Thanks. The house had a DPC in 1992, the installer has since gone out
of business. the main walls affected are internal or on the party wall
with the neighbour. doing the outisde may also be tricky because the
wall contrcution is stone dressed brick.

Cladding? - this should not have bridged the DPC when it was applied, if it
has you may need to double drill from inside.

presumably the new dpc would need to go abpve the concret e floor but
below the suspended timber floor? also, is it best to avoid the bricks
that have already been injected?

Is the concrete floor the same level as the wooden floor? - if it is then
keep the same course all the way around, if you can get underneath the
wooden floor easily enough and there is suitable access, then do underneath
the wooden floor, but where the concrete floor starts, you will need to step
it up so that it joins onto the course you will be drilling above the
concrete, like this:

Wood V :...............
