Sewage & Biohazard Cleanup questions
Do I need a permit for repairs in Norwalk?
Cleanup and drying don't. Structural, plumbing and electrical repairs need permits from the City of Norwalk Building Department.
Do I need flood insurance in Norwalk?
Homeowners policies exclude flood. Coastal and riverside neighborhoods are in FEMA flood zones.
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.
