Sewage Backup Cleanup for Parkmerced Owners, Landlords and Managers
Sewage cleanup is the removal of raw sewage and everything it soaked into, followed by cleaning and disinfection of the affected area. Because sewage carries bacteria and viruses, it is handled as a biohazard.
When sewage backs up in your Parkmerced property, call Parkmerced Biohazard Cleanup Help for a crew that treats it as a Category 3 biohazard. The team removes the sewage, discards contaminated materials and disinfects the affected area in San Francisco County with EPA-registered products.
San Francisco County carries a Relatively High river flood risk rating from FEMA, and rising water can overload sewer pipes and push wastewater back up through floor drains. Many homes in San Francisco, about 76%, date from before 1980. Older plumbing is a common source of backups, and older flooring and trim soak up sewage deeply.
The work often covers:
- Raw sewage removal from floors, basements, crawl spaces, garages and utility rooms
- Disinfection of hard surfaces, framing and subfloors with EPA-registered products
- Cleaning and sanitizing of salvageable furniture, appliances and stored belongings
- Bagging and proper disposal of contaminated materials as hazardous waste
- Commercial sewage cleanup in restaurants, offices, shops and apartment buildings

Sewage Cleanup Frequently Asked Questions in Parkmerced, San Francisco, CA
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.
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.
What illnesses can raw sewage cause?
Sewage can carry germs such as E. coli, norovirus, hepatitis A and Giardia. They spread through skin contact, splashes and hand to mouth contact. Washing well and wearing protection reduce the risk, but removal by a crew reduces it most.
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.
Can sewage backup make me sick even after it is cleaned up?
If the cleanup missed contaminated materials, germs and odor can linger. That is why crews remove porous materials, disinfect every surface they touched and inspect the work. Thorough removal is what lowers the risk.
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.
