We have just had a survey carried out on an old stone cottage in Scotland and it has come back with very high damp level readings in most walls. The house has not been inhabited for over 12 months so I presume there will be an element of condensation? I have had a read of the projects and it seems a possible solution may be to incorporate a plastic membrane to prevent the damp prior to batenning and adding plaster board.
The roof on the property looks reasonably sound but a lot of the sandstone faces are flaking. I presume this will lead to porosity? The silicone spraying from what I have read is a no no as the wall needs to breathe. It seems the best way to deal with the damp is to tankle it from the inside? I can't beleive it will cost £20,000!! any advice would be greatly appreciated.
