I live in a basement flat.
My landlord had builders in to complete damp course as one of the bedroom walls was in a very bad state.
That was a year ago.
I dropped something down the back of the chest of drawers this morning, and, when pulling it out, to my absolute horror found that the back of the piece of furniture was literally covered in (what looks to me like) white mould spores
I've now emptied that side of the room and moved my daughter in with me.
Does anyone have any experience with this kind of thing?
I'm very worried about it and don't feel happy to put my daughter back in there until it's sorted out.
I've googled and found suggestions as to how to treat the piece of furniture, and will do my best to get the right stuff to be able to do that tomorrow but I know it's likely to take them a while to get the builder back to take a look at it.
Please feel free to tell me if you think that I am overreacting- I can take it! 
Any thoughts very welcome.
Thanks.
