Seabrook's housing stock centers on 1991, which puts it a notch newer than the broader League City service area, where the median sits closer to 1983. That eight-year gap matters more than it sounds. A house built in 1991 almost always came with a chain-drive opener on a steel rail, and a torsion spring system mounted on a center bracket rather than the older side-mount setup you'd find on an early-1980s build. Doors from this era are usually steel sectional, sometimes with a thin foam layer that's since gone brittle or compressed flat. With 5,545 households in Seabrook, most of them sitting in that same early-90s window, the fixes we see cluster tightly around one generation of hardware rather than spreading across forty years of different systems. That consistency is useful - it means we know what's likely to be worn before we even open the panel. It also means when something is genuinely different (a retrofit opener, a replaced door on original track), it stands out fast.
