Q. In a 1932 solid brick semi detached 3 bedroom house in the black country what would have been the separator at DPC level?

A. There would have been no 'standard' DPC material at that time but it is likely to be; bitumen felt or poured bitumen or double slate. If the property has timber ground floors, to find out lift a board in the under stairs cupboard next to the electric meter (they are usually short and loose there) and with a torch and mirror look at the mortar course just below the lowest part of the timber floor - usually about eight inches below the floor board level. You should be able to see the DPC.
