Leak Detection
A leak in an empty house between tenants can run for weeks, which is why an unexplained bill is worth chasing early.

Schertz grew outward from the old town along FM 3009 and I-35, and it did so in waves — a 1970s core, heavy 1980s and 1990s building, and newer subdivisions since. Almost all of it is slab-on-grade over expansive clay, which is the single most useful thing to know about plumbing here. That clay takes up water and swells after rain, then shrinks hard through a dry summer, and the slab moves with it. Supply lines and sewer lines cast into or running beneath that concrete get worked at the joints season after season.
The other local factor is how many houses are rented or between owners because of Randolph Air Force Base. A leak in an unoccupied house has nobody to hear it, so the first sign is often a bill or a neighbor noticing a wet patch. If you manage a property here, knowing where the meter box and shutoff are is worth more than it sounds.
Occupied or empty
Tell us if nobody is living at the address. Access arrangements and how long the water has been running both change the plan.
Which county you are in
Schertz spans Guadalupe, Comal and Bexar county lines, and the water provider is not the same everywhere. The full address settles it.
Slab and flooring notes
If a slab leak is suspected, say what is on the floor above it. Tile, wood and a kitchen island all affect whether opening or rerouting is sensible.
Repair Decisions
With slab leaks the real decision is the repair route, not whether to repair. One leak in a system that has been trouble-free usually justifies a spot repair through the slab. A second leak in the same house is a signal that the line itself is at the end of its life, and rerouting that run overhead often turns out to be the last repair you pay for on it.
The February 2021 freeze is still worth remembering here: the pipes that split were largely exposed ones in attics, garages and outside walls, and insulating those is cheap compared with the repair. Read about slab leak warning signs and compare options in the water heater repair versus replacement guide if your heater is also on the list.

Schertz Plumbing Questions
How much does emergency plumbing cost in Schertz?
You are quoted before anything starts. The cost drivers are the type of repair, the access needed and whether parts have to be sourced — a slab leak reroute and a fixture repair are not comparable jobs. San Antonio 24 Hour Plumber prices at the property after the cause is confirmed. See how a service call works.
Who can find a slab leak near me in Schertz?
San Antonio 24 Hour Plumber locates slab leaks in Schertz using pressure testing and acoustic equipment before any concrete is opened. If you have a warm spot on the floor, running water you cannot see or a jump in usage, that is the place to start — details are on our slab leak repair page.
Can I get a same-day plumber in Schertz?
Generally yes. San Antonio 24 Hour Plumber confirms a time window once you give the address, and active leaks and sewer backups take priority over scheduled work. If the repair needs a specific part, that may push part of the job to a second visit, and you will be told when you approve the quote. Describe the problem to get a window.
Is it safe to leave the water on if I think there is a slab leak?
Not for long. A slab leak is washing soil out from under the foundation the entire time it runs, and on clay soil that uneven wetting is exactly what causes movement. If the leak is on the hot side, switching the water heater off reduces the loss while you wait. If flooring is lifting or baseboards are wet, shut the main at the meter box and call San Antonio 24 Hour Plumber.
Should I repair the slab leak or repipe the house?
It depends on the history. A first leak is normally a spot repair or a reroute of that one line. Once a house has had two or three, the pipe is telling you it has reached the end, and repiping stops the cycle. San Antonio 24 Hour Plumber will show you what was found and quote the realistic options side by side rather than defaulting to the largest one — see leak detection for the first step.
What should I do about a leak in a house nobody is living in?
Shut the water off at the meter box as soon as you can get someone there, then arrange the visit. In rental and between-owners properties around the base, leaks often run for weeks before anyone notices, so the damage is usually worse than the plumbing fault itself. San Antonio 24 Hour Plumber can meet an agent or a neighbor with access — note that on the service request.
