We bought our house with vinyl siding in Minnesota. The gap between siding and ground is generally at least 6 inches although in the back where it goes downhill it's much more. I don't see the foundation in the gap, just wood. I'm assuming there are cinder blocks behind it since we have a basement.
On side where the garage is and there is no basement, but still on a slope, you can see the cinder blocks but further along the same wall where the basement starts, the wood starts as well.
Is the wood the expected covering for this gap? It's not painted and is definitely exposed to the elements. Is there something I should be doing to maintain this wood?
Here the gap is more than 6 inches but the wood is touching the ground:
The gap is less then 6 inches in places:
