Why slab leaks happen in Waco
Waco sits on expansive clay along the Brazos River, with firmer ground to the west. The clay swells after rain and shrinks in summer, and slabs move with it.
Neighborhoods near Baylor University and downtown have many older homes with original cast-iron drains and aging supply lines, while newer subdivisions on the edges of town tend to leak at fittings instead.

Do Waco homes near the Brazos River have more groundwater under the slab?
Low-lying areas near the river can hold more moisture, which may leave floors damp without a leak. A meter test tells you whether your plumbing is the source.
Does your Waco home need slab leak detection?
- 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
Our older Waco home has a faint sewer smell in one bathroom. Could it be a broken drain under the slab?
Yes. Cracked cast-iron drains are common in older Waco homes and can let sewer gas into the house. A hydrostatic test and camera inspection show whether a drain under the slab is leaking.
How we find a slab leak in Waco 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.
Your Waco slab leak detection visit, start to finish
A slab leak detection visit in Waco is diagnostic work, not demolition. The plumber who serves your part of McLennan County brings pressure gauges, listening equipment, a thermal camera and line-tracing tools.
The first hour is spent proving there is a leak and narrowing it to one line. Every fixture is turned off, the meter is watched, and the hot and cold sides are separated at the water heater. Only then does the search move to the floor.
Then comes pinpointing: the pipe is traced, the slab is checked for post-tension cables, and acoustic and thermal readings are compared until they agree. That is what makes the mark on your Waco floor reliable.
Before the plumber leaves, you get a written report with the leaking line, the exact location, the readings and photos. Keep it for your insurer, your water utility’s leak credit and whichever licensed plumber you choose for the repair.
Whether you searched for a slab leak plumber or for leak detection slab Waco, TX, the visit follows the same proven steps, and you only pay to find the leak.
We arrange slab leak detection for homes all over Waco, from neighborhoods near Baylor University to those around Cameron Park. Most visits take two to four hours.
Slab leak detection specialist vs. general plumbing contractor in Waco
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 Waco 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 is under the slab in Waco homes
Across Waco: Military rentals near Fort Cavazos, college rentals and older in-town homes. 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.

Our older Waco home was flipped recently. Could the plumbing under the slab be original?
Very possibly. Flips often update fixtures and floors but leave original drains and supply lines under the slab. A drain test and pressure test show their condition.
Before you book slab leak detection in Waco
Five minutes of setup and a two-hour wait will tell you whether your Waco home is losing water.
- 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.

Questions about slab leaks in Waco?
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) 841-0340Do homes near Baylor have more slab leaks because they're rentals?
Rentals aren't the cause, but leaks there often go unreported for weeks because tenants may not see the bill. Owners should check usage regularly.
We're renovating an older house in Waco. Should we test the plumbing first?
Yes. Testing drains and supply lines before new floors go down is much cheaper than finding a leak under brand-new tile later.
Our Waco home near Cameron Park sits on a slope. Does that affect where leaks show?
It can. Water under the slab runs downhill and may surface on the low side of the house, away from the actual leak. Detection follows the pipe, not the wet spot.
Are newer Waco subdivisions safe from slab leaks?
They leak less from worn pipe, but fittings fail and clay still moves. Watch for the usual signs: warm floors, rising bills and running-water sounds.
What does a camera inspection show in an old Waco drain?
It shows cracks, corrosion, root intrusion and separated joints, and pinpoints how far each problem is from the cleanout, so repairs target the right spot.
Can I test my Waco home's drains myself?
You can watch for signs, but a hydrostatic test needs the main drain sealed with a test ball and the system filled to slab level. That's a job for a licensed plumber.

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.
