How Slab Leaks Occur
A slab leak takes place when a pipe beneath the concrete slab of your property or building develops a leak. Most of these leaks can be a result of:
-
Aging or corroded pipes
-
Sub-standard installation and/or construction issues
-
Shifting soil or foundation movement
-
High water pressure or temperature fluctuations

Since the water leak is hidden under concrete slab, the signs will usually be subtle until major damage occurs.
How to Know if You Have a Slab Leak
Be wary of these common signs:
-
Unusual spikes in your water bill
-
Damp spots or warmer places on flooring surfaces
-
Fractures in walls or flooring
-
Noise of running water specially when no faucets are on
-
Mold or mildew smells
-
Very low water pressure
If you notice these types of signs, do not wait! Early detection is key to preventing expensive repairs and maintenance.

-
Foundation damage: Repairing a foundation can cost thousands of dollars
