Note the condition clearly
Track location, timing, weather relationship, and prior work. Photos and rough measurements make the first conversation go further.
Read the local context
Columbia combines historic in-town homes, postwar brick ranches, military-influenced neighborhoods, and fast-growing suburbs. Humid heat, intense thunderstorms, clay and sandy transition soils, mature pines, and rolling watersheds make moisture and runoff important.
Ask what will be hidden
Humidity trapped in the substrate, chalking, failed caulk, and long hours of direct sun determine the real preparation and coating plan. A written scope should explain the prep and verification work that won't be visible when it's done.
Weigh whole scopes, not totals
Check protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranty, and change-order terms.
What official local sources add
Columbia provides historic-preservation guidance and a municipal stormwater program. Local designation, flood and drainage conditions, easements, and permits should be verified before exterior, structural, or site work begins.
Checked in 2026, flood zone, historic-district status, and permitting still need parcel-specific confirmation with the City of Columbia.
