After the Storm: A Jacksonville Homeowner's Guide to Hurricane Season Prep and Safe Post-Storm Cleanup

Most Jacksonville residents remember where they were during Hurricane Irma in September 2017, when storm surge pushed the St. Johns River to a record crest of about 5.6 feet in downtown Jacksonville, according to the National Weather Service, surpassing the previous record set by Hurricane Dora in 1964. Neighborhoods like Riverside and San Marco saw water in streets and, in some cases, homes. The wind was only part of the story. The weeks afterward, with soaked materials, power outages, and swampy humidity, are where homes quietly get damaged the most.

The Atlantic hurricane season officially runs from June 1 to November 30, with the most active stretch typically from mid-August through October. Whether you are bracing for a storm or recovering from one, a little cleaning strategy goes a long way.

This guide is not about heroics. It is about the unglamorous, practical steps that keep a storm from becoming a mold problem, and an honest look at what a cleaning team can and cannot do for you.

Before the Storm: Cleaning Is Part of Preparation

Most preparedness lists cover water, batteries, and documents. Few mention the cleaning side, but it makes the first days without power far easier.

• Run the laundry and dishwasher. If power and water go out for days, you will be glad to have clean linens, towels, and dishes on hand.
• Empty the trash and clean out the refrigerator's oldest items. A fridge full of food during a multi-day outage is a smell problem waiting to happen. Per USDA and FDA guidance, a refrigerator with the door kept closed keeps food safely cold for only about four hours, so check perishables after that and follow the rule "when in doubt, throw it out."
• Clear gutters, drains, and lanai screens. Leaves and debris that block drainage turn heavy rain into standing water against your foundation and door thresholds.
• Stock a small cleanup kit. Heavy-duty trash bags, rubber gloves, rubber boots, N95 masks, microfiber cloths, a mop and bucket, unscented household bleach, and a couple of box fans.
• Photograph every room. Date-stamped photos of your home's condition before a storm make insurance conversations much simpler afterward.

The First 48 Hours After: Safety Before Scrubbing

The urge to start cleaning immediately is natural. Resist it until the basics are safe.

1. Do not enter a flooded home until the power is confirmed off at the main breaker, or the utility has confirmed it is safe.
2. Wear protection. Gloves, waterproof boots, and a mask. Floodwater and storm runoff can carry sewage, chemicals, and bacteria.
3. Document before you discard. Photograph damaged items and materials before removing them, then follow your insurer's instructions.
4. Start drying immediately if you can do so safely. Open windows when humidity allows, run fans, and use dehumidifiers once power returns.

The reason for speed is simple. EPA and FEMA guidance is that wet building materials should be dried within 24 to 48 hours to prevent mold growth, because spores can begin colonizing wet surfaces in that window. In Jacksonville's climate, that window is tight, because the surrounding air is already humid. Keep in mind that this timeline applies mainly to clean water from roof leaks or broken pipes. Floodwater from rivers, storm surge, or sewage needs protective equipment and professional handling regardless of how fast you dry.

Understanding the Type of Water

Not all water in a home is equal, and this is where cleaning and restoration part ways.

• Clean water, such as a supply line break, is the easiest to handle.
• Gray water, such as dishwasher or washing machine overflow, carries some contamination.
• Black water, which includes floodwater from rivers, storm surge, or sewage backup, is considered heavily contaminated.

If floodwater entered your home, porous materials it touched, such as carpet, padding, drywall, and upholstered furniture, generally cannot be safely cleaned and need to be removed. This work belongs to licensed water-damage restoration and mold remediation professionals, not to a house cleaning company. At Shyrley Cleaning we are upfront about that line: we will not pretend a mop and disinfectant can fix a flooded subfloor.

Where Professional Cleaning Actually Helps

Once the structure is dried out and any restoration work is complete, or if your home stayed dry but is covered in storm residue, detailed cleaning is where a home gets back to feeling like itself.

Storm Residue Most People Overlook

• Leaf matter and fine organic debris blown through window seals and door gaps, which settles in tracks, sills, and vents.
• Sand and silt tracked in from outdoors, which acts like sandpaper on hardwood and tile if swept dry.
• Sticky tape and film residue left on windows from storm preparation.
• Mud in grout lines, which stains and is difficult to remove once it dries.
• Dust from post-storm repairs, such as drywall work, roof repairs, and window replacements, which spreads through the whole house.

What a Detail Cleaning Typically Covers

• Wiping down and sanitizing hard surfaces, including counters, door handles, and bathrooms
• Removing dust from vents, baseboards, ceiling fans, and window tracks
• Cleaning interior windows and sills
• Washing and polishing floors, with attention to grout
• Cleaning appliances, especially the refrigerator after a long outage

For homes where repair crews have been in and out for weeks, our post-construction approach applies here too, because the fine dust is the same.

Prevent the Slow Problem: Mold and Lingering Humidity

Even homes that never took on floodwater can see mold appear in the weeks after a storm. Roof leaks, window seepage, and days without air conditioning raise indoor humidity quickly.

• Get the AC running as soon as power returns, and set a dehumidifier to hold interior humidity below about 50 percent.
• Check ceilings, window corners, closets, and the back of furniture against exterior walls.
• If your HVAC system was flooded or is suspected of water damage, have it inspected before running it.
• Do not paint over or bleach a dark spot and assume it is solved. If it returns, or if it covers a large area, call a qualified professional.

Signs It Is Time for a Specialist

• A persistent musty smell that does not fade after drying
• Visible growth larger than roughly a few square feet
• Soft, warped, or stained drywall or ceiling sections
• Anyone in the household with respiratory symptoms that worsen indoors

A Calmer Way to Approach Storm Season

Hurricane season rewards the households that treat it as a process rather than a single event: prepare quietly, stay safe in the first hours, dry things fast, and restore with the right professional for each stage.

A clean, dry, well-maintained home recovers faster. If your home needs a thorough detail clean after repairs, or you want a pre-season refresh so you are not starting from a mess, our team is here for that part of the process.
