Raw Sewage Cleanup in Florissant, MO: What the Work Involves

Commercial sewage cleanup is the same biohazard work done in shops, restaurants, offices and apartment buildings, where many people share the space and the area must be cleared and sanitized before use resumes.

When sewage backs up in your Florissant property, call Florissant Biohazard Cleanup Help for a crew that treats it as a Category 3 biohazard. The team removes the sewage, discards contaminated materials and disinfects the affected area in St. Louis County with EPA-registered products.

With roughly 42 inches of annual rainfall in Florissant, saturated ground and storm runoff add pressure to sewer pipes, a common cause of basement and crawl space backups. With a Relatively High river flood risk rating from FEMA for St. Louis County, flood events here can mix floodwater with sewage, which is treated as Category 3 contamination.

A typical sewage & biohazard cleanup job includes:

  • Raw sewage removal from floors, basements, crawl spaces, garages and utility rooms
  • Bagging and proper disposal of contaminated materials as hazardous waste
  • Cleanup of sewage under a house or in a crawl space where pipes have failed
  • Tear-out of sewage-soaked carpet, padding, drywall, baseboards and insulation
  • Cleanup after toilet, tub, shower and floor drain overflows

How a Sewage Cleanup Company Works a Job in Florissant, MO

1. Call and plan

The team asks what happened, where the sewage is and who uses the space, then plans the right crew and equipment.

2. Pump and remove

Wastewater is taken out of the building, and standing liquid in crawl spaces or low corners is cleared.

3. Decontaminate

Contaminated materials are bagged and removed, and surfaces are scrubbed and treated with hospital-grade disinfectant.

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 Florissant

What are the signs of a sewage leak?

Watch for a rotten-egg or sewer smell, wet spots or stains on floors and walls, unusually green grass over a pipe, and multiple drains backing up at the same time. If any of these show up, keep people away from the area and have the cause checked.

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 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.

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.

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 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.
