In a Florida home, the sliding door is the largest piece of glass in the building envelope — which makes it, every June, a structural question as much as a convenience. Most hurricane door failures are not exotic: they are worn rollers, tired locks, clogged sill drains and unlatched panels meeting weather they would have survived in good order. This is the preparation that puts your doors in good order.
Start with the sill drains
The least glamorous and most consequential item: your sill track is designed to collect water and weep it outside through drain slots. When those drains clog with the year's grit, leaf matter and — during the storm itself — wind-driven debris, the track becomes a trough that fills and overtops into the room. Before the season: clear the track completely, find the weep holes at the sill's ends, and flush them until they run free. During the season, after any serious blow, check them again. More Florida sliding door "leaks" are drain failures than glass or seal failures, and drains are a ten-minute fix on a calm Saturday.
Locks, latches and the panel that must stay shut
Storm pressure works a door in both directions, and a latch that barely catches in June is a latch that lets go in a September gust — after which the panel is a sail in a broken opening. The pre-season check: the primary lock must engage fully, proven with a hard pull; the keeper screws must be snug; and the panel must not be liftable — anti-lift clearance checked and corrected, because wind uplift is a real derailment force on a rattling panel. If your lock has been in the "needs a lift and a jiggle" era, hurricane season is the deadline to end it; our lock guide lays out the causes, and none of them improve under storm load.
Rollers and tracks: the door must move to be secured
Counter-intuitive but true: a door that cannot move properly cannot be secured properly either. Panels are latched, barred and shuttered from their closed position; a door grinding on flat-spotted rollers gets left three inches open by a tired homeowner at exactly the wrong moment. Pre-season is also when shutters and panels are test-fitted — do yours still mount cleanly, are the tracks and frames they anchor to sound? Add the doors to that drill: full travel, clean close, positive latch. Anything that fails gets serviced in the calm months, when our roller and track schedule — and everyone else's — still has room in it.
Screens: the sacrificial layer
Screen doors and storm winds do not negotiate. The standard Florida practice stands: screens come off or get secured per your shutter plan before a storm's arrival, because a screen panel in a gale is debris with a frame. Between storms, screens earn their keep — and the pre-season is when a torn screen should be rescreened rather than left to unzip in the first squall. Frame condition matters here too: the checklist takes five minutes per door.
After the storm: the inspection order
When the weather passes: check the tracks for debris and standing water first, drains again, and operate each door slowly through its full travel before forcing anything — grit and small debris in a track will score it and chew rollers in a single forced pass. Inspect the seals for wind-driven rain intrusion points, note any new fogging in glass units (impacts and pressure flexing can finish a tired seal), and check locks and keepers for shifted alignment. Doors that took a direct debris strike get a professional look before they return to daily duty. We run post-storm assessments across our Florida coverage every season; the pattern never changes — the doors that were maintained ride it out, and the doors that were "going to get looked at" become the emergency queue. June's version of that sentence is a choice, and it is yours.
