💧 Professional Water Leak Detection in Northern NJ

Hidden water leaks can cause thousands of dollars in structural damage — and most go unnoticed until the damage is severe. Advantage Plumbing uses advanced, non-invasive leak detection technology to pinpoint hidden leaks behind walls, under slabs, and underground without unnecessary demolition. We serve all of Northern New Jersey with fast, accurate leak detection and repair.

Signs of a Hidden Water Leak

Many water leaks hide for months before they're discovered. Warning signs include: an unexplained increase in your water bill, the sound of running water when no fixtures are in use, damp or warm spots on floors or walls, mold or mildew appearing without an obvious moisture source, low water pressure throughout the home, and water stains on ceilings or walls. If you notice any of these signs, call Advantage Plumbing for a leak detection inspection.

Electronic Leak Detection Technology

We use professional acoustic listening devices and electronic amplification equipment to detect the sound of water escaping from pressurized pipes — even through concrete slabs and thick walls. This non-invasive technology allows us to pinpoint a leak to within inches of its location, dramatically reducing the amount of opening up required to make the repair.

Slab Leak Detection & Repair

Slab leaks — leaks in pipes running beneath a concrete slab foundation — are among the most damaging and difficult to detect. Signs include warm spots on the floor, the sound of water under the floor, and unexplained increases in water bills. Our technicians use electronic detection equipment and thermal imaging to locate slab leaks precisely, then use the least invasive method possible to access and repair the pipe.

Pipe Pressure Testing

If you suspect a leak but can't locate it, pressure testing isolates the affected portion of your plumbing system. We isolate pipe sections and measure pressure drop to confirm whether a leak exists and narrow down its location. This is particularly useful for underground supply lines and irrigation systems.

Leak Repair

Finding the leak is only half the job — we also fix it. Once the leak is located, our plumbers repair or replace the damaged pipe section using the appropriate method for the pipe material and location. We restore any opened surfaces and ensure the repair is solid before we leave.
