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
Waste and water are extracted, then porous materials like carpet, pad, drywall, and insulation that contacted sewage are bagged and removed. Those materials can't be reliably sanitized.
Cleaning & Disinfection
Hard surfaces and framing are scrubbed and treated with EPA-registered disinfectants. ATP testing can confirm surfaces are clean.
Deodorization & Air Scrubbing
HEPA air scrubbers and deodorization treatments remove lingering odor after cleanup. 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.

Sewage Cleanup Stories From Keene
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. The crew sealed off the basement, pulled the carpet and drywall, and disinfected everything. You couldn't smell a thing after.
— Alan G., KeeneI 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., KeeneA storm surcharged the city line and backed into several homes on our block. They had our basement sanitized and recommended a backwater valve so it doesn't happen again.
— Henry L., KeeneWhat People Ask About Sewage Backups
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?
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?
A camera inspection, regular line maintenance, and a backwater valve are the best defenses, along with keeping grease and wipes out of the drains.
