Jupiter's housing stock runs from 1965 to 2021, but the median build year lands around 1981, and across the sixteen named areas we cover - from Abacoa down to Admiral's Cove - most of what's standing went up in the 1980s and 90s. That matters because a garage door spring is rated in cycles, not years, and a door installed when a house was built in 1981 or 1988 has usually burned through its rated life twice over by now. Nobody swapped the spring when the house changed hands; it just kept opening until it didn't.
The climate band here is mild temperate, which is a break from places that fight hard freezes or heavy salt-ice cycles - but mild and steady still means steady wear on galvanized coating, steady humidity on bearing plates, and steady use on hardware that was never meant to run thirty-five years without a look. We don't see doors failing from one bad storm. We see them failing because the torsion spring, the rollers, and the cable drums have all been quietly giving up ground since the Reagan administration and nobody noticed until the door wouldn't lift.
If your house falls in that 1980s-90s band, the original springs and the original opener are both candidates for failure, and often it's not one part - it's the whole assembly reaching the same age at the same time.
