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.

Sewage is a health hazard first and a water problem second.

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.
Each contractor carries independent licensing and insurance. Ask for proof before work begins, especially for biohazard work.
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.

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, basementThey explained why the carpet and bottom of the drywall had to go. Not what I wanted to hear, but it made sense once they mentioned what is in sewage.
Steve R.Toilet overflow into finished roomI have little kids, so I was worried. They set up an air scrubber and plastic walls so nothing spread upstairs.
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.
Tiny spills on tile may be manageable with protection. Anything soaked into carpet or walls should be handled by a pro.
Often only with a sewer backup add-on. Your agent can tell you what your policy includes.
Tree roots, grease clogs, damaged pipes, and city sewer overloads are the usual culprits.
