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.

Expect Tyvek-style suits, respirators, and gloves. Contaminants stay in the work zone, not tracked through your home.
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.

Proper sewage remediation is methodical. Contamination is removed, every surface is disinfected, and only then does drying begin.

Liquid sewage and solids are extracted with dedicated equipment and disposed of according to local rules, not dumped down another drain.
Carpet, pad, drywall, insulation, and particleboard that touched sewage cannot be reliably disinfected and are bagged and removed.
Hard surfaces are scrubbed, then treated with EPA-registered disinfectants left on for the full contact time listed on the label.
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.
Sewage and damaged materials come out, everything is sanitized and dried, and you will be pointed to a plumber if the line needs work.

Our main line backed up into the basement. They sealed it off, suited up, removed everything contaminated, and the smell was completely gone.

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.
