Wood Destroying Organism (WDO) Home Inspection Practice Exam

The recommended distance between the exterior siding and the outside grade should be at least 6 inches. This measurement is important for several reasons, primarily related to preventing water intrusion and protecting the integrity of the building materials. Adequate clearance helps to ensure that moisture does not accumulate against the siding, which can lead to rot, mold growth, and other forms of deterioration over time. It also allows for proper drainage away from the foundation, reducing the risk of water damage and pest intrusion. Maintaining this minimum distance enhances the longevity of the siding and the underlying structure. It also aids in compliance with building codes and best practices for moisture control in home construction and maintenance.
