If an older Coronado home still has its original water lines under the slab, they were put in when copper under concrete was the standard way to build. Given enough time, those lines can show the classic signs, a warm patch on original hardwood, a bill that jumped, or the sound of water in a quiet house. On an island where any project draws attention, it's easy to expect the worst. Most of the time the process is calmer than people expect, and this is how it goes.
How to approach it is the contractor's call, and detection equipment can find the leak through the slab, so nothing gets opened on a theory. Then the options get weighed with island realities in mind. One is an opening at the leak, if that's the right fit. The other is the reroute, retiring the leaking run and carrying new line overhead, through walls and ceiling space, without disturbing the slab, the floors above it, or the finishes that make the house what it is. Whether the reroute fits a given house is something the contractor decides from what's found.
Which path fits gets decided by evidence and explained in plain English, tradeoffs included, especially what the age of the pipe and a second leak can mean. The decision stays yours, made at your pace, with a licensed contractor performing the work when you say so. In an older home, a careful approach is worth the time.
