Leak Detection Services
When you know you have a leak but don’t know where it is, finding the source is the first step toward stopping the damage. Hardenburgh Plumbing provides water leak detection to locate hidden plumbing leaks behind walls, above ceilings, beneath the ground, and in other hard-to-reach areas. We use specialized equipment to narrow down the source without relying on guesswork or unnecessarily opening walls or digging up your property.
Since 1989, Hardenburgh Plumbing has helped homeowners throughout Palm Beach County solve plumbing problems, including difficult-to-find leaks. A licensed master plumber handles the work, using acoustic listening equipment, electronic line locating, thermal imaging, and plumbing experience to determine where the water is coming from and what needs to happen next.
Better yet, we don’t stop once we find the leak. Hardenburgh Plumbing can make the necessary plumbing repair, so you don’t have to find another contractor to finish the job.
If unexplained water use, damp areas, or other warning signs have you searching for a hidden leak, call Hardenburgh Plumbing at 561-968-0000 to schedule leak detection service.


How Professional Water Leak Detection Finds the Source
A hidden leak rarely provides a convenient trail straight to the damaged pipe. Water can travel along pipes, framing, drywall, or other materials before it becomes visible. That means the wet spot you see isn’t necessarily where the plumbing actually failed.
Professional leak detection is about narrowing down the problem before making a repair. Depending on the location and type of leak, Hardenburgh Plumbing may use several methods to identify the source.
Acoustic Listening Equipment
Water escaping from a pressurized pipe creates sound and vibration. Acoustic listening equipment helps a plumber listen for those sounds through surfaces where the pipe itself isn’t visible.
By comparing sound at different locations, the plumber can narrow down where water is escaping. This can be especially useful when a supply line is buried or otherwise inaccessible.
Electronic Line Locating
Before you can pinpoint a leak in a concealed or underground line, you need to understand where that line runs. Electronic line locating equipment helps trace the path of piping that can’t be followed visually.
Knowing the route of the line gives the plumber a more focused area to investigate and can reduce unnecessary digging or opening of finished surfaces.
Thermal Imaging
A plumbing leak can sometimes change the temperature of surrounding materials. Thermal imaging allows a plumber to look for temperature differences that may indicate water or moisture behind a wall, ceiling, or other surface.
Thermal imaging doesn’t require tearing into the surface just to begin investigating. When used alongside other diagnostic methods, it can help narrow down the location that needs closer attention.
No single tool is right for every leak. The plumber considers what you’re seeing, where the plumbing runs, and the results of the diagnostic equipment to determine the most likely source.
Underground Leak Detection Without Guessing Where to Dig
An underground water leak can be especially frustrating because there may be no exposed pipe or obvious break to inspect. You might notice an unusually wet area outside, unexplained water use, or signs that water is escaping somewhere between the meter and your home.
Hardenburgh Plumbing provides underground leak detection for water lines that can’t be visually inspected. Electronic line locating can help establish the path of a buried line, while acoustic equipment can help narrow down where water may be escaping.
Underground leaks can occur in several places around a property, including:
- Water service lines: A leak can develop in the buried line running between the water meter and the house.
- Irrigation lines: Leaks in buried irrigation plumbing can release water underground before the problem becomes obvious at the surface.
- Pool lines: Pool plumbing can also develop concealed leaks that require careful investigation to locate.
The goal is to identify the problem area as precisely as possible before excavation or repair begins. That means less guesswork about where the pipe is located and where access may be needed.

Finding Leaks Behind Walls and Ceilings
A stain on the ceiling or damp drywall tells you water has reached that location. It doesn’t necessarily tell you where the leak started.
Water can move away from a damaged pipe before soaking through a visible surface. Cutting directly into the first wet spot can therefore mean opening the wrong area.
Hardenburgh Plumbing uses diagnostic equipment and plumbing knowledge to trace the problem back toward its source. Thermal imaging may help identify temperature changes or moisture patterns behind finished surfaces, while other testing can help determine which plumbing line is involved.
Once the source has been narrowed down, the plumber can determine where access is actually needed to make the repair.
Pinhole Leaks in Aging Copper Pipes
A small pinhole leak in a copper water line can create a surprisingly large problem when it occurs inside a wall or ceiling. Because the opening is small, the leak may continue unnoticed until staining, dampness, or other water damage becomes visible.
Finding and repairing an isolated pinhole leak may solve the immediate problem. Repeated leaks, however, can be a reason to look more closely at the condition of the plumbing system rather than treating each new leak as an unrelated repair.
If an older copper system is developing recurring leaks, Hardenburgh Plumbing can discuss whether continued spot repairs make sense or whether repiping and pipe replacement should be considered.

What About a Leak Under the Slab?
Leaks beneath a concrete foundation require their own diagnostic and repair approach. Hardenburgh Plumbing provides dedicated slab leak detection and repair for plumbing problems beneath the foundation.
If the signs point to a slab leak, the focus shifts to locating the affected line and determining an appropriate repair strategy for that specific situation.
We Find the Leak and Repair It
Some leak detection services end with a location. You’re told where the problem probably is, and then you have to call someone else to repair the plumbing.
Hardenburgh Plumbing handles both sides of the problem.
Once the leak has been located, your plumber can assess the damaged pipe, explain the repair options, and complete the plumbing work needed to stop the leak. That continuity matters because the same plumbing company that investigated the problem understands what was found, where it was found, and how the surrounding system is configured.
It also means you can move directly from diagnosis to a solution instead of starting over with another contractor.
Water Leak Detection FAQs
Unexplained increases in water use, damp drywall, ceiling stains, wet areas outside, or the sound of water when fixtures aren’t running can all justify further investigation. The exact signs depend on where the leaking pipe is located.
Not necessarily. Acoustic equipment, electronic line locating, and thermal imaging can help narrow down a hidden leak before access is created. Some repairs will still require access to the damaged pipe, but leak detection can help determine where that access should be made.
Yes. Hardenburgh Plumbing provides underground leak detection for buried water service lines, including lines between the meter and the home.
Yes. Hardenburgh Plumbing is a plumbing contractor, not a locate-only service. Once the leak is identified, we can determine the appropriate plumbing repair and complete the work.
