Let the condition set the coating, not the can
Humidity trapped in the substrate, chalking, failed caulk, and long hours of direct sun determine the real preparation and coating plan.
What the scope should include
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration
- Exclusions, warranty terms, and change-order process

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.
