For hard-to-find leaks, our electronic leak detection equipment sends a signal through your pipes and measures changes that indicate a breach.

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.

Our accurate diagnosis prevents unnecessary excavation and helps you address the problem before it grows into expensive foundation repairs or mold remediation, protecting your investment in your Pike Creek Valley property.
Electronic Acoustic Leak Detection in Pike Creek Valley
Our team uses electronic listening devices to pinpoint the precise location of a slab leak. These highly sensitive microphones can detect the faint sound of water escaping from a pressurized pipe under your foundation. This non-invasive method helps us avoid unnecessary concrete breaking, saving you time and money on repairs. It's especially effective for copper and PEX lines commonly found in Pike Creek Valley homes.
Repiping After Multiple Slab Leaks in Pike Creek Valley, DE
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.

Thermal Imaging for Slab Leaks in Pike Creek Valley, DE
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 quickly without any physical disruption to your property in Pike Creek Valley.
