Many homes in Walla Walla County, about 60%, date from before 1980. Older plumbing is a common source of backups, and older flooring and trim soak up sewage deeply. Walla Walla East averages about 19 inches of rain a year. Backups here usually come from blockages, roots or broken pipes rather than storms, but the cleanup is the same.
The work often covers:
- Cleanup of sewage under a house or in a crawl space where pipes have failed
- Spot checks of the affected area and documentation for insurers and landlords
- Septic tank and lift station overflow cleanup inside and around buildings
- Cleanup after toilet, tub, shower and floor drain overflows
- Decontamination of HVAC components and air paths when sewage odor has spread
How Sewage Cleanup Works in Walla Walla East, WA
2. Isolate and protect
Plastic barriers and air controls go up, and technicians suit up before they enter the sewage area.
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 Walla Walla East
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 should I do right after a sewage backup?
Keep everyone out of the area, including pets, and stop using sinks, tubs and toilets that feed the pipe. Turn off power to wet areas only if it is safe. Then call a cleanup team and your insurer, and take photos before anything is moved.
Can carpet be saved after a sewage backup?
Usually not. Carpet and padding soak up Category 3 water and cannot be reliably made safe, so they are cut out and discarded. Hard surfaces, sealed wood and items in closed containers can often be cleaned and kept.
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.
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.
What is Category 3 water, also called black water?
Category 3 water is the most contaminated level, and sewage is the standard example. It can carry disease-causing germs and should never be cleaned with household supplies alone. Flood water that touched sewage is treated the same way.
