The climate band here is cold-moderate, which doesn't mean brutal winters, but it does mean enough temperature swing through the year to work on old caulking, old weatherstripping, and old steel finishes. Combine that with a median 1965 build year and you get the failure pattern we see most in this part of the service area: bottom panels rusted through at the seam, hardware seized from decades of the same grease never refreshed, and springs well past any reasonable service life because nobody ever replaced the door, just kept fixing it. New installation here isn't about chasing a trend, it's about replacing a door that's been patched past its limit on a house that was never built for the doors sold today.
