Immediate Flood Action Checklist

Before diving into the detailed guide, here’s a quick snapshot of what to do immediately after a flood:

• Ensure it is safe to return home.
• Shut off electricity, gas, and water.
• Document all damage with photos and videos.
• Contact your insurance provider immediately.
• Remove water-damaged belongings and begin drying out the home.
• Wear proper personal protective equipment (PPE) at all times.
• Seek professional help for extensive water damage or structural concerns.

What Should I Do If My Home Floods?

Once it is safe to return to your home, your first priority is to assess the extent of the damage. Take photos or videos for documentation, as this will be important for insurance claims. Begin drying out your home quickly to prevent further damage and reduce the risk of mold growth.

1. Ensure it is safe to return: Wait for local authorities to issue an all-clear before heading back. Floodwater can weaken structures and hide hazards.
2. Shut off power, gas, and water: Check the structural integrity before entering. If the floodwater reached electrical outlets, call a licensed electrician.
3. Document all damage: Most standard homeowners’ insurance policies do not cover flood damage, but private flood insurance typically does. Keep records for all expenses and damaged items.
4. Ask for help when needed: Flood cleanup can be physically and emotionally overwhelming. Seek assistance from volunteer organizations, neighbors, friends, or professional contractors specializing in flood restoration.

Tips to Start Cleaning Up After a Flood

Flood recovery is rarely quick, it takes time, patience, and the right approach. Once the immediate danger has passed and it is safe to return, your focus should shift to stabilizing your home and beginning the cleanup process. This includes gathering the proper equipment, ensuring your home is structurally secure, and removing items that have been damaged beyond repair. Taking these steps early not only helps prevent further damage but also makes the restoration process more manageable.

Here are some important tips to keep in mind once you’re ready to begin cleaning up after a flood:

Use Personal Protective Equipment

It is essential to wear proper protective gear while cleaning your home after a flood. Always use rubber boots, gloves, and durable clothing to minimize direct contact with contaminated surfaces. Floodwater often contains hazardous substances such as chemicals, raw sewage, and other dangerous residues that remain even after the water has receded. In addition, they may carry lead-based particles, mold spores, and other harmful contaminants. To protect your lungs, be sure to also wear an N95 mask while working in these conditions.

Remove Everything

To begin drying out your property, the first step is to remove all water-damaged items. Leaving them in place can trap moisture and allow mold spores to spread, worsening the damage. Separate and set aside any belongings that can be salvaged, such as family photos, important documents, or solid wood furniture. However, porous materials like carpet and carpet padding should always be removed and discarded, as they retain moisture and are highly susceptible to mold growth.

Demo Down to the Studs and Concrete Slab

While it may be possible to save certain sections of wood flooring after a flood, in many cases the damaged materials will need to be removed down to the concrete slab and wall studs. Water-damaged drywall should also be demolished, and most homeowners are able to handle this task themselves. As a precaution, cut the drywall at least one foot above the waterline. Although water usually wicks only a few inches above the visible line, it’s better to remove extra material to ensure no hidden moisture remains. Water can also wick into wall studs, but in most cases, solid wood two-by-fours will dry out naturally after a few days.

After removing the appropriate sections of drywall, the insulation behind it must also be cut out and discarded. Avoid yanking insulation from the wall, as this can leave gaps near the top; instead, cut it cleanly for proper removal.

Once you’ve documented the damage and submitted your insurance claim, an adjuster will eventually inspect your property. In the aftermath of large-scale disasters, however, it may take some time before an adjuster is able to visit. To protect your claim, always save a small section of wet drywall as physical evidence of the waterline for the inspection.

Don’t Forget Hidden Spaces

Be sure to thoroughly check drawers, cabinets, and other hidden areas where standing water may collect. Moisture often lingers behind cabinets or at the base of a kitchen island, where damage can go unnoticed. In many cases, cabinets made from solid plywood can be salvaged once they are properly dried. However, you will need to remove the drywall and insulation behind them while leaving the cabinet structure intact. If your cabinets are constructed from pressboard or particleboard, they are far less durable and will likely need to be replaced.

Interior doors may sometimes be saved as well. To dry them out, remove the doors from their hinges and place them outside, laying flat with space between each one to allow air circulation. Positioning fans nearby can speed up the drying process and improve the chances of preserving the doors.

Clean and Disinfect

Use a broom and a shop vac to clean all surfaces thoroughly, removing mud, debris, and standing water. For solid surfaces like studs and concrete slabs, you can rinse them with clean water to help eliminate bacteria and contaminants left behind by floodwater. To further disinfect the area, prepare a bleach solution by mixing half a cup of bleach with one gallon of water. Pour the solution into a pump spray bottle and apply it evenly to affected surfaces to help kill mold, bacteria, and other harmful microorganisms. Always wear protective gloves, goggles, and a mask when handling bleach, and ensure the area is well-ventilated.

Ventilate and Dry the Area

Once you’ve removed debris and thoroughly cleaned your home, use fans to help speed up the drying process. Keep windows and doors open whenever possible to improve air circulation and ventilation. Depending on the severity of the flooding, it can take two to four weeks for your home to fully dry before any rebuilding or restoration work can safely begin. Patience during this stage is essential to prevent mold growth and ensure your home is properly prepared for repairs.

Hire Only Credentialed Contractors

Once you begin the rebuilding process with a professional, it’s important to remain vigilant against scam contractors who may try to take shortcuts or overcharge for their services. Always verify that any contractor you hire is properly licensed and insured. Check references carefully, and if possible, visit previous projects or speak directly with satisfied customers to ensure the quality of their work. Be especially cautious about paying a large deposit upfront, establish clear payment terms and only pay for work that has been completed to your satisfaction.

What actions should I avoid after my home is flooded?

After a flood, there are several important actions you should avoid to protect yourself, your family, and your home:

1. Entering unsafe areas: Avoid going into your home until authorities confirm it is safe. Floodwater can weaken structures, collapse ceilings, or hide electrical hazards.
2. Touching electrical systems or appliances: Never touch electrical outlets, switches, or appliances if they have been submerged. Turn off power at the main breaker before entering.
3. Ignoring protective gear: Avoid working in flooded areas without gloves, boots, and an N95 mask. Floodwater can carry bacteria, mold spores, chemicals, and sewage.
4. Delaying documentation: Don’t start cleanup or disposal before documenting damage with photos and videos. Insurance claims require proof of damage.
5. Using contaminated water: Avoid drinking tap water until authorities confirm it’s safe. Flooding can contaminate water lines with bacteria or chemicals.
6. Ignoring mold prevention: Don’t leave wet materials like carpet, drywall, or insulation in place. Moisture left behind encourages mold growth and can worsen damage.
7. Hiring unverified contractors: Avoid rushing to hire the first contractor who offers services. Always check credentials, references, licenses, and insurance to avoid scams.
8. Mixing cleaning chemicals improperly: Avoid using bleach or other cleaners together with ammonia or other products, as toxic fumes can result.
9. Underestimating structural damage: Don’t attempt major repairs, like removing flooring or walls, if you’re unsure of the building’s integrity, wait for professional guidance.

What Should I Throw Away After a Flood?

Floodwater can carry bacteria, chemicals, and sewage, so it’s better to err on the side of caution. Items that can’t be fully sanitized should be thrown away to prevent mold growth and health hazards.

Porous building materials:

• Drywall and insulation that have absorbed water.
• Particleboard or pressboard cabinetry.
• Ceiling tiles and wallpaper backing.
