With roughly 44 inches of annual rainfall in Mehlville, saturated ground and storm runoff add pressure to sewer pipes, a common cause of basement and crawl space backups. Many homes in Mehlville, about 71%, date from before 1980. Older plumbing is a common source of backups, and older flooring and trim soak up sewage deeply.
A typical sewage & biohazard cleanup job includes:
- Tear-out of sewage-soaked carpet, padding, drywall, baseboards and insulation
- Commercial sewage cleanup in restaurants, offices, shops and apartment buildings
- Odor removal and deodorizing after the sewage has been taken out
- Disinfection of hard surfaces, framing and subfloors with EPA-registered products

The Sewage Backup Cleanup Process in Mehlville
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.

Sewer Backup Questions Answered for Mehlville, MO
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.
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.
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.
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.
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 I clean sewage myself?
A very small spill on a hard floor can be handled with gloves, boots, eye protection and a disinfectant used by label directions. Anything that reached carpet, drywall or a large area needs professional cleanup, because hidden contamination is hard to see.
