How to Get Rid of Water Damage Inside a House (and Stop Mold) in 2026

Updated October 2026. For homeowners dealing with a leak, a burst pipe or a flooded room, and for sellers wondering what to disclose afterward.

How do you get rid of water damage inside a house? Make it safe, stop the water, then dry everything fast. As of October 2026, the EPA says wet materials dried within 24 to 48 hours usually won’t grow mold. After that, remove what can’t be saved, clean and disinfect, check for hidden mold, and repair. Mold patches larger than about 10 square feet are usually a job for a professional.

Water damage feels urgent because it is. Here’s the order we’d follow, from the first minute to the day you sell.

What should you do first after water damage?

Safety comes before the cleanup. If water is near outlets, cords or the electrical panel, turn off power to that area at the breaker, but only if you can reach the panel without standing in water. If you can’t, call the utility or an electrician.

Then stop the water. Shut the main water valve if a pipe burst, and find the source of any slow leak. After a big flood, turn off the gas too, and leave if you smell it.

Move with care. Murky water can hide sharp objects, and wet floors are slippery. Wear waterproof boots and gloves. Throw out food that touched floodwater. If the water came from sewage or a flood, treat it as contaminated and keep children and pets away.

Take photos and video of everything before you move it. Your insurer will want them, and a dated record helps if you sell later.

How fast do you need to dry a wet house?

Fast. The EPA’s guide to mold and moisture says that if wet or damp materials are dried 24 to 48 hours after a leak or spill, in most cases mold will not grow. That’s the clock you’re racing.

• Pull out rugs, cushions, boxes and furniture that can be moved.
• Mop or wet-vac standing water.
• Run fans and dehumidifiers day and night; open windows if the air outside is drier.
• Pull baseboards and drill small holes low in wet drywall so the cavity can dry.
• Rent industrial fans or call a restoration company for anything bigger than one room.

Some things don’t come back. Soaked carpet pad, wet insulation and drywall that has wicked water up from the floor usually need to go. Our tips and tricks for dealing with water damage in your home cover more of the cleanup.

How do you check for and remove mold after a leak?

Look and smell. Mold shows up as spots or fuzz in many colors, and a musty odor means it may be growing where you can’t see it, under floors or inside walls. Check behind furniture, under sinks and in closets near the leak.

Size decides who cleans it. The EPA mold cleanup page says a moldy area under about 10 square feet, roughly 3 feet by 3 feet, can usually be handled yourself. A lot of water damage, mold over that size, sewage water, or mold in the HVAC system calls for a professional. The EPA also warns not to run an HVAC system you suspect is contaminated.

The folks at Mold Inspection Company note that mold can be found anywhere in a home and can cause serious allergic reactions, so they recommend acting right away. If anyone in the house has asthma or a weak immune system, get a pro in early.

For small jobs on hard surfaces, the EPA says to scrub mold off with detergent and water, then dry completely. Many people use a vinegar and water mix for light cleaning. The EPA warns never to mix chlorine bleach with cleaners that contain ammonia, because the fumes are toxic. Porous materials with mold, like ceiling tiles or carpet, usually have to be thrown out.

Prevention is cheaper than removal. Our guide to preventing mold growth in your home covers humidity, ventilation and leaks. In bathrooms, where mold loves to start, see how to make your bathroom a room of health and cleanliness.

Do you need to disinfect after water damage?

Yes, if the water was dirty. Floodwater and sewage carry bacteria. Clean hard surfaces first, then disinfect them, and wash or throw out anything soft that touched the water. Follow the label on any disinfectant, wear gloves and keep the room ventilated.

Clean water from a supply line is less risky, but disinfect anyway if it sat for more than a day or two.

How do you repair a house after water damage?

Fix the cause before you fix the finish. A new ceiling under a roof that still leaks is wasted money. If the water came from above, our guide on how to calculate the cost of a roof restoration helps you budget.

The usual repairs are drywall, flooring, baseboards, doors and paint, plus any electrical or plumbing that got wet. Ask your city or county whether the work needs a permit; electrical and structural work usually does. Keep every invoice and permit.

After a real flood, rebuild smarter: water-resistant flooring, raised outlets, a sump pump. Our 7 tips to remodel your home after a flood go room by room.

Don’t skip insurance steps. Call your insurer early, document everything, and get approval before you throw out big items or start major work. Standard homeowners policies usually exclude flood, which needs separate coverage.

Do you have to disclose water damage when you sell?

In most cases, yes, if you know about it. State seller disclosure rules ask about leaks, flooding, mold and repairs. Being upfront protects you: hidden water damage is a common reason for disputes after closing.

Florida is specific. Under Florida Statutes section 689.302, a seller of residential property must give the buyer a flood disclosure at or before the time the sales contract is signed. It asks whether you know of flooding that damaged the home while you owned it, whether you filed a flood insurance claim, and whether you got federal help such as FEMA aid.

Repaired damage is easier to sell than hidden damage. Gather invoices, permits, the mold clearance report if you had one, and insurance paperwork. Our list of documents needed to sell your home shows where they fit, and 7 warning signs your home needs repairs helps you spot what a buyer’s inspector will find.
