Pre-Hurricane Home Checklist: 12 Steps to Limit Water Damage Before the Storm

As winds increase within the 48-to-24-hour window, atmospheric pressure drops and driving rain attacks building fenestrations. Wind-driven rain can penetrate microscopic gaps that shed normal vertical showers with ease:

4. Clear and Test Sliding Glass Door Weep Holes: The vast majority of Orlando homes feature multi-panel sliding glass doors leading to lanais. These door tracks rely on miniature external weeping channels to drain wind-driven water. If clogged with sand or debris, hydraulic pressure forces rainwater over the interior track threshold, soaking adjacent subflooring and baseboards. Use a stiff wire to ream out weep slots. 5. Deploy Impact Protection or Accordion Shutters: Flying debris piercing a single window causes explosive interior pressurization that lifts roof trusses and allows hundreds of gallons of rainwater to inundate ceilings. Secure all engineered shutters, or bolt five-eighths-inch exterior-grade CDX plywood using approved masonry anchors. 6. Inspect Window Frame Caulking: Wind-driven rain driven at 60 to 90 mph finds compromised perimeter caulking along window-to-stucco junctions. Apply paintable polyurethane elastomeric sealant to any separated joints.

During the final 24 hours before tropical-storm-force winds arrive, property owners must secure mechanical systems and exterior water bodies to prevent catastrophic structural interaction:

7. Manage Swimming Pool Water Levels Correctly: Never completely drain an inground swimming pool in Florida before a hurricane. As torrential rains saturate surrounding soils, the rising water table exerts intense hydrostatic buoyant pressure that can literally pop an empty fiberglass or concrete pool out of the ground like a cork. Instead, lower the water level by only 6 to 12 inches to accommodate rainfall without overflowing into the house patio, and turn off pool pump electrical breakers. 8. Test Sump Pumps and Battery Backups: For lakefront homes, sunken rooms, or daylight basements, test sump pit float switches by manually pouring five gallons of water into the basin. Verify marine battery backup systems engage seamlessly when AC wall power is disconnected. 9. Elevate Sensitive Ground-Level Belongings: If your property sits in a low-lying Central Florida retention basin, lift Persian rugs, ground-level electronics, musical instruments, and low-sitting furniture onto concrete pavers or second-floor living spaces.

In the final hours before hurricane landfall, simple interior plumbing precautions protect against hidden indoor floods while you focus on life safety or evacuation:

10. Shut Off the Main Municipal Water Supply Valve: If you plan to evacuate to a shelter or inland hotel, always close the primary water shutoff valve at the exterior hose bibb or water meter curb box. High winds can tear an outdoor hose bibb from the wall or collapse an overhead roof beam onto an attic water pipe; shutting off the main eliminates pressurized flooding while you are away. 11. De-Energize Electric Water Heater Breakers: When shutting off main water, always flip the dual-pole 30-amp water heater circuit breaker to 'OFF.' If supply lines siphon dry during municipal pressure drops, energized heating elements will burn out instantly and can rupture the tank lining. 12. Execute the Comprehensive 360-Degree Video Walkthrough: Under Florida's post-SB 2-A insurance regulations, the burden of proof rests squarely on the policyholder. Spend 15 minutes taking a continuous, high-definition video walkthrough of your entire home—narrating date, time, and zooming in on pristine ceilings, baseboards, and electronics. This pre-loss documentation provides indisputable legal proof against insurance adjuster claims of 'pre-existing moisture damage' or 'deferred maintenance.'

Once the storm passes and local emergency management authorities declare it safe to inspect your property, the recovery clock begins immediately. Under Florida Statute § 627.70132 and standard HO-3 policy conditions, homeowners maintain an affirmative legal duty to mitigate further property loss.

If wind has peeled back shingles, blown off roof ridge vents, or shattered a window, immediate emergency tarping and board-up are mandatory to prevent secondary interior rain saturation. Do not wait for an insurance adjuster's field inspection to begin drying. Engage an IICRC-certified restoration contractor within the first 24 hours to extract pooling water, set up commercial Low Grain Refrigerant (LGR) dehumidifiers, and log psychrometric readings. Professional contractors provide time-stamped moisture mapping and detailed Xactimate scopes that segregate covered windstorm damage from flood perils, ensuring policyholder claims receive full compensation without statutory compliance disputes.
