Why Mariposa Calls Us for Sewage Backups
Sewage cleanup is not a do-it-yourself job. Exposure can cause gastrointestinal illness and infections, and improper cleanup leaves contamination behind in materials you can't see into.

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.

Sewage Cleanup Work Through Our Network
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
After extraction, contaminated porous materials are cut out, bagged, and hauled off. Those materials can't be reliably sanitized.
Cleaning & Disinfection
Every remaining surface is cleaned and disinfected with registered products. 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.

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. They set containment, removed the carpet and lower drywall, and sanitized the whole area. You couldn't smell a thing after.
— Alan G., MariposaI 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., MariposaThe city sewer backed up into three houses on our street during a storm. The cleanup was thorough, and they suggested a backwater valve for the future.
— Henry L., MariposaCommon Questions About Sewage Backup Cleanup
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?
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.
