If the damp mould or wet patches on the walls are higher than 5 feet, or even wet walls upstairs, this indicates that the outside walls have lost their weatherproofing qualities and are now letting water into the wall, which is coming into the house and causing problems.

If you cannot see the damp or diffused moisture, then it is best to investigate by looking behind furniture, at the back or wardrobes, and anywhere the walls inside feel damp or wet, or maybe where the paintwork inside is flaking away or becoming powdery.
