Why Sunnyside Calls Us for Sewage Backups
This isn't something to tackle with household cleaners. 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 Backup Cleanup Solutions
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. Foot traffic is limited to protect clean rooms.
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. Some contractors verify cleanliness with ATP swab testing.
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
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.

Roots clogged the main and sewage backed up into the basement shower. They set containment, removed the carpet and lower drywall, and sanitized the whole area. You couldn't smell a thing after.
— Alan G., SunnysideI 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., SunnysideThe 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., SunnysideCommon 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?
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?
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.
