Document the condition
Note location, timing, weather relationship, changes over time, and any previous work. Photos and simple measurements can improve the first conversation.
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
Slab moisture, contamination, cracks, joints, surface profile, temperature, cure time, UV exposure, and traffic determine whether a floor coating bonds and performs. The written scope should explain the preparation and verification that will no longer be visible at completion.
Compare complete scopes
Look for protection, access, materials, permits, testing, cleanup, restoration, 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.
