Cary runs about 6,342 households, with a median income of roughly $109,790 - close to the $110,450 median across the broader 209,522-household service area, which tells you this isn't a pocket of either unusually old or unusually new construction. It's solidly mid-80s, and that consistency matters for parts: when a torsion spring or opener gear fails here, it's almost always sized to the same handful of door and track specs the whole area shares, not the wider range of models you'd find across 58 named areas spanning six decades of building. Most of the houses on these streets are owner-occupied, which lines up with the territory-wide pattern of roughly 125,448 owner-occupied houses out of 209,522 households - the kind of stable, long-tenure ownership where people fix a door rather than walk away from it. That stability also means a lot of these doors and openers are original replacements, not the builder-grade units from 1985, which changes what we expect to find before we even open the panel.
