West Virginia's winters put real stress on garage door hardware, and Cassville's opener stock has now logged fifteen-plus years of that cycle - steel rail and chain contracting in the cold, then expanding again, cycle after cycle. On a newer unit that's still mechanically sound, that's usually just noise and a little more resistance in cold months. On a unit closing in on the end of its service life, it's often what finally cracks a worn gear or seizes a dried-out chain. Compare that to the broader service area, where median housing runs back to 1983 across roughly 20,663 households - Cassville's stock is younger, but younger doesn't mean immune, just that the clock started later. At a median household income of $117,643, we also see more owners opting to replace a struggling opener outright rather than nurse a fifteen-year-old unit through another winter, which is a reasonable call once a gear housing starts showing plastic shavings.
