Asthma and mould in rented property

[As9019]

Hi all,

Sorry I wasn't sure where to post this.

I currently rent and have done for a long time. I've been in this house for 3 years. It's an old house and slowly it's been getting more and more mould.

I rent from a family member and it's difficult because I don't really want to complain. But I have asthma that's not well controlled and was hospitalised yesterday. They specifically asked if I had mould in my house - I actually I had no idea it could be triggering my flare ups.

I've tried over the years cleaning it off as that's what my family member has suggested but it just comes back again. I've a window open in my bedroom most of the year to try keep air circulating.
Our bathroom doesn't have an extractor fan so it's there but the main problem is my bedroom where it's up the sides of the walls by the wardrobes (you'd have to move the wardrobes to clean it), it's on the windowsills and bits on the walls.
Thankfully the living room is okay, it's mainly upstairs that's the issue.

What can I do? I plan on asking my family member to help me sort it but I've no idea what will actually sort it or what I should be asking for.

Would a de humidifier or something help?

Thanks

I would move to a better house/flat. Not worth risiking your health.

Doesn't sound like your cleaning enough- a few times over the years?
One of our bedrooms has a hard to fix issue with blown render and if I leave it, the walls get mouldy. I wipe down with vinegar/ mould cleaner once a week and haven't had any mould since I started that routine. If you leave it it will grow and spread. It takes 2 minutes.

Open all upstairs windows for 10 minutes every morning and bathroom window for 20 after every shower- we also don't have extractor fan at the mo.

How do you dry laundry? If you're hanging it inside then you definitely need a dehumidifier or you're making the house damp.

Thank you so much @RabbitsEatPancakes that's really helpful.

If it's behind the wardrobes are they against a void exterior wall? Change where they are. Heat the room more as well as ventilate. And yes a dehumidifier will help too. Our house gets mould appearing and it's a constant battle to stop it taking hold. We are all out at work school so can't ventilate well in the morning. The kids are crap at opening curtains and blinds so the windows get mould on. The bathroom fans are useless so the bathroom ceiling gets spots on periodically. I spend way too much time scrubbing with mould spray and wiping up condensation.

I have my upstairs windows open a tiny crack, these are the very small upper middle ones within the whole unit all year round 24/7. A few minutes a day isn’t enough I’m afraid, I know it’s cold now and your house could just be more susceptible but keep them open as much as possible. We dry all washing indoors and have never had a mould issue.
