Common Questions About Sewage Cleanup in Andover
Can a sewage cleanup service work at night or on weekends?
Yes. Sewage backups do not wait for business hours, so you can call Andover Biohazard Cleanup Help any time, 24/7. Describe what happened and you get the next safe step explained.
Is a sewage backup a biohazard?
Yes. Raw sewage is Category 3 contamination and can carry bacteria, viruses and parasites. That is why cleanup crews wear protective gear and remove porous materials instead of just drying them.
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 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.
How do I clean sewage off concrete?
Concrete is porous, so sewage soaks in. The surface is scrubbed, rinsed and treated with a disinfectant, and the wash water is collected rather than spread. Stubborn odor may need a second round of treatment.
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.
