How much does it cost to fix a slab leak in Miami, FL?
Slab leak repair in Miami, FL typically costs $1,500–$4,000 for a spot repair after detection, with leak detection itself running $150–$400. A full repipe to bypass the slab runs $4,000–$12,000. Detection matters more than repair price: a company that pinpoints the leak electronically cuts a small hole; one that guesses cuts several.
Likely causes
- Copper pipe corrosion — The classic slab leak — pinhole leaks in copper lines under the foundation, common in homes 20+ years old.
- Shifting soil / foundation movement — Movement stresses rigid pipe until a joint or line cracks.
- High water pressure — Sustained pressure above ~80 psi accelerates wear on every fitting in the house.
What you can check yourself
- Confirm it's real: watch the water meter with everything off — if the dial moves, water is going somewhere.
- Check the obvious first: running toilets and irrigation leaks mimic slab leaks and cost far less.
- Call your insurer early — slab leak *damage* is often covered even when the pipe repair isn't.
