Florida's mild temperate climate doesn't put Kathleen doors through the freeze-thaw cycling that wrecks hardware up north, so you won't see cracked panels from ice. What you get instead is steady humidity and heat cycling on rubber seals, nylon rollers, and the plastic idler pulleys that were standard equipment on builder-grade door packages in the late 1980s and early 1990s. Those parts were never meant to last forever, and a door built in 1990 is now old enough that the original rollers and pulleys are usually the first things to go. Combined with the area's income profile - median household income here runs around $57,302, a bit under Lakeland's broader $59,346 - a lot of homeowners here have been deferring the smaller fixes, which means by the time we get the call, a sagging roller has already started chewing into the track.
