01Slab leak signs
These are common signs of a leak beneath a concrete floor. On-site testing narrows down exactly where the line has failed.
A hot-water line leaking under the slab warms the concrete above it. It is one of the clearest signs of a slab leak.
Moisture coming through a slab or at its edges means a line beneath it has failed. Locating it precisely keeps the repair small.
A hot line leaking under the slab keeps the heater working to replace what escapes. The bill usually rises with it.
02History matters
A first slab leak and a third one are not the same problem, even when the fix looks similar.
One failure on an otherwise sound line is often a single weak point: a joint, a bend, or a spot where the pipe was nicked during the original install. Repairing that one section is usually enough, and the rest of the line can be expected to hold.
A pipe that has already failed once under the same slab is more likely to fail again nearby, especially on an older line or one made of a material prone to corrosion. At that point, a plumber weighs whether another isolated repair is worth it or whether the line itself has reached the end of its life.
None of this locates the leak. It limits what running water does in the meantime.
Close the main shutoff, since a line under a slab usually has no separate valve of its own. Stopping the flow keeps a slab leak from growing while repair options are worked out.
If a warm spot points to a hot line leaking below, turning off the water heater stops it from working to replace what keeps escaping, and eases the strain on the system until the line is repaired.
Tile, hardwood, carpet, and cabinetry above the affected area all change how it gets reached. Noting what is there before the visit helps a plumber plan the opening and coordinate with any other trade the repair involves.

03The repair decision
The right fix for a slab leak is not the same for every property. These are what a plumber weighs.
Copper and galvanized steel both weaken with age, and a line that is decades old is a different case from one installed in the last few years. An older line failing once is a reason to look closely at the rest of it.
Carpet and vinyl are simple to lift and replace. Tile, hardwood and finished cabinetry cost more to remove and restore, and that cost is part of deciding whether to open the floor or route the line around it instead.
A leak confined to a short section is a smaller job than corrosion or scale running along most of a pipe's length, which changes how much of the slab or the run needs to be reached.
04The repair options
Which one fits depends on the pipe's age, how many leaks there have been, and what sits above it.
The plumber opens a small section of the slab or floor right at the located failure, replaces the damaged length of pipe, and closes it back up. It suits a single failure on a line that is otherwise sound.
Instead of opening the slab, the plumber runs a new length of pipe overhead through the attic or walls, or around the perimeter, and connects it in at both ends. The slab stays untouched, at the cost of a longer run of new pipe.
When a line has failed more than once, or is old enough that further failures are likely, replacing the whole run costs more upfront but avoids repeat openings into the same slab. Repiping can run through the same access created for a spot repair or through new access, depending on the layout.
05Getting to it
Reaching a line under a slab means cutting through whatever is on top of it first: a section of flooring, then a section of the concrete itself, sized to the small area the leak was narrowed down to rather than the whole floor. Tile and hardwood are cut and set aside where they can be reused; carpet and vinyl are usually replaced outright once the work underneath is done.
Once the pipe is reached and the repair is made, the concrete is patched and the flooring restored, so the finished floor is the last part of the job rather than the first. Coordinating that restoration, especially with tile or cabinetry that has to be reset exactly, is often as much a part of the job as the plumbing itself.
06Questions
By listening for it and pressure-testing the lines. Acoustic equipment narrows the location to a small area, so the repair opens only what it has to, or the line is rerouted above the slab and the floor stays intact.
Water that cannot be stopped, sewage coming up, no water at all, or a smell of gas: urgent. A drip, a slow drain or a running toilet: worth fixing soon, but not tonight. When in doubt, shut off the water to the fixture and ask.
If water is actively leaking, yes: the fixture’s own valve, or the main if it doesn’t have one. A slow drip can wait, but a bucket under it will not hurt.
A pipe that has already failed once under a slab is more likely to fail again nearby, especially if it is old or made of a material prone to corrosion. Replacing the whole run avoids opening the same slab repeatedly, though it costs more than a single spot repair up front.
Instead of opening the slab, the plumber runs a new length of pipe overhead or around the perimeter and reconnects it at both ends, leaving the original section disconnected and the slab untouched. It typically uses more pipe and labor than a spot repair, but avoids cutting into the floor.
Where the problem is, when it started, what changed, whether the water is off, and the age of the fixture or heater involved. A photo of the problem and of any visible model label helps too.
