What North Jersey Homeowners Say
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.
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.
