Residential Plumbing Slab Leak Detection for Bexar County Homeowners

Most homes in Bexar County sit on concrete slabs with hot and cold potable water lines running beneath or within the concrete. When one of those lines fails, the leak can remain hidden while eroding the ground below your home. American Leak Detection of San Antonio locates the source before any concrete is opened, using Professional Leak Detection Without Destruction™. As the World Leader in Non-Invasive Slab Leak Detection and the original Leak Detection Specialists™, we draw on over 40 years of industry experience to provide a precise, documented target without creating a demolition search zone.

If you’re seeing signs of a slab leak in your Bexar County home, don’t wait for the damage to grow. Call American Leak Detection of San Antonio at (830) 549-2461 to schedule slab leak detection in Bexar County.

Warning Signs of a Slab Leak in Your Home

Slab leaks rarely announce themselves. Most homeowners notice one or two subtle signals before the damage becomes visible. The primary indicator is a water meter that moves when no water is being used, which points to a leak in the potable water plumbing beneath your slab or in the service line running to your home.

Other signs worth taking seriously:

A pump running continuously without an obvious cause
Unexplained spikes in your monthly water bill with no change in usage habits
The sound of running water when every fixture and appliance is off
Warm or hot spots on the floor, often a signal of a hot water line leak beneath the slab
Damp flooring, wet carpet, or warped floorboards with no visible source
Musty odors or mold growth near baseboards or under carpets
New cracks in walls, ceilings, or the foundation that go beyond minor settling

SAWS ConnectH2O provides hourly meter readings through SAWS My Account. SAWS alerts residential customers when it detects continuous water use of at least five gallons per hour for more than 48 consecutive hours. Any of these signs warrants a diagnostic call.

Documented Findings, Upfront Pricing & Repair Choice

Our inspection includes a professional walk-through, non-invasive testing, and clear documentation of the findings. Before leaving your property, we explain the results and identify the marked leak location.

What You Receive After Detection

A precise location gives your repair contractor a defined target. Pinpointing the leak can limit the access area to one spot instead of requiring broad demolition to find the source. The final diagnostic report documents that location so your insurance adjuster or repair contractor has a factual blueprint to work from.

Know Before You Go Pricing
Costs are explained upfront before work begins, with no hidden fees or surprise charges after the job is done.

Optional In-House Repair
If you’d prefer a single point of contact, our repair crew can perform the physical repair using the detection data. This service is optional. You remain free to take the documented findings to any contractor you choose.

Insurer-Preferred Detection
American Leak Detection of San Antonio is preferred by top insurers. Your diagnostic report provides documented findings for insurance-related communication, although coverage depends on the terms of your policy and claim.

Continuous R&D
The franchise system reinvests a significant portion of royalties into research and development, keeping the detection technology and methods used on your property current.

Bexar County Soil & Slab Conditions

Bexar County includes three distinct soil regions that affect how the ground interacts with slab foundations and concealed plumbing. The northern Edwards Plateau has shallow soils over limestone, the mid-county Blackland Prairie contains Houston Black clay, and the far south has sandy soils over clay.

Houston Black clay expands when wet and shrinks when dry, making that movement a primary contributor to foundation concerns in the county. Soil movement also places stress on rigid plumbing lines buried beneath a home.

Slab-on-grade homes can have hot- and cold-water lines beneath or within the concrete foundation. Because these pipes are concealed, a slow leak can continue before visible symptoms appear.

How Slab Leak Detection Works

We locate and mark concealed leaks through tracking the plumbing lines, pressure testing the lines, and determining the location of the water loss and marking the location. Our technicians use professional moisture meters, thermal imaging cameras, and highly sensitive acoustic listening devices to trace the leak. By pressurizing the lines and comparing the diagnostic findings, we isolate the affected area without breaking the surface or using a search and destroy method.

Acoustic sensing identifies the sounds of leaking water in concealed plumbing, while pressure testing confirms whether the plumbing system is losing pressure. Infrared imaging reveals temperature differences associated with concealed hot-water leaks. We use the findings together instead of relying on a single test.

Slab Leak Repair Options to Discuss

Once the leak location is documented, a plumbing contractor can evaluate the pipe condition, access requirements, and extent of the problem. That evaluation determines which repair approach fits the property.

Common repair approaches include:

Spot repair: Accessing and repairing a localized failed section of pipe.
Pipe rerouting: Replacing an affected plumbing run along a new route outside the original damaged area.
Repiping: Replacing a broader portion of the home’s plumbing system when a more extensive solution is needed.

Before authorizing repair work, request a detailed written estimate that identifies the work to be performed and the payment structure. Compare that estimate with the marked leak location and diagnostic report so you understand the proposed access area and scope.

Verifying a Texas Plumbing Company

Texas plumbers are licensed by the Texas State Board of Plumbing Examiners, not the Texas Department of Licensing and Regulation. Before approving slab leak repair work, you can verify the company’s licensing information through the board’s public records.

Check the following before work begins:

Responsible Master Plumber: Use the public license search to confirm the company’s Responsible Master Plumber.
Certificate of Insurance: Review whether the Master Plumber has a current Certificate of Insurance on file.
Complaint history: Contact the Enforcement Department to ask whether valid complaints have been filed against the plumber’s license.
Written scope: Confirm that the estimate clearly describes the proposed repair and payment terms.
