Thanks for the replies.... Even the funny one :RpS_thumbup:
Defo cannot dig out as the back of the house runs along a rural lane on a bank. Its a lower elevation from the front & the Damp is showing on the interior walls that's technically under ground level from the rear.
Does not smell of Damp inside so my Quote entails Remove all plaster from ground floors and remove rubble, Tank walls floor to ceiling Â£5600 plus VAT.
Im thinking of hiring a Damp meter myself and checking out the readings, but im being told that's its better getting a pro company in rather than having a go myself??
