Conditions dictate the approach
Salt air and humidity make the hidden layers, sheathing, the water-resistive barrier, window flashing, and clearances, matter more here than almost anywhere else, regardless of the finish material chosen.
What a complete scope spells out
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration

Charleston context
Salt air is the variable that makes coastal cladding different, and it works on the parts nobody looks at. Airborne salt accelerates corrosion of fasteners, flashing and any exposed metal in the assembly, so a wall can fail at its attachments and its water management details while the visible surface still looks sound -- which is why material compatibility and fastener selection carry more weight here than appearance does. Wind-driven rain is the second force: in this climate water arrives horizontally, so the water-resistive barrier and the flashing behind the cladding are doing the real work, not the cladding itself. The building stock then sets the constraints. Historic masonry and frame buildings in the older districts may be subject to review of visible exterior changes, and raised Lowcountry cottages put much of their wall area in exposed positions that take weather directly.
