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.

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?

I did a house similar to what yours sounds like. the dining room floor was old
'concrete' with quarry tiles over it. the 'concrete' had failed and the quarry tiles
were semi mobile. it was possible to lift a few of them off by hand and the house
was listed as being damp. it had a new concrete slab poured over a DPM and
sealed with bitumen. all walls were silicone injected and the bottom yard of plaster
was hacked off, as was/is the fashion. that cured the damp but, with the CH installed,
warped most of the nice old victorian doors.

ya live and learn.
