Most houses we work on went up between 1976 and 2012, with the typical build landing around 1993, spread across a dozen named pockets rather than one old downtown core. That means a narrower band of hardware than an older town would have: steel sectional doors on torsion or extension springs and builder-grade openers, not the one-piece wood doors you find in a pre-war neighborhood.
The mix still shifts by area. Closer-in spots like Redstone Arsenal, six miles out, and Triana at eight lean toward the older end of that range, while farther-out areas such as Meridianville and Moores Mill run newer. Across the service area there are 15,816 households, 12,629 of them owner-occupied, so most callers are planning to live with the fix for years rather than patch it for a lease turnover.
Drive those roads and the same door styles repeat because the same handful of builders put them up in the same ten or fifteen year window. We know which springs wear out first on a 1998 double-car door, and the region's cold-moderate climate means winter snaps, not year-round heat, are what finally stress the springs and seals.
