Plumber in Garland, TX

If there's a slab-leak capital in the Metroplex, Garland is in the running. The city was built out heavily in the 1960s through the 1980s, almost entirely slab-on-grade, on some of the most expansive black clay in Dallas County. That combination — old slab homes plus highly reactive soil — produces one of the most active slab-leak markets we work in. Garland keeps our detection equipment busy.

Here's the mechanism: black clay soaks up water and swells in wet weather, then dries out and contracts hard during Texas droughts. That constant heave and settle puts enormous stress on the copper water lines cast into the slab, and after 40-plus years those lines crack and leak beneath the concrete. Because the leak is under the slab, Garland homeowners usually notice it indirectly — a Dallas Water Utilities bill that climbs month over month, a patch of warm floor, the faint sound of running water when nothing's on. We use electronic leak detection to find the precise spot, then decide between a targeted access repair and a full reroute.

The copper itself is also reaching repipe age. Original supply lines from the 1960s–70s are now 50–60 years old — right where pinhole leaks start multiplying — so for some Garland homes the smarter long-term move is a repipe rather than chasing one slab leak after another. Garland's DWU-sourced water runs around 300 ppm, so scale compounds the wear on aging pipes and water heaters alike. Ernie's brings the right tools and an honest read on whether you need a repair or a repipe.
