True or False: Posts in contact with soil should be pressure-treated.

Posts that are in contact with soil should indeed be pressure-treated to resist decay and insect infestations. Pressure treatment involves infusing wood with preservatives under high pressure, which greatly enhances its longevity and durability, especially in environments where it is prone to moisture and ground contact.

Wood that is in direct contact with the ground is at risk for rot due to moisture absorption and is vulnerable to termites and other wood-destroying organisms. By utilizing pressure-treated wood, homeowners and builders can ensure that such posts withstand the harsh conditions posed by soil and other environmental factors, thus reducing the frequency of replacements or repairs.

This precaution is vital for structural integrity and safety, particularly in residential construction where posts may support decks, fences, or other outdoor structures.
