I have been reading the various posts about damp in cold spots and inside wardrobes and would appreciate further advice on how to fix our problem. Basically, we sleep in a large bedroom (7m x 4m) in a semi-detached house with 3 external walls. Lately, there has been increasing smell of dampness in the room and the wardrobes in the corner of the room always seemed to feel cold when opening it, so started removing clothes from the wardrobes to discover all the wifeâ€™s shoe boxes were damp and the shoes were covered in mould and mould was on the back of the wardrobes on the hardboard back. After removing the wardrobes we discovered black mould on the two walls. One wall has only paint on it which when removed the bare plaster is dry and without mould, the other wall with wallpaper is covered in mould, but the plaster does have a little but more importantly is wet. We have a air vent /grill immediately above the wardrobe height which I covered with cardboard the last few months believing the cold air was coming from there, which caused light mould in wardrobes previously. There is no mould above the wardrobe height to the ceiling and we have had new double glazing put in with open trickle vents and have an additional air vent on the other side of the room kept open.
There is skirting board on the walls so there is a gap between the wardrobes and walls but bendy walls does mean parts touch.
Now, with a baby we are concerned about her health and would appreciate some practical steps we can make to solve the problem more permanently. We are thinking of covering the two solid walls with thermal boards and plastering over it to remove the coldness from the walls? any other ways to deal with the cold corner so that it can cope with the condensation, central heating behind the wardrobes wouldn't be practical?
I will try to post links to some pics to illustrate the situation.
Just an update, I have kept the wardrobes away from the walls and there isn't any cold air / breeze around that area no more. I pealed back the wallpaper last night the expose the wet plaster which has tried out this morning. I have uploaded some pics to the following location. Would isulating the wall and fitting radiators behind the wardrobes be overkill?
The problem you seem to be having is one of condensation. This is occurring because the moisture filled air in your room is moving into the cooler areas of the room (in and behind your wardrobe) and cooling. Cold air cannot hold as much moisture as warm air and so the moisture in the air is condensing. When this occurs you need warm dry air to be able to dry the condensation. If this is not available, or cannot sufficiently reach the condensation then mould will grow.
The solution here is to try reduce the moisture in the air by changing the moisture filled air for fresh air. i.e opening the windows etc.., allowing any air to reach the affected areas i.e move the wardrobe well away from the walls preferably to a location near an internal wall, or if this is not possible then why not insulate behind the wardrobe.
One last thing, you dont dry clothes inside the house do you??
