Slab leaks are a San Antonio problem more than a plumbing problem. The soil under Universal City, Texas is expansive clay over the Blackland Prairie, and ground that moves takes buried copper with it. We find the leak in Universal City before anything gets cut, then price repair against reroute.
What drives leaks in Universal City is decades-old cast-iron drains under slab foundations. It is why a warm spot on the floor or a hairline crack in the tile deserves a call rather than a wait-and-see — under-slab leaks do not stabilize on their own.
If the same line has leaked before, a repipe usually beats another patch. Homes in Universal City that are mostly 1960s through 1980s military-era construction often reach that point, and we would rather tell you now than come back in eight months.
