Above what height should wood siding and sill plates be installed above grade?

Wood siding and sill plates should be installed at least 6 inches above grade to ensure they remain protected from moisture, which can lead to wood rot and other deterioration issues. This height helps to prevent water from splashing onto the siding and sill plates during rain or wet conditions, reducing the likelihood of mold growth and structural damage. Maintaining this distance is crucial for the longevity of the materials and the overall integrity of the home. Proper installation height is a standard building practice designed to enhance durability and performance in varying weather conditions.
