The service area sits in a severe cold climate band, and steel springs lose temper faster when they cycle through hard freezes every winter. On a door that's been opening and closing since the early 1960s, that fatigue adds up. Extension springs in particular tend to go without much warning, since there's no torsion bar flexing to telegraph the wear the way a modern setup does.
Fruitport's income profile also plays into what we see. Median household income here runs $80,769, well above the $62,575 median across the wider service area covering all 16,402 households. In practice that means more owners here choose a full hardware upgrade - torsion conversion, insulated panels - rather than patching a 1960s door back together one more time. Both are legitimate calls. We'll tell you which one the door in front of us actually supports before you decide.
