Flooded in Charleston or the Kanawha Valley? The honest first 48 hours

On August 16 and 17, 2026, three rounds of heavy rain dropped more than 4 inches at Charleston's Yeager Airport in a single day, sending creeks over their banks across Kanawha County — from Cross Lanes and Sugar Creek to Cabin Creek and the neighborhoods along Greenbrier Street. Emergency crews logged more than 50 water-rescue calls, and the ground was already soaked from July's storms. If your home took on water, here's the honest version of what to do next: dry everything within 24–48 hours of the water leaving, document it, and don't sign a big remediation contract while you're still wet and stressed. Many homes that dry out fast need no professional remediation at all.

Do these things in the first 24–48 hours

  1. Stay safe first. Never drive or walk through moving water, and be careful re-entering a flooded lower level. Inside, don't wade near outlets or your electrical panel — and if your power is still out, remember a generator never belongs indoors or in a garage. Water that came down a hillside or through the streets can carry contaminants; limit skin contact and wash up after handling wet items.
  2. Get the water and mud out, then start drying. Remove standing water, shovel and hose out silt while it's still wet, then move air across every wet surface and run a dehumidifier if you have one. If you have central air, run it — cooling the air wrings moisture out of it. On a humid August day, opening the windows can actually bring more moisture in than it removes. The goal is fully dry within about 48 hours of the water leaving.
  3. Pull up what traps water. Lift soaked rugs and carpet padding; move furniture off wet floors. Check the bottom foot of walls, baseboards, and inside lower cabinets — and if you have a basement or crawl space, check it now (more on that below).
  4. Document everything. Take dated photos and video before you clean up or throw anything away — for insurance, for any state or federal assistance that applies to your county, and for your landlord if you rent.
  5. Then decide on help. Once the water is out, get an honest read on whether you can finish drying yourself or need a pro (see the triage below).
The honest move: you may not need to spend anything. The first two days are about drying, not testing and not contracts. A home dried fully within ~48 hours often needs no remediation. Save the test kit — and the big decisions — for after things are dry.

Flash floods move fast — that's bad news and good news

This was flash flooding, not slow river flooding, and that changes the math in your favor. Water that came and went in hours hasn't soaked as deep as water that sat for days — hard floors, concrete, and framing can usually be cleaned and dried in place. The catch in the Kanawha Valley is what the water carried: runoff funneled down hollows and hillsides arrives loaded with silt, and drying can't finish while wet mud sits on surfaces, so mud-out comes first. Carpet padding that soaked in muddy water, and drywall or insulation that stayed wet, usually still need to come out. If your basement or crawl space took water, pump it out, get carpet pad and cardboard off the floor the same day, and run a dehumidifier hard for several days — not hours. One more valley-specific note: the ground here was already saturated from July's storms, so if water found a way in this time, it likely will again — once things are dry, look at where it entered (a low vent, a doorway, a foundation crack) before the next round of rain. A week later, trust your nose: a sour or musty smell means moisture is still trapped somewhere, and that's usually a bounded fix, not a whole-house job. Our cost guide shows what fair prices look like.

Renters: a West Virginia note

If you rent, two things are true at once. Your landlord is generally responsible for keeping the home habitable — West Virginia law (W. Va. Code § 37-6-30) requires landlords to deliver and maintain rental property in a fit and habitable condition, so water intrusion and the dampness that follows are generally the owner's to fix once you give notice. And your own belongings are generally your responsibility (renters insurance may help). Send that notice in writing today, keep the dated photos from step 4, and see our renters guide for what to say and how the process works.

Emergency, or can you slow down? An honest triage

🔴

Call a pro now

Standing water you can't remove, sewage backup, a large soaked area, or water inside walls, ceilings, or a flooded finished basement. Acting fast is almost always cheaper than the mold that follows.

🟡

Dry it, then reassess

Water got in but you've removed it and drying is underway. Watch for musty smells or stains over the next week, and test only if a question remains.

🟢

Handle it yourself

A small amount of water, fully dried within a day, on hard non-porous surfaces. Keep it dry and ventilated — you very likely don't need to spend a dime.

A note on storm-chasing contractors

After a widely reported flood, door-knockers and urgent phone pitches follow. Some are fine; some are not. The honest rule: no reputable company needs you to sign tonight. Get the water out first, take your photos, and compare at least two quotes for anything over a few hundred dollars. Our cost guide shows what mold and water-damage work typically costs, so you can spot a scare-quote when you see one.

Will insurance — or FEMA — cover it?

It depends on how the water got in. Standard homeowners policies often exclude rising surface water — that's typically a separate flood policy, like NFIP, and many Kanawha Valley homes outside the mapped floodplain don't carry one, so don't assume you have coverage either way. Sewer or drain backup usually needs its own rider — worth checking, since storm drains and small creeks backed up in exactly this kind of rain. On government help: West Virginia received a federal major disaster declaration on August 3 for July's storms, and the state has said that emergency footing remains in effect — but whether this August event's damage in your county qualifies for individual assistance hadn't been decided when this page was written. Check DisasterAssistance.gov for the current status for your county, and report your damage to your county emergency management office either way — those reports are how counties make the case for assistance. The dated photos in step 4 make every claim easier. Your insurer makes the coverage call, not us — call them early and ask directly.

Frequently asked

My house took on water in the flash flooding. How long do I have before mold starts?

Mold can begin growing on damp materials within about 24–48 hours. The priority right now is drying — get standing water out, move air across wet surfaces, and run a dehumidifier. Speed matters more than testing in the first two days.

The flood left mud and silt in my basement. Is that different from clean water?

Yes. Runoff that came down a hillside or up from a creek carries silt, and often whatever was on the roads and in the storm drains. Shovel and hose out the mud first — drying can't finish while wet silt sits on surfaces. Hard surfaces can be cleaned and dried; carpet padding and drywall that soaked in muddy water usually need to come out. Wear gloves and wash up after handling anything the floodwater touched.

I rent in West Virginia. Who is responsible for flood cleanup and mold?

West Virginia law (W. Va. Code § 37-6-30) requires landlords to deliver and maintain rental property in a fit and habitable condition, so water intrusion and the dampness that follows are generally the owner's responsibility once you give notice. Notify your landlord in writing right away, keep dated photos, and keep copies of everything. Your own belongings are typically your responsibility — renters insurance may help.
