How to treat damp patches on my outside wall of bungalow

We have had for many years black damp patches and faint damp spots moving upwards in our bungalow for years, on the front bedroom outside walls mainly. It is a 1930s bungalow and the dining room often smells musty. We have put stuff on these areas, which goes in two corners also, but has not cured it. Not sure if is samp or just condensation as the windowsI had put in a few years ago probably are not good and have made problems worse.
