A backed-up sewer line or failed septic system doesn't just mean a mess — it means contaminated water carrying bacteria and pathogens that has to be handled under strict containment. A DIY approach to sewage cleanup puts household members at real risk of exposure.
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.
We apply EPA-registered antimicrobial products specifically rated for blackwater contamination.
We document disposal of contaminated materials to keep the process compliant and traceable.
Health and safety drive our containment approach on every sewage call.
Here's the full scope of a Holderness sewage backup response.

Crews are trained specifically in biohazard-level cleanup procedures.
Anything that can't be fully disinfected gets removed and disposed of properly, not reused.
Affected surfaces receive EPA-registered antimicrobial treatment rated for blackwater contamination.
Pathogen control continues until air and surface testing confirm the space is safe.
Air quality sign-off happens before we consider the job complete.
Every sewage call gets routed with full PPE crews from the start.

We assess contamination scope and provide a written estimate before cleanup begins.
The file doesn't close until pathogen and odor control are confirmed complete.

Post-cleanup verification confirms the space is safe for reoccupation.
