You flushed, and the shower drain in the basement started gurgling. Minutes later, raw sewage was coming up through the floor drain and both toilets. This is Category 3 blackwater, loaded with bacteria and viruses, and it is not something to mop up with household cleaners.
One free call connects you with an independent local specialist. Areas served include zip codes 90040 90022 90023 90091.

We are a referral line, not a contractor. Calls are routed to independent local pros around Commerce who handle biohazard sewage cleanup, not just clean-water leaks.
Crews wear disposable coveralls, nitrile gloves, rubber boots, eye protection, and respirators so pathogens do not leave the work area on their clothes.
Plastic barriers seal off the affected area, and HEPA air scrubbers create negative pressure so contaminated air does not drift into clean rooms.
Confirm license and insurance on arrival. Biohazard jobs should only go to properly insured pros.
You get a written estimate that covers removal, disinfection, and drying before work starts.

Sewage cleanup follows a strict order: contain, remove, clean, disinfect, verify, then dry. Skipping a step can leave pathogens behind long after the smell is gone.

Sewage is pumped and vacuumed out with equipment reserved for contaminated water, then disposed of properly.
Carpet, pad, drywall, insulation, and particleboard that touched sewage cannot be reliably disinfected and are bagged and removed.
Concrete, framing, and tile are cleaned and disinfected with EPA-registered products at the correct dwell time.
After disinfection, HEPA air scrubbers and odor control treatments remove lingering sewage odor from the air and structure.
Some contractors use ATP surface testing to confirm cleaning worked. Then drying equipment runs until materials read dry.
Call +1-877-637-9008, describe where sewage is coming up, and confirm everyone has stopped using water in the house.
A local contractor calls back with an arrival window and reminds you to keep everyone away from the contaminated area.
The pro sets up containment, assesses how far contamination reached, and gives you a written estimate before removal begins.
Contaminated materials are removed, surfaces disinfected, odors treated, and the area dried. The contractor may recommend a plumber to clear or camera the main line.
Stop using water and keep everyone away. Help can be on the way now.

Omar H.Recurring sewer backup

Sewage is Category 3 water, the most contaminated class. It contains bacteria, viruses, and parasites and requires protective gear, removal of porous materials, and disinfection.
It depends on the size of the backup and where it is. Small contained areas may be fine with containment in place. Large backups, or households with infants, elderly, or immune-compromised people, often warrant staying elsewhere.
Tiny spills on tile may be manageable with protection. Anything soaked into carpet or walls should be handled by a pro.
Many standard policies exclude sewer backup unless you have a specific sewer or drain backup endorsement. Check your policy with your agent.
Tree roots, grease clogs, damaged pipes, and city sewer overloads are the usual culprits.
