Common Questions About Sewage Cleanup in Kentfield

What is Category 3 water, also called black water?

Category 3 water is the most contaminated level, and sewage is the standard example. It can carry disease-causing germs and should never be cleaned with household supplies alone. Flood water that touched sewage is treated the same way.

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.

How do I clean sewage off concrete?

Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.

How do I clean up a sewer backup?

Keep people and pets out, turn off power if water is near outlets, and avoid touching the sewage. Safe cleanup needs protective gear, extraction, removal of soaked materials and disinfection. For anything more than a small spill, a cleanup company is the safer choice.

Who pays for sewage cleanup, the landlord or the tenant?

It depends on the cause, the lease and local law. A landlord's policy may cover the building, while a renter's policy may cover belongings. If the blockage was in a public sewer main, the city or utility may be responsible for the repair.

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.
