Emergency Slab Leak Response in Knoxville
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 some water service until the repair. Then we locate and fix the leak.

Post-Tension Slab Leak Detection in Knoxville
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 without risk or recommend a reroute that avoids the slab entirely.
Repiping After Multiple Slab Leaks in Knoxville, TN
If your home has had two or more slab leaks, the remaining pipe is likely corroded too. Repiping replaces all supply lines with new PEX or copper run through the walls and attic. It is a bigger project, but it ends the cycle of recurring slab leaks. We can usually complete a full repipe in two to four days.
Leak Detection for Older Tennessee Homes in Knoxville, TN
Many older homes in Knoxville, TN have copper or galvanized steel pipes that are more susceptible to corrosion and leaks over time.

Thermal Imaging for Slab Leaks in Knoxville, TN
Thermal imaging cameras allow us to see temperature differences on surfaces, which can indicate a hidden water leak.

Frequently Asked Questions About Slab Leak Detection in Knoxville
Slab leak detection in Knoxville usually costs $150 to $450. Repairs range from about $800 for a simple reroute to $3,000 or more for direct access under finished floors. We provide a written estimate after finding the leak.
Once the slab leak is precisely detected, our technician will provide you with a detailed report and discuss the best repair options. These options may include trenchless repair, re-routing the affected pipe or traditional slab excavation and repair. We will then provide a transparent estimate for the repair work.
Warm spots on the floor, the sound of running water with fixtures off, a moving water meter and an unexplained jump in your water bill are common signs. Cracked tile, damp carpet and mildew odors also point to a slab leak. Call us if you notice any of these.
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.
Karst ground with sinkholes is common in parts of Tennessee, and shifting soil above that rock can break buried pipes over time. Hard water can also corrode copper pipes from the inside. Pipes can rub against concrete or gravel as they expand with hot water, and over time these factors cause pinholes and cracks.
Direct repair works well for a single leak on otherwise healthy pipe in an accessible spot. Rerouting is often better under tile or hardwood and avoids future leaks on that line. We help you weigh both.
Slab leaks can cause serious damage including foundation cracks, soil erosion beneath the slab, mold and mildew growth in wall cavities or under flooring, damage to flooring materials and increased humidity levels. Over time, it can lead to structural instability and major, costly repairs.
For significant slab leak repairs, especially those involving excavation or extensive re-piping, a plumbing permit from the local building department is often required. BGV Plumbing handles all necessary permitting processes so your repair is compliant with local codes and regulations, protecting your investment.
