A cable job in Shorewood almost never starts with age alone - at 1986 median build year, these doors aren't old enough yet for cable rust to be the main culprit the way it is in neighborhoods going back to the 1950s and 60s that make up a lot of the wider service area. What we see instead is fraying from repeated full-cycle use on longer driveways and attached garages, plus corrosion where a cable sits near a floor drain or a door gets left cracked open through a Minnesota winter. The COLD severe climate band this whole region sits in means ice buildup on the bottom panel puts extra load on the cable and drum right when the metal is coldest and least forgiving. Combine that with household incomes in Shorewood running well above the service-area median - $172,325 versus $109,722 - and we also see more two-car, heavier insulated doors here, which means more weight on the cable system than a standard single-car door carries. Heavier door, same cable gauge, more wear per cycle.
