Locating the leak precisely
Electronic listening and pressure isolation pin the leak down to a small area of floor, which is what keeps the repair contained.
Slab Leak Repair
Carrollton houses sit on concrete slabs, and a failed supply line underneath is a specific kind of problem. An independent plumber can locate the leak and explain repair options before concrete is opened.

Signs That Need Attention
- A warm or hot patch on a tile or vinyl floor
- The sound of running water when everything is switched off
- Cracked or lifting flooring in one part of the house
- Damp carpet at the edge of a room with no fixture nearby
The Blackland Prairie clay under Carrollton swells when it is wet and shrinks in a dry summer, and that movement works on copper lines cast into or run beneath the slab. It is also why a slab leak left alone can start affecting the foundation itself.
What a Provider May Assess
Not every problem needs all of this. Ask the independent provider which work is needed and which is optional.
Reviewing the repair options
Opening the slab at that spot, rerouting the line overhead, or replacing a whole run. Each suits a different house, and the trade-offs are explained on site.
Protecting the rest of the house
The work area is contained, the line is pressure tested afterwards, and the other supply runs are checked so a second leak is not left behind.
Your Repair Options
A single pinhole in an otherwise sound copper line can be repaired at the spot. A line that has already leaked more than once is usually rerouted, because reopening the slab repeatedly costs more than replacing the run. Ask the independent provider to quote the options that suit your property.
If you are not yet sure the leak is under the slab, start with leak detection. If a line has already split open, see burst pipe repair, and the repair versus replacement guide shows how the same judgment is made on a heater.
Slab leak work is arranged around Carrollton, including The Colony. Full coverage is on the service areas page.
Slab Leak Repair Questions
How do I know if it is a slab leak and not something else?
A warm floor, running water with taps off and unexplained damp are the usual signs, but only a proper location test confirms it. An independent plumber can use meter checks and listening equipment to assess the source.
What affects the cost of a slab leak repair?
Where the leak sits, the flooring above it, and whether the line is repaired in place or rerouted. All of that is established at the inspection and quoted before any concrete is cut.
Can a slab leak damage my foundation?
It can. Constant water changes the moisture in the clay under one part of the slab, and uneven soil moisture is what moves foundations in North Texas. That is the main reason not to wait.
Should I turn the water off while I wait?
If the leak is on the hot side, closing the cold inlet valve on the water heater slows it. Otherwise close the main at the meter box and open it only when you need water. See the slab leak guide.
