Fruitport's housing stock centers on 1963, which puts most of these garage doors and their original hardware past the sixty-year mark even where panels have been swapped. Springs wear on cycle count, not calendar years, but age still matters for the track alignment, the hinges, and the bolts holding the whole assembly to framing that has settled over six decades.
The region sits in a severe cold climate band, and that's the other half of the story. Steel contracts in deep cold, grease stiffens, and a spring that was fine in August can bind or snap in January. Doors here see more freeze-thaw cycling at the bottom seal and track than a door in a milder climate would, which is why weatherstripping and track lubrication wear faster than most owners expect.
Put those two things together - 1960s hardware and a cold climate that's hard on steel and grease - and you get the two most common calls from this area: a spring that lets go in winter, and a track that's pulled slightly out of alignment from years of seasonal movement. Neither shows up overnight. Both show up on a maintenance check before they show up as a call at 6 a.m.
