Before I do my new desk I have to sort out some creaky floorboards
underneath my PC area.
The lengths I had to go to in order to (virtually) stop the creaking,
was to
cut all the tongues from the boards, take up the boards, cover all
joints with gaffer tape and replace. Nothing else worked. The tongues
and grooves were creaking due to warping and shinkage of the wood. Some
creaks remained due to small cracks in the wood, that meant the wood
even creaked within itself. Old dry wood creaks very easily !
