Leak Detection in NJ
A hidden leak can quietly rot framing, ruin drywall, and spike your water bill for months. Our licensed plumbers use acoustic sensors, thermal imaging, and pressure testing to locate the exact source — no demolition guesswork — then repair it cleanly, calling in an emergency plumber if a pipe has already burst.
Watch for an unexplained jump in your water bill, the sound of running water when everything is off, damp spots or stains, low pressure, or a musty smell that may point to hidden mold.
The meter test is a homeowner's first tool: shut every fixture, note the meter reading, wait thirty minutes, and check again. Movement with everything off confirms water is escaping somewhere — and that's when precision location equipment earns its keep.
Slab Leaks
Leaks in the pipes beneath your concrete slab are especially damaging and hard to spot. Signs include warm spots on the floor, cracks, and the sound of running water. We locate slab leaks precisely and repair or reroute the line with minimal disruption — and if the line ties into your main sewer, we handle that too.
Repair strategy depends on the run: a single bad spot can be opened and patched, but aging copper that's failed once often gets rerouted overhead instead — abandoning the slab run entirely so the same pipe can't fail twice.
Burst Pipes
From frozen winter pipe bursts to corroded older lines, we repair and replace damaged pipe fast — and our 24/7 emergency team responds the moment a line lets go. For aging galvanized or polybutylene plumbing common in older New Jersey homes, we offer repiping with modern, long-lasting materials.
Prevention is mostly about the freeze points: hose bibs left connected, uninsulated runs along rim joists, and pipes in exterior walls. A quick fall visit hardens all three before the first deep freeze.
Non-Invasive Detection & Service Area
Our goal is to find the leak with the least possible disruption to your home. Slab-on-grade ranches near the shore hide leaks differently than basemented colonials inland — our technicians chase down both every week, in all three counties we serve.
Frequently Asked Questions
How much does leak detection cost in NJ?
Professional leak detection in New Jersey typically ranges from about $150 to $450 depending on the complexity, and the cost is well worth avoiding thousands in water damage. We quote it upfront and credit it toward the repair when possible.
What are the signs of a slab leak?
Common signs include warm spots on the floor, the sound of running water when nothing is on, an unexplained spike in your water bill, and cracks or damp areas in flooring. We confirm and locate it with non-invasive tools.
How do you find a hidden water leak?
We use acoustic listening equipment, thermal imaging, and pressure testing to pinpoint the exact location behind walls, under floors, or in the slab — no unnecessary demolition.
Is a hidden leak a plumbing emergency?
A fast leak or burst pipe is an emergency — shut off the water and call us right away. A slow hidden leak still needs prompt attention to prevent mold and structural damage, but can usually be scheduled same- or next-day.
