hey Susy
You can buy a paint to go over mould to seal it, but as you say you want to find out why it happens.
Do try and get the room aired every day- could you fit a window lock so it part opens but he cant climb out? Or just open his window and close the door when he isnt in there? Sam's bedroom window (and mine) are open all day every day, and most nights!
I know as well it seems to come when the wall is warm inside at it hist the cold outside, but I dont know how you avoid that!!
