What Is a Slab Leak, and When Do You Need Repair?
A slab leak is a break in a water supply line that runs through or under the concrete slab your home sits on, and slab leak repair locates that break and stops it. Most homes in Southwest Florida are built slab-on-grade, with copper or plastic water lines run beneath the floor, so this is a common plumbing call here.
You need plumbers for slab leak repair when water is escaping somewhere you can't see. The signs are usually indirect: a water meter that moves with every fixture off, a bill that climbs without a change in use, or a warm spot on the floor. The EPA's WaterSense guidance on finding household leaks walks through a simple meter check you can run yourself.
What's Included in Slab Leak Repair
- A water meter test to confirm there's a leak and measure how fast water is being lost
- Electronic leak detection, using acoustic listening equipment, thermal imaging and line pressure testing, to pinpoint the leak through the floor
- Spot repair: opening a small section of slab, repairing the pipe and patching the concrete
- Rerouting: abandoning the leaking section and running a new line through walls or the attic
- Whole-house repiping when the pipes are failing in more than one place
- Photos and written notes of what we found and what we did
- Where the job requires a permit, it's permitted
- Floor protectors and full cleanup after the work
Why Finding the Exact Leak Spot Matters
A slab leak can run for weeks before anyone notices, since the water goes into the soil instead of onto the floor. Meanwhile it raises the water bill and, on a hot side leak, keeps the water heater running.
Pinpointing the leak before cutting anything is what keeps the repair small. Accurate detection can be the difference between opening a small square of floor and tearing up a room.
The repair choice comes down to the pipe's overall condition. One pinhole in otherwise healthy pipe suits a spot repair. When a line has leaked before, or the leak sits under cabinets or expensive tile, rerouting it overhead often makes more sense. If several lines are wearing out, a whole-house repipe stops the pattern of repeat leaks.

Frequently asked questions
Plumbers who handle slab leak repair find leaks under concrete with electronic leak detection rather than guesswork. A meter test confirms the leak and shows whether it's on the hot or cold side. Acoustic listening equipment picks up the sound of escaping water through the floor, thermal imaging can show the heat from a hot water leak, and pressure testing confirms which line is affected. Together, these let the plumber open only a small section of floor, or none at all with a reroute.
The best slab leak repair depends on the condition of the pipe. A spot repair, where a small section of slab is opened and the pipe fixed, works well for a single leak in otherwise healthy pipe. A reroute abandons the leaking line and runs new pipe through walls or the attic, which avoids breaking the floor and is often smarter when a line has leaked before. A whole-house repipe makes sense when pipes are failing in several places.
The most reliable sign you need slab leak repair is a water meter that keeps moving when every fixture in the house is off. Other common signs include a warm spot on the floor, the sound of running water when nothing is on, a rising water bill, damp carpet or swollen baseboards, and a water heater that runs far more than usual. Any one of these is worth checking, and two or more together point strongly to a leak under the slab.
Whether insurance covers slab leak repair depends entirely on your policy, so the only reliable answer comes from your insurer. Policies often treat the pipe repair and any resulting water damage differently. What helps any claim is clear documentation: photos of the leak location, notes on how it was found and what was repaired, and an itemized invoice. Ask your plumber for that paperwork and call your insurance company before or early in the repair.
What Affects the Cost of Slab Leak Repair
- How long it takes to locate the leak and how many leaks there are
- Repair method: spot repair, reroute or whole-house repipe
- Where the leak sits, such as under tile, cabinets or an open floor
- Pipe material and size, and the age of the rest of the plumbing
- How far a reroute has to travel through walls or the attic
- Permit requirements for the work
Finished flooring over a spot repair, like tile or wood, is typically a separate job. You'll get upfront pricing for the plumbing work before anything starts.
