Slab Leak

A slab leak doesn't stay contained to one spot; the longer it runs under the foundation, the more it can undermine the floor and the structure above it.

When this becomes an emergency

What a pro does

Slab leaks are close to a signature Treasure Coast plumbing problem, since most homes here sit on a concrete slab with the supply lines run directly through or under it rather than up through a basement or crawlspace. A plumber uses acoustic listening equipment and sometimes a thermal camera to pinpoint the leak's location under the floor before anything gets cut into, since guessing wrong on a slab means cutting concrete for nothing. Once the spot's confirmed, the repair itself might mean accessing that one section of slab directly, or in some cases rerouting the line entirely through the attic or an exterior wall to avoid the slab altogether. Copper pipe run in the 1970s and 80s is usually the culprit; decades against the ground and the slab itself eventually pit it through.

Frequently asked questions

A jump in the water bill with no obvious cause, combined with a warm patch on the floor or the sound of running water when everything's off, points strongly toward a slab leak rather than a visible pipe issue. A plumber confirms it with listening equipment rather than guessing from those signs alone, since cutting into a slab on a hunch is a costly way to be wrong.
Not usually. Most slab leak repairs target the one section of slab directly above the leak, which keeps the disruption to a single room or a small area of flooring rather than the whole house. Rerouting the line above the slab instead of through it is another option when the location makes direct access difficult.
Local construction is the main reason: most Treasure Coast homes are built slab-on-grade rather than over a basement or crawlspace, so the copper supply lines run directly through or under the concrete. Decades of contact with damp soil and the slab itself wear through that copper eventually, especially in homes built before PEX became standard.
