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.

Every technician entering a Stratham, NH sewage job wears full PPE — no shortcuts, regardless of how minor the backup looks.
We apply EPA-registered antimicrobial products specifically rated for blackwater contamination.
We document disposal of contaminated materials to keep the process compliant and traceable.
Containment barriers go up before cleanup starts, keeping contaminated water isolated from living spaces.
