Water and Sewer Line Slab Leaks in Union City, NJ

Video Pipe Inspection for Sewer Leaks in Union City, NJ
Sewer line issues under a slab can also mimic slab leak symptoms. We use high-resolution video cameras to inspect the interior of your drain lines, identifying cracks, blockages or separations. This is vital if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your Union City home.
Acoustic Slab Leak Detection in Union City
Our technicians use highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab.

It's particularly effective for pressurized water lines, allowing us to find leaks without unnecessary excavation and minimizing disruption to your Union City home.
Thermal Imaging for Slab Leaks in Union City, NJ
Thermal imaging cameras allow us to see temperature differences on surfaces, which can indicate a hidden water leak. As water escapes a hot water line, it creates a distinct thermal signature on the concrete slab. This technique is particularly useful for hot water line leaks and helps us narrow down the search area quickly without any physical disruption to your property in Union City.
