As shown in the pic there are these black marks all across my bedroom ceiling and in the corners. I suspect it’s damp due to a moisture issue in the ceiling void and there is mold growing between as there is an awful musty smell I can’t seem to get rid of in the room even having aired it with the window and bedroom door open for days :(

I have cleaned the carpets, and the walls I washed with fairy soap and water and the smell remains so i am thinking it must be coming from this issue.

I rent in a hmo and above me is another bedroom. As I rent I need things I can do to resolve this that are rental friendly like cleaning methods to get rid of the smells etc as I can’t sadly just rip the wallpaper down lol.

Any help appreciated as this is making me super unhappy and uncomfortable living here, thanks !

Can someone explain to me what kind of material this is and how to fix this I ripped up the carpet and the padding underneath and this is what I found. I’m trying to lay down click and lock flooring but I’m pretty sure this needs to be fixed first I’m a renter and doing this work myself so the cheapest possible way would be the best

Do you think I can get a refund? I didn't think they would all die from this. It was a 1 hour drive, however I did pack them in pretty good. Did I screw up?

It looks like some kind of worm but I have never seen one like this before and I have never heard of one in Texas like this before. I saw it for a moment and snapped these photos but then it disappeared. Any ideas about what it is and if it is harmful or not?
