Garage Door Cable Repair in Lemon Grove, CA

Of Lemon Grove's 9,391 homes, 36.6% were built in the 1940s or 1950s (U.S. Census Bureau, ACS 5-year estimates covering 2020 to 2024). Houses that age have nearly always had their garage door swapped, sometimes twice, and the lifting hardware is not always swapped to match. Cables and drums come in sizes. A cable must reach from the drum to the bottom corner with the door shut and be heavy enough for the door's weight, and each drum must hold enough wraps for the door's full height.

What a mismatch does

Where a taller door went in but the old drums stayed, the cable runs out of groove near the top of travel and starts winding over itself. Where a cable was cut a little short, the door never settles fully and one corner of the bottom seal stays off the floor. Where a heavier door hangs on light cable, strands give out early at the bottom bracket. Each case ends the same way, with a cable that slips or parts, and fitting new cables of the old size simply sets up the next failure.

Doorup clamps the door where it stopped and takes the tension off the springs before touching anything else. The door's height is measured and its weight read from the spring setting, and those two figures decide the drum size and the cable length and thickness. Both cables are fitted new, the drums are set so each takes up its cable at the same moment, and the springs are wound back until the door holds still at mid-height. The general method, including what happens when a door has left its track, sits on the garage door cable repair page.

• With the door closed, see whether its top edge sits level. A low corner usually points to the cable on that side.
• From a safe distance, check whether either cable is wrapped outside the grooves of its drum.
• If the door is stuck open, leave it open and park on the street or driveway rather than forcing it down.
• If you know the door was replaced at some point, mention roughly when; it helps explain a cable that keeps riding off.
• Keep hands away from the drums, the bottom brackets and the screws holding the drums to the shaft. Every one of them holds spring tension.
