Garage Door Cable Repair & Replacement

Lift cables are the steel wire ropes that transfer spring tension to the bottom corners of your garage door, guiding it evenly up and down the tracks. When a cable frays, snaps, or jumps off its drum, the door can drop suddenly on one side, jam in the tracks, or place dangerous uneven stress on the springs and opener. Murphy Brothers replaces both cables as a matched set — even if only one has failed — because the second is typically at the same wear stage and replacing only one leads to repeat service calls.

Cable failures in Naples often accelerate due to the salt-air environment corroding the individual wire strands over time. The failure frequently appears subtle at first: a slight fraying visible near the bottom bracket or a cable that has unwound partially from the drum and created slack on one side. Left unaddressed, slack cables can jump the drum groove and tangle around the torsion shaft, significantly complicating the repair. Our technicians inspect cables during every service call and flag early wear so customers can address it before an emergency develops.

Replacing garage door cables requires first releasing and controlling spring tension — a step that demands proper tools and technique. We use spring clamps and locking pliers to safely unload the door before any cable work begins, respool the new cable onto the drum with the correct loop count, and re-tension the springs to factory specification before testing door travel and balance.
