What to Do After Basement Flooding
A practical guide to basement flooding safety, documentation, water-source questions, extraction and structural drying.
Treat the water category seriously
- Clean-water losses, grey water and sewage require different controls.
- Avoid contact with contaminated water.
Plan extraction and drying
- Standing water should be removed with suitable equipment.
- Wet finishes may need to be exposed or removed.
- Air movement and dehumidification should be monitored.
Watch for delayed moisture
- Concrete, framing, insulation and wall cavities can retain moisture after the visible water is gone.
