Sandy and loamy soils, slab homes
South of San Antonio the soils shift toward sandy and loamy ground, with clay in places. General slab movement is usually less than in North Texas, and homes are overwhelmingly built on slabs, often single-story. Lines run beneath most of the floor area, so the share of a house a leak could be under is large.
Leaks in this region are more often tied to line age, fittings, hard water in some areas, and construction than to broad soil movement. A technician locates the leak and then the cause becomes clear.
Valley and coastal housing
McAllen, Edinburg, Mission, Pharr, Harlingen, Brownsville, Corpus Christi, Victoria and Laredo grew steadily through the 1970s to the present. Older neighborhoods may have copper under the slab, homes of the late 1970s to mid-1990s may have polybutylene, and recent subdivisions mostly use PEX. A technician confirms what a home has.
Say where it is and how long it has been warm.
Telling a warm spot from a warm climate
In a hot climate, tile that is sun-warmed through a window or near an exterior wall can feel warm without any leak. A warm spot from a hot-water line stays warm in shade and at night, follows a line across the floor, and is accompanied by a water heater that runs more than usual. The page on warm spots on the floor goes through the difference.
How the leak is located
A technician isolates hot and cold lines, pressure tests, and listens with acoustic equipment. Thermal imaging may help on tile. These steps narrow the location before anything is opened. They do not always give an exact point.
Tell us what changed.
What happens once the leak is found
In a single-story slab home, the choice between opening the floor at the leak and running a new line above the slab often depends on how much of the house the line crosses. A technician may present spot repair, rerouting, pipe lining or repiping, and explains what steers the recommendation: location, how many leaks the house has had, the line material and what sits over the leak.
No approach is always best. Drying is handled by restoration companies and floors by flooring contractors. The page on slab leak repair and replacement sets the options side by side.
First steps at home
Turn off everything that uses water, including the ice maker and any irrigation, and watch the water meter. If the leak indicator or dial moves, water is escaping somewhere on the property. It does not mean the leak is under the slab. Larger lots and outdoor taps, common across the Valley and the coast, can account for the same reading.
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. Steps are on the water meter leak check page.
