I have an internal wall with damp along the middle and I just can't figure out what is causing it. The wall is at right angles to this exterior wall where the dotted yellow line is. I'm 100% sure there are no pipes behind or within this wall. It had some thick plasticy wallpaper covering which has since been removed and has been replastered and decorated. I've checked in the loft and there is no sign of roof leaks and the top of the wall is dry. The opposite side of this wall is bone dry Things I have tried and the reasoning: Ground levels outside were too high and have now been excavated to well below DPC (If ground levels were too high I would expect the bottom of the wall to be damp, not this middle section) Removal of thick plasticy exterior masonry paint. This has been done over the last week or so in preperation for repainting the exterior (using hydrophobic yet breathable Emperor Masonry Paint). My thoughts are that water may have been penetrating the old masonry paint and getting stuck behind Gutters cleaned and checked for alignment ~2 months ago Is there anything else you think I should try or to investigate people can think of? This is an old building so tanking or "modern" techniques like injection are frowned upon by the conservation officer. They also seem to be concentrated on DPC issues which I don't think is the issue given the position of the damp
