Good advice is offered here in that tracking down the actual cause of damp requires a whole house approach, that the causes may be multiple rather than singular, and that sales based damp-proofers are rarely the best people to seek advice from. I do think it important to add however that not all Chartered Surveyors have expertise in the diagnosis of damp, as many purchasers who have obtained Home Buyer and Building Survey reports will testify. Always worth asking to view previous reports of similar properties so you know what to expect.
