Cold Water Slab Leak Detection in Yakima, WA
Cold water slab leaks do not create warm spots, so they are more difficult 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 exactly where to listen.
Post-Tension Slab Leak Detection in Yakima
Many newer homes are built on post-tension slabs that use steel cables under high tension. Cutting into one without care is dangerous and can damage the foundation. We locate the cables with scanning equipment before any repair access is opened. This lets us repair the leak without risk or recommend a reroute that avoids the slab entirely.

Acoustic Slab Leak Detection in Yakima
Our technicians use highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab. This method involves listening for the faint sound of escaping water, even through concrete. It's particularly effective for pressurized water lines, allowing us to find leaks without unnecessary excavation and minimizing disruption to your Yakima home.
