Wood to ground is always bad………………
Not only do termites love to eat wood but water is also the enemy to wood. Wood will wick up water whenever in contact with dirt, soil or the ground. So its not just about the termites its also an agent to allow water into the structure.
The picture below still allows water to wick up after resting on top of the cement. I also consider this to be faulty grade because I can’t see the stem wall or at least inaccessible access.
WE are talking dead wood here not trees. Termites do often eat the dead wood on dead or dying trees but generally leave the tree alone.
Thanks for sharing. It’s good to know.
