You hear a loud bang from the garage. The door now feels impossibly heavy, the opener strains and gives up. The spring overhead has snapped. This is dangerous to attempt yourself. We carry torsion springs in standard wire and length sizes for residential doors.

Typical fix time: 60 to 90 minutes.

The door drops on one side, jams in the track, or hangs at an angle. Cables fray gradually then fail suddenly. If you see fraying, stop using the door. We replace cables in pairs because if one is at end of life, the other is too.

Typical fix time: 45 to 75 minutes.

You press the button. You hear a click or a hum, but no movement. Capacitor failure, burned-out winding, or thermal shutdown after years of overloading. Sometimes it's a $40 capacitor swap. Sometimes the unit is past saving. We tell you which it is before any work starts.

Typical fix time: 30 to 90 minutes.

The motor runs but the door won't move. Plastic drive gear inside the opener has stripped. Common in chain-drive units more than 8 to 10 years old. We carry gear kits for the major brands and can have it rebuilt within an hour.

Typical fix time: 45 to 60 minutes.

A roller fails, the door comes off the rail. Now it's under uneven tension. Do not try to force it back on. Cables can snap and panels can drop. We put it back on track, replace the failed rollers, and inspect every other one before we leave.

Typical fix time: 60 to 120 minutes.

A hinge between panels rusts through or shears off. The door binds, makes loud cracks, or refuses to close flat. Cheap to fix if caught early. We carry the standard 14-gauge hinges and stem rollers.

Typical fix time: 30 to 60 minutes.
