What Do I Do in the First Hour After Flooding?
Last updated October 25, 2026
The short answer
Ensure Personal Safety First
Your first priority is keeping yourself and your family safe. Do not enter standing water if you suspect any electrical hazard, such as submerged outlets or appliances. If the main electrical panel is in a dry area, turn off the power to the flooded zone. Evacuate the area and move to a secure, dry location to assess the situation without immediate risk.
Wear protective gear like rubber boots and gloves if you must walk through the water. Be aware that floodwater can hide sharp objects or cause slips on slick floors. If the flooding is from a sewage backup or outside source, assume the water is contaminated. Keep children and pets away from the affected area to prevent accidental exposure or injury.
Stop the Water Source
If the flooding is from a broken pipe or appliance, locate your main water shutoff valve and turn it off. This valve is often found where the water line enters your home, such as in a garage, utility closet, or near the water heater. Stopping the flow prevents additional water from entering your home and worsening the damage. Knowing how to operate this basic control is a key part of home preparedness.
For flooding from heavy rain or an external source, you may not be able to stop the water. In these cases, focus on moving valuables and mitigating damage instead. If the source is a failed appliance like a water heater, you can shut off its individual supply valve. Knowing how to operate these basic controls is a key part of home preparedness for any water emergency.
Document the Damage Thoroughly
Use your phone or camera to take clear photos and videos of all affected areas and items. Capture water levels, damaged belongings, and the source if visible. This visual evidence is crucial for your insurance claim and for water damage pros to understand the scope. Take pictures from multiple angles and include wide shots of the room along with close-ups of specific damage.
Write down a list of damaged items as best you can, noting their approximate age and value. Do not throw anything away until you have documented it, as your insurer may need to see it. Keep this documentation organized and safe. This step helps create a clear record of what happened during the initial stages of the flooding incident.
- Photograph standing water levels and the source.
- Video pan across entire rooms showing all damage.
- Take close-up shots of ruined flooring, drywall, or furniture.
- Document serial numbers and models of damaged electronics.
- Include photos of any personal belongings that are affected.
- Save all photos and videos in a secure digital folder.
Contact Your Insurance Company
Contact your insurance company's claims department as soon as possible after ensuring safety. Report the flooding and provide the basic facts, such as the cause and extent you have observed. They can guide you on the next steps for filing a claim. Policies vary, and your insurer decides what is covered.
Ask your insurer about your policy's coverage details for water damage and any required procedures. They might send an adjuster to inspect the property. Keep a record of all conversations, including the date, time, and the name of the representative you speak with. Do not begin major repairs or discarding items until you understand your insurer's process, but you can start removing water as discussed below.
Begin Initial Water Removal
If it is safe and you have the equipment, start removing standing water with a wet-dry vacuum, mops, or towels. This can help slow secondary damage like swelling wood or mold growth. Move saturated rugs and furniture to a dry area if possible, but be careful not to injure yourself lifting heavy, waterlogged items. Focus on removing water, not on repairs, in this first hour.
- Use a wet-dry vacuum for large volumes of water.
- Mop and towel-dry hard surface floors.
- Move lightweight, soaked items like area rugs outside.
- Prop up wet furniture cushions for better air circulation.
- Use fans to increase airflow across damp surfaces.
- Place wood blocks or foil under furniture on wet carpet.

Should I try to save my electronics?
Do not touch electronics if they are wet or near standing water due to shock risk. Once power is off and the area is dry, a qualified appliance repair professional may assess them. Corrosion can occur quickly, so professional evaluation is often needed to determine if repair is possible.
What if the flooding is from a storm?
For storm or floodwater, safety is paramount as the water is often contaminated. Avoid contact and do not attempt to stop the water. Document the damage from a safe distance. This type of flooding typically requires extensive cleanup by local water damage pros due to health risks.
How quickly should I call for professional help?
Contact local water damage pros as soon as you have addressed safety and documented the damage. Acting quickly helps limit structural damage and mold growth, which can begin within 24 to 48 hours in a warm, humid climate.
