Open 24 hours
24/7 Emergency Sewer & Drain
A mainline backup, overflowing fixture, or sewage entering a cellar needs a calm first response and a diagnosis that matches the visible condition.
What to do right now
Stop running water and keep people and pets away from sewage. If water is near electrical equipment or the situation is unsafe, leave the area and contact the appropriate emergency service.
- Stop sinks, showers, laundry, and dishwashers
- Do not keep flushing a backed-up toilet
- Avoid contact with wastewater
- Tell us which fixtures are affected and when it started
Public main or private lateral?
When multiple nearby properties or a street condition point to the public sewer, NYC DEP may need to investigate. When the issue is isolated to your building, the private lateral or building drain is more likely. A camera inspection can help separate those paths.
After flow is restored
Opening the line is only the first step when a blockage keeps returning. The accessible run should be inspected so roots, damage, or recurring buildup are not mistaken for a one-time clog.
Frequently asked
Clear answers before the work.
Are you available overnight?
The business is open 24 hours. Call the owner directly to describe the current condition and confirm availability.
Should I call NYC DEP first?
Call 311 when there are signs of a public sewer problem, such as multiple properties affected or street-level evidence. For an isolated building backup, call a sewer professional.
Can I use chemical drain cleaner while I wait?
Avoid adding chemicals to a backed-up system. They may not reach the obstruction and can create an exposure risk for anyone working on the line.
Will the line be cameraed during an emergency?
Camera-first diagnosis is used when flow and access allow it. A fully blocked line may need to be opened before the camera can show the cause.
