What Should I Do First After My Home Floods?

Last updated October 25, 2026

The short answer

Ensure Safety and Stop the Water

Your immediate priority is your own safety. Do not enter standing water if the electricity is on, as it poses a serious electrocution risk. If you can safely reach your main electrical panel, turn off the power to the flooded area. Next, locate the source of the water. If it is from a broken pipe, find the main shutoff valve and turn it off to prevent more water from entering.

For a flood from weather or a sewer backup, you may not be able to stop the water. In that case, your focus shifts to protecting your home's contents and structure. Move what you can to a higher, dry location, but do not risk your safety. Know the location of your home's main shutoff valve ahead of time, as this is helpful during an emergency.

Call for Professional Help

Once the immediate danger is managed, contact local water damage pros. They have the equipment and training to properly dry your home, which is critical to prevent mold and structural decay. A delayed response allows water to soak deeper into materials. They can assess the damage and develop a plan for drying and repair.

This is not a DIY project. Home drying requires industrial air movers, dehumidifiers, and moisture meters to ensure walls and floors are dry inside. In humid climates, indoor humidity can slow drying and encourage mold growth. The pros monitor the process to meet drying standards, which helps protect your home's structure and your health.

  • They extract standing water quickly with truck-mounted pumps.
  • They set up air movers to circulate air across wet surfaces.
  • They use dehumidifiers to pull moisture from the air and building materials.
  • They monitor moisture levels in walls and subfloors with specialized meters.
  • They may remove baseboards or drill holes to allow walls to dry.
  • They can identify hidden moisture pockets behind cabinets or under flooring.

Document Everything for Insurance

Take detailed photographs and videos of all damage before any cleanup begins. Capture water levels, damaged possessions, and the overall condition of affected rooms. This visual evidence is crucial when you file a claim with your insurance company. Make a written list of damaged items, including descriptions, purchase dates if known, and estimated values. Do not throw anything away until an adjuster has seen it.

Contact your insurance company to start the claims process. Be ready to provide your policy number and a basic description of the incident. Policies vary, and your insurer decides what is covered. Keep a record of all conversations, including the names of representatives and the dates you spoke. Save receipts for any temporary repairs or costs you incur, like a hotel stay if you must relocate.

Begin Mitigating Damage

While waiting for the pros, you can take some safe actions to reduce further damage. If it is safe to do so, remove small, saturated items like rugs, curtains, and cushions. Prop up wet furniture cushions and place aluminum foil under furniture legs to prevent staining on carpets. Increase airflow by opening windows if the outdoor air is drier than indoors, but be cautious of letting in more humidity.

Do not use your household vacuum to remove water, as this can damage the appliance and risk electrocution. Avoid turning on ceiling fixtures if the ceiling is sagging from water weight. Do not enter rooms with sagging ceilings. Your goal is to support the pros' work by preventing secondary damage, not to start the major drying process yourself, which requires professional equipment.

Understand the Restoration Process

Professional water damage restoration follows a defined process. It starts with an inspection to map the moisture in your home. The pros then extract water and set up drying equipment. They may need to remove damaged materials like wet drywall or flooring that cannot be salvaged. The drying phase typically takes several days, with ongoing monitoring to ensure all moisture is eliminated.

  • Inspection and damage assessment using moisture meters.
  • Water removal with powerful extraction equipment.
  • Drying and dehumidification with industrial-grade machines.
  • Cleaning and sanitizing of affected areas and belongings.
  • Monitoring of moisture levels until drying goals are met.
  • Repair and reconstruction of damaged structural elements.

Frequently asked questions

How long does it take for mold to grow after a flood?

Mold can begin to grow within 24 to 48 hours in damp conditions. This is why prompt, professional drying is so critical. Lingering moisture inside walls or under floors creates the perfect environment for mold spores, which are always present in the air, to colonize and spread.

Will my homeowners insurance cover flood damage?

It depends on the source of the water. Most standard policies cover sudden, accidental leaks like a burst pipe. Damage from external flooding, like storm surge or ground water, typically requires a separate flood insurance policy. Policies vary, and your insurer decides what is covered.

Can I stay in my home during water damage restoration?

It depends on the extent of the damage. For a small, contained leak, you might stay. For major flooding, you may need to relocate due to safety hazards, noise, and humidity from drying equipment. They can advise based on the specific conditions in your home.
