Why Choose Our Specialized Sewage Backup Cleanup in Larkspur, CA
Sewage cleanup is not a do-it-yourself job. Contact with raw sewage carries real health risks, and poor cleanup leaves pathogens in porous materials.

Clear Pricing Before Work
You get a written estimate covering removal, disinfection, and drying. The estimate includes disposal of contaminated waste.
Rapid Local Response

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. Foot traffic is limited to protect clean rooms.
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
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
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.

Sewage Cleanup Stories From Larkspur

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.

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.
