Most garage doors in Monticello went up around 1997, which puts a lot of houses here at nearly thirty years on the original hardware. Nobody replaces a roller or a cable on a schedule - they replace it when it breaks, and in a town built out in roughly a decade, a lot of doors are hitting that point at the same time. The springs, the end bearings, the lift cable, even the weatherstrip on the bottom panel - if the house hasn't had work done, odds are good none of that has ever been touched. That's not a knock on the builders. Torsion springs are rated for cycles, not years, and a door opened twice a day for 28 years has used up what it was built for whether anyone noticed or not. Add Minnesota's cold - this area sits in a severe cold climate band - and steel parts that were already fatigued get brittle faster once the temperature drops. A spring that would have lasted another year in a mild climate snaps here in January instead. We come out from Elk River, about 12 miles away, so a maintenance visit isn't something we're doing on a whim while we're in the neighborhood - it's worth batching the checklist so one trip covers what a 1997-era door actually needs.
