Sewage Cleanup Frequently Asked Questions in Lynn / Highland Park, Oakland, CA
What are the signs of a sewage leak?
Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.
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.
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.
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.
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.
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.
