For hard-to-find leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach.

Sewer line issues under a slab can also look like slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations.

Cold Water Slab Leak Detection in Florissant, MO
Cold water slab leaks do not create warm spots, so they are harder to see. They often show up as a running water meter, damp carpet, a musty smell or water seeping at baseboards. We isolate the cold side and use acoustic equipment to listen for the leak through the slab. Line tracers map the pipe route so we know where to listen.
