Slab leak detection is the process of investigating whether a plumbing leak is present and narrowing down its location.
No single visible symptom proves a slab leak; the diagnostic plan should fit the property and the suspected pipe.

When detection testing may help
Symptoms to write down
Write down water-bill changes, meter movement, unusual sounds, warm floor areas, or moisture and when each occurs.
Tell the professional about recent plumbing work and whether the symptoms are constant or intermittent.
What a detection visit can include
The provider should explain the suspected source, which tests may be appropriate, and what the results can and cannot confirm.
Ask whether the diagnostic fee includes locating the leak or only an initial assessment.
Detection methods to discuss
Depending on conditions, a provider may consider pressure testing, acoustic listening, thermal imaging, or other suitable methods.
Equipment is not a guarantee of a diagnosis; interpretation and follow-up testing may be necessary.
What affects testing costs
Ask whether the estimate covers travel, testing, leak location, written findings, and any follow-up visit.
Repair and flooring restoration may be priced separately from detection; get those details in writing.
Finding help in San Antonio
Confirm that the provider serves your address and has experience with the kind of plumbing system involved.
Do not rely on a neighborhood label alone; availability and appointment timing can change.
Questions about test results
Request a plain-language explanation of the test results, the likely leak location, and any remaining uncertainty.
Ask for documentation that can help you compare repair proposals.
More leak detection guidance
Once a leak is confirmed, compare localized repair, rerouting, and other recommendations against the evidence.
Related guides explain repair paths, but the right method depends on the actual pipe and site conditions.
