Help with water, flood and fire damage in Hanahan

Hanahan is a compact city, incorporated in 1973, pressed between North Charleston to the west and south and Goose Creek to the east and north. Its limits reach toward the Cooper River and Charleston Harbor, and roughly one of its eleven-and-a-half square miles is water. Low ground and tidal edges mean storms, heavy rain and plumbing failures all deserve a quick, careful response.

If your home has taken on water, smoke or mold, call (866) 937-3230. Fire & Water Energy is a referral service, not a contractor: we try to put you in touch with an independent restoration company that serves Hanahan, and availability depends on local providers.

Tidal water, low elevation and a long FEMA record

With an elevation near 16 feet and tidal water reaching in behind residential streets, this part of the Lowcountry has little margin when tropical rain stalls or a surge pushes up the harbor. Berkeley County has been part of 13 FEMA major disaster declarations since 2000. Recent ones include Hurricane Helene (DR-4829) and Tropical Storm Debby (DR-4835) in 2024, Hurricane Ian in 2022, Hurricane Dorian in 2019, Hurricane Florence in 2018, Hurricane Irma in 2017 and Hurricane Matthew in 2016.

Not every declaration was tropical. The county was also covered for the 2015 Severe Storms and Flooding event, a 2020 outbreak of severe storms, tornadoes and straight-line winds, and a 2014 Severe Winter Storm, a reminder that ice and freezing pipes occasionally reach the coast too.

What usually soaks Hanahan floors and walls

Outside of storm season, most indoor water losses here trace back to everyday sources: a supply line under a sink, a washing machine hose, a water heater at the end of its life, or an air handler whose condensate drain clogs during the long cooling season. Wind-driven rain finding a gap in flashing or shingles is another frequent culprit. Newer areas such as Tanner Plantation and older streets alike can see these problems.

For water damage restoration in Hanahan, a sound contractor will usually stop the source, extract standing water, measure moisture inside walls and subfloors, and run drying equipment until readings reach normal. Ask how they document progress. If a ceiling is sagging or stained, our page on ceiling water damage repair explains what to expect.

After a house fire: soot, odor and firefighting water

The city maintains three fire stations, but even a quickly extinguished kitchen or dryer fire can leave a film of soot on every surface and an odor that clings to drywall, cabinets and clothing. Water used to put out the fire then adds a second layer of damage.

Companies that handle fire damage restoration commonly board up openings, remove charred materials, clean residue with methods matched to the type of soot, and deodorize with air scrubbers or similar equipment. Get the scope in writing, and keep damaged items until your adjuster has seen them.

Storm surge, heavy rain and fallen limbs

Berkeley County's GIS mapping includes FEMA flood data and hurricane surge layers you can check by address, which is worth doing before the season starts. The county also participates in the National Flood Insurance Program, and its floodplain page notes that a new flood policy typically takes effect 30 days after purchase, so waiting until a storm is named is usually too late.

When water does come inside, flood cleanup generally means pumping out water, removing soaked drywall and insulation, cleaning and disinfecting, then drying the structure. Roof punctures and downed trees fall under storm damage cleanup, which often starts with emergency tarping.

Keeping mold out of damp Lowcountry homes

Coastal humidity slows natural drying, so wet carpet pad, baseboards and crawlspace insulation can start growing mold within a day or two. The county recommends keeping crawlspace vents open on at least two sides and gutters clear, both of which help keep moisture away from framing.

EPA guidance says a homeowner can usually tackle a moldy patch of about 10 square feet or less. Larger growth, mold inside wall cavities, or mold following contaminated floodwater calls for mold remediation with containment and HEPA filtration.

First moves for Hanahan households after damage

• Call 911 for fire, injuries, a gas smell or anyone trapped.
• Do not walk or drive through floodwater; the county warns that just six inches of moving water can sweep you away.
• Shut off power to wet areas only if you can reach the panel without standing in water.
• Sign up for Berkeley County alerts and check the county road condition report before driving after a storm.
• Photograph damage, save receipts and contact your insurer or agent; what is covered depends on your policy, and flood usually needs a separate policy.
