Nederland's housing stock centers on 1973, squarely inside the 1966-1998 range that built out most of this part of the service area. A door and track system installed then, or replaced once in the 80s or 90s, is running steel roller track and stamped brackets that were never designed for today's heavier insulated sections. Bolt a modern door onto that original track and the tolerances are tighter than the hardware ever intended - one bump and the roller pops the rail.
Add the climate: mild most of the year with occasional freeze events, which means the track brackets aren't fighting extreme temperature swings, but they are fighting decades of thermal cycling that's slowly loosened lag screws nobody's checked since installation. That's the quiet cause behind a lot of the off-track calls we see out this way - not a single dramatic event, just hardware that's had 50 years to work itself loose.
We cover this from Beaumont, about 12 miles out, so we're not guessing at what Nederland's garages look like - we're planning around the same build era that shows up across most of this side of the service area.
