If you are using untreated wood siding, how far from the earth should it be?

• A. 18 inches
• B. 12 inches
• C. 6 inches
• D. 10 inches

Answer: (C)

Keeping untreated wood siding at least six inches above the ground is essential because soil moisture can soak into wood that is in direct contact with or very close to the soil, leading to rot, warping, and insect trouble. The six-inch gap creates airflow and allows water to drain away, helping the siding stay dry longer. This distance is the standard minimum for untreated siding, with greater clearance sometimes used in very damp areas or where codes or termite protections require it.
