A slab leak rarely announces itself with a burst or a flood. It shows up as a warm patch on the floor near the edge of a room, a water bill that's climbed for no obvious reason, or a faint sound of running water when every fixture in the house is off. We trace the leak to its exact location with electronic detection equipment before recommending any repair, so a homeowner isn't paying for exploratory demolition across a slab to find something a listening device could pinpoint in an hour.
Acoustic and pressure equipment locates the leak before any cutting starts.
A precise location keeps the eventual repair small and targeted.
Specific familiarity with how Franklin's slab-built subdivisions develop these leaks.
One flat quote for the repair once the leak location is confirmed.
Franklin's karst-clay soil shifts with seasonal moisture, and that movement puts real, repeated stress on copper or galvanized supply lines running beneath a slab foundation. It's a genuinely common issue in the city's 1990s-2010s subdivisions specifically, where concrete-slab construction sits on the same shifting ground discussed throughout this site, and it shows up regardless of whether the home is a decade old or older.
Common SignsA strong sign of a hot water line leaking under the slab.
Often the very first sign, before anything is visible in the house.
Audible flow even with every fixture closed.
A leak diverting pressure before it reaches that tap.
We'll pinpoint the leak before anyone starts cutting.
This is the question we hear most on these calls, usually phrased as "I have a leak somewhere but I don't know where it's coming from." The combination that points most clearly to a slab leak is a rising water bill plus a specific warm or damp spot on the floor, particularly near where a hot water line would run. Not every unexplained bill increase is a slab leak, a running toilet or an irrigation line left on can look similar, so we rule out the easy explanations first. When those don't account for it, electronic detection narrows the leak to a precise spot before anyone starts cutting into flooring.
ProcessCheck toilets, irrigation, and visible fixtures before assuming the slab.
Acoustic and pressure equipment narrows the leak to an exact spot.
A precise location means an accurate repair price, not a range.
Targeted access and repair, minimal demolition.
This is one of the more common calls we get from Franklin's newer subdivisions built from the 1990s through the 2010s, where slab construction sits directly on the same shifting clay-limestone soil discussed throughout this site. It's not a sign of poor construction. It's a predictable outcome of building on this specific ground, and catching the early signs, the warm spot, the climbing bill, before it becomes a bigger repair is mostly a matter of knowing what to watch for.
Copper lines under a slab tend to develop pinhole leaks at a specific weak point rather than failing along their whole length, which is part of why precise detection matters so much here. A homeowner who's had one slab leak repaired sometimes assumes the whole line is compromised and starts planning a full repipe, when in many cases the rest of the copper run is sound and a targeted repair is the more honest recommendation.
FAQsIt's rarely sudden, but it worsens steadily and can eventually stress the foundation. Worth addressing promptly once suspected, not necessarily a same-hour emergency.
We quote detection and repair as connected steps, with the final repair price confirmed once the leak location is known.
In most cases, yes. Precise detection is what keeps the repair small and targeted instead of an exploratory cut.
Coverage varies by policy and cause. Sudden failures are sometimes covered, gradual ones often are not. Check your specific policy.
