Can anyone suggest how we can resolve this damp issue?
Box bedroom on 1st floor, south west facing corner. 1970's semi with cavity wall (no cavity wall insulation) when there is driving rain we get this damp patch on the wall after about 4 hours of rain. We have re-sealed around the pvc glazing, also around the concrete window ledge, the drip channel is also clear under the window ledge. We have also painted weatherguard over the pebbledash. Guttering is sound - no leaks. There are no obvious cracks in the pebbledash and it appears to be sound, not blown. No pipework in the wall. We are at a loss.
Thank you.
