- Acoustic listening
- Thermal imaging
- Tracer gas
- Pressure & hydrostatic tests
- Camera inspection
Southlake slab leak detection starts with these signs
- Water bill jumped with no change in use
- Meter keeps moving with everything off
- Warm spot on tile, wood or carpet
- Running-water sound when nothing is on
- Water heater runs constantly
- Damp carpet, cupped wood, musty smell
- Sewer smell or slow drains
- New cracks or sticking doors
There's a faint warm line across our Southlake marble floor. Could it be a hot-water pipe leaking?
It could. A hot line leaking under the slab warms the stone above it, sometimes in a strip that follows the pipe. Thermal imaging can confirm it and trace the line without touching the marble.
Before you book slab leak detection in Southlake
This simple test tells you whether water is escaping somewhere in your Southlake home before you pay for a visit.
- Turn everything off. Faucets, dishwasher, washer, ice maker, sprinklers and pool fill.
- Find your meter. It is usually in a box near the street. Read the number or take a photo.
- Wait one to two hours. Use no water at all during that time.
- Read it again. If the number moved, or the small leak indicator is spinning, water is escaping.
- Narrow it down. Close the house shut-off. If the meter keeps moving, the leak is in the yard line; if it stops, it is inside, possibly under the slab.

Why slab leaks happen in Southlake
Southlake homes are large, and large homes have long supply runs under the slab. Hot-water lines expand and contract every day, and over long runs that movement gives a pinhole more places to start. The clay underneath shifts with wet and dry seasons as well.
Many homes here also have high-end flooring across the ground floor. Opening it in the wrong place is expensive, so an exact location, or a reroute that avoids the floor, saves money twice.
Serving homes across Southlake, including neighborhoods near Southlake Town Square, Bob Jones Park, Southlake Boulevard.
Do large Southlake homes have more places for a slab leak to start?
Yes. Longer runs, more bathrooms and recirculation loops all mean more pipe under the slab. Isolating each line first keeps the search to one pipe instead of the whole house.
What is under the slab in Southlake homes
Across Southlake: 1960s–80s brick ranches with cast-iron drains, plus larger 1980s–2000s homes with copper supply lines. Knowing what pipe is under your floor tells the plumber which slab leak detection method will work best.
Copper supply lines
Common in homes built from the 1960s through the early 2000s. Copper wears where it rubs against concrete or gravel, and pinhole leaks show up as homes pass 25–40 years old. Acoustic listening finds them well.
Cast-iron drains
Standard in homes built before about 1980. Cast iron rusts from the inside and cracks as the slab moves. Drain leaks never show on the water meter, so a hydrostatic test and camera inspection are used.
Polybutylene
Gray plastic pipe installed from about 1978 to 1995. It is known for failing at fittings. Tracer gas and pressure testing are often the best ways to locate leaks in it.
PEX and newer plastic
Used in most homes built since the 2000s, often run from a manifold. PEX leaks are usually at fittings or where the pipe was nicked during construction. Each run can be pressure-tested from the manifold.
Nine steps of slab leak detection in Southlake
The same nine steps on every job, so you know what’s happening and why. Read the full process →
Listen and look first
The plumber hears what you've noticed and walks the home to look for clues.
Rule out the easy causes
Toilets, faucets, irrigation, the water heater and the AC drain are checked so you don't pay to search for the wrong leak.
Confirm the leak with the meter and a pressure test
A meter test and a pressure test prove water is escaping from the plumbing.
Isolate the leaking line
Hot, cold and branch lines are separated so the search focuses on the one that's leaking.
Test the drains, if needed
Drain leaks don't show on the meter, so they get their own hydrostatic test and camera check.
Trace the pipe's route
An electronic locator maps where the leaking line actually runs under the floor.
Pinpoint the exact spot
Acoustic listening, thermal imaging and tracer gas find where the water is escaping, and two methods must agree.
Scan the slab and mark the leak
The slab is checked for steel tendons and rebar, and the leak is marked on the floor.
Get your written report
You receive the leak's location, the line, the readings and photos in writing.

What a slab leak detection visit in Southlake looks like
When you book slab leak detection in Southlake, a licensed plumber who knows Tarrant County homes comes to you with the tools to read through concrete: pressure gauges, acoustic ground microphones, thermal imaging and tracer gas.
Before any listening starts, the plumber rules out toilets, faucets, irrigation and the water heater, then pressure-tests the system. Closing the cold inlet at the water heater shows whether the leak is on the hot or cold side.
With the leaking line identified, its route is traced across the floor and the plumber listens through the slab in a grid. On hot-water lines, a thermal camera shows the warm patch spreading from the leak. The exact spot is marked only when two methods agree.
You finish the visit with the leak marked on the floor and a written report in hand. That report is what makes slab leak detection in Southlake worth it: no one has to search by breaking concrete.

Southlake slab leak detection specialist vs. a general plumber
Many general plumbers do excellent work. The difference is focus and equipment when the leak is hidden under concrete.
| What matters | Slab leak detection specialist (our network) | Typical general plumbing contractor |
|---|---|---|
| Main focus | Only finding hidden leaks under slabs | Installs, repairs and remodels across all plumbing |
| Detection tools | Acoustic ground mics, thermal imaging, tracer gas, line tracing | Varies; often a pressure test and visual inspection |
| Locating the leak | Pinpointed before any concrete is opened | May open the floor in more than one place to search |
| Drain leaks under slab | Hydrostatic, isolation test and camera find the broken section | May recommend replacing the whole drain system |
| After the leak is found | Exact spot marked and documented; you choose who fixes it | Often moves straight into its own repair or repipe |
| Paperwork | Written report with photos for insurance and water credits | Usually an invoice only |
| Typical cost to locate | $150–$600 in most Southlake homes | Varies; exploratory openings add cost |
Tip: whoever you call, ask which detection methods they use and whether they’ll pinpoint the leak before opening the slab.

Insurance and slab leaks in Texas
Coverage depends on your policy and the cause. The Texas Department of Insurance has long said the standard HO-B policy covers damage to the dwelling, including the foundation, from an accidental discharge of water from a plumbing system. Many policies still exclude wear and tear, the pipe itself, and mold.
What helps your claim: shut off the water, protect your belongings, and get the leak documented by a licensed plumber before the adjuster visits.
Ask for a leak credit
Many Texas cities and MUDs credit part of the water lost to a hidden leak once it’s repaired. Most want a paid plumber’s invoice and a request within a set number of days, and allow one credit a year.
Keep your invoice, and call your utility soon after the repair to ask about its rules and deadline.
Questions about slab leaks in Southlake?
Still not sure if you have a slab leak? Call and describe what you’re seeing. A licensed plumber will tell you whether it’s worth a visit.
Call (833) 841-0340Our Timarron home has a hot-water recirculation pump. Does that affect leak detection?
It adds a loop of hot pipe that may run under the slab and keeps water moving constantly. The pump is switched off and the loop isolated during testing, so its line can be checked on its own.
Will our Southlake insurance cover lifting and relaying stone tile after a slab leak?
Many policies cover tear-out and resulting water damage from a sudden leak, but not the pipe or wear and tear. Matching costly stone is a common dispute, so photos and a written detection report help.
How do you find a leak under a Southlake kitchen island without moving it?
The line is traced and listened to around the island, and thermal imaging checks hot lines. The exact spot is marked, and a reroute can often avoid touching the island at all.
Our Southlake home has a whole-house water filtration system. Can it hide a leak?
It can add its own small leaks or drain cycles. Put it in bypass before the meter test so any movement you see is coming from the house plumbing.
Are newer Southlake custom homes immune to slab leaks?
No. Newer homes leak less from worn pipe, but fittings fail and lines can be damaged during construction. Clay movement affects new slabs too.
How long do Southlake homeowners usually wait for a detection visit?
Most visits can be scheduled within a day or two, and same-day help is the priority when water is coming up through the floor. Detection itself usually takes a few hours.
