Many homes in Kennewick, about 51%, date from before 1980. Older plumbing is a common source of backups, and older flooring and trim soak up sewage deeply. Even without a major flood, Benton County has a Relatively Moderate river flood risk rating from FEMA. Storm runoff can enter sewers and cause backups into basements and low floors.
The work often covers:
- Containment and negative air to keep contamination out of unaffected rooms
- Disinfection of hard surfaces, framing and subfloors with EPA-registered products
- Cleaning and sanitizing of salvageable furniture, appliances and stored belongings
- Spot checks of the affected area and documentation for insurers and landlords
- Raw sewage removal from floors, basements, crawl spaces, garages and utility rooms

Common Questions About Sewage Cleanup in Kennewick
How much does a sewer backup cleanup cost?
The price depends on how much sewage there is, how far it spread and which materials must be removed. A bathroom overflow costs less than a flooded basement. The team sets the price after seeing the space, and nothing is decided on a call alone.
How long does sewage cleanup take?
Small jobs may be finished in a day, while larger ones with tear-out, drying and odor treatment take longer. The time depends on the area affected and what had to be removed. The crew can tell you what to expect after assessing the space.
How do I disinfect a basement after a sewer backup?
After the sewage and soaked materials are out, floors and walls are scrubbed with a cleaner, then treated with an EPA-registered disinfectant used by label directions. Unsealed concrete can hold odor and needs extra attention. Crews often handle this step with professional equipment.
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 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.
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.
