Poor air circulation?

[LooPrEvil]

In preparation for decorating a bedroom I moved a free standing wardrobe that was against an external wall.

Once moved, unexpectedly I found a mould like substance on the wall, starting at the skirting board and going up for about 2 feet. This had lifted the wall paper from the wall in that area.

A friend thinks it is caused by poor air circulation due to the positioning of the wardrobe and suggests I reposition it against an inner wall.

Does anybody have any views on this please?

Also, I am planning on having cavity wall insulation in the next few weeks, will this have any impact?

Thanks.

Lack of air circulation is part of it, but the real answer is that the air in your home contains too much moisture.
This is easily solved by increasing ventilation, not drying clothing inside, using extractors in the kitchen and bathroom etc.

Placing the wardrobe on an inner wall may help, as the inner wall is likely to have a slightly warmer surface than the outside one. However this won't remove the cause of the problem, and it is likely the mould will return elsewhere.

Cavity wall insulation won't make any difference to this problem.

Thanks Flameport.

Cavity -wall insulation may make a difference to this as the inner skin will be warmer and may therefore be at a temperature where condensation will no longer occur and mould may no longer form.

Moving the wardrobe will help improve matters.

Thanks MW, that is what I am hoping for.
