What is a Slab Leak?
A slab water leak takes place when a pipe under the concrete slab of your home or building develops a leak. All of these leaks can be caused by:

Damp spots and/or warm areas on flooring surfaces
Fractures in walls or flooring
Sound of running water specially when no faucets are on
Mold or mildew odors
Very low water pressure
If you notice any of these signs, don’t wait! Early detection is crucial for preventing expensive repairs and maintenance.
