Pinpointing Under Slab Leaks From Lake Highlands to Oak Cliff
One City, A Century of Foundation Types
Few cities present as many plumbing eras in one service area. Lakewood, the M Streets, Winnetka Heights, and much of Kessler Park went up in the 1920s and 1930s on pier and beam with galvanized supply and cast iron waste. The post war wave that built Casa Linda, Casa View, and Lake Highlands moved to slab on grade with copper below the concrete, and Preston Hollow holds both patterns side by side depending on the block and the rebuild. Knowing which era a house belongs to changes where we look first, because a leak under a 1958 Dallas slab presents very differently from one weeping into a crawlspace two miles away.
Tracing Water That Escapes Under the Concrete
Diagnosis begins at the Dallas Water Utilities meter, watching the low flow dial with the house isolated to confirm that water really is moving. From there we separate the hot and cold sides at the heater and run a pressure hold, which usually identifies the guilty line within minutes. Acoustic listening equipment then follows the sound of escaping water through the slab, and a line tracer maps the true routing of the pipe, which matters on remodeled properties where a previous owner rerouted around an addition. Thermal imaging verifies hot side leaks by revealing the heat signature spreading through the floor. Nothing is cut until the location is confirmed and marked.
