Hi all, I was hoping to get some advice about the damp problem we have in our rented flat. It's a top floor flat of a converted 1910s(ish) building, although I believe this part we're in may have been added later. We've been here for 2 years and the problem has been gradually getting worse, the landlord has sent various people to have a look but we're getting little back from her and it's becoming extremely frustrating!
I've attached a few photos so you can see what I mean. The huge patch started as circles like you can see below it, but that has now spread. We have three exterior walls in this room and the damp is only showing on this one. Does anyone know what is causing this? It would be great to have more of an idea ourselves so we can push our landlord to fix it.
If you need any more info let me know, thanks
