Most houses across this part of the service area went up between 1973 and 2013, with the median build year landing around 1979. That matters for springs because a lot of garages still have the original torsion hardware from that era, or a replacement spring that was sized for a door that's since been swapped out for something heavier. Across the seven areas we work, you'll find a solid run of 1960s and 70s stock mixed in with newer construction, and older systems just don't get the duty cycle they used to without the metal fatiguing.
The other piece is climate. Destin sits in a mild band with only occasional freeze risk, so we're not dealing with the deep-freeze snap failures you'd see further north. What we do get is steady humidity and salt air off the Gulf, which doesn't snap a spring outright but does work on the coating over years, pitting the wire unevenly until it's thinner in spots than it should be. A spring that looks fine from the floor can be down to a fraction of its rated wire diameter in the one coil that's going to fail first.
Put those two things together - older hardware plus coastal air - and spring failure shows up earlier here than it would on the exact same door inland.
