Median household income across the wider service area sits around $131,283, but SeaTac's own number is closer to $76,517, and with roughly 11,772 households in this specific area, a lot of garage door decisions here come down to fixing what's there rather than replacing it outright. Housing built around 1971 puts SeaTac earlier than the broader service area's 1962-2005 span with its 1984 median - meaning the average door here has more years on it than a lot of what we install further out. Add a mild climate with occasional freeze, and the failure mode isn't ice-locked doors, it's decades of cycles on hardware that was never upgraded. That combination - older stock, tighter household budgets, a climate that doesn't force early replacement - is why installs here skew toward doors that finally gave out, not doors swapped on a whim.
