A slab leak is a leak in one of the water or sewer lines running underneath a home's concrete slab foundation. Because the pipe is buried under the floor, you won't see dripping water — you'll see the side effects instead: a warm spot on the floor, a spike in your water bill, or the sound of running water when every tap in the house is off.
Slab leaks are most common in homes built between 1960 and 1990, when copper supply lines were run directly through or under the slab. After 40-plus years, pinhole corrosion in that copper is the single most common cause we find. Homes with galvanized steel lines, or coastal homes where salt air accelerates corrosion on exterior fixtures, see it even earlier.
Any one of these on its own is worth a look. Two or more together, especially the warm spot plus the water bill jump, is worth calling about the same day.
We do not cut into the slab to go looking. Two non-invasive methods locate the leak first:
Sensitive listening equipment picks up the sound of water escaping under pressure through a pinhole or crack, and we triangulate the source along the pipe run.
A leaking hot-water line raises the surface temperature of the slab directly above it; a leaking cold-water line can do the opposite. Thermal imaging makes that temperature difference visible without opening anything up.
Used together, these two methods pinpoint the leak to a specific section of pipe before anyone picks up a tool, which is what keeps the repair itself to a small, targeted opening instead of jackhammering a whole room.
A single, isolated pinhole leak in an otherwise sound line is usually a spot repair: open a small section of slab, replace the failed segment, close it back up.
A repipe — rerouting the water line above the slab instead of patching it again — makes more sense when this is the second or third leak on the same line, the pipe is old galvanized steel or corroded copper throughout its run, the home has a history of pinhole leaks across multiple fixtures, or repeated spot repairs would end up costing more over a few years than one repipe.
We'll tell you which situation you're in and why, not just which one is more profitable for us.
Slab leak repair cost depends on where the leak is, how deep the slab is at that point, the pipe material, and whether it's a spot repair or a full repipe. We don't publish a flat number because a leak under a hallway and a leak under a load-bearing wall are not the same job — your free estimate, after the leak is located, is what gives you a real number for your situation. What we can tell you up front: non-invasive detection means you're not paying to open up slab you don't need opened, and getting a slab leak diagnosed early is consistently cheaper than waiting for it to spread to a second line or start affecting the foundation.
