Hackensack's choice for leak detection & repair

Looking for dependable leak detection & repair in Hackensack, NJ 07601? FlowMaster's licensed technicians cover every corner of Hackensack — and nearby Edgewater and Cliffside Park — with same-day and emergency leak detection.

Here's what makes Hackensack different: as the Bergen County seat, Hackensack mixes dense older housing and downtown commercial blocks where original sewer laterals and grease-loaded restaurant lines keep our jetting crews busy. Slab and underground supply leaks are common in North Jersey’s mid-century homes — pinpointing them saves the floor and the foundation.

Whether you're near the center of Hackensack, out toward Fairview, or anywhere in the 07601 area, a FlowMaster technician can be on the way fast — backed by the same guarantee that's made us a trusted name from Hackensack to your street.

What North Jersey Homeowners Say

4.9 from 127+ verified reviews
Our main line backed up on a Sunday and FlowMaster was at the house within the hour. They camera-scoped the line, showed me the root intrusion on screen, and did a trenchless repair without tearing up the yard. Honest, fast, and the price was exactly what they quoted.

Kitchen sink had been slow for weeks. The tech hydro jetted the line, showed me before-and-after on the camera, and it’s draining better than it has in years. No upselling, just solid work.
James R. Drain Cleaning · Clifton, NJ
Burst pipe at 11pm flooding my basement. A real person answered, walked me through shutting the water off, and had a plumber here fast. They stopped the damage and fixed it that night. Lifesavers.
