Water Damage After a Hurricane: Cleanup Priority List

Last updated October 25, 2026

The short answer

Safety First

Before you touch anything, confirm the power is off at the main breaker if water may have reached outlets or wiring. If you smell gas, leave the house and call the gas company from outside. Wear rubber boots and gloves, and avoid any standing water that might be electrified.

Check for structural damage, like sagging ceilings or shifted walls, before you walk through rooms. If you feel unwell from fumes or stress, step outside and see a doctor if symptoms persist. Keep children and pets away from flooded areas until you have cleared the space.

Remove Standing Water

Use a wet/dry vacuum, buckets, or a portable pump to remove as much water as possible. The faster you get rid of standing water, the less time it has to soak into walls and floors. Open doors and windows to let air move through, and use fans to help drying.

If the water came from a storm surge, it may contain sewage and chemicals, so treat it as contaminated. Do not run your central air conditioning until you have cleared the water and dried the area, as it can spread moisture. Focus on the lowest level first, like a crawlspace, if that is where water collects.

  • Turn off power at the breaker before entering flooded rooms.
  • Wear rubber boots, gloves, and a mask for protection.
  • Use a pump or wet/dry vacuum to remove standing water.
  • Open windows and doors for cross-ventilation.
  • Discard anything that cannot be cleaned and dried fully.

Dry Out the Structure

After the water is gone, the work is not over. Remove wet carpet, padding, and soaked drywall, especially if water wicked up the walls. Cut drywall at least 12 inches above the water line to allow the wall cavity to dry. Pull out insulation that holds moisture.

Run dehumidifiers and high-velocity fans to pull moisture from wood and concrete. In humid climates, drying can take longer, so keep air moving. Do not rush to rebuild until materials are completely dry, which may take several days to weeks.

Sort and Salvage Belongings

Separate items into three piles: keep, toss, and clean. Porous things like mattresses, pillows, and upholstered furniture often cannot be saved after floodwater. Hard surfaces like glass, metal, and plastic can be washed with a mild detergent and clean water.

Photograph damaged items and the condition of your home before you throw anything away, as your insurance company may need documentation. Check your policy to understand what is covered. Policies vary, and your insurer decides what is covered. For important papers, try to dry them slowly and keep them for reference.

  • Discard porous items like mattresses and pillows.
  • Clean hard surfaces with detergent and water.
  • Document damage with photos for insurance claims.
  • Dry important papers slowly to avoid sticking.
  • Set aside items that need professional cleaning.

Prevent Mold Growth

Mold can start growing within 24 to 48 hours in warm, damp conditions. After drying, clean all surfaces with a solution of one part bleach to ten parts water, or use a mold cleaner. Do not paint or seal surfaces until they are fully dry and clean.

Watch for musty odors and discoloration on wood or drywall. If you see mold spreading beyond a small area, a mold professional can help assess the situation. Keep the area dry and ventilated, and consider a dehumidifier for weeks after the initial cleanup.

Frequently asked questions

How long do I have to start cleanup after a hurricane?

Start as soon as it is safe, ideally within 24 to 48 hours. The longer water sits, the more damage it causes to wood, drywall, and belongings. Mold can begin growing quickly, so act fast to dry out your home.

Can I clean up floodwater myself?

You can remove standing water and dry small areas yourself if you are safe. For large floods, especially with contaminated water, you may need professional help. Water damage pros have equipment to dry structures thoroughly and can handle hazardous materials.

What should I do with wet drywall?

Cut and remove drywall that got wet, especially if it is soaked or shows a water line. Leave the wall cavity open to dry, and remove wet insulation. Do not replace drywall until the wood framing is completely dry to prevent mold.
