Sewage & Biohazard 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.
Can I clean up a small sewage backup myself?
A small backup on a hard, non-porous floor sometimes can be with gloves, boots and disinfectant. Anything that reached carpet, drywall or other porous materials needs professional cleanup.
Does homeowners insurance cover sewage backups?
Usually only with a sewer or drain backup endorsement. Flooding from outside needs a flood policy.
