Emergency Slab Leak Detection in New Martinsville
A sudden drop in water pressure, visible dampness or the sound of running water can signal an emergency slab leak. GJK Plumbing offers emergency detection services in New Martinsville to address urgent situations quickly. We prioritize rapid response to limit water damage and prevent further structural compromise to your property.

Water and Sewer Line Slab Leaks in New Martinsville, WV
Slab leaks can affect both freshwater supply lines and sewer drain pipes. Our detection services are set up to identify both types of leaks, which present different challenges. Sewer line leaks often involve foul odors and slow drainage, while water line leaks can appear as wet spots or high water bills in your New Martinsville, WV home. We have separate methods for each.
Thermal Imaging for Slab Leaks in New Martinsville, WV
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 significantly without any physical disruption to your property in New Martinsville.
Electronic Leak Detection in New Martinsville
For elusive leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach. This technology allows us to locate leaks in many pipe materials, including copper, PEX and PVC, commonly found in New Martinsville homes. It helps prevent exploratory digging, saving you time and money.
Leak Detection for Older West Virginia Homes in New Martinsville, WV
Many older homes in New Martinsville, WV have copper or galvanized steel pipes that are more prone to corrosion and leaks over time. Our technicians are highly experienced in detecting leaks in these older systems, understanding their common failure points. We provide expert analysis for the challenges presented by vintage plumbing under concrete slabs.
Post-Tension Slab Leak Detection in New Martinsville
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 safely or recommend a reroute that avoids the slab entirely.
Slab Leak Repair Through Direct Access in New Martinsville, WV
When a single leak is found on otherwise healthy pipe, direct access can be the most economical repair. We cut a small opening in the floor at the marked spot, repair the pipe and pressure test it. Then we patch the concrete and leave the area ready for flooring. Accurate detection keeps that opening as small as it can be.

Video Pipe Inspection for Sewer Leaks in New Martinsville, WV
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 important if the issue isn't a pressurized water line, helping us determine if a sewer line repair is needed instead for your New Martinsville home.
