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. 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.
Compliant disposal protects your Los Altos, CA property from liability down the line.
Containment barriers go up before cleanup starts, keeping contaminated water isolated from living spaces.
Sewage cleanup follows a strict sequence built around safety, and here's how our Los Altos, CA crews handle it.

Contaminated water is extracted using equipment dedicated to blackwater jobs, kept separate from clean-water equipment.
Crews are trained specifically in biohazard-level cleanup procedures.
Porous materials — carpet, drywall, insulation — that contacted sewage are removed and disposed of per regulatory guidelines.
We apply compliant disinfection products across the full affected area.
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.
Containment barriers and PPE are standard equipment for every dispatch.
A biohazard assessment and written quote come before any extraction starts.
The file doesn't close until pathogen and odor control are confirmed complete.

We use EPA-registered antimicrobial products specifically rated for blackwater contamination.
We don't close the file until air and surface checks pass.
We recommend checking your specific policy, and we'll support the claim with proper documentation either way.
Immediately — the longer contaminated water sits, the further bacteria and odor can spread into surrounding materials.
