Sheralds Croft - condensation and damp

I'm working with residents in Sheralds Croft who as tenants of Scambs are having problems with damp and condensation in their houses, especially against the walls in some rooms. I've had some informative replies from the team at Scambs, but I think we will need to have a site meeting so that we can understand what is doable and what is not. Part of the problem is the deasign of the houses - going back 30 or 40 years - and the changes in heating systems since then. This isn't a winter to be having these sorts of problems though.
