Leak detection in Charlotte, NC
Turn off every fixture and watch the water meter's leak indicator. If it moves, water is leaking somewhere. A plumber uses pressure tests, acoustic listening and thermal imaging to find the leak so only a small section of wall or floor has to be opened.

Leak detection for Charlotte homes
Hidden leaks waste water and rot framing before anyone sees them. In dry climates a slow leak can evaporate as fast as it drips, so a stain may never appear. The first sign is often a water bill that jumps between seasons that should match.
For the full guide, including what you can safely do before a plumber arrives, see leak detection explained.

Local conditions
Leak detection in Charlotte: what's different
Slow leaks under Charlotte crawl-space homes can go unnoticed for months, and Piedmont red clay holds moisture that corrodes metal plumbing. A rising water bill or a musty smell is often the first sign.
Homes with water heaters in attics or garages add another leak point. A plumber confirms the leak at the meter, then uses listening equipment and thermal imaging to locate it. Charlotte Water serves the city, while lakeside homes near Lake Norman and Lake Wylie may be on wells, which need a different approach.
