A hidden leak can quietly rot framing, breed mold, and double your water bill long before you ever see a drip. FlowMaster uses acoustic and electronic leak-detection equipment to pinpoint the source without demolishing your home, then makes a targeted repair.
What is leak detection & repair?
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.
Slab and underground supply leaks are common in North Jersey’s mid-century homes — pinpointing them saves the floor and the foundation.
