Slab Leak Detection & Repair

A slab leak is a break in a water line running under a concrete foundation. Shifting soil, corrosion and abrasion are the usual causes. Because the leak is hidden, it can waste water and damage the foundation for weeks before anyone notices.

Warning signs

A warm spot on the floor (hot-water line)
A water bill that jumps for no clear reason
The sound of running water with every fixture off
Damp carpet, warped flooring or new cracks in the floor

What to do right now

Turn off the main water valve if water is surfacing or the floor is wet
Check your meter with all fixtures off to confirm a leak
Note the location of any warm or damp spots for the plumber

What the plumber will do

A plumber uses acoustic or thermal equipment to pinpoint the leak, then either repairs it through the slab, reroutes the line through walls or attic, or repipes the affected section.

What affects the cost

Leak detection is often a separate fee. Spot repairs through the slab, rerouting and full repipes vary widely in price, and flooring repair is usually extra. Pricing is set by the independent provider—ask for the trip charge and an estimate before work begins.

Safety first

Smell gas? Leave the building now and call your gas utility or 911 from outside. Don't flip switches.
Water near outlets or the electrical panel? Stay out of the water and shut off power only if you can do it safely.
Know your main water shutoff before you need it—it stops most plumbing emergencies in seconds.
