I seem to have a similar problem to at least one other forum-goer but seeing as he (Colin) didn't provide more info and his issue was a little different I will explain. Cottage in Scotland of a sandstone and slate construction, problem with gable end wall - internal wall has four damp spots all approx 5" wide, 3" high and at the 6' high level in the wall (high ceilings). We had a DPC 8 years ago but these spots have now appeared only on this wall; the spots also darken/lighten at various points in the day and don't seem to positively react to windows being opened/heating on. There is a chimney breast on this wall but not where the spots are showing. Help!
