Garage Door Cable Repair in Point Loma, CA

Nearly a quarter of Point Loma's homes, 22.8%, were built before 1950, and close to three in four before 1980, going by ACS 5-year estimates for 2020 to 2024 across the 12 tracts of the Peninsula planning area. A garage that has stood for seventy years or more has probably held more than one door, and its springs and cables have been changed on their own schedules. Parts from different jobs do not always agree with each other, and the cables are where the disagreement shows.

A cable should be snug whether the door is up or down. If the springs are too weak for the door now hanging there, the cables go slack as the door settles on the floor, and slack cable is what jumps a drum. If the springs are too strong, the door tugs upward and the cables bite hard at the bottom brackets. In both cases the cable is the messenger, and replacing it without correcting the springs brings the same problem back.

With the door clamped and the springs unloaded, the old cables, bottom brackets and drums are inspected; on the peninsula they are also checked for the pitting salt leaves on bare steel. Rusted parts are replaced, and the new cables are cut to the door's height and wound evenly. The door is then weighed against its springs: wound up to the right tension, the door should float at halfway with the opener disconnected, and both cables should feel equally tight. If the springs no longer suit the door, that is said plainly and put right as part of the job. The method in outline is on the garage door cable repair service page.

• With the door closed, look at both cables where they rise beside the door. They should be equally straight; a sag or loop on either side is the early sign of a spring problem.
• Look at the cable loops at the bottom corners for rust bloom or broken wires. Sea air on the peninsula works on them all year.
• Notice whether the door now needs a push from the opener to start, or drifts up by itself. Both are balance changes the cables will feel.
• Do not oil, tighten or adjust the cables, brackets or drums yourself. All of them carry spring force, and a slipping fitting can release it at once.

When a cable has gone slack, frayed or come off its drum, call (619) 666-6054. Doorup keeps that line open 24/7. The Point Loma garage door repair page gathers the other services for the peninsula.
