Offering Reliable Slab Leak Detection & Repair in Covina

Because slab leaks occur under the concrete slab and other leaks happen behind walls, pinpointing the source without damaging your flooring or walls has been a challenge. The development of electronic leak detection equipment enables our technicians to find the exact location of the pipe damage without causing any damage to your home.
Our Covina slab leak detection experts will trace the path of the pipe to determine the exact position of the leak and use trenchless methods for pipe repair.

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
Be sure to contact our team of professional plumbers right away to provide a repair before further damage occurs.
Give us a call at (626) 774-7167 for fast, reliable slab leak detection and repair in Covina or nearby. You may also schedule an appointment with us online.
