When a door jumps its track in Westwood, it's rarely a clean, simple slip. Most houses here went up around 1973, which puts them right in the middle of the county's 1956-1979 building wave, and that means original steel track sections paired with brackets that were fastened to framing standards from that era, not today's. Fifty-plus years of expansion and contraction on those fasteners means the track itself has usually shifted a hair off true before a roller ever leaves it.
That matters because a door that's off-track on a 1973 build is often fighting two problems at once: the roller that popped, and a bracket that was already loose enough to let it happen. Fix the roller and leave the bracket alone, and the same door comes off track again inside a season. We look at both every time, because on stock this age, one without the other is a callback waiting to happen.
