This isn't a generic wear-and-tear story - it's tied to what got built here and when. The twelve communities we cover, from North River Shores and Sewall's Point out to Hobe Sound and Indiantown, mostly went up in that same 1969-1988 window, with a lot of 1980s and 90s stock besides. That means a huge share of the openers in this service area are the same handful of drive types and the same generation of logic boards, all aging out around the same time.
Stuart's climate makes it worse in a specific way. It's mild temperate here - no hard freezes cracking housings or seizing gears - but the humidity is constant, and that's what gets circuit boards, chain sprockets, and steel brackets over the long haul. An opener built for a drier climate corrodes faster here than its spec sheet assumes. Combine 19,430 owner-occupied houses with openers from the same two-decade build era and a climate that corrodes rather than freezes, and you get a steady, predictable stream of the same failure - not a random one.
