Slab leaks in Orlando: signs your pipes are leaking under the concrete

No basement means your pipes may run under the slab — and a leak down there hides for a long time.

Because almost every Orlando home is built slab-on-grade with no basement, a chunk of the plumbing runs inside or beneath the concrete foundation. When a line under there starts leaking, it can hide for months — and quietly do real damage.

What a slab leak is

It's simply a leak in a water or drain line that runs under the slab. Old copper can corrode in our soil; shifting and settling can stress a joint. Because it's under concrete, the water has nowhere obvious to go, so it shows up indirectly before you ever see it.

Warning signs

Watch for a spike in your water bill with no change in use, the sound of running water when everything's off, warm spots on the floor (a hot-water line leak), unexplained damp or buckling flooring, or a water heater and fixtures losing pressure. A foundation that suddenly grows mold or musty smells is another flag.

Why slab homes here are prone to it

Sandy, shifting soil and a high water table put movement and moisture against those buried lines year-round. Add the mineral-heavy water scaling things from the inside, and older slab plumbing has a hard life in Central Florida.

What to do

Don't ignore the early signs — a slab leak only gets more expensive. A plumber can locate it without jackhammering the whole floor and lay out your options, which sometimes means rerouting a line rather than opening the slab. If your bill jumped or you hear water with the taps off, call us and we'll help you find it. While you're at it, ruling out a water heater or drain-line issue is part of the same diagnosis.
