Not all leaks announce themselves with a puddle on the floor. Some of the most damaging plumbing leaks happen invisibly — inside walls, under slabs, or deep in the soil outside your foundation — quietly wasting water and causing structural damage for months before anyone notices. Barnett Plumbing provides advanced leak detection services for residential and commercial properties throughout Marietta and North Atlanta.
Any one of these can indicate a hidden leak — and several together make it very likely.
Acoustic Leak Detection. Sensitive listening equipment picks up the sound signature of water escaping under pressure, pinpointing the location of pressurized pipe leaks within walls, under slabs, or underground.
Thermal Imaging. Infrared cameras detect temperature differentials caused by water that has penetrated building materials. This is especially effective for slab leaks, as water escaping from a hot water line creates a distinct thermal signature on the concrete surface.
Pressure Testing. We isolate sections of your plumbing and monitor pressure drop to confirm a leak exists and identify which portion of the system is affected.
Video Camera Inspection. For drain line leaks, a waterproof camera travels through the pipe to visually identify cracks, joint failures, and other leak points.
Slab leaks deserve special mention. When a pressurized supply line or a drain line leaks under your concrete foundation, the water has nowhere to go — it saturates the soil under the slab, can undermine the foundation, and eventually works its way up through the concrete. Slab leaks can go undetected for months while causing significant damage.
Early detection and accurate location are critical — because the repair options range from localized slab excavation to rerouting the line through the walls or attic (avoiding the slab entirely). We help you understand the options and their trade-offs.
Don’t let a hidden leak quietly damage your property. Barnett Plumbing serves Marietta, Kennesaw, Marietta, Sandy Springs, Woodstock, Duluth, and surrounding communities. Call (678) 437-1234 for a leak detection appointment — or if you have an active emergency, we’re available 24/7.
