The fog that defines this city does a number on gate electronics. Salt air off the Pacific eats exposed control boards, limit switches, and keypad contacts faster than anything we see in Oakland or Daly City. That’s why every Calder tech in San Francisco carries sealed enclosures and dielectric grease as standard kit, not as an upsell. You bought a gate that should last. Let’s make it actually do that. Here is what you need to know about getting it fixed right, in a city where “right” means accounting for fog, slope, and old wiring.

Why Calder Gate Repair Is San Francisco’s Preferred Electric Gate Repair Company

Calder Gate Repair is the dedicated gate repair specialist inside the Relay Home Co. family, established in 2009. Each location is independently owned and operated, and the San Francisco Bay Area office runs on one very simple rule: you get a written price before any work begins, a live arrival time you can track, and a 365-Day Done Right Promise in writing on every single job. The invoice you get at the end matches the number you agreed to at the door. Never a surprise.

San Francisco homeowners call us because we understand what this city does to gate equipment. Fog-belt corrosion, hillside hinge posts tilting out of their footings, underground loop detector wires chewed by raccoons in dense backyards. These are the calls we run every week in Glen Park, Noe Valley, the Richmond, and over in Portola. Our techs are background-checked, in uniform, and factory-familiar with nine major opener brands. When a LiftMaster board fries from salt exposure on a west-facing driveway off Geary, we know what we’re looking at before we unbolt the cover. That’s why we show up with the right parts the first time.

Every Calder technician is dispatched through The Relay Standard: a live, trackable arrival window sent to your phone. No “sometime between 8 and noon.” You’ll see exactly when we’re pulling up. We take before-and-after photos, we walk you through the safety test before we leave, and you get a digital invoice you can pay from a link. Trust is built on documentation, not promises. Our San Francisco customers keep the paperwork because it proves the work was done correctly.

Electric Gate Motor in San Francisco

Electric gate motor repair in San Francisco is what we do most, and the reasons are specific to this city: fog corrosion on west-side properties, the torque load from swing gates on sloped lots, and wiring that was run decades ago without sealed conduit. Most gate opener motor repairs in San Francisco run $225 to $475, with full motor replacements running $850 to $2,800 depending on brand and load capacity. We diagnose the motor, the limit switch, and the control board before recommending a fix, and you’ll have a written number before any work starts.

What a Real Motor Repair Includes

A proper motor repair means more than replacing the board. It means cleaning and re-seating the limit switch, checking the load against the motor’s rated capacity, inspecting the harness for corrosion or heat damage, and then running a full cycle test. On a San Francisco hillside, we also check the hinge post and the gate’s sag. A motor set up on a sagging leaf to fail again in months. That’s why our repair report includes notes on the whole system, not just the part that failed.

When to Repair vs. Replace

If your motor hums but won’t move the gate, that’s usually the capacitor or the drive belt. $180 to $320 and an hour to fix. If the motor is 12-plus years old and the board is original, a replacement often makes more financial sense. We’ll show you both numbers and explain which path gets you the most years per dollar. You decide, with a written quote for each option.

Gate Access Control in San Francisco

Gate access control in San Francisco comes up constantly with multi-unit buildings, shared driveways, and HOA-managed properties where more than one household needs reliable entry. A full access control installation, meaning a new keypad, intercom, or GSM-based phone entry system wired into the operator, typically runs $800 to $1,700 in San Francisco. Repairing an existing keypad or re-programming entry codes is simpler work, usually $150 to $330. Either way, the price is in writing before we touch a wire.

Multi-Tenant and HOA Access Needs

San Francisco’s housing density means we regularly set up gate access control for buildings with three or more units. We program unique entry codes for each unit, set time restrictions where needed, and leave you a written code log so a departing tenant can’t keep reusing a code. For HOA-governed properties, we provide a documented service record and a written summary of what was installed and tested. That paperwork makes board approvals and future maintenance conversations a lot easier.

Integration With Existing Openers

Most San Francisco homes already have an opener, and the access control can usually be retrofit. We’re factory-familiar with LiftMaster, FAAC, BFT, and Linear, among others, and we know what each board’s accessory ports support. We’ll wire the new keypad or phone entry into the existing operator, test the relay logic, and run a full open-close cycle with each credential. No bloat, no unnecessary replacement.

Trusted Brands We Service in San Francisco

We service, repair, and install across nine major gate opener brands, and the ones we see most in San Francisco are LiftMaster, FAAC, and Linear, especially on the west side where older systems are doing battle with fog salt. Our local parts inventory in the Bay Area covers common FAAC and BFT limit switch assemblies, Linear control boards, and LiftMaster drive belts. That means shorter turnaround on common repairs. When a part is uncommon, we source it direct and keep you updated. You won’t be left calling us for status. We text you when it lands.

Common Electric Gate Repair Problems We See in San Francisco Homes

• Fog-belt corrosion: West-side properties in the Sunset, Richmond, and Parkside absorb Pacific salt air daily. Exposed control boards, limit switches, and keypad contacts corrode and short out. We seal enclosures and use dielectric grease on every connection we touch.
• Hillside hinge-post rot and footing failure: Constant lateral load on a swing gate in steep neighborhoods torques the hinge post out of its concrete footing over time. Replacing or welding the panel alone solves nothing. We inspect the post, the footing, and the gate’s total weight before recommending a fix.
• Chewed or buried loop detector wiring: Raccoons and gophers live dense in the backyard corridors of neighborhoods like Noe Valley and Glen Park. When the inductive loop wire is severed, a slide gate gets stuck open or cycles erratically. We excavate, re-splice the loop in sealed conduit, and verify the detection field.
• Dead keypads from water intrusion: San Francisco’s winter rains, especially on west-facing gates, get past worn keypad seals and fry the contacts. We replace the gaskets and weather-seal the housing when we install the new keypad, not strictly as an upsell.
