Automatic gate repair is the diagnosis and repair of the powered parts of a gate, the operator or motor, the control board, the safety sensors, and the access controls, along with the mechanical parts like hinges, rollers, track, and welds that let the gate move. The goal is a gate that opens, closes, and reverses safely on its own.
San Rafael gates work harder than most. Hillside driveways in Sun Valley and Gerstle Park pull posts and hinges out of line as grades settle, wooded streets drop leaves and debris into tracks and photo eyes, and homes near the water in Peacock Gap and Loch Lomond deal with damp salt air on every moving part. We repair every part of a residential or commercial gate: gate openers, control boards, safety sensors, and the metalwork itself. For a recent example of our work in town, see our San Rafael custom cedar gate project.

Gate problems we fix in San Rafael
If your gate is doing any of these, it is a repair we handle every week.
Gate will not open or close
Dead power, a tripped safety sensor, a failed board, or a worn motor. We find the real cause and get you moving again.
Sagging or out of alignment
Hillside lots settle and posts move. We rehang leaves, adjust hinges, and realign gates that bind, drag, or no longer meet in the middle.
Opener or motor failure
A hydraulic, chain, or screw-drive operator that hums, stalls, or is dead. We repair or replace it with the right unit.
Rust and worn hardware
Damp salt air near the bay corrodes hinges, chains, and fasteners. We replace worn hardware and protect what remains.
