What Sewage Cleanup Through Our Network Includes
Sewage cleanup is not a do-it-yourself job. Exposure can cause gastrointestinal illness and infections, and improper cleanup leaves contamination behind in materials you can't see into.

Proper PPE & Biohazard Protocols
Contractors wear respirators, eye protection, nitrile gloves, and protective suits, and set up containment to keep contamination out of clean areas. That protects your family and the rest of the house.
Licensed & Insured Independent Pros
We connect you with licensed and insured independent contractors experienced in Category 3 cleanup. Verify license and insurance with the contractor first.

Rapid Local Response

Sewage Cleanup Work Through Our Network
Sewage cleanup follows a strict sequence.
Area Isolation
Containment walls and air scrubbers isolate the affected area. Foot traffic is limited to protect clean rooms.
Sewage Extraction & Material Removal
After extraction, contaminated porous materials are cut out, bagged, and hauled off. Porous items can't be made safe after sewage contact.
Cleaning & Disinfection
Hard surfaces and framing are scrubbed and treated with EPA-registered disinfectants. Some contractors verify cleanliness with ATP swab testing.
Deodorization & Air Scrubbing
HEPA air scrubbers and deodorization treatments remove lingering odor after cleanup. Real odor control means removing the source first.
Drain Line & Backflow Assessment
Common causes include root intrusion, grease, collapsed pipe, or city sewer overload. A plumber's camera inspection finds the cause, and a backwater valve can help prevent a repeat.

What Callers Say After a Backup
Nobody wants to make this call, but these callers were glad they did.

Roots clogged the main and sewage backed up into the basement shower. They set containment, removed the carpet and lower drywall, and sanitized the whole area. You couldn't smell a thing after.
— Alan G., Lucas Valley-MarinwoodI almost tried to handle it myself with bleach. The contractor explained why the drywall had to go and why bleach wasn't enough.
— Samantha K., Lucas Valley-MarinwoodA storm surcharged the city line and backed into several homes on our block. The cleanup was thorough, and they suggested a backwater valve for the future.

Is sewage backup dangerous?
Yes. Raw sewage is Category 3 black water and can carry bacteria such as E. coli, viruses, and parasites. Skin contact, splashes, and contaminated air can all cause illness, so keep people and pets away until it's professionally cleaned.
Can I clean up sewage myself?
Small, contained spills on hard surfaces might be manageable with proper protection, but most backups involve porous materials and hidden contamination. Professional cleanup with PPE, containment, and registered disinfectants is the safer choice.
What causes sewage backups?
Common causes include tree root intrusion, grease or wipes clogging the line, collapsed or bellied sewer pipe, and heavy rain overloading municipal sewers.
Does insurance cover sewage backup?
Often only with a sewer backup endorsement. Without that rider, many policies don't cover it, so check your coverage.
How can I prevent sewage from backing up again?
Have the main line camera-inspected and cleared, avoid flushing wipes and pouring grease down drains, and consider a backwater valve, which lets sewage flow out but not back in.
