Two patterns are the real tell. The first is a pinhole leak that gets fixed and then shows up again somewhere else along the same run within months, meaning the pipe wall itself is thinning, not one fitting having failed. The second is polybutylene supply line: gray plastic pipe that shows up in a portion of homes built prior to 1995, widely treated as a liability at its fittings. A single leak on its own, even an ugly one, is usually still a repair, not a full repipe.
On a slab-on-grade home, which describes most of central Davie, a supply leak rarely shows up as a puddle. What you notice instead is a warm patch on the tile or carpet, a section of floor that feels off underfoot, or a water bill that keeps rising while every fixture in the house is confirmed off. Those are pressure and consumption clues, not visual ones, and they change how the leak gets located before any repiping decision.
