Signs of a Slab Leak and Why It’s Urgent

A slab leak is a plumbing failure that occurs beneath a home’s concrete foundation. Because the leak is hidden, the damage can build for weeks or months before homeowners realize what’s happening—making early recognition and prompt repair especially important.

While the exact cause varies, most slab leaks involve aging water supply lines, shifting soil, corrosion, or plumbing installation issues. The urgency comes from the fact that water can travel through the slab and surrounding materials, undermining both your property and your indoor air quality.
