Sewage Cleanup Frequently Asked Questions in Larkspur, 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.
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.
How do I know if sewage is leaking under my house?
Common signs include a sewer smell in the yard or crawl space, soft or damp ground near the foundation, gurgling drains and slow drains in several fixtures at once. A plumber can confirm the leak. Once it is found, a cleanup team can take care of the contaminated soil, materials and odor.
Can I clean sewage myself?
A very small spill on a hard floor can be handled with gloves, boots, eye protection and a disinfectant used by label directions. Anything that reached carpet, drywall or a large area needs professional cleanup, because hidden contamination is hard 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.
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.
