Leak Detection in Carrollton, TX
Most leaks in Carrollton are found by their side effects rather than by anyone seeing water. The bill jumps, a patch of floor is warm, a wall smells musty, or the meter keeps ticking with every tap in the house shut. Finding the leak is a separate skill from fixing it, and doing it without opening the house up is the whole point.
Leak detection often leads to a related repair, and our complete plumbing service list covers each of them. When you are ready, contact Pact Plumbing to book a leak detection visit in Carrollton.
The signs Carrollton homeowners call us about
- A water bill that rose without anything in the household changing.
- A warm spot on a tile or wood floor, which on a slab house usually means a hot-water line under the concrete.
- The sound of running water when nothing is running.
- Damp, staining or a musty smell at the base of a wall, in a closet or in the garage.
- Cracks appearing in drywall or a door that has started to bind, where the ground under part of the slab has become saturated.
- Grass that stays green in one strip of a dry yard.
Any one of those is worth a call. Several together usually means the leak has been running for a while.

Why slab-on-grade changes everything here
Carrollton is largely built on slab-on-grade foundations sitting in expansive clay soil. That combination is the reason leak detection matters more in North Texas than it does in a lot of the country.
Clay swells when it takes on water and shrinks when it dries. A supply line leaking under a slab is doing two jobs at once: wasting water, and quietly changing the shape of the ground the house sits on. That is why a plumbing leak in this soil can turn into a foundation conversation, and why finding it early is worth more here than almost anywhere else.
How we actually locate it
The first step is not equipment, it is isolation. We confirm there is a leak at all, then separate the supply side from the drain side, because the two are found in completely different ways and chasing the wrong one wastes the visit.
On the supply side we pressurize and listen. Acoustic equipment picks up the sound a pressurized line makes as it escapes through a break, and that sound carries through concrete. Thermal imaging narrows a warm-water leak on a slab quickly. Tracer gas is the answer where the leak is too small or too quiet to hear.
On the drain side nothing is pressurized, so listening tells you little. There we use a camera in the line and, where the question is whether the under-slab drains hold at all, a hydrostatic test – which is also what a buyer or an agent usually wants to see during a sale.
What you get at the end of the visit
A location, marked. Which line it is, roughly how deep, and what the access looks like. Then the options, because there is nearly always more than one: a spot repair through the slab, a tunnel underneath it so the floor is never opened, or a reroute that abandons the failed run and puts new pipe through the attic or the walls.
Which one is right depends on where the leak is, what the floor finish is, and whether the pipe that failed is likely to fail again a few feet further along. We tell you that rather than picking for you.
The meter test you can run yourself
Before you call anyone, turn off every fixture in the house, including the ice maker and the irrigation, and look at the water meter. If the low-flow indicator is still moving, water is leaving the system somewhere.
If you can find the shut-off at the house and close it, you can go one step further: a meter that stops when the house is isolated points at the yard line between the meter and the house; a meter that keeps moving points inside. Neither answer finds the leak, but both halve the search – and it is a useful thing to be able to tell us on the phone.
Leaks that are not under the slab
Not every hidden leak in Carrollton is a slab leak, and assuming it is can send a job in an expensive direction for no reason. The yard line between the meter and the house fails often, and it announces itself as a soft or unusually green strip in the lawn with no damp inside at all. Irrigation is the other frequent culprit: a cracked lateral or a valve that no longer seats keeps the meter moving and looks exactly like a house leak on the bill.

Inside the house, a supply line running through a wall or an attic can drip for a long time before anything shows, and the stain usually appears well away from the break because water follows framing before it follows gravity. Hose bibs, shower valves, toilet flappers and the connections behind a refrigerator all make bills rise without leaving a mark anybody would notice.
This is why the isolation step comes before the equipment. Ruling out the easy causes takes minutes and occasionally ends the visit there, which is a better outcome for you than a confident diagnosis of something that was never wrong.
If you are buying or selling in Carrollton
Leak detection and hydrostatic testing come up constantly during a sale in North Texas, because a buyer wants to know whether the under-slab drains hold before they own them. If you are on either side of a contract, get the test done early enough that the result can be acted on rather than argued about, and make sure whoever runs it explains what the test does and does not prove.

Carrollton Leak Detection FAQs
How do I know the leak is under the slab and not somewhere else?
A warm spot on the floor, a meter that keeps turning with everything off, or a sound in the floor with the house quiet. Any one of those is worth a call; all three together usually means slab.
Can I test it myself before calling?
Yes. Shut every fixture, read the meter, wait, read it again. If the numbers moved, water is going somewhere it should not.
Does finding it mean breaking the floor?
Not to find it. Locating is done acoustically and with pressure, and the floor only opens where the repair actually has to happen.
What do I get at the end of the visit?
The location, what the line is made of and what the repair options are. On a slab job that usually means repair in place, reroute overhead, or repipe – and which of those makes sense.
We are buying a house in Carrollton. Is this worth doing first?
If the house is slab-on-grade and has any of the signs, yes. It is a lot cheaper to know before the closing than after it.

Carrollton Leak Detection FAQs
How do I know the leak is under the slab and not somewhere else?
A warm spot on the floor, a meter that keeps turning with everything off, or a sound in the floor with the house quiet. Any one of those is worth a call; all three together usually means slab.
Can I test it myself before calling?
Yes, and it’s worth doing before you call anyone. Turn off every fixture and appliance that uses water, note the meter reading, wait 15-20 minutes without touching anything, then check it again – any movement at all confirms a leak somewhere in the system.
Does finding it mean breaking the floor?
No – finding it is non-destructive. We use listening equipment and pressure testing to narrow the leak to a small area before any concrete comes up, so the only opening is the one directly over the actual repair point, not an exploratory trench.
What do I get at the end of the visit?
A clear picture of what you’re dealing with: exactly where the line runs, the pipe material, and a walk-through of your realistic options with the trade-offs on each – direct repair, rerouting the line overhead through the attic, or a fuller repipe – so you’re choosing with the same information we have.
We are buying a house in Carrollton. Is this worth doing first?
Strongly recommend it if the house is slab-on-grade, especially with older cast iron or copper under the slab. A pre-closing leak detection is a small cost next to what a hidden slab leak turns into once you own the house and it’s your problem to fix.
