Hi Guys,
Couldn’t pass by without adding. I was a specialist surveyor for 12 years, particularly focussed on dampness and timber decay. I note some of the comments re installing a damp proof course and would point out that the majority of modern damp courses that are added after the fact, are chemical in nature, so can be added if you have the skills to do so.
If you are seeing flaking paint or plaster, this is as a result of ground salts coming to the surface in a process known as efflorescence.Simply brush off if this bothers you but it is a sign of rising or penetrating damp and will not “go away” on its own. The salts themselves attract moisture so will feel damp to the touch.
Condensation - and the associated mould, is something altogether different and is a result of an imbalance between heating and ventilation. This is why you tend to see the mould in unventilated areas such as cupboards or the corners of bedrooms, where ventilation (air circulation) is poor. Adequate heating AND ventilation is required to resolve. Mould should be cleared with a fungicide solution, not bleach. A good quality dehumidifier will also help.
