A water pipe leaking under your concrete floor doesn’t stop on its own, and every hour it runs it soaks the soil under your foundation. Target Plumbers finds slab leaks with listening and pressure-testing equipment, marks the spot on the floor, and gives you the choices: open the slab at one point, reroute the line above the floor, or repipe if the old copper is failing everywhere.
You can check for a hidden leak yourself before you call:
| What you notice | What it usually means | How soon to act |
|---|---|---|
| A warm or hot patch on tile or wood floor | The hot-water line is leaking under that area | Soon: you’re also paying to heat the lost water |
| Sound of running water with every fixture off | Pressurized water escaping under the slab or in a wall | Soon |
| Water bill up without a change in use | A steady leak somewhere; the meter test narrows it down | Within days |
| Damp carpet, lifting laminate or a musty smell in one room | Water wicking up through the slab | Now: risk of mold and floor damage |
| Water heater running constantly | Hot water leaking out and being replaced | Soon |
| New cracks in floor tile or the slab | Long-running leak washing out soil under the foundation | Now |
You get the location marked on the floor and a written repair quote.
| Repair | Best when | What happens to your floor |
|---|---|---|
| Spot repair through the slab | One leak, in an accessible spot, on pipe that is otherwise in good shape | A small section of flooring and concrete is opened, the pipe is repaired, the concrete is patched; the floor covering is restored separately |
| Reroute the line | The leaking run sits under finished floors or cabinets, or the pipe has leaked before | The old line under the slab is abandoned; a new line runs through walls or the attic. Floors stay intact; small wall openings are patched |
| Whole-house repipe | Repeated leaks or corroded copper throughout the house | All supply lines replaced above the slab, so the next leak can’t happen under the floor |
If more than one leak has already shown up, patching another spot often just moves the problem. We’ll tell you when rerouting or repiping is the better spend.
Leak in a drain or sewer line under the slab instead of a water line? That’s a different repair; see sewer line rerouting.
Policies differ, but many cover the cost of reaching the leak and the water damage it caused more readily than the pipe itself. Before the floor is opened:
This is general information, not coverage advice. Your policy and insurer decide what’s covered.
Unplanned repairs like this can be paid off over 48 months at 0% interest for customers who qualify.
The clearest signs are a warm spot on the floor, the sound of water running when nothing is on, and a water bill that climbs for no reason. The water-meter test on this page confirms whether water is leaving the system.
Yes. Locating and repairing water lines under the slab is plumbing work; we do both, and we patch the concrete. Finished flooring is usually restored by a flooring contractor.
It depends on how the leak is fixed. A single spot repair costs less than a reroute, and a reroute less than a whole-house repipe. The floor covering over the leak also matters. You get a written price after the leak is located.
If this is your first leak and the pipe looks sound, a spot repair or short reroute is usually enough. If you’ve had two or more leaks, or the copper is corroded, a repipe stops the cycle.
It depends on your policy. Many policies treat access to the leak and resulting water damage differently from the pipe repair itself. Document the damage and contact your insurer before repairs begin.
A leak left running can wash out or swell the soil under the slab, which can lead to cracks and settling. Catching it early limits that risk.
Detection and a spot repair can often be done in a day or two. Reroutes and repipes take longer, depending on the size of the house.
If the floor is wet or you hear water running, yes: close the main shut-off and call (844) 941-2727. If it’s only a high bill, keep using water normally until we test the lines.
