The Leak You Can't See Is the One That Costs the Most

Almost every home around here is built on a concrete slab with water lines running through or under it. When the clay soil shifts, those lines can crack or wear through against the concrete. The leak runs 24 hours a day, softening the soil under your foundation and raising your water bill. 

We use pressure testing and leak locating equipment to find the exact spot, then choose the least invasive repair: a spot repair through the slab, a tunnel from outside, or rerouting the line through the walls or attic so it’s out of the slab for good.

Signs You Need Water, Pipes and Leaks

If any of these sound familiar, the clog is already bigger than it looks.

Warm or hot spots on the floor

Unexpected warm spots on your floor may indicate a leak in a hot water pipe beneath the concrete slab.

Water bill jumped for no reason

A sudden increase in your water bill without higher usage may signal a hidden plumbing leak.

Sound of running water when everything is off

Hearing running water when all fixtures are off may indicate a leak beneath your home’s foundation.

Damp carpet or warped wood floors

Moist carpets or warped flooring may signal water leaking beneath the slab or inside nearby pipes.

New cracks in walls, tile or the slab

New cracks in walls, tiles, or concrete slabs may indicate foundation movement caused by persistent plumbing leaks.

Water meter spins with all fixtures off

If your water meter keeps moving when all fixtures are off, a hidden leak may be wasting water.

FAQ

Drain Cleaning Questions

Why are slab leaks so common here?

Expansive clay soil moves the slab and the pipes inside it. Over time, pipes crack or rub through.

Not always. Rerouting the line overhead often avoids touching the slab at all.

Many policies cover access and water damage but not the pipe itself. Check your policy; we’ll provide documentation.
