Our staircase goes straight up the middle of the house (as opposed to, what I think is more usual, an outside wall). Consequently, there is a join between supporting walls downstairs, and the thin walls upstairs. I've tried, over the years, to make a smooth filling between the two, but eventually, it gets more uneven and visible over time. Can someone suggest the best way to deal with it? Next thing I'm likely to try is expanding foam, but is there anything better, or a completely different approach (like putting a strip of wood in, and turning it into a 'feature', instead)?
