Slab Leak Repair and Replacement in Frisco, TX
Slab leak repair and replacement in Frisco starts with finding the leak. Frisco grew from a small town to one of the largest cities in North Texas in about 25 years, and almost every house is a recent slab on clay. A leak in a house that new is almost always one point failing, not a worn line. Call and we’ll connect you with a local crew.

A city built in a single generation
Frisco sits across Collin and Denton counties on Blackland clay. The old downtown is modest. Nearly everything else was built from the late 1990s on, in big subdivisions of one- and two-story homes on post-tensioned slabs. That age profile is the opposite of the 1960s copper neighborhoods farther south, and it changes what a leak typically turns out to be.
In a house under about 25 years old, supply lines are almost always PEX, a flexible plastic that runs in long unbroken lengths with fewer joints than copper. Wear along the pipe is unusual. What fails is a connection: a fitting that was not fully seated, a crimp ring that sat slightly off, or a line pinched or nicked while framers worked around it.
Signs to watch for
Because PEX seldom seeps, a leak in a more recent home tends to be sudden rather than gradual. A bill may jump in one cycle instead of creeping. A warm patch may appear on a floor in a few days. Some owners first hear a faint hiss in a quiet house or notice the water heater running through the night.
None of these signs says the leak is under the slab. Irrigation, a running toilet and a stuck outdoor tap can look the same on a bill. The five-minute meter check is how those get separated. See water meter leak check.
A local crew describes what happens next.
Pressure regulators and why they matter
Most Frisco homes have a pressure-reducing valve close to the main shutoff, since city supply pressure is higher than fixtures are rated for. When that valve drifts or fails, pressure in the house climbs. Fittings, hoses and water heater connections next carry loads they were not meant to.
A technician can check pressure with a gauge on a hose bib in a minute or two. High pressure does not prove a leak, but it is one of the first things worth ruling in or out in a more recent home that has leaked once, since a second fitting may be next in line.
Builder warranties and who to call first
Many Frisco houses are inside the window where a builder or a third-party plan still covers plumbing, at least in part. Terms vary a great deal in what they cover, how long and what must be done before work starts. Read yours before anyone opens a floor. Calling the builder as well as us is sensible while a warranty may apply.
A technician can locate and document the leak. That record is useful when you talk to a builder, and this site does not advise on warranties.
How the leak is found
The method is the same as in an older home, and it tends to work well on PEX. The technician isolates the hot and cold sides by closing valves and watching the meter. The suspect line is pressure tested and observed on a gauge. Acoustic equipment listens along the floor for the hiss of escaping water, and thermal imaging can show a warm path on the hot side.
Long unbroken PEX runs help here, since they leave only a handful of places where a leak can be. That narrows the search. See how slab leaks are found.

Spot repair is widespread in more recent homes
When a leak is a single fitting, a spot repair through the slab can be the easiest answer: open the floor at the located point, replace the fitting or section, and close it. Rerouting through the attic is the alternative where the leak sits under finished tile or cabinetry. The technician explains which is practical.
Flooring contractors handle surfaces and restoration companies handle drying, and this site does not do either. See slab leak repair.
Describe what you have already turned off.
Pools, irrigation and outdoor lines
Frisco lots frequently have irrigation controllers, drip zones and outdoor kitchens or pool fill lines. Any of them can move the meter. A technician rules those out before looking at the slab. See pool and irrigation leaks vs. slab leaks. This site does not repair pools or irrigation.

Newer Frisco homes and how leaks show up
Most of Frisco was built after the late 1990s, and many neighborhoods are less than twenty years old. Subdivisions such as Starwood, Panther Creek and the areas around Stonebriar were developed in phases, so two streets a mile apart can have houses built ten years apart. Nearly all newer Frisco homes use PEX supply lines rather than copper, often run through the attic and walls with only part of the plumbing under the slab.
PEX does not wear the way copper does. When a newer Frisco home leaks under the floor, it is usually at a single fitting, a damaged section from construction or a nail or screw from later work. That makes the leak easier to isolate but harder to predict. Frisco homes often have a pressure regulator near where the line enters the house, and a failed regulator can raise pressure enough to stress fittings, so the technician may check it.
Frisco buys treated water from a regional supplier, and the city handles meters and billing. Many homes here are still within builder warranty windows. Find the warranty paperwork and the builder contact before you call, because the builder may want to be involved. The soil is Blackland Prairie clay, which moves a great deal, and new slabs settle in their first years. Irrigation systems are standard, so close the irrigation valve before the meter check.

What Frisco homeowners ask about slab leaks
A leak is one possible reason. Irrigation and a running toilet are others, and the Frisco meter check helps separate them. A hidden leak shows first on the usage line. For newer homes in Frisco, a moving dial with everything off is the clearest early sign.
In Frisco, it depends on the terms. Check what your warranty covers and call the builder as well. A technician can locate and document the leak, and this site does not advise on warranties. Mention any earlier leak in the Frisco home when you call.

Isolation, pressure testing, acoustic listening and thermal imaging. Long runs help narrow it.
It lowers supply pressure to a safe level inside the home. If it fails, fittings carry more load.
No. In Frisco, isolation, pressure tests, acoustic listening and thermal imaging narrow the search before anything is opened, though the result is not always one exact point. A Denton County crew can tell you how long the visit is likely to take.
No. A foundation contractor handles that question. A technician explains what applies to the house after locating the leak.
PEX most commonly fails at a single fitting or a spot damaged during construction, not from wear.
Yes. Slabs on clay move seasonally, and PEX flexes with that.
