Trusted leak detection & repair in Cranford

Cranford homeowners call FlowMaster for leak detection & repair because we answer the phone 24/7, quote a flat rate before we start, and fix it the first time. From Linden to Rahway, we keep Union County running.

Slab and underground supply leaks are common in North Jersey’s mid-century homes — pinpointing them saves the floor and the foundation. That's a big reason Cranford residents keep FlowMaster on speed dial. Cranford floods notoriously along the Rahway River, making sump pumps and backflow prevention critical.

From the first call to the final cleanup, Cranford homeowners get a licensed pro, a price agreed in writing, and leak detection that lasts. We serve all of Cranford and neighboring Linden, Rahway, and Westfield.

What leak detection & repair involves

Leak detection uses acoustic sensors, thermal imaging, and pressure testing to locate concealed leaks in supply lines, drains, slabs, and underground service lines — so repairs are precise instead of exploratory.

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.
Maria D. Sewer Line Repair · Ridgewood, NJ
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.
