Sewage backup cleanup in New Jersey
Sewage cleanup treats the water as Category 3 (grossly contaminated): crews in protective gear remove it, discard porous materials it touched, clean and disinfect hard surfaces, and dry the structure. Don't try to clean sewage with household products and a mop.

In Newark: Newark's older combined sewer system can back up into basements during heavy rain. In Trenton: Leaks and backups travel through shared walls between rowhomes. In Paterson: Combined sewers back up into basements during heavy storms. In Jersey City: Heavy rain overloads combined sewers and backs water into basements.

Sewage backup 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.
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.
