Pinpoint Leak Detection in Round Rock, TX
A confirmed leak and a precisely located leak are two different things. Knowing which pipe and which zone is losing water is the start. Knowing the inch-accurate point on the floor or wall is what determines whether the repair opening is four inches or forty.
Why precision changes the repair cost
The most expensive part of a slab or in-wall leak is often not the pipe repair itself but the surface work around it. That means tile or flooring removed, concrete cored or chipped, drywall replaced. That cost scales directly with the size of the opening. An inch-accurate locate means a four-inch core above the exact point. An approximate locate means a row of cores marching across the floor until the technician hits the right one. The time, the material, and the finish work are all multiples of each other.
In Round Rock homes with original tile floors or high-end finishes, the homeowner's first concern is often not the plumbing but what the plumbing is going to cost in surface damage.
The tools that give inch accuracy
Pinpointing draws on the full suite of detection methods but uses each one differently. Acoustic correlation gives a pipe-path distance from the nearest access point. A helium sensor swept over the confirmed zone reads a sharp concentration peak with a few inches of uncertainty. An ultrasonic contact probe on the slab or wall surface produces a signal that peaks directly above the leak. Thermal imaging shows the wet area but not the leak source within it. We combine two or three of these confirmations on a small area, and where they agree, that is where the core goes.
If a prior locate gave you a zone but not a spot, call (512) 737-6168 and we can work that zone down to an exact location.
The confirming dye test
For slab leaks where acoustic work has narrowed the location to a small area, a dye test through the system can confirm which line is losing water. It can also confirm the approximate surface location of the exit point. The dye exits the pipe at the break, follows the water path through the slab, and eventually surfaces where the concrete is already damp. Finding the dye at a specific surface point after a controlled run confirms what the instruments showed. Two independent confirmations at the same spot is the standard we work toward before the core saw runs.
Pinpointing in walls and ceilings
For in-wall and in-ceiling leaks, pinpointing means arriving at a location specific enough to mark a single access cut rather than opening a search section. An ultrasonic probe peaking at a specific stud bay and a thermal camera showing a wet zone in one framing cavity narrow the area considerably. A moisture meter confirms the stud location. Together they mark a small rectangle on the wall. That rectangle is rarely larger than a standard drywall patch. That is the size of the hole that gets cut; the rest of the wall stays intact.
What a proper pinpoint protects
Precision location protects the homeowner in two directions at once. It keeps the surface damage small, which reduces the restoration cost and the disruption to the home. And it prevents the cost of a second or third core because the first one was close but not exact. Missed coring on a slab, especially when the pipe turns or the signal refracted through the concrete, is one of the more frustrating and expensive outcomes of an imprecise locate. The goal of every pinpoint job is one accurate core, one repair, and one patch. Call (512) 737-6168 when inch accuracy matters before a core or cut.

📞 (512) 737-6168Frequently Asked Questions
How small can the opening be if the leak is pinpointed accurately?
On a slab, a single four-inch core above the exact location is often enough to expose the pipe and make the repair. The difference from an approximate locate can be the difference between one core and a row of them.
What if the acoustic and thermal results disagree?
We add a third confirmation rather than guessing between the two. Helium at peak concentration, an ultrasonic contact check, or a dye test in the line can resolve disagreement between the instruments.
Can you pinpoint a leak in a finished bathroom?
Yes. Ultrasonic and thermal methods work through tile and drywall without touching the finish. We mark the access cut on the surface before any tile is removed, so the opening is planned rather than exploratory.
