Flooded House: What to Do After the Water Gets In
After a house floods: wait until the water stops rising, treat everything it touched as contaminated, photograph the high-water line inside and out, and report the loss to the flood insurer the same day — most homeowners policies do not cover rising water. Pump-out and drying come after the record, not before.

Is the house safe to go back into?
Not until three questions have good answers. Has the water stopped rising? Re-entering during the rise means wading into water that may be electrified or moving. Is power to flooded levels off? A breaker panel that took water, or circuits still live under water, make the floor itself the hazard — if the panel is wet, that is the utility's or an electrician's problem, not a flashlight job. And is the structure sound? Doors that will not open, new sagging, or shifted piers are reasons to stay out. Floodwater itself is the third hazard: whatever the street, the marsh, and the storm drains carried came inside with it, so skin contact and anything it touched are treated as contaminated until disinfected.
What does storm surge do that rain does not?
Rain falls clean and floods from the top down; surge arrives loaded and floods from the bottom up. Charleston does not need a hurricane for the second kind — the National Weather Service has logged coastal flood events at theCharleston Harbor tide gauge since 1921, many driven by nothing more than a king tide and an onshore wind. When surge or tidal water reaches a house it goes under it first: thecrawl space floods before the floor does, soaking insulation and ductwork that stay wet long after the yard drains. It also leaves salt and sediment in materials, which is part of why soaked porous material after a surge event is usually removed rather than dried in place.
The first day, in order
- Photograph the high-water line inside and out before it fades, plus every room the water reached.
- Record make, model, and serial numbers of flooded appliances and electronics — the NFIP asks for them in the claim.
- Report the loss to the flood insurer as soon as possible, per the sequence at floodsmart.gov.
- Start pump-out and drying — standing water is the multiplier on everything that follows. Emergency water removal is the first trade on site.
- Keep samples of removed carpet, flooring, and curtains for the adjuster, and keep every mitigation receipt.
- Do not run the HVAC if ducts or equipment took water — it spreads contamination through the house.
Which insurance responds to a flooded house?
For rising water, only a flood policy — NFIP or private.FloodSmart states it without hedging: most homeowners insurance does not cover flood damage. The homeowners policy still matters after a storm, because wind-driven rain through storm-created openings is its territory, and both kinds of damage can share one Charleston house. The flood claim runs on its own track — adjuster inspection, four to eight weeks to payment once finalized, checks naming the mortgage holder — and its evidence standard is set by what was documented on day one. How water damage claims work in SCwalks both tracks in detail.
What comes out, and what can be saved?
The dividing line is porosity. What floodwater soaked and can absorb contamination — carpet and pad, upholstered furniture, mattresses, drywall and insulation below the water line — typically comes out. Hard, cleanable surfaces — framing, masonry, solid-surface floors, metal and hard plastic — are usually disinfected and dried in place. The EPA's numbers explain the urgency: mold can establish on damp materialswithin 24 to 48 hours, and past roughly10 square feetof growth the EPA points to professional remediation. This is Category 3 work end to end —flood damage restoration exists as its own trade precisely because post-surge cleanup is a contamination job, not a mopping job.

|---|---|---|
| 1921 | First year in the NWS coastal flood event database for Charleston Harbor — tidal flooding here predates every current policyholder | NWS Charleston |
| June 1 – Nov 30 | Atlantic hurricane season — the window when surge risk, provider demand, and adjuster backlogs peak together | NOAA NHC |
| 24–48 hours | Window before mold can establish on damp materials | EPA |
| 4–8 weeks | Typical time from finalized NFIP claim to payment | FloodSmart |

01What should I do immediately after water damage?
In flood terms: nothing inside the house until the water stops rising and power to flooded levels is off. Then document — the high-water line, every room, serial numbers on appliances — before anything is moved or pumped. Then notify the flood insurer, and only then start pump-out and drying, keeping samples of removed carpet and flooring for the adjuster as the NFIP recommends. Document, notify, mitigate: that order protects both the house and the claim.
02Who can remove water from my basement?
In Charleston the question usually needs translating: the metro builds on crawl spaces, not basements, so post-storm water sits under the floor rather than below grade in a finished room. The work is the same trade either way — extraction providers with pumps and drying equipment. The 24/7 line on this site routes Charleston-metro homeowners to an independent provider that handles pump-out, whether the standing water is in a rare Lowcountry basement or the crawl space under the house.
03How long does it take for a crawl space to dry out?
After a flood, longer than the rooms above it — floodwater arrives there first, drains from it last, and Charleston humidity keeps refilling the air that is supposed to be doing the drying. Passive drying through vents can take weeks and often stalls entirely in summer; forced drying with extraction, plastic removal, and dehumidification typically runs days instead. What decides it: how much water stood, for how long, and whether wet insulation and debris were removed or left in place.
