The failure pattern in Otsego is tied directly to that 2007-era build wave: a large share of the doors going in needed replacement are hitting that point at roughly the same time, because they went up within a few years of each other. That's different from an older, more mixed-era town where failures are spread out and the hardware itself varies door to door. Here, the springs, the opener models, and the panel styles are more uniform, which is actually useful - it means when we come out for a measure, we're usually dealing with a known category of door rather than guessing. Combined with the area's household income, which sits above the regional median, replacement rather than repeated repair tends to be the financially sound move once a door in this age range needs more than one fix. We're honest when it isn't: a single bad roller or a misaligned sensor doesn't call for a new door, no matter the build year.
