McLean slab leak

Slab leaks are the single most consequential plumbing failure across your city. The combination of slab-on-grade construction (the dominant your city foundation typology from the 1940s forward), aging Type L copper supply runs encased in concrete, decades of mineral-laden local municipal water, and salt-air corrosion on coastal properties produces sustained your city slab-leak patterns.

Slab Leak Repair methods · McLean

Repair pathways calibrated for McLean

PEX-A reroute over slab cut wherever possible to preserve original terrazzo, tile, and historic finishes. McLean's 1950s–90s colonial + townhome + newer subdivision housing stock calls for 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.

Mid-rise mandatory
