How It Shows Up
A cable problem rarely announces itself cleanly. The door might tilt to one side as it rises, dragging one bottom corner while the other corner keeps moving. You'll hear a snap or a loud pop, then the door either won't budge or drops hard and fast on one side. Sometimes it's slower: the cable frays strand by strand where it wraps the drum, and you notice small wire hairs near the bottom bracket weeks before it lets go. Given the age of housing stock out here - median year built 1991 - a lot of these cables have never been swapped, which is long enough for the zinc coating to wear thin at the friction points even without a heavy freeze cycle. The climate here runs mild with occasional freezes, so corrosion isn't the main driver the way it would be in a wetter or colder region, but three decades of daily cycling wears cable down regardless of weather.
What Can Go Wrong
A snapped cable on one side lets the door hang crooked, and if you keep running the opener against that imbalance you can bend the track or crack a panel at the corner. On older torsion setups the drum itself can crack from age, and once that happens the cable has nothing to wrap around evenly, so it walks off the drum and jams. On the extension-spring style doors common in this era, a snapped cable under tension can whip - that's the one we ask you to just step away from and call rather than try to wrangle yourself. One honest limitation: if the drums are original from a 1991 install and one side is worn, we'll usually recommend replacing both drums and both cables as a pair, not just the broken one, because the other side is close behind it. Patching only the failed side is cheaper today and often means a second call within a year.
How to Book
McQueeney runs about 20 miles from our San Marcos base, so we schedule cable jobs out here alongside other work in the area rather than treat it as a standalone run - tell us what you're seeing on the phone and we'll fit the trip in. See who else we reach nearby at /near/mcqueeney/, or if what you actually need is a broader look at cable repair across the wider San Marcos area, that's covered at /garage-door-cable-repair-san-marcos-tx.
