Slab Leak Detection & Repair in Bargersville, IN

What is a slab leak?

Many homes around Bargersville are built on a concrete slab, with the water supply lines running underneath it. When one of those lines develops a pinhole or crack, the water drains into the soil instead of onto your floor, so the first signs are subtle.

Slab leaks happen on either the hot or the cold side. Hot-side leaks often show up as warm spots on the floor and a water heater that seems to run all the time. Cold-side leaks are usually noticed through the water meter or the bill.

Signs you may need slab leak detection

• Warm or damp spots on tile, wood or carpet
• The sound of running water when every fixture is off
• A water meter that moves with no water in use
• A water bill that jumps for no clear reason
• Cracks in flooring, or baseboards that swell
• A water heater that runs more than usual

Common causes

• Pipes rubbing against concrete, gravel or each other as the house settles and the pipes expand and contract
• Pinholes in older copper lines from age and water chemistry
• Soil movement putting stress on the lines
• Kinks, weak joints or damage during construction

How we locate it

1. Meter and isolation testConfirms there is a leak and whether it is on the hot or cold side.
2. Line pressure testShows which line under the slab is losing pressure.
3. Line tracingMaps where the pipe actually runs under the floor.
4. Acoustic listeningGround microphones pick up the hiss of water escaping under the concrete; the loudest point marks the leak.
5. Thermal imagingA hot-water leak shows up as a warm bloom on the floor surface.
6. Tracer gas (when needed)For quiet leaks in PEX or very small leaks that are hard to hear.

What to do before we arrive

• Do a meter test: turn off all water and watch the meter for one to two hours.
• Close the cold water inlet on the water heater. If the meter stops, the leak is on the hot side.
• If it is a hot-side leak, leave the inlet closed and turn the water heater to vacation or off until the repair.
• Take photos of any warm, damp or damaged flooring for your insurer.

After we find the leak

We mark the leak on the floor and give you photos and readings. Our plumbing partner can then make the repair, so one call covers finding and fixing it. If you already have a plumber, we hand them the marked spot and the report instead.

Common repairs are a spot repair through a small opening in the slab, rerouting the line through walls or the attic, or repiping if the lines are old. Accurate detection keeps a spot repair small.

What affects the cost

The cost depends on how many lines need testing, the flooring and slab above the pipe, and how easy the line is to trace. Detection and repair are quoted separately, and we can arrange both through our plumbing partner. See what affects leak detection cost, or call for a quote for your home.
