August is slab leak season in North Texas and it's not a coincidence. The clay under your house dries out and shrinks, the slab shifts a little, and the copper line running through it doesn't shift with it. What you'll notice is a warm spot on the floor, or the water bill jumping for no reason, or the sound of water running at 2 a.m. with every fixture off. We locate it with electronic equipment before anybody starts breaking concrete.
