Springs fail on a schedule, not by accident - every torsion or extension spring is rated for a cycle count, and a door opened twice a day for close to seventy years has put a lot of cycles on hardware that was never meant to last forever. With a median build year of 1955, a large share of Bayonne's garage doors are running original or first-replacement springs well past any reasonable service life.
Cold makes it worse. This area sits in a severe cold climate band, and steel spring wire loses flexibility as temperatures drop, so the first hard freeze of the season is when a spring that's been weakening for years finally lets go. It's not a coincidence that spring-repair calls cluster in the cold months.
Across the broader service area - 1,057,409 households and 294,747 owner-occupied houses, most in stock built before 1960 - this is a common failure, not a rare one. Bayonne, at roughly 28,325 households, carries its share of it.
