Your Solution for Urgent Repairs

Strategic Slab Leak Detection

A warm spot on your floor. Water bills that jump without explanation. The faint sound of running water when everything’s turned off. These are warning signs of a slab leak, which is one of the most serious plumbing issues a homeowner can face in the Lowcountry.

Plumb Pro+ has been locating and repairing slab leaks for families and businesses for more than 20 years. We use acoustic listening equipment and thermal imaging to pinpoint the exact location beneath your foundation before cutting begins.

What Is a Slab Leak?

A slab leak happens when the pipes under your home’s foundation crack or break. These leaks aren’t visible — they’re buried beneath concrete, where water escapes under pressure, saturates the soil, weakens your foundation, and can lead to mold growth and structural damage. Most Charleston-area homes built on slab foundations have copper or PEX water lines beneath the concrete. Over time, shifting soil, corrosion, or high water pressure can cause these lines to fail.

Signs You May Have a Slab Leak

Because these leaks are buried, watch for these clues:

  • Unexplained spikes in your water bill: Water could be escaping underground while usage remains normal.
  • Warm or damp spots on the floor: These spots could indicate that hot water is leaking beneath the slab, heating the concrete above.
  • The sound of running water: This sign could indicate flowing water beneath the foundation when all fixtures are off.
  • Cracks in walls or flooring: The foundation shifts as water erodes soil beneath your slab.
  • Low water pressure: A leak diverts water before it reaches your faucets.

How We Detect Slab Leaks

We rely on precision technology for slab leak detection before any concrete is touched:

  • Acoustic listening equipment amplifies the sound of pressurized water escaping, narrowing the leak location to within inches.
  • Thermal imaging cameras detect temperature changes caused by hot or cold water leaking beneath the slab.
  • Pressure testing confirms which line is leaking by isolating sections and testing for pressure loss.

Repair Options After Detection

Once we locate the leak, we discuss repair approaches such as targeted spot repair, cutting only the affected section, line rerouting that bypasses the slab by running new lines through walls or the attic, or pipe lining, which seals cracks with epoxy. The right choice depends on your plumbing’s age, the location of the leak, and your plans for the home.
