Professional Slab Leak Repair in Austin, Texas
A slab leak is a water line or drain line failure beneath your home's concrete foundation. In Austin, slab leaks are among the most common plumbing emergencies for homes built between 1960 and 1995 — particularly in neighborhoods like Allandale, Crestview, Barton Hills, South Lamar, Windsor Park, and North Loop where aging copper supply lines are embedded in the original slab.
Left unrepaired, a slab leak erodes the soil beneath your foundation, causing differential settling that cracks floors, walls, and door frames. Water migrating upward through the concrete creates ideal conditions for mold growth under flooring. Your water bill climbs steadily as hundreds of gallons per day escape underground. The longer a slab leak runs, the more expensive the structural consequences.
We use thermal imaging cameras and electronic acoustic listening equipment to precisely locate the failure point before any repair work begins. This means we only access the foundation at the exact leak location — not a wide search trench — minimizing concrete cutting and restoration cost. In many cases, we recommend pipe rerouting: running new copper or PEX supply lines through the walls and attic above the slab, bypassing the leaking underground pipe entirely.
Signs You Have a Slab Leak
Our Slab Leak Repair Methods
Thermal Imaging Detection
Infrared cameras detect temperature differences caused by water leaking from hot or cold lines beneath the slab. Pinpoints the leak location to within inches without any excavation.
Electronic Acoustic Detection
Sensitive listening equipment amplifies the sound of water escaping under pressure through a pinhole. Effective for locating cold water line leaks where thermal imaging has limits.
Pipe Rerouting (Above Slab)
New copper or PEX lines run through interior walls and attic space, bypassing the leaking underground pipe. No concrete breaking required. Most cost-effective option for accessible pipe runs.
Spot Access Repair
When rerouting is not feasible, we cut a precise access opening in the concrete at the leak location, make the repair, and restore the concrete. Minimizes impact compared to exploratory trenching.
Epoxy Pipe Lining
Structural epoxy applied from inside the pipe seals pinholes and corrosion without excavation. Best for isolated pinhole leaks in pipes that are otherwise in good condition.

Slab Leak FAQs — Austin TX
What are the signs of a slab leak in an Austin TX home?
Common signs: sudden water bill increase, warm spots on the floor (hot water line), sound of running water with everything off, cracks in walls or flooring, damp carpet near walls, mold smells at floor level. Call for inspection if you notice any of these.
How much does slab leak repair cost in Austin TX?
Detection costs $150-$300. Pipe rerouting (above-slab bypass) runs $2,500-$5,000 and avoids breaking concrete. Spot access repair where concrete is cut at the precise leak point runs $800-$2,500. Full re-piping ranges higher depending on home size.
Why are slab leaks so common in Austin?
Austin's clay and limestone soil shifts with seasonal moisture — expanding in wet weather, contracting in dry. This ground movement flexes the slab and fatigues the copper pipes within. Hard water accelerates pipe corrosion from inside. Homes built in the 1970s-1990s in north and central Austin neighborhoods are at highest risk.
Does homeowners insurance cover slab leaks in Texas?
Most Texas homeowners insurance covers sudden and accidental slab leaks and the resulting water damage, but excludes gradual leaks due to lack of maintenance. Coverage specifics vary by policy. We provide detailed documentation of the leak cause, location, and repair method that your adjuster will need.
