Tonight I found dark mould growing on the wall of my bedroom where my bed is. It's an outside wall, the flat had a damp problem before I moved in (but was only told it was in living room, not bedroom, and was now fixed with a damp-proof layer inside the walls). My bedroom has always smelled of damp although I've never been able to see it.
I bought a dehumidifier, have the vents on my windows open permanently and open the windows fully several times a week. I don't dry washing inside my room. The last time I pulled my bed out was early January and I didn't see any mould then.
Coincidentally I also haven't been able to shake a cough this year, I've picked up various viruses from the children I nanny for but the cough hasn't gone away in between. I thought it was just viral but not sure if the mould will be contributing to this.
I've now moved my bedroom around so my bed is against the internal wall near the door and will be emailing my landlord tomorrow.
Any advice on what to say to/ask him and also how best to clean it off would be greatly appreciated!
