What Is a Slab Leak — And Why They’re So Common Here
A slab leak is a break in a water line running underneath your home’s concrete foundation. Left alone, it quietly runs up your water bill, warps flooring, feeds mold, and can eventually undermine the slab itself. Southwest Florida is one of the worst regions in the country for them — and it’s not bad luck. It’s geology.
The soil here is sandy, shifting, and sits over a high water table. It moves as groundwater rises and falls, stressing buried pipe until it cracks or pulls apart at the joints. On top of that, the region’s hard, mineral-heavy water corrodes copper and metal supply lines from the inside out. Add aging polybutylene and early copper in homes built through the 80s and 90s, and slab leaks happen here far more than the national average. McGrath Plumbing has spent 20+ years finding and fixing them — without tearing your house apart to do it.
Signs You Have a Slab Leak
Spiking Water Bill
An unexplained jump with no change in usage is the #1 slab-leak red flag.
Warm Spots on the Floor
A hot-water-line slab leak creates warm patches on tile or laminate you can feel underfoot.
Running Water Sound
Hearing water move when everything’s shut off usually means it’s escaping under the slab.
Low Water Pressure
A buried leak bleeds off pressure before it ever reaches your fixtures.
Cracked or Buckling Floors
Water pushing up through the slab lifts, cracks, and buckles flooring over time.
Mold or Musty Smell
Constant moisture under the slab breeds mold — often the first thing homeowners notice.
