A slow leak behind a wall or under a slab is one of the most deceptive problems we deal with in Austin. Many of the older homes in Clarksville, Hyde Park, and Travis Heights still have galvanized or early copper supply lines that pinhole-leak from the inside out, so by the time a stain shows up on drywall or a baseboard swells, moisture has often been migrating for weeks. We routinely find hidden rot in wall cavities near kitchens and bathrooms in these neighborhoods, and it's rarely confined to the spot where the stain appears — capillary action pulls water sideways along studs and sill plates.
In newer builds around Mueller and Westlake, PEX and PVC fittings are the more common failure point, especially at manifold connections and under-slab transitions where a fitting wasn't properly seated or was nicked during rough-in. Slab leaks are their own category — Central Texas expansive clay soil shifts with our wet-dry cycles, stressing pipe joints under the foundation. If your water bill jumps or you hear running water with everything off, that's a strong signal, and we bring moisture meters and thermal imaging before anyone opens a wall or breaks concrete.
Code matters here too. Travis County and City of Austin plumbing repairs of this scope generally require permitting and a licensed plumber for the actual pipe replacement — we coordinate with plumbers on the repair itself while our team handles extraction, drying, and reconstruction. Mixing those trades incorrectly is a common mistake that leads to redone work; we've seen drywall closed up over pipe repairs that were never pressure-tested. We also flag when a leak has been active long enough to risk mold — anything past 24-48 hours of standing moisture in humid Austin summers changes the scope from simple drying to containment and remediation.

How it works
- 1
Locate And Confirm The Source
We use moisture meters and thermal cameras to trace the leak path and confirm whether it's active or a past event, since Austin's humidity can mimic ongoing moisture.
- 2
Stop Further Damage
Water is extracted, affected materials are assessed, and if the pipe itself is still leaking we coordinate with a plumber to get it shut off or repaired first.
- 3
Remove Compromised Materials
Wet drywall, insulation, flooring, or subfloor that can't dry in place is removed to prevent mold and speed the drying timeline.
- 4
Dry And Verify
Industrial dehumidifiers and air movers run until moisture readings in studs, subfloor, and slab return to normal, not just until things look dry.
- 5
Rebuild
We restore drywall, flooring, trim, and paint to match, so the repaired area blends back into the rest of the room.
Pricing
Most leaking pipe jobs in Austin run a few hundred to a few thousand dollars depending on how long the leak went undetected and whether walls or subfloor need rebuilding — we give a written scope before starting.
