Immediate actions
- 1 Ensure the building is structurally safe and turn off main utilities if safe to reach.
- 2 Document all damage thoroughly with photos and video before starting any cleanup.
- 3 Contact your insurance company and local disaster assistance services to report the damage.
- 4 Begin removing standing water and contaminated materials safely while wearing protective gear.
What not to do / warning
Do not enter standing floodwater if electricity is still active, and never run gasoline generators indoors due to the risk of fatal carbon monoxide poisoning.
Discovering flood damage in your home can be overwhelming. Floodwaters carry serious safety risks, including electrical hazards, structural instability, and toxic contamination. Taking prompt, safe, and deliberate steps will protect your health and help speed up recovery.
Emergency Safety Warnings
Never enter a flooded building until local authorities have declared it safe. If you smell gas, hear loud structural creaks, or see downed power lines near water, clear the area and call local emergency services immediately.
What to Do First
- Check for structural stability: Look for sagging ceilings, bulged walls, or foundational cracks before stepping inside.
- Shut off utilities safely: If you can reach your circuit breaker and gas line without walking through standing water, turn them off. If the electrical panel is submerged or wet, do not touch it.
- Document all damage: Take high-resolution photographs and videos of all affected areas, water marks on walls, and damaged belongings before moving or cleaning anything.
- Notify your insurance provider: File your claim as quickly as possible. Ask what temporary emergency repairs are covered under your policy before hiring contractors.
- Start water removal: Use pumps, wet-dry vacuums, or mops to extract standing water if it is safe to use electricity. Wear protective rubber boots, heavy-duty gloves, and an N95 mask to avoid contact with sewage or mold.
What NOT to Do
- Do not walk through standing floodwater if the electrical main is still active or unknown.
- Do not use portable generators indoors, in attached garages, or near open windows, as carbon monoxide buildup is invisible and lethal.
- Do not eat food that has come into contact with floodwater or was stored in an unpowered refrigerator for an extended period.
- Do not turn on electrical appliances or heating systems until they have been inspected by a certified technician.
Preventing Mold Growth
Mold begins developing within 24 to 48 hours of water exposure. Promote continuous air circulation by opening windows if outdoor air is dry. Remove soaked drywall, insulation, carpet, and soft furnishings that cannot be completely dried and disinfected quickly. Run dehumidifiers and fans continuously once power is safely restored.
Focus first on personal safety, document everything for recovery assistance, and proceed carefully with cleanup to restore your home safely.
