Pool and Spa Leak Detection in Pike Creek Valley
Summer heat and wind can evaporate a lot of pool water, so it can be hard to tell normal loss from a leak. A bucket test compares evaporation to actual water loss. We then pressure test plumbing lines and use dye testing around lights, skimmers and fittings. Finding the leak safeguards the pool shell and the soil around it.

PEX and Copper Pipe Leak Detection in Pike Creek Valley, DE
Whether your Pike Creek Valley home has modern PEX plumbing or traditional copper pipes, leaks can occur. We are proficient in detecting leaks in all common piping materials found in Delaware homes. Our tools are designed to work effectively with both metallic and non-metallic pipes, so no matter your plumbing system, we can reliably locate any leak. We handle everything from pinhole leaks to joint failures.
Irrigation and Yard Leak Detection in Pike Creek Valley, DE
Drip and sprinkler systems are a common source of hidden water loss in most yards. A cracked lateral or a stuck valve can waste thousands of gallons before anyone notices. We test the irrigation system separately from the house and trace leaks along buried lines. Many water providers recommend checking irrigation first when bills spike in summer.
Water Leak Detection in Walls & Ceilings in Pike Creek Valley, DE
Water leaks behind walls or in ceilings can go unnoticed for long periods, leading to extensive drywall damage, wood rot and mold. We use non-invasive methods like moisture meters, thermal cameras and borescopes to precisely pinpoint the source of these leaks. This approach minimizes the need for destructive investigation, saving you time and money on repairs to your home's interior.
Gas Leak Detection in Pike Creek Valley
Gas leaks are extremely dangerous and require immediate professional attention. GNV Plumbing provides rapid response gas leak detection services using highly sensitive detectors to identify even the smallest gas leaks in your home or business. We prioritize safety and will work quickly to locate the leak, advise on necessary repairs and make sure your gas lines are secure and up to code in Pike Creek Valley.
Hidden Wall and Ceiling Leak Detection in Pike Creek Valley
Leaks inside walls and ceilings often show up as stains, bubbling paint, soft drywall or a musty smell. We use thermal cameras to spot temperature differences caused by water, then confirm with moisture meters. Acoustic tools help when the leak is on a pressurized line. Pinpointing the source lets us cut a small, neat access opening.

Main Water Line Leak Detection in Pike Creek Valley
The service line between your meter and house can leak underground for months, especially in older galvanized or copper lines. Wet spots in the yard, unusually green grass or a sinking area near the front of the house are clues. We use line tracers to map the pipe and ground microphones to hear the leak. That keeps excavation to a small, focused hole.
