Cold-moderate winters mean freeze-thaw cycling is part of life here, and on a door built in 1988 that's 35-plus years of expansion and contraction working on steel seams and weld points that were never meant to last forever. Add in the ordinary stuff - a trailer hitch backed in wrong, a basketball off the rim, a kid's bike left too close - and a single panel takes the hit while the rest of the door, hardware included, keeps running on borrowed time. With median household income in this area running close to $95,625, we see plenty of owners who'd rather fix what's damaged than replace the whole unit, which is a reasonable call as long as the rest of the door is sound.
