Fast, Reliable Gate Repair Across San Lorenzo
Gate repair in San Lorenzo usually means one of two things: a swing gate that’s dragging on the driveway, or a slide gate that’s binding on its track and tripping the operator. We handle both, plus the underlying problems that cause them. Most repairs here come down to the same root issue: the bay-clay soil under San Lorenzo moves, the hinge posts move with it, and the gate panel follows. Call (469) 530-2485 and a live person answers. We’ll send a background-checked, uniformed technician to your San Lorenzo address with a written price before any work starts.
Why Carver Gate Repair Is San Lorenzo’s Preferred Gate Repair Company
San Lorenzo homeowners have dealt with enough no-shows and moving prices. We work to a different standard: The Garrison Standard, in place since 2008 across the Garrison Partners family. Every repair gets a written price before work begins. Every repair carries a written 365-Day Done Right Promise. If the repair fails inside that year, we come back and fix it free. No charge, no argument.
Our technicians arrive in uniform, background-checked, and trained on nine gate-motor brands including LiftMaster, FAAC, BFT, Linear, Viking, Ghost Controls, DoorKing, Elite, and Mighty Mule. When you call, a live person picks up, 24/7. Not a voicemail box. Not a call-back queue. That matters when your gate won’t close at 9pm in San Lorenzo.
Lonnie Burke leads the team, and the standard is simple: show up when we say we will, quote a price that doesn’t move, and leave the site clean. That’s how we’ve built our reputation across San Lorenzo, San Leandro, and the surrounding Alameda County neighborhoods.
Iron Gate Repair in San Lorenzo
Iron gate repair in San Lorenzo is rarely about the iron itself. The panels are usually square and true. The problem is almost always the hinge post underneath. San Lorenzo sits on bay-clay that expands in wet winters and shrinks in dry summers. Posts set in that soil heave and settle seasonally, which tips the gate panel and makes it drag. That’s the actual repair: setting the post correctly, not replacing the gate.
Typical iron gate repair in San Lorenzo runs $280 – $520 depending on the post condition and how far it’s moved. If the post footing has failed completely, expect to add $200 – $350 for excavation and a proper concrete pour. If the operator is straining against a sagging panel, the motor service runs $180 – $340 on top of the structural work.
Post Reset and Realignment
We dig out the old footing, reset the post plumb, and pour a new base with proper drainage. Then we rehang the panel and adjust the hinges so the gate swings clean in both directions.
Weld and Rust Repair
Wrought-iron gates near the bay pick up rust at the bottom rail and hinge welds from moisture and fog. We grind back the rust, weld any cracked joints, and re-coat the affected steel before it spreads. A typical weld repair runs $180 – $360 per affected section.
Sliding Gate Repair in San Lorenzo
Sliding gate repair in San Lorenzo is usually a track problem, not a motor problem. Most San Lorenzo driveways were graded flat, not sloped for slide gates. Water pools at the track, dirt packs into the roller channel, and the trolley binds. The operator overloads and trips on every open cycle. The repair means cleaning and regrading the track, replacing flat rollers, and re-leveling the chain or rack so the motor isn’t fighting the gate.
Sliding gate track and roller work in San Lorenzo typically runs $260 – $480. If the operator has been tripping for months, the motor itself may need rebuilt or replaced; a slide gate operator replacement runs $550 – $1,150 depending on brand and horsepower. We work on Viking, Linear, and BFT slide operators, among others.
Track Cleaning and Roller Replacement
We pull the gate off its track, clear the caked bay-clay sediment, replace the rollers, and set the track level. Then we cycle the gate manually ten times before touching the operator.
Operator Diagnostics on Slide Gates
If the motor trips the moment it engages, the limit switch or the current-sense circuit is usually misadjusted for the load. We tune the limit switch to the actual travel distance and verify the safety edges are wired correctly. A limit switch repair runs $140 – $220 in San Lorenzo.
Trusted Brands We Service in San Lorenzo
We service FAAC, BFT, Linear, and Viking operators throughout San Lorenzo. Most homes here run a mix: older LiftMaster slide operators on San Lorenzo Village driveways, FAAC and BFT swing operators on newer installations, Viking and Linear on commercial or larger residential gates. Our trucks carry common parts for these systems, so we can often complete a motor repair in one visit rather than ordering a board and coming back a week later. If your operator is a brand we haven’t named, ask. We’re trained on nine major gate-motor systems.
Common Gate Repair Problems We See in San Lorenzo Homes
- Hinge post heave: Bay-clay soil swells in wet winters and shrinks in summer, tipping the post and sagging the gate panel. The gate looks broken; the post actually moved.
- Track bind on flat driveways: Slide gates on San Lorenzo’s flat mid-century driveways collect water and sediment in the track, which overloads the operator and trips it every cycle.
- Old gates with new openers, no safety edges: Homeowners retrofit an automatic opener onto a 1960s chain-link or wrought-iron gate but skip the safety photocells and reversing edges. That’s a UL 325 violation and a real hazard if a kid or pet runs through while the gate is closing.
- Control boards corroding from bay fog: Gates mounted near grade in San Lorenzo sit in the fog line at night. Moisture gets into the control board enclosure, and the board fails from corrosion rather than electrical overload.

FAQs About Gate Repair in San Lorenzo
The hinge post has moved. San Lorenzo’s bay-clay soil expands and contracts with the seasons, which tips posts set without a deep enough footing. The panel itself is usually fine; the post underneath it needs resetting and re-plumbing. In San Lorenzo, a post reset typically runs $280 – $520.
Yes. Any automatic gate serviced in San Lorenzo must have working safety photocells and a functional reversing edge, and we test both before we leave. It’s not optional. It’s a UL 325 safety requirement, and we won’t leave an operator running without them. The testing is always part of our repair.
We service FAAC, BFT, Linear, Viking, LiftMaster, Ghost Controls, DoorKing, Elite, and Mighty Mule operators. If your San Lorenzo gate runs one of those brands, we likely have the parts on the truck or can get them same-week.
In most cases, yes. A solar conversion works well here because San Lorenzo gets consistent sun on the driveway side of most homes. The conversion includes the panel, charge controller, battery box, and wiring to the operator. A solar conversion typically runs $900 – $1,800. Call (469) 530-2485 and we’ll tell you if your gate is a good candidate.
A repair like a post reset, track cleaning, or limit switch adjustment usually takes 2 – 4 hours on site. A full gate installation, with new posts, grounding, power run, operator, safety edges, and testing, typically takes one to two days. We always quote a written timeframe with the price. Estimates are free.
