Why Lagunitas-Forest Knolls 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. That protects your family and the rest of the house.

Clear Pricing Before Work

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. 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
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. 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.

Sewage Cleanup Stories From Lagunitas-Forest Knolls
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. The crew sealed off the basement, pulled the carpet and drywall, and disinfected everything. You couldn't smell a thing after.
— Alan G., Lagunitas-Forest KnollsI almost tried to handle it myself with bleach. The contractor explained why the drywall had to go and why bleach wasn't enough.
— Samantha K., Lagunitas-Forest KnollsThe 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?
Roots, grease, flushed wipes, damaged pipe, and storm overload of city sewers cause most backups.
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.
