Pipe failures range from a slow pinhole leak weeping inside a wall to a full main line rupture. Locating the failure precisely โ before opening drywall or digging โ is the skill that separates a clean, affordable repair from an expensive and destructive guessing operation. Masters Plumbing Service's pipe technicians in Cresskill, NJ use acoustic listening devices and thermal imaging cameras to find the leak first, then open only what needs to be opened.

Our techs work on every pipe material found in Cresskill, NJ homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.
Acoustic detection is most effective on pressurized supply lines. Combined with a pressure test to confirm water loss before we start, it tells us both that there's a leak and exactly where it is.
We use thermal imaging as a complement to acoustic detection โ particularly useful for slab leaks and leaks inside insulated wall cavities where sound transmission is reduced.
Our techs are proficient in copper sweating (soldering), press-fit connections (ProPress system), CPVC solvent welding, PEX crimp and expansion fitting installation, threaded galvanized repair, and ABS/PVC drain line work. We match the repair method and material to the existing pipe system rather than forcing incompatible transitions.
Drain line repairs are water-tested by running fixtures through the repaired section and visually confirming no seepage at the repair joint and downstream.
From a pinhole copper leak behind a kitchen cabinet to a full galvanized repiping, our pipe crew in Cresskill, NJ handles the full range.
Pitting corrosion in copper is sometimes systemic rather than localized โ a single pinhole is often the first of several to appear. When the camera or pressure test finds multiple deteriorated sections, we give you an honest assessment of whether targeted repair or full copper repipe is the better long-term answer.
Galvanized steel pipe was standard in homes built before the 1960s. It corrodes from the inside out โ zinc coating depletes, iron oxide (rust) accumulates on the inner wall, progressively narrowing flow and leaching into the water supply. Repairs on severely corroded galvanized are generally temporary; the pipe is failing systemically along its full run.
PEX is also the material of choice for extending or reconfiguring supply runs during remodel work. Its flexibility reduces fitting count and eliminates the need for torch work inside walls.
We also inspect upstream of the burst for additional sections that froze but haven't yet failed โ because a partially-thawed line sometimes shows multiple failure points only after pressure is restored.
Slab leak rerouting is often more cost-effective than direct access, particularly for longer runs or under tiled floors. We present the options honestly with pricing so you can choose based on your priorities.
When galvanized supply lines are at end of life or polybutylene pipe (recalled for chronic failure) is in the home, a full repipe with PEX or copper is the permanent solution. We run new supply lines through the structure, transition all fixture connections, pressure test the entire new system, and patch access points in walls and ceilings.
Here's how a Masters Plumbing Service pipe repair call plays out in Cresskill, NJ.
Active leak? Our dispatcher walks you through shutting off the main supply valve while we drive to you. Describing what you see โ water stain on a ceiling, drop in water pressure, wet flooring โ helps us arrive with the right detection tools loaded.
This detection step routinely saves homeowners $500โ$2,000 in unnecessary drywall removal compared to opening walls speculatively.
For slab leaks, we present repair, reroute, and lining options with pricing so you can make an informed choice before any concrete is cut.
You receive a written summary of what failed, what we installed, and the warranty terms before we leave.

Water stain appeared on my kitchen ceiling from the bathroom above. I expected them to tear up the entire bathroom floor. Instead the tech ran a pressure test, found a 12% pressure drop over 10 minutes, then used the acoustic device and identified the leak at a failed sweat joint in the copper supply to the toilet โ accessible through a 14-inch drywall cut in the ceiling below. Repair was maybe $280 including the detection. I'd been dreading a $2,000 floor demo.
Had an under-slab leak diagnosed by Masters Plumbing Service with acoustic equipment. They found the leak at 6 feet from the wall โ a single copper elbow that had developed a pinhole. Presented three options: direct slab access, reroute through the wall framing above, or copper lining. I chose the reroute โ they ran a new PEX line through the crawl space and connected at both ends without touching the slab. Pressure tested, verified no remaining drop. No jackhammering at all.
