Slab Leak Repair in Florida

Signs of a slab leak

• A warm or damp spot on the floor — the classic hot-line symptom.
• Water meter spinning with every fixture off.
• The sound of running water inside walls or floors.
• Unexplained spikes in the water bill (check your meter first).
• Cracks in flooring or baseboards, mildew smell, or low hot-water pressure.

If water is actively surfacing, shut off the main and follow the emergency steps first.

How detection works

Specialists isolate the hot and cold systems with pressure tests, then listen through the slab with acoustic equipment and sometimes thermal cameras. Good detection pinpoints the leak within a couple of feet, so any concrete work is surgical. Expect $150–$600 for detection — it is money that saves jackhammer time.

Repair options

• Spot repair ($500–$2,500) — open the slab at the leak and fix the pipe. Right for a first leak in younger piping.
• Reroute / repipe the line ($1,500–$4,000+) — abandon the under-slab run and bring it through walls and attic. Right for repeat leaks or aging copper.
• Epoxy pipe coating ($2,000–$6,000) — lines the inside of existing pipes where conditions allow; less common for pressurized supply lines.

Why Florida homes get slab leaks

Hard water corrodes copper from the inside, sandy Florida soil shifts and abrades pipes from the outside, and water chemistry in some counties accelerates pinhole leaks. Homes from the 1960s–90s around Bradenton, Sarasota and Tampa are the prime candidates. If your home has had one slab leak, treat it as a warning about the rest of the system, not bad luck.
