Common Questions About Sewage Cleanup in Tamalpais-Homestead Valley
What illnesses can raw sewage cause?
Sewage can carry germs such as E. coli, norovirus, hepatitis A and Giardia. They spread through skin contact, splashes and hand to mouth contact. Washing well and wearing protection reduce the risk, but removal by a crew reduces it most.
Why does drywall have to be removed after sewage?
Drywall is porous and holds contamination that can spread germs and odor long after the surface looks clean. Crews usually cut out wall board that sewage touched, and often take out a margin above the wet mark to reach clean material.
Do sewage cleanup companies handle commercial properties?
Yes. Commercial sewage cleanup in restaurants, offices, shops and apartment buildings follows the same biohazard steps, with added attention to keeping part of the building usable and to documentation for managers and insurers.
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.
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.
Is a sewage backup a biohazard?
Yes. Raw sewage is Category 3 contamination and can carry bacteria, viruses and parasites. That is why cleanup crews wear protective gear and remove porous materials instead of just drying them.
