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.
Our Cotati, CA crews suit up in full PPE before entering a contaminated space, no exceptions.

We follow strict biohazard protocol on every Sewage Cleanup call, treating even a small backup with full precaution.
Our Cotati, CA 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.
Sewage cleanup follows a strict sequence built around safety, and here's how our Cotati, CA crews handle it.

Blackwater extraction follows Category 3 protocol from the first pump-down.
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.
Final verification checks confirm the biohazard has been fully addressed.
We ask enough to confirm this is a sewage-related call and prepare accordingly.
Containment barriers and PPE are standard equipment for every dispatch.
We assess contamination scope and provide a written estimate before cleanup begins.
We verify air quality and surface disinfection before signing off on the job.

"Appreciated that they explained exactly what would need to be thrown away and why, rather than just guessing." — Desmond K.
"The smell was completely gone by the time they finished, not just masked with an air freshener." — Alina M.
Blackwater contamination poses real health risk, unlike clean-water leaks, which is why it needs a different protocol.
Porous materials that contacted blackwater usually need to be removed and disposed of, since they can't be fully disinfected.
Compliant, registered products are standard on every sewage job.
Post-cleanup verification confirms the space is safe for reoccupation.
Often yes, especially for sudden sewer backups, though coverage varies by policy — we can help document the loss for your claim.
Sewage should be treated as urgent, since delay increases both health risk and the amount of material that can't be saved.
If your property is in or near Cotati, a crew can typically respond the same day.
