Why DuPont Calls Us for Sewage Backups

What Sewage Backup Cleanup Covers
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. ATP testing can confirm surfaces are clean.
Deodorization & Air Scrubbing
Air scrubbers and odor treatments clear the smell once contamination is gone. Real odor control means removing the source first.
Drain Line & Backflow Assessment
Backups often come from main line clogs, tree roots, grease buildup, or municipal sewer surcharges. A sewer camera pinpoints the problem, and a backwater valve guards against recurrence.

Sewage Cleanup Stories From DuPont
These callers all dealt with sewage in the house.

Tree roots blocked our main line and sewage came up through the basement shower drain. The crew sealed off the basement, pulled the carpet and drywall, and disinfected everything. You couldn't smell a thing after.
— Alan G., DuPontI was ready to clean it up with bleach. The contractor explained why the drywall had to go and why bleach wasn't enough.
— Samantha K., DuPontThe city sewer backed up into three houses on our street during a storm. They had our basement sanitized and recommended a backwater valve so it doesn't happen again.
— Henry L., DuPontWhat People Ask About Sewage Backups
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?
For anything beyond a minor spill on tile, it's best left to professionals who have protective gear and know which materials must be removed.
What causes sewage backups?
Roots, grease, flushed wipes, damaged pipe, and storm overload of city sewers cause most backups.
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.
