After renovating the stairs and laying a new floor, we installed a baseboard to cover about 10 mm of movement space. Unfortunately, we failed to consider and nailed it straight through both the list and the parquet. The floor should, of course, be able to expand and contract, which becomes problematic with this solution. The result is that the floor pushes the list against the stairs, which in turn makes noise when walking nearby.
I will naturally need to pull up the nails again, but how should the small list be attached to avoid problems with tension and noise?
I should also ask how to deal with wall baseboards pressing so hard against the parquet that it creaks when walking? Should I simply remove the baseboards and reinstall them a few mm above the floor? Or is there another trick, like oil or similar?
