Most of the houses in this part of McLeansville went up in the early-to-mid 1980s - the area's own median build year lands around 1983, right inside the 1968-2002 window that covers garage stock across this whole service area. That means a lot of original cable drums and tracks that have outlived their expected life several times over, on doors nobody's touched since the house was built.
The cold-moderate climate here does its own slow damage. Cable isn't like a spring that snaps under tension all at once - it frays. Cold mornings stiffen the galvanized coating, and over enough winters that coating cracks and lets moisture into the strands underneath. You get a few stray wires poking out near the drum, then one day the whole thing lets go, usually not when it's convenient.
With only 374 households in this pocket of town, the housing here is fairly uniform in age, which means if your neighbor's cable went last year on a house built the same year as yours, yours is probably not far behind. It's not a reason to panic - it's a reason to look at the cable before it looks back at you.
