What to Do After a Flood: First 24 Hours
A flood can happen suddenly, leaving you with urgent decisions to make while your property is still at risk. Understanding what to do after a flood—especially in those critical first 24 hours—can make a meaningful difference in recovery outcomes. This guide walks you through the essential steps to take when water damage strikes, from safety priorities to documentation and professional help.
Safety First: Protect Yourself and Others
Before addressing any property damage, your immediate priority is personal safety. If floodwaters are still rising or if you're unsure about electrical hazards—such as live wires in standing water—leave the property and move to higher ground. Floodwater often contains contaminants and poses drowning risks, even in shallow depths. Never attempt to walk or drive through moving water, as currents can be deceptively powerful and sweep vehicles or people away.
Once you're in a safe location, do not return until local authorities confirm it is safe to do so. If your home has power, consider turning off the main electrical breaker if you can do so safely from outside the flooded area. Gas leaks may also be present after severe flooding. If you smell gas, leave immediately and contact your utility company from a safe distance. Document any visible damage by taking photos or videos from outside the property if possible, as these images will be valuable for your insurance claim and for any professional assessment later.
Document Damage and Contact Your Insurance Company
As soon as it is safe, document the extent of the flooding and water damage throughout your home. Take photos and videos of affected rooms, damaged belongings, and waterlines on walls—capture wide shots and close-ups. Write down the date, time, and any details about how the flooding occurred. This documentation is essential for your insurance claim and helps professionals understand what happened. Create a list of damaged items, including approximate purchase dates and values when possible. Even if you're not sure whether damage is covered, report it to your insurance company promptly; delays in reporting can complicate claims.
Contact your insurance agent or claims adjuster within the first 24 hours if you can. Have your policy number ready and be prepared to describe the damage. Ask about immediate coverage, temporary shelter assistance if your home is uninhabitable, and any required next steps. Your insurer may have preferred contractors or networks, but you typically retain the right to choose your own qualified professionals for water removal and restoration. Keep detailed records of all communications, including dates, names, and claim reference numbers.
Begin Water Removal and Prevent Further Damage
Standing water in your home will cause ongoing damage if left untouched, promoting structural deterioration and other problems. Water removal should begin as soon as safely possible. In many cases, property owners benefit from connecting with local water damage restoration providers who have equipment and expertise to extract water quickly and assess hidden moisture. These professionals can often respond within hours and understand local conditions and building codes relevant to your area.
While you wait for professional help, open windows if weather permits and outdoor air is dry, to encourage air circulation. Do not use household fans to move air around flooded spaces, as this can spread moisture unevenly. If you have access to the breaker panel and feel safe doing so, consider turning off appliances in flood-affected areas to reduce electrical risk. Do not enter standing water yourself or attempt to use household pumps or wet-vacs on large volumes of water—professional-grade equipment is designed for this work. Move undamaged items to dry areas if you can do so safely. The first 24 hours are critical; the faster water is removed and drying begins, the better the potential for limiting secondary damage.
