The Dangers of a Slab Leak

Slab leaks are the most damaging type of plumbing leak. Because they occur under the slab foundation of your home or place of business, they can go unnoticed for a long time, causing you to waste several gallons of water and a sudden surge in your water bill. Even with just a pinhole-sized slab leak, continuous water saturation of your foundation can result in wood rot, mold growth, and other structural damage.

Below are some serious issues you could be facing when slab leaks remain unaddressed:

  • Health problems caused by mold growth such as coughing, wheezing, and other respiratory conditions
  • Repair and restoration expenses from the water damage
  • Potential electrocution or fires if the water comes into contact with electricity
