Most Mount Pleasant leaks are found by the water bill, because slab construction and large floorplans hide them until damage is already underway.
The one-minute test
Shut every fixture and watch the meter. If it still moves, water is going somewhere. Worth doing before you call anyone.
Found without demolition
Acoustic listening, pressure isolation and thermal imaging locate the failure before anything is opened. In houses finished with hardwood, tile and built-in cabinetry, that precision is the whole value — exploratory demolition here is expensive to repair.
Where they turn up
In post-Hugo builds, at connectors, fittings, hose bibs and irrigation tie-ins rather than in the pipe itself. In Old Village homes, at older supply runs in crawl spaces, where a leak can soak framing for months before anyone notices.
Irrigation is a common culprit
A leaking irrigation line or a failed backflow preventer shows up as a rising bill with no indoor symptom at all. If your usage has climbed and nothing inside looks wrong, that is the first place we check.
