Slab Leak Detection in Cedar Park, TX
Slab leak detection in Cedar Park finds a leaking water or drain line under your concrete foundation without tearing up your floors. A licensed local plumber confirms the leak, isolates the line, then pinpoints it with acoustic, thermal and pressure tools so only a small, precise opening is needed.
- Acoustic listening
- Thermal imaging
- Tracer gas
- Pressure & hydrostatic tests
- Camera inspection
Why slab leaks happen in Cedar Park
Central Texas soil changes at I-35: east of it is Houston Black Clay that swells and shrinks dramatically, while the west side is thin soil over limestone. Drought cycles and water restrictions make the movement worse.
Cedar Park sits on thin soil over limestone, and its 1980s–2000s homes are reaching the age when copper lines fail.

Why does it matter which side of I-35 my Cedar Park home is on?
East of I-35, homes sit on Houston Black Clay that moves a lot, so pipe stress is the main risk. West of it, homes sit on limestone, where movement is smaller but reaching a leak through the slab takes more work.
Signs of a slab leak in your Cedar Park home
- 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
My carpet is damp near a wall in my Cedar Park home. Is it a slab leak?
It can be. Water from a leaking line under the slab often wicks up at the edges of a room or near a plumbing wall. Rule out a leaking toilet, tub or water heater nearby first, then test the lines under the floor.
How we find a slab leak without tearing up your floor
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.
Slab leak specialist vs. general plumbing contractor
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 Cedar Park 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.

What our slab leak detection covers in Cedar Park
We do one thing: find leaks under concrete slabs. Every visit is done by an independent, licensed Texas plumber who specializes in leak detection, so you pay to find the leak, not to break concrete searching for it.
Water Line Leaks
Find leaks in the pressurized supply lines buried in or under your slab.
Hot-Water Line Leaks
Thermal imaging traces warm spots and leaking hot-water runs.
Drain Line Leaks
Hydrostatic and isolation tests find drain leaks that never show on your meter.
Pressure Testing
Confirm a leak exists and measure how fast the line loses pressure.
Line Isolation & Tracing
Separate hot, cold and branch lines and map where they really run.
Acoustic Pinpointing
Ground microphones hear escaping water through the concrete.
Tracer Gas Detection
For very quiet leaks and plastic pipe, gas rises at the leak point.
Written Leak Report
Exact location, readings and photos for your insurer or water utility.

Will I still pay for detection if no leak is found?
Usually yes, because detection is a diagnostic service. If no slab leak is found, you still learn where the water isn't going, which rules out costly guesses. Ask about the fee before the visit.
Find the leak first. Don’t pay anyone to search.
Most of the cost of a slab leak comes from searching for it and repairing the floor afterward. Slab leak detection is all we do, so you get an exact location before anyone touches your floor.

Questions about slab leaks in Cedar Park?
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 (000) 000-0000Does Cedar Park give a water credit for a slab leak?
Yes. Cedar Park’s water credit lists leaks in the slab, and you can request it once a year within 6 months of the repair. It’s half the difference between your highest bill during the leak and your normal usage, so keep the plumber’s invoice.
Do drought and water restrictions cause slab leaks in Cedar Park?
They contribute. When clay dries out during drought, it shrinks and pulls away from the slab, and then swells again after rain. That movement stresses pipes, so leaks often show up when a dry spell ends.
Is slab leak detection harder in Cedar Park because of rock?
Detection itself works the same way: pressure tests, acoustic listening and thermal imaging all read through the slab. Rocky ground west of I-35 makes reaching a pipe slower, which is exactly why pinpointing the exact spot first matters so much.
Is a slab leak in my Cedar Park home an emergency?
Water coming up through the floor, a sewer smell or a fast-spinning meter needs help the same day. A slower leak should still be checked within days, because water under the slab can wash out soil and grow mold.
Why is there a warm spot on my floor?
A warm spot on tile, wood or carpet is a classic sign of a leaking hot-water line under the slab. Thermal imaging can confirm it and trace the line. Turn off the water heater's cold inlet and call a plumber.
How long does slab leak detection take in Cedar Park?
Most leaks are located in two to four hours. Complex homes, multiple leaks or drain problems can take longer. You'll get the results, the exact location and a written report before anything is opened.
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
The City of Cedar Park’s water credit covers underground leaks, leaks behind walls and leaks in the slab. You can request it once a year, within 6 months of the repair date, and the credit is half the difference between your highest bill during the leak and your normal usage. Source: City of Cedar Park.
Keep your invoice, and call your utility soon after the repair to ask about its rules and deadline.
