Slab Leak Detection & Repair in San Antonio
A slab leak is one of the most serious plumbing problems a homeowner can face. Bluebonnet Plumbing uses advanced detection technology to locate leaks precisely and repair them before they destroy your foundation.
What Is a Slab Leak & Why Does It Matter?
A slab leak occurs when a water line running beneath the concrete foundation of your home develops a crack or hole. Because these pipes are buried under several inches of concrete, slab leaks are notoriously difficult to detect — and the longer they go unaddressed, the more damage they cause.
San Antonio's expansive clay soils shift significantly with seasonal moisture changes, putting constant stress on underground pipes. This makes slab leaks more common here than in many other parts of the country. Older homes with copper or galvanized steel pipes are especially vulnerable.
Left untreated, a slab leak can erode your foundation, promote mold growth, cause floors to buckle or crack, and result in thousands of dollars in structural damage. Early detection and professional repair are critical to protecting your home.

Frequently Asked Questions
What are the warning signs of a slab leak?
Common signs include unexplained increases in your water bill, the sound of running water when all fixtures are off, warm or damp spots on your floor, cracks in walls or flooring, low water pressure, and mold or mildew odors. If you notice any of these, call us immediately.
How do you detect a slab leak without breaking concrete?
We use electronic listening devices and pressure testing equipment to pinpoint the leak's location from above the slab. This non-invasive approach allows us to identify the exact spot before any concrete is cut, minimizing damage to your home.
How much does slab leak repair cost?
Slab leak repair costs vary significantly depending on the leak location, repair method, and extent of damage. Spot repairs typically cost less than full re-routing. We provide a detailed written estimate after our detection assessment so you know exactly what to expect.
Will my homeowner's insurance cover a slab leak?
Many homeowner's insurance policies cover the cost of accessing the leak (breaking concrete) and the resulting water damage, but not always the pipe repair itself. We recommend contacting your insurance company and can provide documentation to support your claim.
How long does slab leak repair take?
Detection typically takes 1–2 hours. Repair time depends on the method: spot repairs may take 4–8 hours, while full re-routing can take 1–2 days. We'll give you a clear timeline before starting work.
