Disintegrating layer of wood below siding

These pictures are taken looking upward towards the house. You can see multiple layers, from the outside -> in : the aluminum siding, a lighter layer of wood, a darker orange layer of wood, and a third layer that sits on top of the concrete foundation. The dark orange area is crumbling into sawdust and disintegrates on touch. There are void areas that are totally unfilled - those areas of house are extremely cold. Three questions : How do I properly fill those void areas? How do I properly replace the darker orange layer? How screwed am I? This obviously seems like a job bigger than a few cans of spray foam. submitted by /u/Southern-Office-2638 [link] [comments]
