Destin sits in a mild climate band with occasional freeze risk, which sounds easy on a garage door until you add the humidity and salt air off the Gulf. That combination doesn't crack panels the way a hard freeze-thaw cycle does further north - it corrodes. Steel panels on homes built in the 1970s and 80s, especially in the older pockets of the service area, show rust bubbling at the bottom panel seams and around the weatherstrip retainer long before the door itself is mechanically worn out. Torsion springs and end bearings on the same vintage homes seize up from humidity rather than cold, so the failure you get here is a stiff, grinding door rather than a snapped cable. Newer construction built since the 1990s and 2000s tends to have galvanized hardware and better seals, so if your house is on the newer end of that 1973-2013 build range, you're more likely to need installation because of storm impact to a panel or an opener giving out than because the door rusted through. Either way, the fix isn't the same fix you'd plan for a drier, colder town, and that's the call we make when we look at the actual door.
