Probably best to get some core samples of the wall tested for salts

from condensation.

I'm sure it's not condensation, but it could conceivable be
penetration; I have never investigated the cavities to see if they are
full of debris. I guess that clearing the cavities of debris is high
on the list of things to try first, yes?

Have a look on Google Groups to read around on it a bit:

Another good source of info would be the forums at
http://www.periodproperty.co.uk

In any case it would be useful to list all the possible causes of the
damp, find ways of proving/disproving them, then consider the
different solutions out there are and their cost/suitability etc.

Pete, That sounds like a good systematic plan. Thanks. I think that
one reason why the demon damp is so scary and off-putting to buyers,
is that it's so little understood - even by many so-called pros...
