How Much Does Slab Leak Detection and Repair Cost for Homeowners?

Slab leak detection and repair costs are set after an on-site evaluation, and Wilbur’s provides upfront pricing before any work starts. The biggest cost swings come from where the leak sits under the slab and how we can access it safely.

We’ll use advanced leak detection methods, including thermal imaging, pressure testing, and sound amplification, to pinpoint the source, then recommend repair options such as opening the slab, rerouting, or trenchless solutions when appropriate. Our licensed plumbers handle these projects around Helena and the greater Birmingham area with video verification after repairs. New customers can take 10% off their first repair (up to $100).

Key factors that drive price:

• Detection only vs. detection plus repair scope
• Access method (small slab opening, reroute, or trenchless lining/replacement)
• Pipe length, material, and number of tie-ins affected
• Post-repair video inspection and any code-related corrections
