St. Marks Lighthouse 1842; oyster town. Gulf of Mexico exposure + freeze risk 8–14 nights/year (Panhandle climate distinct from peninsula). The dominant 1900s–40s frame + 1950s ranch + military-era modern 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 Wakulla County with same-day diagnostic visits.
Four repair pathways calibrated for St. Marks
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.
