How high above grade should wood siding be installed?

Wood siding should be installed at least 6 inches above grade to ensure proper performance and longevity. This clearance helps protect the siding from moisture and water intrusion that can lead to deterioration, mold, and pests. Ground contact can create conditions conducive to rot, especially in wood products, and ensuring a proper gap allows for drainage and airflow, reducing the risk of damage.

This height is a standard recommendation in building codes and is widely adopted in construction practices to help mitigate potential moisture-related issues. By elevating the siding, builders enhance its durability and overall structural integrity, making it a crucial component of proper siding installation.
