What Happens During Raw Sewage Cleanup in Somerville
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. Treat and verify
Disinfectant is applied to every affected surface, the space is dried and aired out, and the crew inspects the finished work.

Common Questions About Sewage Cleanup in Somerville
What if sewage backs up through a shower or tub?
Treat it as raw sewage. Keep people out of the bathroom, stop using the fixture and call for cleanup. The liquid can reach under flooring and into walls, so a crew checks beyond the visible puddle.
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 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.
How do I get sewage smell out of a house?
The smell comes from the contamination, so the fix is removing sewage and soaked materials first, then disinfecting and deodorizing. Air fresheners only cover it. If the odor persists, hidden material such as subfloor or insulation may still hold sewage.
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.
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.
