Brookhaven has 24,467 households, smaller than the 133,325 households spread across the full service area, but with a noticeably higher median income - $117,448 here against $91,308 territory-wide. That income gap tends to track with build quality and with how often an opener or spring has already been upgraded once rather than left original to the house.
Newer median build year plus higher income usually means more of the garage doors in Brookhaven have already seen one opener swap, possibly a chain-to-belt change, and insulated steel panels rather than the thin single-layer steel common on older stock. It doesn't mean nothing breaks. Springs wear out on a cycle count, not a calendar, and a 1990s door that's been opened twice a day for thirty years has put the same miles on its torsion spring as an older door would.
