Why Coronado Calls Us for Sewage Backups
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. It keeps contamination from spreading to unaffected rooms.

What Sewage Backup Cleanup Covers
Sewage cleanup follows a strict sequence.
Area Isolation
Containment walls and air scrubbers isolate the affected area. 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. 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
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 sewer camera pinpoints the problem, and a backwater valve guards against recurrence.

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?
Many standard homeowners policies exclude sewer backup unless you've added a sewer or water backup endorsement. Check your policy and call your agent to confirm.
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.
