Cable Repair for Ocean City's 1970s-Era Garage Doors

We don't have a flat number to quote here, and we're not going to make one up. What drives the price on a cable job is whether both cables need replacing at once (they usually should, since they wear at the same rate and age), whether the drums or the bottom brackets are also rusted through, and whether the door is a standard single-car width or the wider double sections common on homes built out this way. A straight cable swap on a door that's otherwise sound is a different job than one where the cable snapped because a drum seized and chewed through the bracket on its way down.

The spring, not the cable, is usually what turns a simple job into a bigger one. On a door this age, if the torsion spring hasn't been serviced, it's working at the edge of its rated cycle life, and a cable failure often happens at the same time the spring is giving out, not because of it. Pulling a dead cable off a fully loaded spring without releasing tension properly is how fingers get hurt, and it's also how a drum cracks under uneven load. We see doors out this way where a homeowner or a handyman swapped the cable but left the spring alone, and it failed again within months. If we're out at a house in Ocean City for a cable, we check the spring before we call the job done, because a second trip eight miles each way doesn't help anyone.

A frayed or broken cable usually announces itself one of two ways. Either the door won't lift at all and sits crooked in the track, hanging lower on one side than the other, or it lifts partway and then stalls, with the opener motor straining against a door it can't fully raise. Sometimes you'll hear a loud snap, then a metallic whipping sound as the loose cable end slaps around inside the track. If a door built in the mid-1970s on this side of the service area has never had the cable replaced, that cable is well past the point where fraying is likely, and it's worth a look even before anything breaks.
