Greater San Antonio Slab Leak Detection Services

The most important step in solving a slab leak is finding it accurately. Guessing and breaking random sections of concrete is disruptive and expensive. In Greater San Antonio, Christianson focuses on pinpoint leak detection so repairs can be as targeted as possible.

Common warning signs that may point to a slab or foundation leak:

  • Warm or damp spots on tile, wood, or concrete floors
  • Unexplained increases in your water bill with no visible leaks
  • Sounds of running water when fixtures and appliances are off
  • Cracks in walls, tile, or foundation that appear or worsen over time
  • Moldy odors or persistent moisture near baseboards

If you notice one or more of these, there is a strong chance that a pressurized water line under or within your slab is leaking and needs attention.

How we perform slab leak detection in San Antonio, TX:

  • Pressure testing: Verifying which water lines are losing pressure
  • Isolation: Separating hot and cold lines to narrow down the suspect area
  • Acoustic listening: Using sensitive equipment to “hear” leaks through concrete
  • Thermal imaging when helpful: Spotting temperature differences created by hot-water leaks
  • Line tracing: Mapping the path of plumbing under the slab or through walls

By combining these techniques, we can locate leaks with minimal exploratory demolition, keeping your repair costs and disruption as low as possible.
