Pipe failures range from a slow pinhole leak weeping inside a wall to a full main line rupture. Locating the failure precisely β before opening drywall or digging β is the skill that separates a clean, affordable repair from an expensive and destructive guessing operation. Masters Plumbing Service's pipe technicians in Naperville, IL 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 Naperville, IL homes, from pre-1970s galvanized to modern PEX-A crosslinked systems. The repair method matches the pipe.
Pressurized water escaping a pipe creates a characteristic acoustic signature. Our listening devices amplify ground and structure-borne sound to pinpoint a leak location within inches β through concrete slabs, behind drywall, or under flooring. This means we open only the section of wall, floor, or slab directly over the failure.
Active water leaks create temperature differentials on wall and floor surfaces detectable with an infrared camera. A slow leak inside a wall shows as a cold, spreading zone; a hot water line leak shows the inverse. Thermal imaging confirms leak presence and approximate location before any cutting begins.
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 Naperville, IL handles the full range.
Pitting corrosion in copper is sometimes systemic rather than localized β 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.
We replace galvanized supply lines with copper or PEX β either as targeted section replacement at active failure points or as a full-house repipe project. We connect the new material to existing fittings using dielectric unions where code requires to prevent galvanic corrosion at copper-to-galvanized transitions.
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 β 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.
A full repipe in Naperville typically completes in 2β3 days for a standard single-family home. You're without water for a portion of each day; we plan the schedule to minimize disruption to occupied rooms.
Here's how a Masters Plumbing Service pipe repair call plays out in Naperville, IL.
For emergency burst pipe calls, we dispatch immediately. For suspected slow leaks, we schedule at the earliest available slot and confirm before arrival.
We pressurize the supply system and monitor for pressure drop to confirm an active leak. Then acoustic listening devices and the thermal camera locate the failure to within a small area β telling us which section of wall, floor, or slab to open.
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.

My older home had a copper supply line fail inside an exterior wall. The thermal camera showed the wet zone through the drywall without any cutting. They opened a 10-inch section right at the pinhole, put in a press-fit repair coupling β no torch in my wall β pressure tested, and patched the drywall themselves. Two hours total.
Had an under-slab leak diagnosed by Masters Plumbing Service with acoustic equipment. They found the leak at 6 feet from the wall β 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 β 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.
I noticed my water meter spinning with all fixtures off β confirmed a leak in the supply system. Masters Plumbing Service ran a pressure test and acoustic scan, found a pinhole in a copper section under the slab in the utility room. They rerouted the line through the wall above slab, tested, and closed out the permit. The reroute was exactly the same cost as direct slab access would have been, but no damaged floor tile.
