The towns on our route - North Hudson, Warren, Roberts, Richmond, Somerset, River Falls, Hammond, New Richmond, Prescott, Star Prairie, Baldwin, Ellsworth - sit in the same broad building window as Hudson itself: construction running from 1972 through 2004, with the median year landing around 1987. That's the era that shaped 13 named areas' worth of garage doors in this service region, and it means a lot of original hardware still in service.
The common fault across that stock is predictable: torsion springs rated for a 1980s-weight door, now fatigued after three and a half decades of a cold, severe winter climate cycling the steel. Steel contracts hard in a Wisconsin cold snap, and a spring already near the end of its rated cycles is the one that lets go on the coldest morning of the year, not the mildest.
