I'm renting a (horrible) house and I've had a strip of mould growing along the top of one side of my bedroom wall for a while I'm not sure if it's something I've done that's caused it.
When first I moved in I had to ask them to repaint the window area (on the same side as this wall) because it was covered in mould already (as well as 100 other problems with the house).
It's always freezing even with the heating on but I try to open the window as much as possible and have bought a bunch of those dehumidifer pots but the mould still happened.
I asked the agent for advice after trying all of the above so that it was on record that I didn't just ignore it, they only said 'as per your contract it's your responsibility to keep the property free of condensation'.
I have been drying indoors on a clothes horse however not in my bedroom, just in a spare room where there is no mould and yet it's my room that has it... (I did put clothes to dry outdoors on numerous occasions but there's no fence between ours and the neighbours garden for one, and (until the past 2 days) they were taking several days to dry. I ordered a dri-buddi as an alternative solution but after waiting a month was finally told they were out of stock lol... and now I'm due to move out!).
Given that it's only growing along the the top edge of the outer facing wall and there was mould problems before I moved in, is it a sign of structural issues or have I just not opened the window enough (it's been so cold even with them all closed)?
Thanks! Sorry about the length.
