Sewage backup — get it cleaned safely
Sewage (“black water”) carries bacteria and viruses. It is not a mop-and-bucket job — it needs professional containment, sanitizing, and disposal. Here’s what to know and who to call.
Step by step
- 1
Keep people and pets away
Evacuate the affected area; sewage is a serious health hazard, especially for kids, elderly, and immunocompromised people.
- 2
Don’t use household tools
A home vacuum or fans can spread contamination. This category requires professional-grade equipment.
- 3
Call a certified pro
IICRC-certified crews contain, extract, remove porous materials, and sanitize. Document everything for insurance first.

Is sewage cleanup covered by insurance?+
Sewer/drain backup is often covered only if you carry a sewer-backup endorsement — check your policy. The cleanup itself is the most expensive category ($7–$15/sq ft).
Can I clean sewage myself?+
No — Category-3 black water is a biohazard requiring professional decontamination. DIY risks serious illness and leaves contamination behind.
