A main line backup sends raw sewage up through the lowest drains in the house, usually a basement shower, floor drain, or toilet. That water carries E. coli, hepatitis, and other pathogens. Safe cleanup means containment, protective gear, removal of everything porous it touched, and thorough disinfection.
Free referral to independent, licensed and insured local pros. Zip codes served include 91016 91017 91185.

We are a referral line, not a contractor. Calls are routed to independent local pros around Monrovia who handle biohazard sewage cleanup, not just clean-water leaks.
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.
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.
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.
Cleanliness is checked, sometimes with ATP swab testing, before drying gets the area ready for rebuild.
Tell dispatch which drains are backing up and how far the sewage spread.
A local contractor calls back with an arrival window and reminds you to keep everyone away from the contaminated area.
Containment goes up first, then the pro maps the contamination and provides a written quote.
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.
Raw sewage is a health risk. Get a protected crew out fast.
Main line backed up into the basement shower and floor drain. The crew showed up in full suits, sealed off the basement, and cleaned it like a hospital. No smell after they left.
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

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.
Small, contained jobs may be fine. For large backups or vulnerable family members, staying elsewhere is often safer.
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.
Often only with a sewer backup add-on. Your agent can tell you what your policy includes.
Common causes include tree roots in the main line, grease buildup, collapsed or bellied pipes, and municipal sewer overloads during heavy rain.
