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.
Free referral to independent, licensed and insured local pros. Zip codes served include 98290 98258.

We are a referral line, not a contractor. Calls are routed to independent local pros around Bunk Foss 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.
Pricing for each phase is written down and approved by you first.

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.

Liquid sewage and solids are extracted with dedicated equipment and disposed of according to local rules, not dumped down another drain.
Anything porous that absorbed sewage, like carpet, drywall, and insulation, is removed and bagged.
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.
Tell dispatch which drains are backing up and how far the sewage spread.
You will get an arrival time and safety reminders while the crew is on the way.
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.
Our main line backed up into the basement. They sealed it off, suited up, removed everything contaminated, and the smell was completely gone.
Carmen E.Main line backup, basementHonest about what had to be thrown away and why. I appreciated the explanation.
Steve R.Toilet overflow into finished roomWith kids in the house, I wanted it contained. The plastic barrier and air scrubber kept it all downstairs.
Jenna P.Sewage backup, family homeThey recommended a plumber to camera the line afterward. Turned out to be tree roots. Glad we found it.
Omar H.Recurring sewer backup

It is Category 3, meaning grossly contaminated. That category triggers full biohazard protocols.
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.
A very small hard-surface spill can be cleaned with gloves, boots, and a disinfectant. If sewage reached carpet, drywall, or a large area, professional cleanup is the safer choice.
Many standard policies exclude sewer backup unless you have a specific sewer or drain backup endorsement. Check your policy with your agent.
Common causes include tree roots in the main line, grease buildup, collapsed or bellied pipes, and municipal sewer overloads during heavy rain.
