I'm doing a major overhaul of my living room at the moment and I've noticed some shoddy work that's been done in the past. Most of it is sorted now, but there are a couple of joists that are loose at the point the go into the wall (outer wall) and there is a small amount of damp around them, but more moisture from the air I think?
I'm wondering whether to fill these gaps with expanding foam, or whether to just leave them alone?
