Homer Glen's roughly 8,001 households carry a median income near $128,546, noticeably higher than the $109,064 median across the wider Plainfield service area. In practice that shows up as more owners choosing insulated steel replacement doors once an old extension-spring unit starts costing repeat service calls, rather than patching the same door for another decade.
The other factor is climate, not income. This is a cold-moderate band, and a door built in 1988 wasn't engineered with the same weatherstripping or insulated panel standards you'd find in anything built in the last ten or fifteen years. Cold doesn't break a door on its own, but it accelerates whatever is already weak - a spring near the end of its cycle count, a track already pitted with rust. That combination of hardware era and climate is specific to houses like these, not a generic garage door problem.
