An active hot-water slab leak beneath a concrete foundation in Santa Ana costs $350 to $650 to pinpoint acoustically, and $1,800 to $4,200 to resolve via an overhead attic PEX-a reroute. Non-invasive acoustic listening sensors and FLIR thermal imaging isolate the pinhole rupture without jackhammering or destroying finished hardwood and tile flooring.
