Lake Dallas and the soil under it
Lake Dallas is a small Denton County city beside Lewisville Lake, with homes largely from the 1970s through the 1990s under mature trees.
Slabs in Lake Dallas are built on clay that changes volume with moisture, so every home moves slightly through the year. Lines under the slab feel that movement as repeated modest stresses at bends, tees and footing crossings. Over many years the strain can wear a pipe.

Supply lines in Lake Dallas houses
The usual Lake Dallas home of this age sits on a slab with copper water lines poured into or laid beneath it, though a technician verifies what any one home has.
Copper does not wear evenly. It fails at a few stressed points, and the rest of the line may look fine for years.
If a Lake Dallas home has had one slab leak, ask the leak technician about the condition of the rest of the line before agreeing on a repair.
First clues of a slab leak
Homeowners are inclined to notice a Lake Dallas slab leak because of the bill, a warm spot or a damp patch at a baseboard. A local crew covering Denton County can walk you through the next step.
In Lake Dallas, a warm spot that stays warm in shade and with the heating off, and that follows a line, can suggest a hot-water leak. Sunlight and floor vents warm floors too. See warm spots on the floor and a high water bill from a hidden leak for more on each sign.

What sets Lake Dallas apart
A weekend home can leak unseen. A bill with usage in a month the Lake Dallas home was empty is a strong sign. If you close a home for the season, shut off the main and note the meter. A meter that moves with the main closed points to the yard side.
Established neighborhoods have big trees close to homes. Roots draw moisture from the soil unevenly, so one side of a Lake Dallas slab can dry faster than the other.
A local crew explains what happens next.
Finding the leak in a Lake Dallas home
Locating a leak starts with the Lake Dallas meter and the valves. The technician shuts off sections to pin down which line is leaking. Acoustic equipment then listens along the floor for escaping water, and thermal imaging can show a warm path under tile or wood. Phones are answered around the clock for Denton County calls.

If water is coming up through the Lake Dallas floor, close the main if it is safe to reach, move valuables and call. If anyone smells gas, leave and call the gas utility from outside.
