Professional Sewage Cleanup for Princeton Properties
Sewage cleanup is the removal of raw sewage and everything it soaked into, followed by cleaning and disinfection of the affected area. Because sewage carries bacteria and viruses, it is handled as a biohazard.
When sewage backs up in your Princeton property, call Princeton Biohazard Cleanup Help for a crew that treats it as a Category 3 biohazard. The team removes the sewage, discards contaminated materials and disinfects the affected area in Mercer County with EPA-registered products.
About 45% of households in Princeton rent, so sewage backups often involve a landlord, a property manager and a tenant at once. Clear documentation of the cleanup helps everyone. With roughly 48 inches of annual rainfall in Princeton, saturated ground and storm runoff add pressure to sewer pipes, a common cause of basement and crawl space backups.
A typical sewage & biohazard cleanup job includes:
- Septic tank and lift station overflow cleanup inside and around buildings
- Disinfection of hard surfaces, framing and subfloors with EPA-registered products
- Commercial sewage cleanup in restaurants, offices, shops and apartment buildings
- Cleanup of sewage under a house or in a crawl space where pipes have failed
- Odor removal and deodorizing after the sewage has been taken out

Sewer Backup Questions Answered for Princeton, NJ
How do I clean up a sewer backup?
Keep people and pets out, turn off power if water is near outlets, and avoid touching the sewage. Safe cleanup needs protective gear, extraction, removal of soaked materials and disinfection. For anything more than a small spill, a cleanup company is the safer choice.
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.
What is Category 3 water, also called black water?
Category 3 water is the most contaminated level, and sewage is the standard example. It can carry disease-causing germs and should never be cleaned with household supplies alone. Flood water that touched sewage is treated the same way.
How long does it take to get sick from raw sewage?
Symptoms such as stomach cramps, vomiting and diarrhea can start within hours or take a few days. Anyone with symptoms after exposure should contact a doctor. Children, older adults and people with weak immune systems are at higher risk.
Can I clean sewage myself?
A very small spill on a hard floor can be handled with gloves, boots, eye protection and a disinfectant used by label directions. Anything that reached carpet, drywall or a large area needs professional cleanup, because hidden contamination is hard to see.
Is a sewage backup a biohazard?
Yes. Raw sewage is Category 3 contamination and can carry bacteria, viruses and parasites. That is why cleanup crews wear protective gear and remove porous materials instead of just drying them.
