A sewer backup is wastewater forced back up through a drain or toilet into living space. Sewage backup cleanup removes that wastewater, disposes of contaminated materials and treats surfaces and odors.

With roughly 42 inches of annual rainfall in Nassau, saturated ground and storm runoff add pressure to sewer pipes, a common cause of basement and crawl space backups. About 91% of homes in Nassau were built before 1980, and older clay or cast iron sewer pipes crack and clog with roots over time.
The work often covers:
- Decontamination of HVAC components and air paths when sewage odor has spread
- Odor removal and deodorizing after the sewage has been taken out
- Cleanup of sewage under a house or in a crawl space where pipes have failed
- Cleaning and sanitizing of salvageable furniture, appliances and stored belongings
- Septic tank and lift station overflow cleanup inside and around buildings

3. Cleanup and tear-out
Liquid is removed first, then anything that cannot be cleaned, such as soaked flooring and wall board.

Raw Sewage Cleanup: Questions from Nassau, NY Property Owners
Who pays for sewage cleanup, the landlord or the tenant?
It depends on the cause, the lease and local law. A landlord's policy may cover the building, while a renter's policy may cover belongings. If the blockage was in a public sewer main, the city or utility may be responsible for the repair.
How do I know if sewage is leaking under my house?
Common signs include a sewer smell in the yard or crawl space, soft or damp ground near the foundation, gurgling drains and slow drains in several fixtures at once. A plumber can confirm the leak. Once it is found, a cleanup team can take care of the contaminated soil, materials and odor.
What if sewage backs up through a shower or tub?
Treat it as raw sewage. Keep people out of the bathroom, stop using the fixture and call for cleanup. The liquid can reach under flooring and into walls, so a crew checks beyond the visible puddle.
Does homeowners insurance cover sewage backup?
Often only with an added endorsement. Many standard policies treat sewer or drain backup separately from sudden water damage. Call your insurer before cleanup begins, take photos and keep receipts, and ask what they need to see.
Why does drywall have to be removed after sewage?
Drywall is porous and holds contamination that can spread germs and odor long after the surface looks clean. Crews usually cut out wall board that sewage touched, and often take out a margin above the wet mark to reach clean material.
Do sewage cleanup companies handle commercial properties?
Yes. Commercial sewage cleanup in restaurants, offices, shops and apartment buildings follows the same biohazard steps, with added attention to keeping part of the building usable and to documentation for managers and insurers.
