What our leak detection service includes
Every leak detection call includes a full system check, not just a quick listen. We test pressure, scan with acoustic and thermal gear, and confirm the leak location.
Work order
Leak Detection and Repair- Full pressure test: We isolate the system and attach a pressure gauge to your hose bib. A drop in pressure tells us the leak is on the supply side. This step takes 15 minutes and confirms the leak is real.
- Acoustic listening scan: We use a listening disc to hear water escaping pipes under slabs or behind walls. The microphone amplifies the sound so we can narrow the leak to a small area. We scan every room and the yard.
- Thermal imaging: A thermal camera shows temperature differences caused by leaking hot water. We use it to confirm slab leaks and find leaks behind tile. It's non-invasive and takes about 20 minutes.
- Leak location marking: Once we find the leak, we mark the spot with tape or paint. You see exactly where the problem is before we cut anything. That keeps the repair focused and your home intact.
- Written findings: You get a written summary of what we found, where it is, and what it takes to fix it. We include photos when helpful. That documentation is useful for insurance claims.

What leak detection schertz TX really involves
A hidden leak wastes water and damages your home. We find it with acoustic and thermal gear, repair it, and test the line. That's how you stop the damage and the high bills.
Leak detection schertz TX is the process of finding water escaping from your plumbing system before it damages your home. We start by isolating the system, then use acoustic listening equipment and thermal imaging to hear and see water where it shouldn't be. From there we pressure-test lines, check your water meter, and confirm the exact location. Once we know where the leak is, we repair it with copper pipe, PEX tubing, or PVC pipe to match your existing system.
In Schertz, most hidden leaks we find come from three places: slab foundations, aging copper under the slab, and irrigation lines that cross under the driveway. The clay soil here shifts with wet and dry cycles, and that movement stresses pipes until they crack. If you've noticed a spike in your water bill or a warm spot on the floor, that's often a slab leak. We also handle underground water leak repair schertz when the leak is outside the foundation.

How leak detection runs in Schertz
Schertz sits on clay soil that expands and contracts with the seasons. That movement cracks copper pipes under slabs, especially in homes built before 1990. We see a spike in slab leaks after a dry summer followed by heavy fall rain.
Schertz Parkway area
Mix of 1980s and 1990s homes with original copper under the slab. We see slab leaks here often after dry spells.
Cibolo Canyons
Newer construction with PEX tubing. Leaks here are usually at fittings or from high water pressure.
Universal City
Older homes with galvanized pipes that corrode. We often replace sections with copper or PEX.

PhotoSlab leak rerouted in Schertz
Before: We found a slab leak under the hallway with acoustic gear. The copper pipe had cracked from soil movement.
After: We rerouted the line through the attic with PEX tubing.
Underground line repaired in Cibolo
Before: A Cibolo homeowner had a soggy spot in the yard and a water bill that doubled. We used acoustic listening to find a leak in the main line, 12 feet from the foundation. The PVC pipe had cracked from root intrusion.

Shower valve leak fixed in Universal City
Before: A Universal City homeowner saw water stains on the ceiling below the bathroom. We found a leaking shower valve behind the tile. The copper pipe had a pinhole leak from high pressure.

Hidden leak detection schertz Texas problems we solve
Hidden leaks don't fix themselves. They get worse, cost more, and damage your home.
Water bill doubled with no visible leak
You're paying for water that's soaking into the ground or under your slab. A leak the size of a pencil tip wastes 8,000 gallons a month.
Warm spot on the floor
A warm spot means hot water is leaking under your slab. The heat softens the soil and can crack your foundation.
Sound of running water when everything is off
That sound is water moving through a broken pipe. It could be a supply line, a drain line, or a toilet flapper.
Soggy spot in the yard
An underground water leak can erode soil and create a sinkhole. It can also undermine your driveway or sidewalk. The leak won't stop on its own.
Why Schertz homeowners call us first

Still have a question?
Describe what you are seeing and we will point you to the right next step.
876383746The three clearest signs are a water bill that jumps 20% or more, the sound of running water when everything is off, and warm spots on a slab floor. Check your water meter before bed and again in the morning. If the dial moved and nobody used water, you have a leak. We can pressure-test your system to confirm.
Slab leaks and underground lines take longer and cost more. The detection fee is separate from the repair. We quote both upfront so you know the total before we start.
Yes. We repair slab leaks by either cutting into the slab at the leak point or rerouting the line through the attic. Rerouting is often faster and avoids breaking your floor. We use copper pipe or PEX tubing for the new line, then pressure-test it. Most slab leak repairs take one to two days.
The biggest cause is soil movement. Schertz sits on clay soil that expands when wet and shrinks when dry. That shifting cracks copper pipes under slabs. Other causes include high water pressure above 80 psi, aging galvanized lines, and tree roots pushing into sewer lines. A pressure regulator can prevent future leaks.
