Seguin and the soil under it
Seguin is the Guadalupe County seat with an aging center, a university area and more recent subdivisions.
Soil in Seguin is expansive clay. The movement is slow and uneven across a home, which is why a leak is rarely traced to a single event. Lines under the slab feel that movement as repeated small strains at bends, tees and footing crossings. Over plenty of years the strain can wear a pipe.

Supply lines in Seguin houses
Seguin has homes from several decades, so what is under a given floor depends on when it was built.
In Seguin, copper wears where it rubs a hard edge as the soil moves. Polybutylene tends to fail at fittings. PEX typically leaks at a single point. A Guadalupe County crew can tell you how long the visit is likely to take.
In Seguin, if you are unsure of the age or the material, say so when you call. The leak technician verifies before suggesting anything. The 24-hour line takes calls from Seguin as well.
First clues of a slab leak
In Seguin, a slab leak hides under concrete, so the first clue is generally indirect. It often starts with a high bill, a warm patch of tile or a faint sound. With shifting clay soil underfoot, Seguin crews look along the entire line.
In Seguin, a hiss or trickle that stops only when the main is closed may point to a leak. Note which room it is loudest in. A technician confirms the cause, and no floor is opened until the leak is located. Mention any earlier leak in the Seguin home when you call.
Say where it is and how long it has been warm.
What sets Seguin apart
Older neighborhoods here include raised homes, with additions on concrete that may have slab leaks. If the Seguin home is in a historic district, ask the local preservation office what applies before a repair is planned.

Finding the leak in a Seguin home
Locating a leak starts with the meter and the valves. By closing off sections, the technician narrows down the leaking line. These steps narrow the location to a modest area. They do not always give an exact point, and the leak technician says how sure the result is. See how slab leaks are found.

Simple checks to start with
Close all water use in the Seguin home and monitor the meter. Movement means a leak, though it may not be under the slab. The crew covering Seguin will want to know what you have already tried.
In Seguin, if you see standing water, keep people away from outlets and appliances, close the main if you can do so safely, and call. See water meter leak check. Guadalupe County crews start with the simplest test and work toward the slab.

Common questions from Seguin
Not always. Sun through a window or a nearby vent can warm a Seguin floor just as easily. Warmth that stays put in shade and with the heat off, and seems to follow a pipe route, can signal a leak on the hot side. Phones are answered around the clock for Guadalupe County calls.
No. Isolating lines, pressure testing, listening and thermal imaging come first in Seguin, and they narrow the location, though not always to a single point. Mention that the home is on clay that shrinks and swells when you call from Seguin.
In Seguin, drain leaks do not follow the water supply, can leave a damp patch or a smell without a bill increase, and are found by isolating and testing the drain system. Ask a crew in Seguin what this means for a varied-age house like yours.
After the repair, a flooring contractor handles the floor and a restoration company handles drying. This site connects you with leak crews and does not do either. Many Guadalupe County homeowners line up flooring work only after the leak is confirmed fixed.
In Seguin, often copper in homes of that age, though a technician confirms what a particular house has.
A leak is one possible reason. Other causes include irrigation and toilets that run, and the meter check separates those from a leak. The usage line on the bill is often where a hidden leak shows first. In Guadalupe County, crews plan the visit around what you describe on the call.
Seguin owners or managers decide. Tell the owner or manager in writing, and whoever has authority can call us. What you share on the call tells a Seguin crew which equipment to bring.
Yes. Because irrigation and outdoor spigots also move the dial, a technician checks them before looking under the Seguin slab. Most mixed-era houses in Guadalupe County can be tested without moving furniture far.
For your Seguin home, a technician may suggest a spot repair, reroute, lining or repipe, and explains the reasoning. A local crew covering Guadalupe County can walk you through the next step.
