Slab leaks in Galveston
Homes from 1960 to 1999 make up 52%, close to the Texas figure of 50%. That ranks 41st highest of the 90 Texas cities we profile. Hot lines under the slab expand and rub against concrete for decades until a pinhole forms.
Leak detection confirms the leak at the meter, isolates hot from cold, then pinpoints it acoustically so only one small spot is opened, or none if a reroute is the better fix.
In Texas: Expansive clay soils in much of Texas move slab foundations, causing slab leaks and cracked sewer lines.
