The work often covers:
- Cleanup after toilet, tub, shower and floor drain overflows
- Odor removal and deodorizing after the sewage has been taken out
- Commercial sewage cleanup in restaurants, offices, shops and apartment buildings
- Tear-out of sewage-soaked carpet, padding, drywall, baseboards and insulation

Raw Sewage Cleanup: Questions from Portola Valley, CA Property Owners
Does homeowners insurance cover sewage backup?
Often only with an added endorsement. Many standard policies treat sewer or drain backup separately from sudden water damage. Call your insurer before cleanup begins, take photos and keep receipts, and ask what they need to see.
Is sewage cleanup the same as water damage restoration?
No. Water from a clean source can often be dried in place, but sewage is a biohazard that requires removal of contaminated materials and disinfection. Drying alone does not make a sewage-affected space safe.
Can a sewage cleanup service work at night or on weekends?
Yes. Sewage backups do not wait for business hours, so you can call Portola Valley Biohazard Cleanup Help any time, 24/7. Describe what happened and you get the next safe step explained.
What if the sewage came from a septic tank?
A septic overflow is cleaned as raw sewage, both inside any affected building and on nearby ground. Contaminated soil, materials and surfaces are handled and disinfected. A septic service may also need to empty or repair the tank.
What if sewage backs up through a shower or tub?
Treat it as raw sewage. Keep people out of the bathroom, stop using the fixture and call for cleanup. The liquid can reach under flooring and into walls, so a crew checks beyond the visible puddle.
Do plumbers clean up sewage?
Plumbers usually clear the blockage or repair the pipe, but most do not remove contaminated materials or disinfect the space. A sewage cleanup company picks up where the plumber stops, and the two jobs often happen in sequence.
