How the visit works
- Prove there is a leakMeter isolation tells us whether water is escaping and roughly how fast, before anyone starts opening things up.
- Split supply from drainA pressure test on the supply side separates a pressurized leak from a drain or roof issue - they look identical from the ceiling stain.
- Listen and imageAcoustic equipment finds pressurized leaks under your area slabs and behind tile; thermal imaging maps the wet area.
- Mark the spotWe mark the exact point and show you before any cutting is authorized.
- Repair or rerouteSpot repair where access is reasonable, reroute overhead where a slab repair would cost more than it is worth.

Questions about leak detection
How accurate is slab leak detection?
On a typical North Carolina slab we normally get within a foot or so, which is the difference between one small opening and a room of broken concrete.
What does leak detection cost in North Carolina?
Most residential detection in North Carolina runs $250 to $525 depending on square footage and how much of the system has to be isolated. The fee is credited against the repair when we do the work.
My bill doubled but I see no water. Where is it going?
Under a slab, into the ground on the service line, or through a running toilet flapper. We test all three - and the toilet is the cheapest possibility, so we check it first.
Can you find a leak under concrete or landscaping?
Yes. Line tracing and correlation equipment work through concrete, soil and pavers, and we mark depth as well as position.
Should I repair the slab leak or repipe?
One failure in a young system is a spot repair. Repeated pinholes in the same North Carolina house usually mean the pipe is failing everywhere and a repipe is the cheaper answer over five years.
