Sewage backup is classified as Category 3 ("black") water — the most dangerous category, containing bacteria, viruses, and other pathogens. Standard cleanup methods aren't enough: contaminated drywall, carpet, and padding usually have to be removed entirely, and the affected area needs full sanitization. This is not a DIY job.
Tree roots, grease buildup, or municipal sewer overflow push raw sewage back up into basement floor drains, toilets, and tubs.
A clogged toilet or failed wax ring can release contaminated water into bathrooms and adjacent rooms.
When a sump pump fails during heavy rain, the resulting basement flood is often mixed with sewage from the sanitary system.
The affected area is isolated and technicians enter in full protective gear to prevent cross-contamination.
Specialized equipment removes contaminated water and solids.
Porous materials — carpet, padding, drywall below the waterline, contaminated insulation — are removed and disposed of.
Hospital-grade disinfectants and antimicrobials treat every surface. Air scrubbers run for 24–72 hours.
After sanitization, the structure is dried and rebuilt.
