Charleston's residential garages mostly went up between 1949 and 1993, with the bulk clustered in the 1960s and 70s across the service area's 18 named neighborhoods - that's a lot of original hardware still in service decades past its intended life. Pair that with a cold-moderate climate band and you get a specific failure pattern: steel springs and tracks that tighten up in winter, adding load right at the moment the hardware is already fatigued from age. It's not a coincidence that our busiest weeks tend to follow the first hard cold stretch. Areas like Sissonville, Marmet, and Cross Lanes, sitting a bit further out, tend to have slightly older stock on average, so we see more full spring and track replacements out that way versus opener-only fixes closer into town.
