Piers Finlayson explained :
I have chipboard floors across the upstairs of my house - with the chipboard
screwed into the joists.

These are pretty squeaky and, given we're likely to be soon replacing the
dodgy old thread-bare carpets with decent ones I figure I should fix the
squeaking now before the new carpets go down.

Does anyone know the cause and the fix for this squeaking? Is it simply a
matter of lifting the boards and re-screwing them down firmly, or is
something more involved recommended?

TIA,
Piers

Put extra screws in where it might help - but run a vacuum along all of
the joints and trickle/brush talc in.
