Flood damage: stay safe, clean up, and find the money to rebuild
This hub covers outside water that floods your home: safety, cleanup, mold, insurance, FEMA aid and costs. The rule that matters most: return only when authorities say it is safe, and stay out of floodwater, which can carry sewage and hidden debris (Ready.gov, EPA). Then photograph everything before cleanup. Most homeowners policies do not cover flood, so check for a separate flood policy first (FloodSmart).

Is it safe to go back in?
Not until officials say so. Ready.gov advises returning home only when authorities say it is safe, avoiding floodwater, and never touching electrical equipment that is wet or while you are standing in water. Run generators only outdoors and away from windows. EPA warns that floodwater may carry raw sewage and other hazardous substances, so treat everything it touched as contaminated. Our flood emergency page puts these steps in order for the first 48 hours.
How does flood damage usually unfold?
A flood is a contamination problem as much as a water problem. Water from outside picks up soil, fuel and sewage on the way in, then soaks walls, floors and furniture from the bottom up. Once the water drops, the clock starts on mold. EPA’s flooding guidance says to remove and discard anything that has been wet for more than 24–48 hours because of mold risk. That is why the first week after a flood is about getting wet material out, not saving it. Read mold after a flood before you decide what stays.
Document before you clean
Take photos and video of every room, the waterline on the walls, and damaged belongings before you move them. Write down makes, models and serial numbers of appliances. FloodSmart, the federal flood insurance site, also tells policyholders to keep samples of damaged items like carpet and curtains until the adjuster has seen them. Then begin removing wet material. Our flood cleanup guide covers what to tear out, what to keep, and the protective gear to wear.
Who pays: flood insurance, homeowners insurance, or FEMA?
The order matters. FloodSmart says most homeowners and renters insurance does not cover flood damage. Flood coverage usually comes from a separate policy through the National Flood Insurance Program or a private insurer, and new NFIP coverage generally takes effect 30 days after purchase. If you have a flood policy, report the loss to that insurer as soon as you can.
FEMA aid comes after insurance, not instead of it. FEMA says it cannot provide assistance for losses covered by insurance, and you must file a claim with your insurer first if you have one. FEMA aid is also only available in areas with a federal disaster declaration. Our FEMA assistance guide explains the steps. Ask your insurer, your state insurance department, or a licensed public adjuster how this applies to your policy.
What does flood cleanup cost?
Costs depend on how deep the water got, how long it sat, and how much has to come out. Floodwater is usually graded as the most contaminated category, which raises the price compared with a clean-water leak. Our water damage restoration cost guide collects current published ranges, and water damage categories and classes explains how contamination drives the estimate.
Hiring help after a flood
Big floods bring out-of-town contractors and some outright scams. Before you sign or pay a deposit, read restoration scam red flags and work through the questions to ask a restoration company. Get every price and scope in writing.
