Raw Sewage Cleanup: Questions from Mar Lee, Denver, CO Property Owners
Can a sewage cleanup service work at night or on weekends?
Yes. Sewage backups do not wait for business hours, so you can call Mar Lee Biohazard Cleanup Help any time, 24/7. Describe what happened and you get the next safe step explained.
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 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.
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.
How do I disinfect a basement after a sewer backup?
After the sewage and soaked materials are out, floors and walls are scrubbed with a cleaner, then treated with an EPA-registered disinfectant used by label directions. Unsealed concrete can hold odor and needs extra attention. Crews often handle this step with professional equipment.
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.
