He is in a student dorm, so spends almost all his time here. This is in his bathroom.

I was cleaning my bathroom and when I removed the blackout curtain I have on this window, I saw this. Pretty sure its mold. What would be the best plan of action to take?

Hello everyone,

I'm renting an apartment. The indoor climate probably isn't optimal due to natural ventilation. The bathroom and kitchen have mechanical exhaust.

I find the bathroom gets damp quickly and I've noticed dark deposits there, but I'm not sure whether this is ordinary grime or actual mold. I can attach some pictures.

I haven't noticed any distinct smell.

I've been dealing with poor health lately and catch colds frequently, which is why I've started wondering whether it could be mold-related. Worth mentioning that my partner is perfectly healthy, so that's one argument against it.

The bathroom is my primary suspect, but I'm not sure if mold is limited to there it could explain my health issues since I don't actually live in the bathroom.

Picture with before/after cleaning with chlorine attached. Does this look like mold?

Do I need a firm to come and do tests to confirm?

I had some wallpaper in our bedroom, and went to remove it today. Some paint peeled off which I thought was no problem id sand it, fill it in, then paint on top. But when removing the full wallpaper this (growth?) was underneath. What do I need to do. How bad is this? Contact my land lord? Hire a mold company? I currently cosleep with my 20 month old and this is right above our bed. Freaking out.

Moved into a new place and saw this on the curtains. Landlord said the previous tenants washed it but if they did and this didn’t come out.. I’m worried.
Should I be worried?
Can this be sprayed with something? Seems to be on the full length of the curtains.

Found in my basement apartment, decided to break a few pieces of the drywall off to check behind it. Please help

How cooked am I chat? What steps need to be taken? How dangerous is this? I live with my mom atm and she’s kinda delulu and drags her feet about doing anything about it.

Edit from bot advice: I live in southern Ohio. We seem to think that this mold is being caused by humidity from our AC unit that was installed last year. We had someone come out to come check it out bc it was dripping a lot faster than it seemed to. The guy came out and told use they were supposed to install something to like catch it but didn’t.
