I live in a 1960s bungalow. It has brick outer and inner walls, plaster rendered inside.
In an one corner area of the bedroom, where 2 outside walls join it tends to turn slightly mouldy along the skirting board and wall. The heads of the nails holding the shirting board have tuned rusty and are wet! There are no other sign of wettness.
I am convinced that it is 'striking cold' in an area of the room where the air doesn't move much. Additionally I believe that the damp course in this area may have been damaged due to there being a horizontal 1mm crack along the outer course of bricks (10th row up) running along about 8 foot. This crack has been there at least 20yrs and has not widened.
My question is! Would drilling a series of 5mm holes to the cavity wall and pumping in expanded foam help to solve the matter?
