Slab Leak Reroutes in Wilmington
Rerouting abandons the leaking line under the slab and runs new pipe through the walls or attic. It avoids breaking concrete and often costs less than direct access under finished floors. We typically use PEX for reroutes because it handles heat and resists hard-water corrosion. This option is a good fit when the slab is covered in tile or hardwood.

A slab leak that is flooding floors or causing water to bubble up through tile needs quick attention. We respond quickly, help you shut off the water and isolate the leaking side if possible. That often lets you keep partial water service until the repair. Then we locate and fix the leak.

Frequently Asked Questions About Slab Leak Detection in Wilmington
The cost for professional slab leak detection in Wilmington, DE usually ranges from $250 to $700, depending on the complexity of the leak and the time required for diagnosis. This initial detection fee is separate from any repair costs, which can vary widely based on the leak's location and required pipe repair.
Some homeowner's insurance policies may cover the cost of accessing and repairing the slab leak, particularly if the leak was sudden and accidental. However, coverage often varies, and damage caused by long-term neglect might not be covered. We recommend checking your specific policy details or contacting your insurance provider for clarification.
A water line slab leak involves pressurized fresh water escaping from supply pipes, often resulting in higher water bills, warm spots or the sound of running water. A sewer line slab leak involves wastewater leaking from drain pipes, which usually causes foul odors, slow drains or visible sewage seepage, and is not usually pressurized.
Many policies cover the cost to access the leak and repair resulting water damage, though the pipe itself may not be covered. Coverage varies by insurer. We provide photos and a detailed report for your claim.
GNV Plumbing uses industry-leading brands for our slab leak detection equipment, including but not limited to LeakTronics, FLIR thermal cameras and specialized acoustic sensors. These tools are chosen for their accuracy and reliability in various leak detection scenarios, delivering the best results for your home.
For major slab leak repairs, especially those involving excavation or extensive re-piping, a plumbing permit from the local building department is often required. GNV Plumbing handles all necessary permitting processes so your repair is compliant with local codes and regulations, protecting your home.
Yes. Water leaking under the slab can cause expansive soil to swell or wash away supporting soil. Over time this can lead to cracks and sinking. Fixing leaks quickly protects the foundation.
Common pipe materials prone to slab leaks include older copper pipes susceptible to corrosion from hard water or soil acidity, and sometimes PEX or CPVC if they were improperly installed or exposed to extreme temperatures. Galvanized steel pipes, though less common under slabs today, can also corrode and leak.
