Why Atherton 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
Expect full protective gear and containment barriers before cleanup starts. It keeps contamination from spreading to unaffected rooms.

Sewage Cleanup Work Through Our Network
Here's what a proper sewage job includes.
Area Isolation
Containment walls and air scrubbers isolate the affected area. 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. Porous items can't be made safe after sewage contact.
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
Air scrubbers and odor treatments clear the smell once contamination is gone. Real odor control means removing the source first.
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.

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., AthertonI was ready to clean it up with bleach. The contractor explained why the drywall had to go and why bleach wasn't enough.
— Samantha K., AthertonThe city sewer backed up into three houses on our street during a storm. 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?
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?
Have the main line camera-inspected and cleared, avoid flushing wipes and pouring grease down drains, and consider a backwater valve, which lets sewage flow out but not back in.
