The most common slab leak symptoms in a home are unexplained changes in water use, new floor or foundation changes, and persistent moisture or musty odors. These usually point to water escaping beneath the concrete slab, where it can migrate and show up away from the actual leak.
Our plumbers use specialized equipment to quickly pinpoint slab leaks and then repair by accessing the line through the slab or, in some cases, rerouting water lines outside the concrete. We handle these issues routinely across the Coachella Valley, and repairs may involve careful jackhammering to reach the source when rerouting isn’t the better path. A trenchless pipe liner can be an option on some piping to seal leaks and restore service with minimal disruption, and 24/7 emergency help is available when water is actively spreading. One practical tell we see in the field is moisture that returns after mopping, even in dry weather.
Shut off your main water valve if moisture is spreading and call a licensed plumber for diagnosis.
