Turn off every fixture and watch the water meter. If it still moves, a leak is running somewhere. Shut the main if water is showing, then call. A local leak detection technician uses pressure tests, acoustic listening and thermal imaging to pin the leak down without wide demolition, so a plumber can repair the right spot and drying can start.
Is This What You Are Seeing in Your Keller Home?
- Rising water bill. Usage climbs from one month to the next with no new pool, guests or landscaping.
- Meter moves with taps off. The low-flow indicator on the meter spins while nothing in the house is using water.
- Warm floor patch. One area of tile or concrete feels warm underfoot, often near a bathroom or the kitchen.
- Water heater runs constantly. The heater cycles far more than usual.
- Damp baseboard. Baseboard or carpet tack strip along an interior wall stays damp or smells musty.
- Cracks and low pressure. New floor cracks, a sticking door or weak pressure at one fixture can point to a line under stress.
Two or more of these? Water has likely spread further than it looks.

Not every leak announces itself with a puddle. In Keller, the first clue is often a water bill that suddenly runs higher than the same month last year, a warm spot on a tile floor, a hissing sound in a quiet house, or a patch of carpet that never quite dries. By the time water shows on the surface, it has usually been running for a while. Finding the exact source keeps the repair small.
The hard part is that most supply lines are buried. Water lines in many Keller homes run under or through the slab, up inside interior walls and across the attic to the water heater, ice maker and hose bibs. A leak in any of those places can soak insulation, wick up drywall from the bottom plate, or spread under flooring for weeks. Slow drips can also feed mold in closed wall cavities.
A leak detection technician works from the meter inward. The first question is whether the loss is on the main line from the meter, the hot side, the cold side or a single fixture. Pressure tests narrow it further. Acoustic ground microphones pick up the sound of water escaping a pressurized pipe, thermal cameras show warm or cool trails across a floor, and moisture meters confirm what the camera suggests. The goal is a marked spot, not a guess.
Keller sits on the expansive clay soil common across DFW, which shrinks in drought and swells after heavy rain. That cycle moves slab foundations and can stress the copper or plastic lines running beneath them, so slab leaks are one of the most frequent hidden leaks here. Attic plumbing is the other common suspect, since many homes here put the water heater upstairs.
Do These Things Before the Crew Arrives
- 1Do the meter test Turn off every faucet, the ice maker and the irrigation, then watch the meter dial or leak indicator for movement.
- 2Shut the main if water shows If you can see water on a floor or ceiling, close the main shutoff near the street or in the garage.
- 3Feel the floors Walk the house barefoot and note any warm spot on tile or concrete, a common sign of a hot water slab leak.
- 4Listen in a quiet house With everything off, listen near walls, the water heater closet and the floor for hissing or running sounds.
- 5Check the water heater Look at the attic or garage water heater, its pan and its supply connections for drips or rust.
- 6Write down what you notice Note the bill change, when the damp spot appeared and any sounds.
How a Keller Crew Handles Leak Detection Services
- 1
Confirm a leak exists
The technician starts at the meter, shuts down fixtures and the irrigation system, and watches flow for several minutes to prove water is escaping before searching anywhere.
- 2
Isolate the system
Valves are closed in sequence to separate the main service line, the hot side, the cold side and individual branches, which shrinks the search to one section.
- 3
Pressure test lines
A gauge on the isolated section shows whether it holds pressure, confirming which line is leaking and roughly how fast water is being lost from it.
- 4
Listen and scan
Acoustic ground microphones trace the sound of escaping water along the pipe route while a thermal camera shows warm or cool trails across floors, walls and ceilings.
- 5
Mark the spot
The technician confirms the reading with moisture meters, marks the leak location on the floor or wall, and records photos and notes for the repairing plumber.
- 6
Plan the drying
Once the source is found, the wet area around it is measured so a local restoration crew can extract, dry and remove damaged materials after the repair.
Why It Happens in Keller Homes
- Slab movement
- Expansive clay soil under Keller homes shrinks and swells with drought and rain, which can stress and crack pipes running below the slab.
- Attic water heater lines
- Supply and relief lines to an attic water heater can drip into insulation for a long time before a ceiling stain shows.
- Pinholes in copper
- Older copper lines in 1980s and 1990s homes can develop tiny pinholes that spray inside a wall cavity.
- Fitting failures
- Crimp rings, compression nuts and push fittings on newer plastic lines can loosen and weep at a joint hidden behind drywall.
- Irrigation and yard lines
- A cracked sprinkler line or service line in the yard can show up only as a soggy spot and a higher bill.
Keller's homes went up mostly between the 1980s and the 2000s, from the older streets around Old Town Keller to the master-planned sections of Hidden Lakes and Marshall Ridge. Almost all of them sit on slab-on-grade foundations over the shrink and swell clay that runs across the region. Hot summers dry that soil and spring storms soak it again.
For leak detection, that means a technician has to think in three layers: the slab, the walls and the attic. A warm floor in a Keller kitchen or a damp hallway carpet points to the slab. A stain on an upstairs ceiling often traces to the attic water heater. Listening, pressure testing and thermal scans separate those layers before anyone cuts.
What It Costs and How Long It Takes
Typical cost in Keller
A leak detection visit typically runs $150 to $500, depending on how many lines need isolating. If the leak already soaked materials, a thermal imaging or moisture inspection of the wet area runs about $200 to $600, and drying clean water is about $3 to $7.50 per sq ft. The plumbing repair itself is priced separately by the plumber. General market ranges, not quotes.
Timeline
Most leak detection visits are finished in a single appointment, and the marked spot can be repaired soon after. If drying is needed, it usually runs three to five days once the leak is stopped.
Can you handle it yourself?
The meter test, a barefoot walk for warm spots and a look at the water heater pan are safe and useful. Opening walls or concrete to hunt for a leak is not, because guessing wrong adds repair cost, so let a technician pinpoint it first.
How to Keep It From Coming Back
- Read the meter monthly. Check the low-flow indicator once a month with everything off so a slow leak is caught early.
- Watch the water bill. Compare each bill with the same month last year, since seasonal irrigation hides small jumps.
- Water the foundation evenly. Steady soaker hose watering around the slab in dry spells limits soil movement.
- Inspect attic plumbing. Look at the water heater pan, relief line and supply fittings in the attic at least twice a year.
- Install leak alarms. Place small water sensors at the water heater, under sinks and behind the fridge.
Leak Detection Services FAQs
How do I know I have a slab leak?
Common clues are a warm patch on the floor, the sound of running water with all taps off, a meter that keeps moving and a bill that keeps climbing. A pressure test on the isolated lines confirms it.
Does leak detection mean breaking up my floor?
No. Detection itself is done with gauges, microphones and cameras from the surface. Only the repair needs an opening, and a precise mark keeps that opening small.
Can a thermal camera find every leak?
Not alone. Thermal imaging shows temperature differences, but technicians confirm with meters and acoustic tools before marking a spot.
What if the leak is in the attic?
Attic leaks often come from water heater lines or relief valves. The technician traces them with moisture readings in the insulation and ceiling, then a restoration crew dries or replaces the wet materials.
What about a leak out in the yard?
A technician can tell whether the leak is on the yard service line, an irrigation branch or inside the home.
What happens after the leak is found?
A plumber repairs the line, and a local restoration pro dries the slab, walls or ceiling around it. Calling one number connects you with the pros who handle both steps.
