- Cleaning and sanitizing of salvageable furniture, appliances and stored belongings
- Tear-out of sewage-soaked carpet, padding, drywall, baseboards and insulation
- Containment and negative air to keep contamination out of unaffected rooms
- Decontamination of HVAC components and air paths when sewage odor has spread
The Sewage Backup Cleanup Process in Ontario
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.

Raw Sewage Cleanup: Questions from Ontario, OR Property Owners
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.
Do plumbers clean up sewage?
Plumbers usually clear the blockage or repair the pipe, but most do not remove contaminated materials or disinfect the space. A sewage cleanup company picks up where the plumber stops, and the two jobs often happen in sequence.
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.
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.
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.
