The call we get most from New Cumberland isn't a dead opener, it's a spring that let go overnight on a door nobody's touched since the Eisenhower administration. The median house here was built in 1953, which means a lot of garages still have their original torsion setup or a first-generation replacement from decades back. That hardware wasn't built for today's heavier insulated panels, and when a homeowner upgrades the door but keeps the old spring, something has to give eventually.
Cold is the other half of the story. This area sits in a severe cold climate band, and steel springs lose a measurable amount of cycle life every winter they're stressed below freezing. A spring rated for ten thousand cycles in a mild climate doesn't make it that far here. Combine 1950s-era tracks, decades of settling on a slab, and a hard freeze-thaw cycle, and the failure point is almost always the same: a snapped spring or a cable that's frayed through right at the drum, usually discovered at 6am when someone's trying to leave for work.
