Jenison's housing stock sits at a median build year of 1973, which puts a big share of the town's garages at close to fifty years old. A torsion spring is rated for somewhere around 10,000 cycles - roughly seven to ten years of normal use for most households - so if the door on your 1973-built house still has its original spring, it's running at four or five times its rated life. Same goes for the galvanized lift cable and the steel rollers riding in the track: nobody swapped them because nothing failed loudly enough to force the issue. Cold is what finally does it. This area sits in a severe cold climate band, and steel contracts, grease stiffens, and a spring at the end of its life picks winter to let go rather than July. With 6,528 households in Jenison and a lot of them dating to that same build decade, this isn't a one-house problem - it's the whole street running on the same clock.
