Dallas-Fort Worth
Areas We Cover in Dallas-Fort Worth
North Texas is where slab leaks are most common and most often repeated. The clay moves, the copper is decades old, and many homes are on their second or third leak. Call and we’ll connect you with a local crew that works on these slabs every day. We connect callers across Dallas-Fort Worth with local crews for slab leak repair and replacement.

Clay that swells, shrinks and moves the slab
Much of North Texas sits on Blackland and other expansive clays. After rain the clay takes on water and swells. In a long dry stretch it shrinks and cracks. A concrete slab floats on that moving ground, and the water lines poured into or beneath it move with it, a little at a time, for years.
Copper is stiff. Where a line bends, passes through the slab edge or lies against gravel, repeated small movement can wear the pipe wall from the outside until a pinhole opens. That is why many DFW leaks are found at the same kinds of places: elbows, tees, and runs that cross the slab near the water heater or the kitchen.
Soil movement is background, not a diagnosis. A leak does not mean a foundation has failed, and this site does not assess foundations. If you also see wide cracks or doors that stick, a foundation contractor is the right call for that question.
Copper under the slab in 1960s-1990s homes
Mesquite, Garland, Irving, Grand Prairie, Arlington, Richardson, North Richland Hills, Euless and many other DFW cities grew quickly from the 1960s through the 1990s. Homes of that period were commonly built on slabs with copper supply lines routed beneath the concrete. The pipe was sound when it went in. After several decades of soil movement and water chemistry, some of it is now leaking.
A technician confirms what a particular home has. We can say only that homes of this age sometimes have copper under the slab and that leaks in them are common enough that a first, second or third repair is not unusual.
Many owners of these houses ask about copper pipe leaks under the slab and about repeat slab leaks after a first repair. Both pages walk through what usually steers the next decision.

Polybutylene-era and newer PEX homes
Homes built from roughly the late 1970s to the mid-1990s may have polybutylene supply lines, a gray or blue plastic that was widely used for a time. A technician confirms whether a home has it. These lines tend to fail at fittings rather than along the pipe, and that affects how a leak is located and what repairs are discussed.
Newer subdivisions in Frisco, Prosper, Celina, Forney and Mansfield mostly use PEX. PEX flexes with ground movement better than copper and has fewer joints under the slab, but it can still leak at a fitting or be damaged during construction. A newer house with a leak is less likely to be a wear problem and more likely to be a single point failure.
See polybutylene-era homes and PEX slab leaks for the plain-language version.
Mature trees and uneven soil
Established neighborhoods across Dallas, Tarrant and Collin counties have large oaks, elms and pecans close to the house. Roots draw moisture from the soil unevenly. One side of a slab can dry faster than the other, and that difference adds to the movement that stresses lines beneath. The effect is gradual and varies from lot to lot, so it is one factor among several rather than a cause anyone can point to from the street.

How the region is organized
DFW is not one market. Dallas County, Tarrant County, the Collin and Denton county suburbs, Rockwall and Kaufman County to the east, and Ellis, Johnson and Parker counties to the south and west each have their own mix of building years and ground. Dallas and Fort Worth are large enough that each gets its own hub and area pages, and Arlington has a long page of its own. Every other city below has a page as well.
The list on this page names every DFW community we cover. If yours is not linked yet, call and we will still connect you with a crew that serves it.
A local crew explains what happens next.
What to do first
Turn off everything that uses water and look at the water meter. If the leak indicator or dial is moving, water is escaping somewhere on the property. That is the only diagnostic step to try yourself, and it does not tell you the leak is under the slab. The steps are on the water meter leak check page.
If water is surfacing, shut off the main if you can reach it safely, keep people and pets away from wet areas, move valuables, and call. Stay clear of outlets and appliances near standing water. If anyone smells gas, leave the house and call the gas utility and emergency services from outside.

Is it a slab leak?
What homeowners in Dallas-Fort Worth notice first
- SIGN 01
Warm spot on the floor
Common in DFW ranch homes with the water heater at one end. A warm patch often follows the hot line across the slab.
- SIGN 02
Water bill jumped
A bill that doubles with no change in use is one of the most frequent calls from Collin, Denton and Tarrant counties.
- SIGN 03
Running water at night
In a quiet 1970s house, a faint hiss from the floor at 2 a.m. is easy to hear and easy to ignore.
- SIGN 04
Damp floor or lifting tile
Water spreading under tile or wood can show up at a baseboard far from the actual leak.
- SIGN 05
Water heater never rests
A hot-side leak keeps the heater refilling and reheating, and the gas or power use shows it.
- SIGN 06
Meter moving, fixtures off
The meter check is the first step anyone can take. It shows a leak exists, not where it is.

Questions about slab leaks in Dallas-Fort Worth
Expansive clay moves the slab through wet and dry seasons, and many homes from the 1960s to 1990s have copper lines under the concrete. Years of small movement can wear the pipe at bends and joints. Newer homes can leak too, usually at a single fitting.
Yes. Newer homes usually have PEX, which handles movement better than copper. Leaks tend to occur at a fitting or where a line was damaged during building, and they are less likely to be a general wear problem.
A warm spot that stays warm when the heating is off and the sun is not on it can point to a hot-water line. Only a technician can confirm the cause, and locating the leak comes before any floor is opened.
No. A leak is a plumbing problem. Foundation condition is a separate question handled by foundation contractors, and this site does not assess it.
Not necessarily, but houses with older copper under the slab often do have repeat leaks. After a second leak, a technician may talk through rerouting lines above the slab or repiping. Nothing is promised either way.
Yes. We cover Dallas, Tarrant, Collin, Denton, Rockwall, Kaufman, Ellis, Johnson, Parker and surrounding counties. Call from anywhere in the region and we will connect you with a local crew.
What you noticed first, whether the meter moves with everything off, roughly when the house was built, whether there has been a slab leak before, and whether water is surfacing now.
Roots pull moisture from the soil unevenly, which adds to ground movement around a slab. That can be one factor in line wear, but a technician has to locate the leak to say what happened in a particular house.
Find the leak before the floor is opened
Call and we’ll connect you with a local DFW crew that uses acoustic, thermal and pressure-testing equipment.
