The Symptom
A garage door that drops crooked, hangs with one corner low, or stops a foot off the floor is almost always a cable problem, not a spring problem, though the two get confused. You'll hear a pop, then see slack cable looped loose off the drum on one side while the other side stays taut. Sometimes the door won't move at all because the opener senses the imbalance and refuses to run. In La Marque, where the median home was built around 1978, we see this most on doors that have never had a cable replaced in their working life - the original galvanized cable has simply reached the end of what it can do. Fraying near the bottom bracket or the drum is the tell. If you can see individual wire strands sticking out like a frayed shoelace, that cable is close to failing completely, and running the door again before it's fixed risks the door jumping track or a panel bending under the uneven pull.
Why It Happens Here
La Marque's housing stock centers on 1978, which puts a lot of garage doors here right at the point where original lift cable, drums, and bottom brackets have logged four and a half decades of cycles without anyone touching them. Across the broader service area the housing runs 1978 to 1993, median 1984, so La Marque sits on the older edge of that range - meaning more of what's on the door is the hardware it left the factory with. Add a mild coastal climate that doesn't freeze cable or crack it the way a hard winter would, and a lot of these doors keep working on worn parts far longer than they should, right up until a cable finally lets go on a Saturday morning. It's not dramatic weather damage. It's just galvanized wire that's been winding and unwinding on the same drum since 1978, under slightly more salt air than an inland town gets, and nobody ever had a reason to look at it until it snapped.
How Long You Are Without the Door
We run this job out of Galveston, about 13 miles out, so plan on that drive time before the truck arrives rather than a same-building response. Once we're on site, a standard two-cable replacement with a bracket swap is usually a single visit - we don't leave a door half-fixed overnight. Where it stretches longer is if the drums or track need replacing too, since those aren't always stock items on the truck and may need a short parts wait. Until the cable's replaced, don't force the opener or try to lift the door by hand past where it's stuck; an unbalanced door on a bad cable can come down hard or off its track entirely.
