Garage door questions, answered for Sullivan

Sullivan sits in Missouri's humid subtropical region — a humid subtropical climate — long, hot, muggy summers, mild winters, heavy thunderstorms, and high year-round humidity. That's hard on a door: high year-round humidity that rusts springs, cables, and fasteners and summer heat and moisture that swell wood doors and seize rollers all accelerate wear on springs, seals, and openers, so the failures we see most here are rusted track hardware and seized rollers and swollen, sticking wood doors in summer humidity. We size springs and seals for local conditions, not a generic catalog spec.

Most Sullivan homes were built around 1974, and 59% predate 1980 — so a lot of doors are still on their original springs and openers, well past rated cycle life. We check door balance and hardware age on every visit.
