Crystal's housing is older than the broader picture across the service area. Median year built here runs around 1959, well ahead of the service area's overall median of 1975 - meaning a lot of these garage doors and their hardware have had more decades of winters to wear through. The region sits in a cold-severe climate band, and repeated freeze-thaw cycles stiffen torsion springs, swell wood jambs the door has to seal against, and corrode cable ends faster than a mild climate would. A spring rated for a certain number of cycles doesn't care about the calendar - it cares about how many times it's been wound and released, and an older door that's been opened daily for six decades has used up a lot more of that life than one installed in 2015.
With roughly 9,307 households in Crystal and a median income near $86,752, this isn't a neighborhood where everyone's doing ground-up garage renovations. Most owners are maintaining what's there, which means the original-era hardware sticks around longer than it would in a market full of new builds.
