Slab leak repair

Small under the slab still gets expensive above it.

A slab leak is a water line beneath your home's concrete foundation that has developed a leak. Without prompt detection, even a small one leads to rising water bills, warped flooring, mold growth, foundation damage and costly repairs. Finding it early is what protects the structure.

Because every slab leak is different, the right repair depends on where the leak is, the condition of the plumbing, and how far the damage has gone. After a thorough inspection and pinpointing the source, we explain the options and give you an honest recommendation before any work begins.

Signs you may have one

It is rarely visible, but it leaves evidence.

A slab leak beneath the foundation is not always visible, but it usually leaves warning signs around the house. If you notice one or more of these, it is worth scheduling detection before the damage gets more extensive.

  • Unusually high water bills
  • The sound of running water when no fixtures are in use
  • Damp or wet floors or carpeting
  • Warm spots on the floor
  • Warped or buckling flooring
  • Musty odors or mold growth
  • Cracks in walls or flooring
  • Foundation movement or settling

Repair options

Three ways to fix it, and they are not equivalent.

Which one is right depends on the location of the leak, the condition of the rest of the plumbing, and the extent of the damage. After detection we explain each option and recommend the one that lasts.

  • Repiping the damaged section, or the whole system
  • Rerouting water lines around the affected area
  • Accessing the plumbing beneath the foundation to repair the damaged pipe

Common questions

Slab leaks, and how they are found.

What is a Slab Leak?

A slab leak occurs when a water line beneath your home's concrete foundation develops a leak. As water escapes, it can seep into the surrounding soil or foundation, leading to higher water bills, moisture problems, foundation movement, and costly damage if left unrepaired. Slab leaks can develop for several reasons, including pipe corrosion, shifting soil, high water pressure, poor installation, normal wear over time, and hard water conditions common in Central Texas.

How Is a Slab Leak Detected?

Professional slab leak detection uses specialized equipment and diagnostic techniques to locate leaks beneath your home's foundation without unnecessary digging. Once the source of the leak is identified, we'll explain your repair options and recommend the best solution for your home.

What Are the Signs of a Slab Leak?

Depending on the area that is leaking, the signs might be hard to spot. Symptoms include increasing water bills without an obvious cause, the sound of running water when no fixtures are in use, warm spots on the floor, damp flooring or carpeting or unexplained moisture, cracks in walls, flooring or the foundation, and foundation movement, uneven floors or sticking doors. If you notice one or more of these warning signs, schedule professional slab leak detection as soon as possible to help prevent additional damage.

Will I See Puddles on the Ground if There is a Slab Leak?

Sometimes. A slab leak may create damp spots inside your home or saturated areas around the outside of your foundation. While visible water can be a warning sign, many slab leaks remain hidden beneath the concrete for quite some time. If you notice unexplained wet areas around your home, it's a good idea to have your plumbing inspected before the damage becomes more extensive.

What Does it Cost to Find and Repair my Leak?

The cost of slab leak detection and repair depends on the location of the leak, the condition of your plumbing system, and the repair method required. Some repairs are relatively straightforward, while others are more extensive. After locating the leak, we'll explain your repair options and provide an honest, no-obligation estimate before any work begins.
