What to Do Before the Crew Arrives
Sewage water can reach insulation that will not dry safely in place. Removing affected porous material gives the remaining structure a path to dry.
- Keep everyone upstairs and away from the contaminated stairway.
- Do not walk through water to shut off basement power.
- Stop using household drains until a septic company checks the system.
- Leave wet electrical and utility equipment untouched.
- Photograph the water level from a dry, safe position.
