The short answer

Safety First Before You Touch Anything

Wait for local authorities to confirm the area is safe before you enter your home. Floodwater can hide downed power lines, sharp metal, and sewage. If you smell gas or hear a hissing sound, leave the building and contact the gas utility from outside. Turn off the main electrical breaker only if the panel is dry and you can reach it without standing in water.

Wear rubber boots, waterproof gloves, and an N95 mask while you work. Floodwater often contains bacteria, chemicals, and debris that can make you sick. Wash your hands with soap and clean water after touching anything. If you feel unwell, see a doctor. Keep a first aid kit handy for minor cuts and scrapes.

Document Damage for Your Insurance Claim

Before moving anything, take photos and videos of every room, including the water line on walls and furniture. List damaged items with their approximate age and value. This record helps your insurance company understand what was lost. Policies vary, and your insurer decides what is covered. Keep receipts for any supplies you buy for cleanup.

Do not throw away damaged items until you have documented them. If you must discard something for safety, photograph it first and note where it was. Store all records in a dry place, like a sealed plastic bag or a waterproof container. This paperwork makes the claims process smoother, though coverage depends on your policy.

Remove Water and Wet Belongings

Use a pump, wet vacuum, or buckets to remove standing water from your home. Work from the highest point down, and open windows and doors for airflow. Remove soaked carpets, rugs, furniture, and mattresses. These items hold moisture and can grow mold within a day or two. Place them outside to dry or dispose of them if they are heavily contaminated.

Pull up wet drywall and insulation up to at least 12 inches above the water line. Cut drywall with a utility knife and remove it in sections. Save a piece of the watermarked drywall for your insurance records. Dispose of porous items like pillows, stuffed animals, and cardboard boxes that cannot be cleaned properly.

  • Wear gloves and a mask when handling wet materials
  • Use a flashlight to check dark corners and closets
  • Set aside items you want to try to save
  • Keep a log of everything you remove
  • Take breaks to avoid exhaustion and heat stress
  • Never operate electrical equipment near standing water

Clean and Disinfect Surfaces

After removing water, scrub hard surfaces like walls, floors, and countertops with a detergent and water solution. Then apply a disinfectant to kill bacteria and mold spores. Use a mixture of one cup of bleach per gallon of water for non-porous surfaces, but never mix bleach with ammonia. Rinse thoroughly and let surfaces dry completely.

Pay extra attention to areas where floodwater touched food preparation surfaces, like kitchen counters and sinks. If you have a flooded basement, clean the walls and floor with the same method. For sewage or wastewater contamination, the cleaning process is more involved and may require professional help. See a doctor if you develop a cough, skin rash, or other symptoms after cleaning.

Dry Out Your Home Thoroughly

Drying a home takes time, not just a few hours. Use fans, dehumidifiers, and open windows to circulate air. Aim for low humidity and good airflow for at least several days. Check hidden spaces like behind walls, under floors, and inside cabinets for moisture. Keep a dehumidifier running in damp areas to speed up the process.

Monitor the drying progress by feeling materials for dampness and looking for new stains or odors. Mold can start growing within 24 to 48 hours, so act quickly. If the water was deep or the structure is soaked, the pros use industrial drying equipment to reach trapped moisture. Consider contacting local water damage pros for a thorough assessment and cleanup.

  • Run dehumidifiers and fans continuously for several days
  • Open windows when outdoor humidity is lower than indoor
  • Check behind appliances and under cabinets for hidden moisture
  • Use moisture meters if you have them to test walls and floors
  • Replace air filters in your HVAC system after cleanup
  • Watch for musty smells, which signal hidden dampness

Water damage does not wait

Every hour counts once water gets into floors and walls. One call starts the response.

Frequently asked questions

How long should I wait before entering my home after a flood?

Wait until local officials say it is safe. Floodwater may hide dangers like downed power lines, gas leaks, and unstable structures. If you have any doubt, wait longer or ask a building inspector to check the structure first. Your safety matters more than saving belongings.

Can I clean up floodwater myself, or should I hire a professional?

You can handle minor cleanup if the water is clean and the area is small. But if the water came from sewage, contains chemicals, or soaked deep into walls and floors, the pros have the right equipment and training. They also know how to dry structures fully to prevent mold. For safety, call the pros for major flooding.

What should I throw away after a flood?

Throw away porous items that soaked up floodwater, like carpets, mattresses, pillows, upholstered furniture, and cardboard boxes. Also discard food, medicine, and cosmetics that touched floodwater. Hard surfaces like glass, metal, and plastic can be cleaned and disinfected. When in doubt, throw it out to avoid health risks.
