Why Walnut Calls Us for Sewage Backups

Sewage Backup Cleanup Solutions
Sewage cleanup follows a strict sequence.
Area Isolation
Plastic barriers and negative air setups keep contaminated air and debris from reaching the rest of the house. Clean areas stay off-limits to contaminated foot traffic.
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
Air scrubbers and odor treatments clear the smell once contamination is gone. Masking odor without removing the source never works.
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.

Is sewage backup dangerous?
It is. Sewage contains pathogens that can cause gastrointestinal illness and infections, so avoid contact and keep the area closed off.
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?
Roots, grease, flushed wipes, damaged pipe, and storm overload of city sewers cause most backups.
Does insurance cover sewage backup?
Many standard homeowners policies exclude sewer backup unless you've added a sewer or water backup endorsement. Check your policy and call your agent to confirm.
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.
