Identify what your door is doing before you call. If it is one of these, do not keep operating it.
Your torsion spring has snapped under intense torsional load. Forcing the opener to lift the door without spring assistance will burn out the motor or snap the drive belt.
A lift cable has slipped off the drum or a roller bearing has seized and popped out. Operating the door in this state can completely drop the heavy panels.
A stripped internal nylon drive gear or a blown starting capacitor. We carry complete carriage gear rebuild kits in our trucks to repair your system immediately.
Don't let a snapped spring, snapped cable, ripped weather seal, or a defective remote keep you locked inside. Our expert teams carry fully stocked dispatch trucks. We regularly perform comprehensive garage door maintenance (inspection, lubrication, adjustment, and component testing) to keep your system safe. We serve San Mateo and the cities around it.
A cable rarely wears out evenly. It parts where something bent it.
Take the two ends of a lift cable: the loop that dead-ends at the bottom of the door, and the inner wrap where the load comes onto the drum. Strands break at those two points first, the wire unlays, and a broken one stands out far enough to catch a rag. What sets it off is one event on one side: a kink from the door landing on something, a strand nicked and left to rust. Then the door hangs from one point — the good cable lifts, the dead corner stays down, and the top of the door twists into its track. Unloaded, the freed cable lifts out of its grooves and spools off behind the drum, scoring it. Half of San Mateo's homes were finished before 1964, so that pair can be original — and a pair is how it goes back.
