Professional Sewage Cleanup for St. Francis Wood Properties
A sewage clean up service treats a backup as a health problem first and a mess second. The work covers extraction, tear-out of contaminated materials, disinfection and odor removal.
When sewage backs up in your St. Francis Wood property, call St. Francis Wood 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.
With a Relatively High river flood risk rating from FEMA for San Francisco County, flood events here can mix floodwater with sewage, which is treated as Category 3 contamination. 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:
- Odor removal and deodorizing after the sewage has been taken out
- Disinfection of hard surfaces, framing and subfloors with EPA-registered products
- Tear-out of sewage-soaked carpet, padding, drywall, baseboards and insulation
- Cleanup of sewage under a house or in a crawl space where pipes have failed
- Bagging and proper disposal of contaminated materials as hazardous waste

Common Questions About Sewage Cleanup in St. Francis Wood
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.
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.
Should I call a plumber or a cleanup company first?
If sewage is still coming up, a plumber may need to stop the source. If sewage is already on the floor, a cleanup team can start containing it at once. Many property owners call both, and it does not matter much which is first. Sewer backup companies and plumbers often work one after the other on the same job.
What are the signs of a sewage leak?
Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.
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.
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.
