Electronic Acoustic Leak Detection in Roanoke
Our team uses electronic listening devices to pinpoint the exact location of a slab leak.

Acoustic Slab Leak Detection in Roanoke
Our technicians use highly sensitive acoustic listening devices to pinpoint the exact location of a leak under your slab.

Emergency Slab Leak Detection in Roanoke
A sudden drop in water pressure, visible dampness or the sound of running water can indicate an emergency slab leak.

We focus on rapid response to limit water damage and prevent further structural compromise to your property.

We provide comprehensive slab leak detection services tailored for residential properties throughout Roanoke.

Repiping After Multiple Slab Leaks in Roanoke, VA
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.
Electronic Leak Detection in Roanoke
For hard-to-find 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 various pipe materials, including copper, PEX and PVC, commonly found in Roanoke homes. It helps prevent exploratory digging, saving you time and money.
Slab Leak Reroutes in Roanoke
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.

Hot Water Slab Leak Detection in Roanoke
Hot water lines leak under slabs more often than cold lines because heat speeds up corrosion and causes expansion and contraction. Signs include warm spots on the floor, a water heater that runs constantly and higher gas or electric bills. Thermal imaging shows the heat pattern spreading through tile or concrete. We confirm with a pressure test and acoustic listening before marking the spot.
