What to Check
Start at the bottom seal, the rubber strip running along the base of the door. In a house built anywhere near the median year of 1975 for this area, that seal has likely been replaced a few times already, and vinyl breaks down under South Florida sun faster than most owners expect. Run your hand along it - if it's stiff, cracked, or flattened on one side, it's not sealing anymore, it's just decoration.
Next check the side and top seals where the panel meets the frame. On the older one and two-car doors common through this area's 1960s-70s stock, these are often the original thin foam strip, not the thicker bulb seal used on newer installs. Daylight visible around the edges means wind-driven rain during a storm is getting past it too.
Last, check the bottom corners of the slab itself for rust or soft wood if you've got an older wood-composite panel from that same construction era. Standing water from a poor seal finds those corners first. None of this takes tools - a flashlight and five minutes will tell you most of what you need to know before you call anyone.
What Local Conditions Do
Fort Lauderdale sits in a mild temperate band, which sounds gentler than it is for a garage door. There's no freeze-thaw cycle cracking seals the way it does up north, but the seals here take a different kind of beating: constant UV exposure, high humidity, and driving rain off the coast. Vinyl and foam seals harden and shrink under year-round sun rather than snapping from cold, and once they shrink even a little, wind-driven moisture works its way in during any real storm.
Houses in this service area were mostly built between 1953 and 2005, with the bulk from the 1960s and 70s across the 32 named areas nearby - from Wilton Manors and Victoria Park a mile out to North Fort Lauderdale and Harbordale a few miles further. Garages from that build era weren't designed with today's sealing standards in mind, so a lot of them are still running gaps that were acceptable fifty years ago but aren't holding up to current humidity levels. The result is draughts you can feel on a windy evening and water lines on the garage floor after heavier rain, even when the door itself still opens and closes fine.
The Problem
Here's the part that catches people off guard: a garage door that looks fine and opens smoothly can still be leaking air and water constantly. Seals fail quietly. There's no grinding noise, no stuck track - just a slow rise in your garage's humidity and a draught you eventually notice on a windy day. In a climate that stays mild and humid nearly year-round rather than swinging into a dry cold season, that moisture doesn't get a chance to fully dry out between storms, which is part of why we see seal and hardware wear show up earlier here than it would in a drier or colder region.
One honest limitation: we can't restore a seal that's already let years of water sit against the bottom panel and rust the steel underneath. At that point you're looking at panel or door replacement, not a seal fix, and no amount of new weatherstripping changes that math. Catching it while it's still just a stiff seal is the difference between a small job and a full door.
