Ground conditions in Schertz
Schertz is a Guadalupe County city northeast of San Antonio with 1980s-2000s subdivisions and more recent growth.
Soil in Schertz is expansive clay. The movement is slow and uneven across a home, which is why a leak is rarely traced to a single event. The effect is a tendency and not a diagnosis. A leak technician locates a leak before saying what caused it. Callers from Schertz reach the same 24-hour line.
Schertz lies along the Interstate 35 corridor northeast of San Antonio, and many of its subdivisions went up within the same few years, so neighbors often share the same pipe material and the same age of line. If one house on a street has had a leak, the others deserve a meter check, because identical lines wear on a similar schedule. A technician can tell you what material runs under your slab before suggesting any repair.
Schertz pipe materials
In Schertz, a home from the 1960s to the 1980s may have copper under the slab, one from the late 1970s to the mid-1990s may have polybutylene, and newer ones have PEX.
Each material has its own failure pattern, which is why the first step is knowing the age of the Schertz home. In newer Schertz homes, a crew starts by checking manifolds and fittings.
In Schertz, if you are unsure of the age or the material, say so when you call. The leak technician verifies before suggesting anything. Newer Guadalupe County subdivisions mostly use PEX under the slab.
What Schertz homeowners notice
Homeowners are inclined to notice a Schertz slab leak because of the bill, a warm spot or a damp patch at a baseboard. Details from your call let the crew arrive in Schertz with suitable equipment.
In Schertz, a water heater that runs more than usual may be replacing hot water that is leaking away. These signs are general. The technician separates the lines and tests them before pointing to a spot.

What is particular to Schertz
In Schertz, many homes are only a few years old, so a builder or plan may still cover plumbing in part. For newer PEX-plumbed homes on expansive clay, this is one of the first things a crew asks about.
Established neighborhoods have big trees close to homes. Roots draw moisture from the soil unevenly, so one side of a slab can dry faster than the other. Roots can also enter and block drain lines. That is a drain-clog topic this site does not cover.
A local crew describes what happens next.
Pinpointing a Schertz leak
Locating a leak starts with the Schertz meter and the valves. Sections are shut off one at a time to find which line is leaking. The aim is to know where to open before any opening is made. See how slab leaks are found. Write down the reading and the time, and mention both when you call from Schertz.

Schertz slab leak questions
Clay swells in wet weather and shrinks in dry spells, slowly stressing lines under the Schertz slab over the years. The cause of a leak only becomes clear once a technician finds it. Crews working in Guadalupe County see this most where a line crosses a footing.
No. A leak in Schertz is a plumbing matter first. This site does not assess foundations, and a foundation contractor handles that question. In newer Schertz houses, cracks and leaks can appear together without one causing the other.
No. In Schertz, isolation, pressure tests, acoustic listening and thermal imaging narrow the search before anything is opened, though the result is not always one exact point. Tell the crew in Schertz the home is on clay that shrinks and swells.
Not always. Sunlight and heating vents can warm a Schertz floor as well. A warm patch that holds in shade, with the heat off, and runs in a line across the floor can point to a hot-water leak. A Guadalupe County crew can tell you how long the visit is likely to take.
Make sure nothing in the house is using water, then watch the meter dial. A turning dial means water is going somewhere on the property. Most newer PEX-plumbed houses in Guadalupe County can be tested without moving furniture far.
In Schertz, 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. Guadalupe County crews start with the simplest test and work toward the slab.
Only the meter check. Leave the Schertz slab intact until testing points to a spot, since guessing can cause damage. Call and a crew will locate it first. Crews covering Schertz can walk you through what this means for a newer house.
In Schertz, flooring contractors handle floors and restoration companies handle drying. This site connects you with leak crews and does not do either. A local crew covering Guadalupe County can walk you through the next step.
Some aging ones do. Houses of that age often have copper under the slab, though a technician confirms what a particular house has.
