Sewage backup is Category 3 blackwater, which means it carries real health risk and requires a completely different protocol than a clean-water leak. This is one water damage situation where calling a trained crew immediately matters more than trying to handle it yourself.
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.
Sanitization on every Sewage Cleanup job meets the EPA-registered standard for Category 3 water.
We document disposal of contaminated materials to keep the process compliant and traceable.
Health and safety drive our containment approach on every sewage call.
