Professional Slab Leak Detection & Repair Services

A slab leak is one of the most serious plumbing issues a homeowner can face. When a water line beneath your home’s concrete foundation begins leaking, it can cause structural damage, mold growth, and rising water bills.


TDI Services provides expert slab leak detection and repair services to quickly locate the source of the leak and restore your plumbing system safely and efficiently. Our licensed plumbing professionals use advanced equipment to minimize disruption while delivering long-lasting repairs.


If you suspect a slab leak, contact TDI Services immediately to prevent further damage.

What Is a Slab Leak?

A slab leak occurs when a water line running beneath your home’s concrete foundation cracks, corrodes, or bursts. Because these pipes are hidden under the slab, leaks often go undetected until noticeable damage appears.


Slab leaks can affect:


  • Hot water lines
  • Cold water lines
  • Main water supply lines


Early detection is critical to preventing foundation damage.

Signs You May Have a Slab Leak

Slab leaks often present subtle warning signs before major damage occurs. Contact TDI Services if you notice:


  • Unexplained increase in water bills
  • Warm spots on flooring
  • Cracks in walls or flooring
  • Damp or wet carpet without visible source
  • Mold or mildew odors
  • Low water pressure
  • Sound of running water when fixtures are off
  • Pooling water near the foundation


Ignoring these signs can lead to costly structural repairs.

What Causes Slab Leaks?

Several factors can contribute to under-slab pipe failure:


  • Pipe Corrosion: Older copper or metal pipes may corrode over time, weakening the pipe walls.
  • High Water Pressure: Excessively high pressure can strain plumbing lines beneath the slab.
  • Shifting Soil: Ground movement can stress pipes and cause cracks or separations.
  • Abrasion: Pipes rubbing against concrete or gravel can wear down over time.
  • Poor Installation: Improper installation during construction may lead to premature pipe failure.

Slab Leak Repair Options

Depending on the severity and location of the leak, we may recommend:


  • Direct Access Repair: Accessing the damaged section beneath the slab to repair or replace the affected pipe.
  • Pipe Rerouting: Redirecting the water line through walls or ceilings to bypass the damaged section.
  • Whole-Home Repiping: If multiple lines are compromised, repiping may provide a long-term solution.
