Answered 24 hours a day, every day.

Soil under Flower Mound
Flower Mound is in Denton County close to Lewisville Lake. Houses date largely from the 1980s through the 2000s, many on big lots, on clay and prairie soils that move with moisture. Houses from the 1980s may have copper under the slab. Later homes use PEX. A technician confirms what a home has.
Long lines to the home
On a big lot the line from the meter to the house can be long. A leak in that run does not involve the slab and is generally repaired by digging in the yard. A technician checks it early with a pressure test between the meter and the home. A damp patch or unusually green strip along the line, or hissing at the meter box, are clues.
Shutting the home valve and watching the meter separates home from yard: if it still moves with the valve closed, the leak is on the yard side.
Describe what you have already turned off.
Irrigation and outdoor taps
Irrigation, pool fill lines and outdoor taps all move the meter. A technician rules them out first. See pool and irrigation leaks vs. slab leaks.
A local crew describes what happens next.
Newer PEX houses
PEX flexes with soil movement. A leak in a more recent home is more commonly at a fitting or a damaged spot than from wear. See PEX slab leaks.
Describe the signs you have seen.
What you can do today
Shut off every tap and water appliance, then watch the meter. If the dial turns, water is going somewhere on the Flower Mound property. If water is surfacing, shut off the main if you can reach it safely, keep people and pets away and call. For newer PEX-plumbed homes on expansive clay, this is one of the first things a crew asks about.

Before the crew reaches Flower Mound
A call from Flower Mound starts with three questions: the street or ZIP, what you have seen, and how long it has been going on. The answers shape the first visit. On a call from Flower Mound, expect questions about where the home is, what you noticed and when it began. That short conversation is how a Denton County crew decides what to bring.
It helps to know roughly when the house was built. Flower Mound homes from different decades often have different pipe under the slab, and that changes the test. Keep track of what you have tried, like closing valves or walking the yard. It saves time when the Denton County technician arrives.
Acoustic equipment picks up the sound of water escaping under pressure. A quiet house makes that listening easier, so a Flower Mound crew may ask you to pause appliances. On expansive clay, a crew may run more than one test, because moisture in the soil can spread away from the actual break.
If the leak is active and water is surfacing, say so on the call. Visible water in a Flower Mound home changes how quickly a crew is sent. Larger Denton County homes with long runs between fixtures can take longer to test than a compact house.
Keep pets and children away from any warm patch of floor in the Flower Mound house until the cause is known. Lay towels over damp spots and move anything that could be damaged. Avoid pulling up Flower Mound flooring yourself before the leak is found.
Homes in Flower Mound and nearby Grapevine share much of the same ground, so a crew that works here regularly knows what to expect under the slab. Homes in ZIPs 75022 and 75028 are covered from the same 24-hour line as the rest of Denton County.
Ask the Denton County crew to show you the marked location and the test readings. It helps if you want a second view or need to plan around the work. Once the leak is located, the crew explains the repair options for that Flower Mound home and what each involves, before any work is scheduled.
Pipe material in a newer PEX-plumbed Flower Mound home affects which repair makes sense later, so the crew notes it during testing.
Soil around Flower Mound can carry moisture away from a leak or hold it close, so a damp spot is a clue to the leak, not its exact location.
