• I keep reading about rubble in the floor voids. I'm in a bog standard victorian/edwardian terrace and, when I lifted the only floorboard I have access to under the stairs, the gap between floorboards and rubble seemed to be about a foot so far as I could see.

    I could see the light from airbricks front and back so they weren't blocked, is this usual, would excavating this a bit potentially help with damp issues?

  • Depends how deep your subfloor void is, and how high the piles of rubble (if any) are in the rest of the void spaces).

    Optimal state is having zero rubble, nice deep void and loads of unobstructed airbricks. What kind of damp issues are you seeing?

  • I guess I'm mainly wondering whether this is actually rubble or the subfloor. I've got damp coming up on an internal hallway wall which I'm struggling to work out why.
