An underground leak investigation covers the private supply route outside the building rather than assuming every unexplained water loss is beneath the slab. A persistently wet patch, meter activity with normal demand off or a pressure change can help define the investigation. Irrigation, hose connections and indoor fixtures may share the supply, so describe the whole arrangement and any recent outdoor work.
Ask how the route and affected section will be established before excavation. Listening, isolation and pressure observations have limitations that depend on the pipe and site. Utilities must be considered before digging, and private services may need separate identification. For a Charlotte Water connection, confirm the ownership boundary using the utility guidance; a leak in a public main requires a different response from a damaged private line.
For a Charlotte-area request, call (323) 916-2854 with the exact address and the symptoms or work you want assessed. Confirm the requested service, assessment charge and appointment availability.

How it works
- 1
Define the affected system
Private-line boundary. Describe the symptoms and the exact property.
- 2
Review the findings and choices
Discuss supply and irrigation separation and the limits of the proposed assessment.
- 3
Confirm the full scope
Agree on availability, price, access, testing and restoration before booking work.
Pricing
The price depends on the assessment, access, pipe condition, materials and agreed work. Confirm charges, exclusions, testing and surface restoration before approving the scope.
