Heavy rain overwhelms storm drains and pushes water into basements, including basement apartments. Sump pumps and backwater valves are common defenses. Barrier islands and bayfront towns face surge during hurricanes and nor'easters, and many homes there have been elevated since Sandy. Older cities like Newark, Jersey City and Paterson have aging water and sewer lines, and backups during storms are common.
In Newark: The remnants of Ida in 2021 caused severe flash flooding across northern New Jersey, filling basements in Newark and nearby cities. In Trenton: The river flooded low-lying areas three years in a row from 2004 to 2006. In Paterson: Irene and Ida pushed the river into homes in low neighborhoods. In Jersey City: Sandy's 2012 surge flooded Downtown and the waterfront.
Pre-war homes and two-family houses are common in north Jersey, with Cape Cods and split-levels in the suburbs. Finished basements raise the cost of any water loss.
New Jersey requires home improvement contractors to register with the Division of Consumer Affairs. Ask for the registration number, which must appear on contracts and ads.

Sewage & Biohazard Cleanup questions
Is basement flooding covered by insurance in New Jersey?
It depends on the source. Flood water from outside needs a flood policy, sewer or drain backup usually needs a water backup endorsement, and a burst pipe is typically covered by homeowners insurance.
How do I check a New Jersey home improvement contractor?
Look up their registration with the New Jersey Division of Consumer Affairs, and confirm their insurance before work starts.
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.
