Hello!
It seems that a basement wall (the one the basement stairs are attached to) is resting on a wooden sill, which in turn is embedded in the concrete floor (house from '39).
Concrete, basements, and organic materials are not ideal even if the wooden sill looks fine upon visual inspection. What to do?
Best regards,
LArs

Hello Builder & thank you for a detailed response that I still don't quite grasp...
I understand it as I should open the compartments between the standing wooden studs and there remove the sill and replace it with a new one that is wedged. But then I haven't cut the studs and therefore have a piece of sill left in the floor....just where you point out that it is important to wedge. Somewhere I have a mental block and need help sorting it out..

Yes, thank you, it's "just" that I only have two standing studs, one where the stairs begin and one where they end. The other studs are placed crosswise with nailed paneling on both sides. The stringer is then nailed to this wood paneling. For me, this means that the entire stair load is evenly distributed across the sill via the paneling.
This might mean that the stairs "hang" on the panel if I cut the wall a bit from the floor?
The "length" of the stairs is about 2.5 measured on the floor.
What is a karlssonkil? I understand that they are meant to create tension between the floor and the new sill. Building trade?

Thank you Builder for your comments. Here is how I do it...
Build up a new foundation as a stair landing that meets the underside of the stringers with a sheet in between to avoid organic contact with the stone foundation, even though it's faaar from damp areas. I'll have to come up with a good way to create tension against the stringers. Now the stair stands on a solid base.
Then I cut the wall 10 cm from the floor, remove my wooden sills, and reseal the channel. After that, I place the wall/corner posts in a number of adjustable post shoes that I screw to the floor so that I can secure them tightly against the floor. Then on with the drywall...
It feels like it’s going to work...
