If your home has flooded, the first thing you should do is stop any electrical or gas leaks. Do not attempt to use electricity or gas until it has been confirmed by a professional.
Next, turn off all utilities and appliances to prevent further damage. Check with your utility companies to see if they have set up temporary facilities to collect and dispose of wastewater, sewage, and other hazardous materials. This may include water treatment plants, sewage overflows, or storm drains that are being repaired.
Take photos and videos of your property damage, including any flooding-related issues such as standing water, damaged walls, and structural damage. This will help insurance companies assess the extent of the damage if you decide to file a claim.
Be cautious when walking through flooded areas until they have been inspected by professionals. Avoid using electrical appliances or attempting to repair electrical systems, as this can lead to further damage or injury. If you are unsure about the safety of a particular area, it is best to err on the side of caution and avoid it.
If your home has been severely damaged by flooding, consider hiring a professional mold remediation company to assess and clean the affected areas. They can also help with removal of hazardous materials such as lead paint, asbestos, or contaminated soil.
