Sewage Backup Cleanup Solutions
Here's what a proper sewage job includes.
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
Every remaining surface is cleaned and disinfected with registered products. 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
Common causes include root intrusion, grease, collapsed pipe, or city sewer overload. A sewer camera pinpoints the problem, and a backwater valve guards against recurrence.

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

Tree roots blocked our main line and sewage came up through the basement shower drain. They set containment, removed the carpet and lower drywall, and sanitized the whole area. You couldn't smell a thing after.
— Alan G., WalthamI was ready to clean it up with bleach. They explained why porous materials had to be removed and why bleach alone wouldn't do it.
— Samantha K., WalthamThe 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., WalthamSewage Backup Cleanup Questions, Answered
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?
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.
