Garage door questions, answered for Greencastle

Greencastle sits in a humid continental climate — hot, humid summers and cold, snowy winters, with sharp freeze-thaw swings between seasons. That is hard on a door — wide seasonal swings that work bolts loose over time, cold-thickened opener grease that strains the motor, and humid summers that seize hinges and rollers all accelerate wear on springs, seals, and openers, so the failures we see most here are humidity-swollen wood doors in summer, openers straining against cold-thickened grease, freeze-thaw-cracked bottom seals, and loosened hardware from wide seasonal swings. We size springs and seals for Pennsylvania's continental-climate region conditions rather than a generic catalog spec.

Census data puts 65% of Greencastle homes at pre-1980 construction (median build year 1967) — old enough that many garages still run their original springs, opener, and seals, all long past rated life.
