What Sewage Cleanup Through Our Network Includes
This isn't something to tackle with household cleaners. Contact with raw sewage carries real health risks, and poor cleanup leaves pathogens in porous materials.

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.

Clear Pricing Before Work
Removal, sanitizing, and drying are quoted in writing. Disposal of contaminated materials is spelled out too.
Rapid Local Response
Every hour sewage sits, contamination spreads further. We route your call to an available contractor near Covington right away.
What Sewage Backup Cleanup Covers
Here's what a proper sewage job includes.
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
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. Masking odor without removing the source never works.
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.

When the Drain Backed Up
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. The crew sealed off the basement, pulled the carpet and drywall, and disinfected everything. You couldn't smell a thing after.
— Alan G., CovingtonI almost tried to handle it myself with bleach. They explained why porous materials had to be removed and why bleach alone wouldn't do it.
— Samantha K., CovingtonA 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.

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?
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.
