1. Make the area safe
Keep people away from standing water near electrical equipment, sagging ceilings, sewage or other obvious hazards. Use emergency services or the appropriate utility when the situation requires it.
2. Stop the water source
Turn off the leaking fixture, appliance supply or main water valve when you can do so safely. If the source is a roof, sewer or other system, arrange for the appropriate repair.
3. Document what happened
Photos and notes can help establish what was affected and when it was discovered. Keep receipts and records related to cleanup and repairs.
4. Remove water and check moisture
Standing water should be addressed, but visible dryness is not the whole story. Porous materials and concealed assemblies may retain moisture.
5. Decide what needs professional help
Large releases, contaminated water, water inside assemblies or situations involving safety concerns are strong reasons to seek professional restoration assistance.
