Slab leaks are a Florida signature problem — most homes here sit on a concrete slab with water lines run beneath it, so a pipe that fails under the slab hides until the signs surface inside.
Act now — this one damages the home while it waits. A warm spot on the floor, the sound of running water with everything off, or unexplained moisture can signal a slab leak. Left alone it undermines the slab and grows mold, so it's worth confirming quickly.
Common causes:
• Decades-old copper or galvanized lines under the slab corroding through — common in Florida's older slab-built homes
• Abrasion where a pipe rubs concrete or rebar as the house settles over the years
• High water pressure stressing buried joints until one weeps
• Aggressive soil and water chemistry eating at metal pipe from the outside
• A jackhammer-the-slab quote before the leak has been located with proper detection equipment
• No discussion of re-routing the line overhead as an alternative to breaking the slab, which is often cheaper and cleaner
• Pressure to sign a big repair before your insurer has been contacted
• No state license number for plumbing work
What are the signs of a slab leak?
A warm or damp spot on the floor, a water meter that creeps with everything shut off, a sudden jump in the water bill, or the faint sound of running water in the floor. Any one of these earns a professional look.
Does insurance cover a slab leak in Florida?
Many Florida policies cover the resulting water damage and the cost to access the pipe, while excluding the worn pipe itself — and terms vary widely. Read your policy and document everything before repairs begin.
Slab leak detection & repair: $1,500–$7,500 (typical ~$3,500)
Wide range by design — includes detection; access under finished floors and rerouting vs. a spot repair dominate the cost.
