Slab Leak Repair methods · St. Johns

Four repair pathways calibrated for St. Johns

PEX-A reroute over slab cut wherever possible to preserve original terrazzo, tile, and historic finishes. We default to the least-invasive option that solves the problem long-term.

PEX-A reroute through walls + ceilings

Bypass failed under-slab run with new PEX-A supply through wall cavities, attic chases, or ceiling joists — preserves finishes.

Default — preserves finishes

Controlled slab cut + spot repair

Where reroute geometry doesn't work, controlled access cut through slab, repair, pressure-test, patch.

When reroute impossible

Full PEX-A repipe

When multiple leaks indicate end-of-life supply, full repipe through wall + attic cavities; abandoned under-slab line stays isolated.

End-of-life systems

ProPress no-flame copper

For mid-rise + supertall occupied buildings, ProPress crimp fittings replace traditional sweat-soldering — zero open flame.
