MAJOR STRUCTURAL DAMAGE

$5 - 50K+

One of the most severe consequences of an untreated underground leak is foundation damage. Persistent leaks can weaken the structural integrity of your home's foundation, leading to cracks, shifts, and even potential collapse.

UNDERGROUND WASHOUT

$1.5 - 10K

Leaks can cause underground washout, where water erodes the soil supporting your property. This erosion can create voids or unstable ground, affecting not only the foundation but also underground utilities and concrete slabs.

LANDSCAPE & DRIVEWAY DAMAGE

$1 - 15K

Excess water from underground leaks can lead to the saturation of the surrounding soil, affecting the health of lawns, gardens, and potentially creating cracks in your hardscaping elements like driveways and walkways.
