file. No arguing. If it’s not right, we come back and make it right.
We answer the phone live, day or night. Background-checked, uniformed technicians arrive when we say they will. Upfront pricing is settled before a single bolt turns. That’s the square deal.
Our Gate Motor & Opener Services in San Lorenzo
Motor Installation
New motor installation in San Lorenzo runs $850-$2,400 for a typical residential swing or slide gate, including mounting hardware, safety loops, and basic programming. Most San Lorenzo Village homes need more than just the motor: the original gate frame is often warped, the posts are loose in 70-year-old concrete, and the wiring from the house is undersized aluminum that won’t safely power a modern operator. We quote the full job, not just the motor box. Our recent retrofit on Via Alamitos is a good example: a 1950s ranch with a seized FAAC 740 linear motor, estate sale pending, needed a LiftMaster LA500 with battery backup that could handle the gate’s unbalanced spring system. Done in one day. The new owner will never think about it again.
Motor Repair
Not every dead motor needs replacing. A failed capacitor, a corroded contact board, or a stripped worm gear can often be repaired for $180-$340 in San Lorenzo. But we won’t pretend a repair is viable when the parts are obsolete. Legacy FAAC 740 and early LiftMaster CSW200 models are common here, and the gears, boards, and limit switch assemblies are increasingly unavailable. We diagnose honestly. If repair makes sense, we repair. If a $280 repair only buys you eight months before the next failure, we’ll tell you that too, and quote replacement so you can decide.
Linear Motor Service
Linear motors, the long screw-drive or chain-drive units common on swing gates, are a San Lorenzo specialty for us. The FAAC 740 and 741 models were popular in 1950s installations, and we’ve developed workarounds for the most common failures: seized thrust bearings, cracked drive housings, and water intrusion into the motor tube. When repair isn’t practical, we retrofit modern linear operators like the LiftMaster LA500 or Linear SW33 that fit the same mounting footprint without rebuilding the gate. A linear motor replacement in San Lorenzo typically runs $920-$1,600 installed, including safety entrapment devices required by current UL 325 standards.
Slide Motor Repair & Replacement
Slide gates on commercial properties along Mission Boulevard and residential estates near San Lorenzo Creek use rack-and-pinion or chain-driven operators that take a beating. The original concrete channels in older installations often have settled or cracked, binding the gate and overloading the motor. We see this constantly. A slide motor replacement runs $1,100-$2,200 in San Lorenzo, but the real question is whether the gate itself needs retracking or the posts need resetting. We check it all. One visit. One correct diagnosis.
Battery Backup Systems
PG&E’s Public Safety Power Shutoffs and the wind-related outages that roll through the Bay Area hills have made battery backup essential, not optional, for San Lorenzo homeowners. We install LiftMaster and Linear battery backup systems that provide 24-48 hours of standby operation, with automatic charging when power returns. A battery backup add-on runs $340-$520 installed. For new installations, we spec it standard.
Intercom Integration
Upgrading your gate motor is the right time to add or replace an intercom. We wire telephone-entry systems, WiFi-enabled video intercoms, and cellular-based call boxes into new or existing operators. Most San Lorenzo homes have aging two-wire intercom cables that we can reuse or replace, depending on the new system’s requirements. Intercom integration with motor work runs $280-$680.

Trusted Brands We Service in San Lorenzo
We carry parts and factory training for nine gate-automation brands: LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. For San Lorenzo’s high concentration of legacy FAAC and early LiftMaster installations, this matters. An out-of-area contractor sees a dead FAAC 740 and orders a replacement motor that won’t arrive for three weeks. We recognize it, know the failure mode, and either repair it with our stocked parts or quote a same-day retrofit to a current Linear or Viking operator that fits the existing gate. No waiting. No guessing. The right fix on the first visit.
Common Gate Motor & Opener Problems We See in San Lorenzo Homes
- Salt-laden marine air corrodes motor contact boards and limit switches. San Lorenzo sits three to four miles from San Francisco Bay, and the daily marine layer carries enough salt-laden moisture to accelerate failure in non-sealed units. We see intermittent operation or total failure within five years on motors that would last ten in inland Hayward. Corrosion-resistant hardware upgrades are a frequent and worthwhile upsell here.
- Legacy slide gate operators with obsolete rack-and-pinion gears. The original concrete channels on 1950s slide gates often have worn gears that haven’t been manufactured in decades. Repair is impossible. We replace with modern operators that use standard, available gearing.
- Undersized or corroded wiring causing voltage drop and motor burnout. Many San Lorenzo homes still have 14-gauge aluminum wiring from the original opener installation. It can’t handle the startup current of a modern motor. The motor overheats, the thermal cutoff trips repeatedly, and eventually the motor burns out. We replace with proper copper wiring on every installation.
- Gate post shifting from creek-adjacent soil saturation. Homeowners near the San Lorenzo Creek corridor sometimes find their gate posts have heaved or shifted from periodic saturation. The motor labors, the limit switches drift, and the gate eventually jams. Out-of-area companies misdiagnose this as a simple sag adjustment. We recognize the pattern immediately and quote post replacement when that’s the real job.

FAQs - Gate Motor & Opener in San Lorenzo
Sometimes we can repair it, often we cannot. Legacy FAAC 740 and early LiftMaster CSW200 models were built to last, but their parts supply has dried up. If we have the gear, board, or switch in stock, repair runs $180-$340 and you’re back in operation. If the part is obsolete, we quote a retrofit to a modern operator that fits your existing gate. Either way, you’ll know before any work starts. Call (833) 754-7503 and we’ll diagnose it.
Yes, and this trips up homeowners and out-of-area contractors constantly. San Lorenzo is not an incorporated city, so gate and fence permits run through Alameda County Planning & Building, not a city hall. The County has specific requirements for automated gate safety entrapment devices and UL 325 compliance that differ from neighboring San Leandro’s municipal code. We handle the permit research on every installation, pull permits when required, and schedule inspections so you don’t have to navigate County bureaucracy yourself.
Periodic soil saturation from the creek corridor causes gate posts to shift and heave. The gate binds, the motor strains against abnormal load, and the thermal protection eventually fails. The motor isn’t the root problem; the post foundation is. We recognize this pattern immediately and quote post replacement or stabilization when that’s the real fix, not just another motor that will burn out in six months.
We install LiftMaster and Linear battery backup systems rated for 24-48 hours of standby operation with automatic recharge. For San Lorenzo’s exposure to PG&E PSPS events and wind-related outages, we consider battery backup standard equipment, not an option. Add-on cost is $340-$520. On new installations, we include it in the base quote.
Repair if the motor is under ten years old, the part is available, and the gate itself is sound. Replace if the motor is a legacy model with obsolete parts, if you’ve already repaired it once in the past three years, or if the gate frame, hinges, or posts need work anyway. The incremental cost of doing motor and gate together is lower than doing them separately. We’ll give you both numbers and let you decide. Call (833) 754-7503 for a free estimate.
