Sewage Backup Cleanup for King Owners, Landlords and Managers
Commercial sewage cleanup is the same biohazard work done in shops, restaurants, offices and apartment buildings, where many people share the space and the area must be cleared and sanitized before use resumes.
When sewage backs up in your King property, call King 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 Multnomah County with EPA-registered products.
King typically receives about 44 inches of rain a year, and heavy storms can overwhelm sewers and send wastewater up through drains. Renters make up about 48% of households in Portland. Tenants should tell the landlord right away, and the cleanup team can provide documentation for the lease and any claim.
The work often covers:
- Decontamination of HVAC components and air paths when sewage odor has spread
- Sanitizing after sewage reaches concrete slabs, tile grout and unfinished basement walls
- Spot checks of the affected area and documentation for insurers and landlords
- Cleanup after toilet, tub, shower and floor drain overflows
- Disinfection of hard surfaces, framing and subfloors with EPA-registered products
What Happens During Raw Sewage Cleanup in King
2. Sewage extraction
Standing sewage is pumped or scooped out, and the contaminated area is mapped to see how far the liquid traveled.
3. Sanitize the structure
Framing, subfloor and concrete are cleaned and treated, since sewage can soak into surfaces that look dry.
4. Sanitizing and deodorizing
Remaining surfaces are washed and disinfected, and odor is removed at its source rather than covered up.

Common Questions About Sewage Cleanup in King
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.
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 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.
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.
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.
