This failure pattern is tied directly to when Stuart was built out. With most homes dating 1969-1988 and the bulk of that stock landing in the 1980s and 90s across the twelve areas we work - North River Shores, Sewall's Point, Jensen Beach, Port Salerno, River Park, Hobe Sound, Indian River Estates, White City, Jupiter Island, Fort Pierce South, Tequesta, and Indiantown - a huge share of the area's roughly 19,430 owner-occupied houses are carrying original or first-generation-replacement garage door hardware right now, at the same time.
It's not that Stuart's climate is harsh - mild and temperate is about as easy as it gets on door hardware. It's that the springs, cables, and rollers installed when these houses were framed are all aging out in the same decade. That's a local pattern you won't find in a newer subdivision thirty years younger, and it's why we size trucks and parts inventory around torsion springs and rollers sized for 1980s-vintage doors rather than newer production runs.
