A hidden leak costs a working household in 2 ways. You pay for it on the water bill every day it runs, and you pay for it in worry, because water damage adds up and nobody knows where it's happening. In National City's older homes and multi unit buildings, the signs are easy to miss, like a bill that climbed, a warm patch on a floor, or pressure that's dropped, and the leak keeps running while everyone tries to figure it out.
The first step is finding where it is. Detection equipment can often narrow a leak in a slab or wall down to a limited area, depending on what's leaking and how the building is put together, so you know where the leak is and what it involves. You get the situation explained in plain English, and then you decide what happens next. Each job's approach is the licensed contractor's to choose.
When the search comes up empty, that's a useful result too, because a slab leak is ruled out and the bill can be checked somewhere simpler. It starts with one call, you get straight answers, and the decision about the repair, if there is one, stays with you.
