This isn't a generic wear-and-tear story. It's specific to what's actually built out here. With most of the service area's roughly 12,994 owner-occupied houses dating to the 1980s and 90s construction wave, a big number of garages share the same original hardware generation - meaning the same springs, same track gauge, same panel thickness are all aging out around the same time. Add a moderate heat climate band that puts steel and nylon rollers through real expansion and contraction every season, and you get a predictable failure pattern: warped bottom panels, tracks that have walked out of alignment, and openers original to houses now pushing thirty years old.
A newer subdivision doesn't see this same clustering - the hardware there is younger and more uniform. In Katy's older pockets, though, replacement isn't optional maintenance, it's catching up with a house that's finally at the end of what its original door and opener were built to do.
