Mould that keeps coming back in 1 corner of our room

I too had this problem, in my bedroom on the bottom of a north facing wall. And you can get rid of the mould. Ive also painted 6 inches of the wall with damp proof paint. To be honest this didnt really help. What did help though is a dehumidifer running in the room. With or without the heating on i ran a dehumidifer in there everyday. I open the window at night on the latch, when the dehumidifier is off(or you could turn your heating on and leave the dehumidifer running whilst your asleep and shut the window ( if you can sleep through it running, i tried this once and it dried my throat out), so i prefer to have the heating on with the window on its latch which is imprtant as it ventilates the room. Then when i wake up i shut the window and switch the dehumidifer on straight away and then switch off again before work on a work day. Ive continued this routine in the colder weather and so far no mould has grown.
