Document the condition
Note where it's showing up on the Charleston property, when it began, any tie to weather or tides, how it's progressed, and prior repair attempts. Photos and rough measurements make the first conversation far more useful.
Read the local context
Charleston includes historic masonry and frame buildings, raised Lowcountry cottages, postwar suburbs, and coastal infill. Flat low terrain, tidal flooding, hurricanes, salt air, wind-driven rain, high water tables, and persistent humidity make drainage and drying potential central.
Ask what will be hidden
Moisture testing, contamination, crack and joint condition, surface profile, cure temperature, UV exposure, and traffic all carry extra weight in Charleston, where tidal flooding and salt air work on a slab year-round. Once the coating cures, nobody can check the prep work again, so the written scope needs to spell it out in advance.
Compare complete scopes
A complete Charleston scope addresses protection, access, materials, permitting, testing, cleanup, the restoration itself, exclusions, warranties, and change-order rules.
What official local sources add
Charleston administers historic-preservation review and floodplain management in a low coastal city. Local district rules, current flood maps, elevation, drainage, wind, and salt exposure can materially change a project scope.
