Most Dallas-area homes are built on a concrete slab, with water and drain lines running beneath it. Over time, one of those lines can crack or corrode, and water can seep into the soil beneath your foundation. That’s an under-slab leak, and it’s one of the most damaging plumbing failures a homeowner can face.
When left unrepaired, an under-slab leak erodes the soil beneath your foundation, causing settlement, cracking, and structural movement, which can lead to costly repairs. Cole’s Plumbing has served Greater Dallas with licensed under-slab leak repair since 2001.
