Find the leak first. Then fix exactly that.
Island homes hide their leaks beautifully. Original walls, layers of history, slab foundations, and salt air that's been working on the plumbing since before the bridge, it all adds up to leaks that announce themselves everywhere except the source. The water bill creeps. A floor feels warm in one spot. Paint lifts near the baseboard. In a condo or a shared building, the stakes climb fast, because a hidden leak doesn't respect property lines, and the neighbor below finds out before you do.
The right response is a search that doesn't wreck anything. Detection equipment listens through slabs, reads temperature through walls, and traces the lines without a single exploratory hole, and the visit ends with the exact spot marked before any repair talk begins. In homes this established, that discipline is everything. Nothing gets opened on a guess. You see the finding, hear the options in plain English, and make the call yourself.
When the search finds nothing? On the island that's good news twice over, once for you and once for the neighbor below. The fear comes off the list, the bill mystery moves somewhere smaller, and the house goes back to being trusted. That certainty is the service, whichever way it lands. It starts with one call, and the rest happens at your pace.
"My bill doubled and they found the slab leak in an hour, right where they said. One small cut, not a torn up house."
