Oldest continuously-occupied European-established city in U.S.; Castillo de San Marcos. Freeze risk 5–12 nights/year on average — most freeze-prone Florida region. The dominant 1880s frame + 1920s mediterranean + 1950s ranch + modern infill construction era determines the failure modes we see most often, and galvanized + type l copper + pex-a as the supply baseline tells us what we'll find behind walls. We respond across St. Johns County with same-day diagnostic visits.
Four repair pathways calibrated for St. Augustine
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 finishesControlled slab cut + spot repair
Where reroute geometry doesn't work, controlled access cut through slab, repair, pressure-test, patch.
When reroute impossibleFull 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 systemsProPress no-flame copper
