Why Altadena 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.

What Sewage Backup Cleanup Covers
Sewage cleanup follows a strict sequence.
Area Isolation
Containment walls and air scrubbers isolate the affected area. 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
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. 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 plumber's camera inspection finds the cause, and a backwater valve can help prevent a repeat.

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?
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?
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.
