Start with conditions, not a product
Older galvanized or early-generation plastic supply lines tend to fail gradually—falling pressure, discoloration, or pinhole leaks—well before a full repipe becomes unavoidable.
Build a complete scope
- Which sections are failing versus merely aging
- Routing that avoids finished Old Village interiors where possible
- Material choice for the coastal climate
- Permits and pressure testing before closing walls
- What's excluded and how surprises are priced
Mount Pleasant context
Homes built before Mount Pleasant's 1990s growth boom are the ones most likely to still carry original supply lines, and salt-laden coastal air doesn't do exposed metal any favors.
