Hurricane Season Cleaning Prep: Protect Your Jacksonville Home

Why Hurricane Season Demands a Different Cleaning Strategy

If you've lived in Jacksonville for any length of time, you know hurricane season isn't a maybe — it's a when. From June 1 through November 30, our corner of Florida sits squarely in the crosshairs of tropical systems. The 2024 season alone brought three named storms within 200 miles of Duval County.

When a hurricane threatens, the last thing you want is a home already harboring moisture problems, clogged gutters, or unsealed surfaces that let water infiltrate.

Preparing your home for hurricane season isn't just about boarding up windows. The cleaning and maintenance you do before storm season directly determines how much damage your home suffers — and how fast you can recover afterward. Clean Fix Jax has spent over 15 years helping Jacksonville homeowners clean up after storms, and the homes that were properly prepped always fare dramatically better.

Pre-Season Cleaning Checklist (Do This by May)

Gutters and Downspouts

Clogged gutters are the number one cause of water intrusion during hurricanes. When 4-6 inches of rain falls in 24 hours — which happened three times during the 2023 season in Duval County — your gutters need to move water fast.

Leaves, pine needles, and oak tassels (Jacksonville's signature gutter-clogger) create dams that force water under your roofline and into your walls.

• Clean gutters thoroughly by mid-May — remove all debris by hand or with a gutter scoop, then flush with a hose to check for proper drainage
• Inspect downspout connections — make sure they're securely attached and directing water at least 4 feet from your foundation
• Install gutter guards if you have oak trees within 50 feet of your home — they reduce debris by 80% and cost $6-12 per linear foot installed
• Check for rust spots and separations — even a small gap between gutter sections can dump hundreds of gallons of water next to your foundation during a storm

Window and Door Seals

Wind-driven rain finds every gap in your home's exterior. In a Category 1 hurricane, rain can be driven sideways at 74+ mph, forcing water through cracks you didn't even know existed.

• Clean all window tracks and weep holes — dirt and debris block drainage channels, causing water to pool and seep inside
• Inspect and replace weatherstripping on doors and windows — if you can see daylight through a closed door, water will get in during a storm
• Re-caulk any gaps around window frames and door frames — use silicone caulk, which remains flexible and waterproof for 15+ years
• Clean and lubricate hurricane shutters — corroded tracks and stuck shutters are useless when you need them in a hurry

Interior Moisture Defense

Reduce Existing Humidity Before the Storm

If your home already runs at 60%+ indoor humidity during summer (common in Jacksonville homes without dehumidifiers), a hurricane will push it to 80%+. That's the danger zone for rapid mold growth.

• Run dehumidifiers continuously from June through November, targeting 40-50% indoor humidity
• Service your HVAC system before storm season — a properly functioning AC removes 15-20 gallons of water per day from indoor air
• Clean bathroom exhaust fans — pop the cover off and vacuum the dust buildup. A clogged fan moves 50% less air, leaving moisture in your bathroom
• Check attic ventilation — attic temperatures above 130°F combined with hurricane moisture create ideal mold conditions in as little as 48 hours

Pre-Storm Interior Prep

When a storm is 48-72 hours out, do these critical cleaning tasks:

• Clean and disinfect all surfaces — mold grows fastest on dirty surfaces, so a clean home resists mold longer after water intrusion
• Move furniture 2-3 inches away from exterior walls — this allows air circulation if water gets in and prevents mold from growing behind furniture
• Wash all towels and bedding — clean, dry linens stored in sealed bags are invaluable after a storm when your washer may be out of commission
• Clean out your refrigerator — if you lose power for 3+ days (common after hurricanes in Orange Park and St. Augustine), everything in your fridge becomes a biohazard
• Run your garbage disposal with ice and vinegar, then pour baking soda down the drain — you don't want a smelly disposal when power returns

Post-Storm Cleanup Protocol

First 24 Hours

The clock starts the moment the storm passes. Mold can begin growing on damp surfaces within 24-48 hours in Jacksonville's climate, so speed is everything.

• Document all damage with photos and video before you touch anything — your insurance company will need this
• Remove standing water immediately — use a wet/dry vacuum, mop, or towels. Every hour water sits, it penetrates deeper into walls and flooring
• Open windows and doors to ventilate if the rain has stopped — air circulation is your best weapon against mold
• Start fans and dehumidifiers as soon as power is restored — place them strategically to create airflow across wet areas

Days 2-7

• Clean all hard surfaces with an antimicrobial solution — 1 cup bleach per gallon of water works for non-porous surfaces; use an EPA-registered antimicrobial for porous materials
• Dry out wall cavities — remove baseboards and drill holes in the drywall near the floor to allow air circulation inside the walls. This is critical — mold inside walls is the most common hidden damage
• Discard any porous materials that have been wet for 48+ hours — carpet, carpet padding, drywall, and insulation that can't be dried within 48 hours need to go
• Clean and treat HVAC ducts — if your home flooded, your ductwork likely took on water and needs professional cleaning before you run the system

When to Call Professionals

If your home took on more than an inch of standing water, if you see mold covering more than 10 square feet, or if the musty smell persists after a week of drying, you need professional help.
