Sewage backup is Category 3 blackwater, which means it carries real health risk and requires a completely different protocol than a clean-water leak. Attempting to clean up blackwater without proper protective gear is a genuine health hazard, not just an inconvenience.
Containment goes up immediately to keep contaminated water from spreading to unaffected areas of the property.

We follow strict biohazard protocol on every Sewage Cleanup call, treating even a small backup with full precaution.
Our Seattle, WA disinfection process uses compliant, registered products rather than generic household cleaner.
Porous materials that contacted blackwater are disposed of according to regulatory guidelines, not just thrown in a regular dumpster.
Health and safety drive our containment approach on every sewage call.
