Key points
- Sewage carries bacteria, viruses, and parasites — it’s classified as Category 3 (“black”) water.
- Keep children, pregnant women, older adults, pets, and anyone with a weakened immune system away.
- Porous materials it touched usually can’t be saved.
- Bleach and a shop vac aren’t enough for anything beyond a tiny, contained spill.
Why it’s different from a clean-water leak
Clean supply-line water can often be dried in place. Sewage contaminates whatever it touches, and drying doesn’t remove contamination. See water categories explained.
What usually has to go
- Carpet and carpet pad
- Drywall and insulation below the water line
- Upholstered furniture and mattresses
- Cardboard, paper, and porous stored items
- Particleboard cabinets and furniture
How professional cleanup works
- Sealed containment, negative air where appropriate, and PPE for the crew.
- Removal of sewage and contaminated materials.
- Cleaning and disinfecting remaining surfaces with EPA-registered products.
- Drying the structure with daily moisture readings.
- Repairs once everything is clean and dry.
