Plumbers in Sunnyslope

A century ago, people came to the slopes below the Phoenix Mountains for their lungs. Tuberculosis patients and other health seekers pitched tents and built small cottages in the dry air north of the city. The neighborhood that grew out of that start is still hilly, still modest in scale, and made up largely of small homes built from the 1940s through the 1960s, most of them poured straight onto concrete slabs.

Slab-on-grade construction puts supply lines under the floor or inside the slab itself. In Sunnyslope that line is often galvanized steel, now well past the age when it starts corroding through. When it does, the water has nowhere to go but into the soil beneath the house. You might notice a warm patch on the tile, the hiss of running water with every tap off, a meter dial that turns on its own, or a bill that climbs month after month.

The expensive mistake is hunting for the leak with a jackhammer. Acoustic and thermal leak detection narrows the spot before anyone breaks concrete, and sometimes the right slab leak repair is a reroute through the walls rather than a trench through the kitchen. To see what waiting would cost, run the hidden leak cost calculator. For how a small leak becomes a large bill, read the $14,000 drip.
