What to Do in the First Hour After Your Home Floods
Last updated October 25, 2026
The short answer
Prioritize Safety First
Your safety comes before anything else. If water has reached electrical outlets or appliances, do not touch anything. Turn off the main power breaker only if you can do so without stepping into water. If you're unsure, wait for an electrician.
Wear rubber boots and gloves if you must enter flooded areas. Floodwater can hide sharp objects, chemicals, or sewage. Avoid contact with your skin. If you feel unwell or notice a gas smell, leave the house and call the gas company from outside.
Stop the Water Source
If the flood is from a burst pipe or appliance leak, shut off the main water valve to stop the flow. Locate the valve now, before an emergency, so you know where it is. In hot, humid climates, keep the valve location written down near your main entrance.
For natural flooding, like heavy rain or a rising river, you cannot stop the source. Focus on moving items to higher floors or on top of furniture. Move electronics, important documents, and sentimental items to safety.
- Turn off the electricity at the breaker if safe
- Shut off the main water valve for pipe leaks
- Avoid standing water and wear protective gear
- Move valuables to higher ground
- Document damage with photos and video
- Call your insurance company to report the flood
Protect Belongings and Property
Quick action can save your belongings. Lift furniture onto blocks or bricks to keep it out of the water. Remove rugs and curtains if they are wet, and hang them outside to dry. Move paintings and books to a dry area.
Do not throw away damaged items yet. Your insurance company may need to see them. Take photos of everything, including the water level in each room. This documentation helps with your claim. Policies vary, and your insurer decides what is covered.
Document the Damage Thoroughly
Take clear photos and videos of the flooded rooms, the water level, and any damaged items. Capture the brand and model of appliances if possible. This record is essential for your insurance claim and for the pros who will help with cleanup.
Write down the time the flood started and when you first noticed it. Note the water source and whether it was clean or contaminated. This information helps the pros assess the situation and decide the right approach for drying and restoration.
Begin Drying and Ventilation
Open windows and doors to let air circulate, if weather permits. Use fans to move air across wet surfaces. Remove standing water with a pump or wet-dry vacuum, but only if it's safe to do so. The longer water sits, the more damage it causes.
If the flood is from clean water, you can start drying right away. For contaminated water, avoid spreading it. Turn on your HVAC system only if it's safe and the ducts are dry. For major flooding, the pros will handle water extraction and drying with industrial equipment.
- Open windows and doors for ventilation
- Use fans to circulate air
- Remove standing water with a pump or wet-dry vacuum
- Avoid turning on HVAC if ducts are wet
- Separate wet items to prevent mold growth

Should I turn off the electricity if a lower level is flooded?
Only if you can reach the breaker without stepping into water. If the breaker is in a dry area, turn it off. If not, wait for an electrician. Never touch electrical panels while standing in water.
How do I know if the floodwater is contaminated?
If the flood is from a sewer backup, river overflow, or agricultural runoff, assume it's contaminated. Signs include a foul odor or dark color. Treat all floodwater as potentially unsafe. Wear protective gear and avoid skin contact.
Can I start throwing away wet carpet and drywall?
Wait until you've documented the damage and your insurance company has been notified. Some policies require you to preserve damaged items for inspection. If you must remove them, take photos first and keep a sample of the material.
