Signs You May Have a Slab Leak

Slab leaks can be tricky to detect, but here are some common warning signs:

  • Unexplained Spikes in Your Water Bill: A sudden increase could indicate hidden water loss.
  • Hot or Cold Spots on Your Floor: This is a strong indicator of a leak under the slab.
  • Pooling Water: Water appearing where it shouldn’t is a clear red flag.
  • Decreased Water Pressure: A loss of pressure may suggest pipe damage.
  • Mold or Mildew Odors: Lingering smells often accompany undetected leaks.
  • Soggy Carpets or Flooring: Dampness in unexpected areas can signal trouble beneath your foundation.

If you notice any of these symptoms, call us immediately to prevent further damage and costly repairs.
