How Sewage Cleanup Works in Orinda, CA

1. Call and plan

The team asks what happened, where the sewage is and who uses the space, then plans the right crew and equipment.

2. Remove the liquid

The team takes out all standing wastewater and wipes down wet surfaces before touching anything else.

3. Cleanup and tear-out

Liquid is removed first, then anything that cannot be cleaned, such as soaked flooring and wall board.

Disinfectant is applied to every affected surface, the space is dried and aired out, and the crew inspects the finished work.

Sewer Backup Questions Answered for Orinda, CA

How long does it take to get sick from raw sewage?

Symptoms such as stomach cramps, vomiting and diarrhea can start within hours or take a few days. Anyone with symptoms after exposure should contact a doctor. Children, older adults and people with weak immune systems are at higher risk.

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.

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.

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.

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.

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.
