Sewage backup cleanup questions
Is flood insurance worth it in Missouri?
If you're near a river or in a flood zone, yes. Homeowners policies exclude flood, and flash flooding can affect areas outside mapped zones.
Do Missouri contractors need a license?
Licensing is local. Check with your city or county, and ask for insurance.
Does homeowners insurance cover sewage backup?
Often only with a water or sewer backup endorsement, which most insurers offer as an add-on. Check your declarations page.
Is sewage cleanup dangerous?
Yes. Sewage contains bacteria, viruses and parasites. Professional crews use protective equipment and disinfectants for this reason.
