Log Home Problem – Rot on Bottom of Posts

Rot at the bottom of posts is common on log home decks. Many log homes have decks supported by log posts, either fully or partially supported. The bottoms of these posts are vulnerable to rot. If you are considering building a deck onto your log home, here’s one idea to help you prevent rot.

Preventing Post Rot

The key to preventing rot at the bottom of posts is to provide adequate airflow under and around your log columns or posts. This is the best way to protect log posts from wicking up water and eventually rotting. Using kiln-dried cedar logs for posts is another way to prevent rot, as cedar is the most rot-resistant wood for posts that are directly exposed to the weather.

Though this mulch may look nice, it holds moisture up against the log and can contribute to the log rotting.

Protecting Your Log Home for the Years to Come

A well‑built log home deserves protection from the ground up, and addressing rot at the bottom of support posts is one of the smartest investments you can make. By prioritizing airflow, choosing naturally rot‑resistant materials like kiln‑dried cedar, and incorporating preventative measures such as stand‑off bases and borate treatments, you dramatically extend the life of your deck and structural posts. Small choices—like avoiding moisture‑trapping mulch—add up to big gains in durability. Taking these steps now ensures your log home stays strong, beautiful, and safe for decades to come.
