Slab leak repair in Miami — pinpoint, reroute, and PEX-A specialists

Common signs in Miami homes: unexplained warm spot on the floor (often the first signal of a hot-water leak under slab), hissing sound near floor level with all fixtures off, sudden water bill increase without obvious cause, mildew or musty smell that doesn't go away, water stains on baseboards or wall bases, low water pressure across multiple fixtures, and visible hairline cracks in terrazzo or tile near the leak path. Any one of these is enough to schedule a diagnostic; combinations are almost diagnostic on their own.

Most Miami slab leak detection visits run 90–150 minutes from arrival to written-scope handoff. We arrive, walk the property with the homeowner, isolate supply zones, deploy acoustic + thermal + tracer-gas as needed, pinpoint the exact failure location, and document everything in a written scope before any repair work. Detection-only visits (no repair) are available where homeowners want to validate scope before committing to repair work.

Often not. We default to PEX-A reroute through walls and ceilings whenever original terrazzo, period tile, or historic finishes need preservation — which is most 1920s–60s Miami homes. Spot slab cuts are reserved for newer 2010+ PEX-A construction with isolated failures, or for situations where reroute geometry doesn't work. Full repipe through wall and attic cavities is the default for older homes; the abandoned under-slab line stays in place isolated.

Florida homeowner's insurance typically covers sudden + accidental water damage from a slab leak but not the cost of repairing the leak itself. The damage to flooring, drywall, cabinets, and personal property is usually covered; the plumbing repair (and the diagnostic) is usually not. We provide complete written documentation suitable for insurance claims — pre-repair photos, scope of work, materials specifications, post-repair photos, and pressure-test documentation. Many of our customers successfully recover damage costs while paying out-of-pocket for the plumbing fix.

Detection-only (no repair): $325–$475 depending on system complexity. Spot repair through controlled slab cut: $1,400–$3,400 plus floor restoration. PEX-A reroute through walls + ceilings: $1,800–$4,500 depending on run length. Full PEX-A repipe of a 1,500–1,800 sq ft Miami ranch: $7,800–$14,500. Architect-attributed historic homes (Morningside, The Roads): $12,000–$19,500. HOA documentation, permit fees, and warranty included; finish restoration coordinated as separate scope.
