You are finally home after the storm, you step onto the carpet, and it squishes. Water damage is hard because most of it hides: under the floors, behind the drywall, inside the insulation. And it is a race against time, because wet materials need to be dried within a day or two to help prevent mold. This guide covers what to do first, where water hides, the photos to take, what water damage restoration pros do, and how to get bids from verified local pros fast.

First: stay safe

  • Power and water do not mix. If water is near outlets, cords or the electrical panel, do not touch them. Have the power shut off by your utility or an electrician.
  • Smell gas? Leave the house and call the gas company from outside.
  • Floodwater can carry sewage and chemicals. Wear rubber boots and gloves, and keep children and pets away from it.
  • Sagging ceilings and soft floors can give way. Stay out from under and off of them.

Where water hides

WhereWhat to look for
Under floorsCupping wood, lifting vinyl or laminate, a soft or bouncy feel
Behind drywallA water line, bubbling paint, soft spots near the bottom of walls
Carpet padCarpet that looks dry on top but squishes underfoot
CabinetsSwollen cabinet bottoms and toe kicks under sinks and on outside walls
Insulation and ceilingsStains, sagging and a musty smell
Tip: Drywall soaks water up like a sponge, often well above the water line you can see. Restoration pros use moisture meters to find how far it went.

Why the first 24 to 48 hours matter

Federal flood cleanup guidance says wet materials should be dried within 24 to 48 hours to help prevent mold. That is why getting the water out and the drying started quickly matters more than almost anything else. If you cannot get a pro there today, start what you safely can: lift rugs, move furniture off wet floors, open windows if it is dry outside, and run fans and a dehumidifier if the power is safe.

Take photos before anything goes to the curb

Before you throw anything out, photograph it: each room, the water line on the walls, wet floors and carpet, damaged furniture, appliances and belongings, and any model or serial numbers. Short videos walking through each room help too. Keep receipts for fans, dehumidifiers, cleanup supplies and anything you pay for. Then save what matters: move photos, papers and keepsakes somewhere dry and high.

What water damage restoration pros do

  • Inspect and measure: find where the water went with moisture meters and thermal cameras.
  • Extract the water: pumps and truck-mounted or portable extractors.
  • Dry it out: air movers and dehumidifiers, checked every day until readings are dry.
  • Remove what cannot be dried: wet drywall cut out low on the wall, carpet pad, insulation.
  • Clean and treat for mold where it has started.
  • Put it back: new drywall, paint, floors and cabinets, or the pros who do that work.

Clean water, gray water, floodwater

Pros sort water damage by where the water came from. Clean water from a broken supply line is the easiest to dry. Water from a storm leak can pick up dirt on the way in. Floodwater from rising water outside is treated as contaminated, so more materials usually need to be removed. Tell pros where your water came from so the bids cover the right work.

Insurance: what to know

Call your insurance company soon and ask what they need from you. Coverage depends on your policy and on where the water came from: flooding from rising water is usually covered by a separate flood policy, not standard homeowners insurance, while rain coming through a storm-damaged roof may be handled differently. Your photos, receipts and a written scope from your restoration pro help everyone see the same damage.

What to put in your post

  • Where the water came from: roof leak, rising water, a pipe
  • Which rooms and floors got wet, and roughly how high the water was
  • When it happened, and whether anything is drying yet
  • Photos of each room and the water line
  • Whether you also need a roof tarp, drywall, flooring or junk removal

Questions to ask a restoration pro

  • How will you find all the wet areas, and will you share the moisture readings?
  • What has to be removed, and what can be dried in place?
  • How long will the equipment run, and how often will you check it?
  • Do you also rebuild, or should I post that separately?
  • Do you carry insurance, and any license my state requires for mold work?

What does a water damage restoration company do?

They find where the water went with moisture meters, pump and extract standing water, dry the home with air movers and dehumidifiers, remove materials that cannot be dried such as wet drywall, carpet pad or insulation, treat and remove mold, and then put the rooms back together or work with the pros who do.

How soon does mold grow after water damage?

Federal flood cleanup guidance says wet materials should be dried within 24 to 48 hours to help prevent mold. It is a guideline, not a guarantee, so the sooner the drying starts, the better.

Do I have to remove wet drywall?

Not always. Drywall that was soaked by floodwater, or that stays wet for days, is usually cut out low on the wall and replaced. A restoration pro measures the moisture behind it and tells you what can be dried in place.

Can my carpet be saved?

Sometimes, if it was clean water and it is dried quickly. Carpet and pad soaked by floodwater are usually removed. Ask your restoration pro what kind of water it was and what can be saved.

How long does drying take?

Often several days with air movers and dehumidifiers running, depending on how much water there was and what got wet. Pros check moisture readings each day until the materials are dry.

Does insurance cover water damage after a storm?

It depends on your policy and where the water came from. Flooding from rising water is usually covered by a separate flood policy, not standard homeowners insurance, while rain coming through a storm-damaged roof may be handled differently. Call your insurance company and ask what they need from you.

Is it safe to stay in the house?

Only if the power, gas and structure are safe and the water is not from sewage or floodwater spreading through living areas. If in doubt, ask your utility company and a pro to check before you stay.
