Common Questions About Sewage Cleanup in South of Market
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.
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.
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 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.
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.
