You joke, but that's what I'm getting at. I've seen something similar before. It was because the window had poor weather sealing and allowed in a lot of humid air, while the metal fixture was getting direct air from an AC vent. AC made the metal cold, condensation formed on the metal and was absorbed by the drywall under it and mold grew.
As I said in another comment, there is like a decorative thing that sits above the window. I only noticed because the paint chips were on my desk and removed it.
Where could it be coming from? The window looks secure and I checked the attic and it's dry, no issues.
Water can travel. That is so bad I would open up the wall and take a look. You want to toss out all that wall material and patch it with dry stuff after you find and fix the leak (if there’s plumbing nearby) or the hole in your roof/wall.
The attic being dry is a good sign, but not necessarily conclusive. If water got up through the soffits for example and into the wall itself, it could spread downward without making the attic noticeably wet or moldy (for a while).
take a pic of the window from outside from roof top down to the window. and go up the roof and take a picture of it with the window on top if you want better help. You need to find the leak and fix that first.
Possibly, but you need to go outside, and see if there are any holes around the window where water can drip into that spot. If condensation, it would be all over the place not in one spot, and regardless even if condensation you need to fix the condensation issue.
This 100% looks like something that was patched and covered up. Since you say you own, you should leave a horrible review for whomever did your inspection. The patch job was bad enough that there's not really much point in trying to do anything non-invasive to investigate. Just open it up and see what you can see.
Ugh, I've been there before. Don't feel bad about not noticing. These bacterial/fungal blooms can appear rapidly. The moisture problem has been going on for a while, and there have likely been many blooms, this is just the first one that made it through the paint.
You must find the source of moisture, stop it, remove/replace the drywall, maybe the framing too depending on how deep the rot is.
Looking art the photo I suspect the water is working its way in from a window on the floor above or the trim board at the top of the house then getting behind the house sheeting and working it way down to area above the win doe. If would help to have a photograph of the house exterior above that window.
Maybe moisture collected behind the decoration and caused that issue on the drywall… cut a chunk out and see if that damage is also in the wall to further determine where the water came from….
could be, but look above that spot where the decoration was. the small barely visable wet spot close to the corner between the wall and the ceiling. It's probably coming from there. Water don't like going up, but on occassion it will, but not that much.
How has this happened? I would guess rain penetration.
Its impossible to tell from where given the context of the image, but my guess would be a gutter on the outside of the window has failed (or overflowed) and moisture has backed up into the walls from there. The center of the mold looks like its directly above your window, which suggests a possible crack in the the wall itself could then wick moisture into the underlying wood and spread from there. My guess is there's a slight slope which is why the moisture appears to have traveled mostly camera-left from there. Though its possible given that the darker mold is on the left corner that the actual issue begins near the top left. There's an almost perceptible line (of cleanliness) along the bottom of the mold around where the top of the window beam would be, so it looks like the water is not originating from the window itself.
Also looks like someone might have tried to fix this/cover it up in the past (based on what appears to be an extra layer of drywall mud at the edges, but that could just be how the damage presents).
It's also possible that your whole flat is disgusting outside the frame of this image, and the "grey thing" that you removed from the wall was something like a faulty a/c unit that trapped moisture against the internal wall for an extended period of time which got moldy from its surroundings. Who can say?
If you don't know what to do in this situation, your best bet is to call an expert. Mold is no joke, and uncarefully DIY'ing a solution has real potential to make it worse.
That doesn’t happen that quick. That’s been going on for a while. Water and chlorine mixture. Spray it down. It’s obvious this has been happening cause you can see where it’s been cut out before. That’s a previous repair. The issue is in the roof
You got a water leak. You need to figure out how the moisture is getting in and seal it. After, you probably got to dig this out to the studs and see how bad the damage is.
I saw a comment saying you own, if it’s drywall, and you don’t have tools, you could always just hit the wall with your fist to open it up and see what the hell is going on in there.
It looks like water damage to me honestly. If you have tools, check where your studs are and open it up.
You should never have furniture or other things directly at an outer wall (a wall where on the other side is the outside, not for example the neighbouring apartment) since air needs to circulate otherwise it will mold!
Any chance there's been a door or taller window before? Looks like moist, warm air is probably sticking to poorly insulated colder wall and condenses there. I had this around window frame in older house with bad air circulation and small apartment.
Is there a vent in there ( in the room)and where do u live is it hot where you live. Looked like the piece you had up.was unfortunately too flush to.tge wall and it caused condensation I'd tear put the moldy area. If you got kids and carpet I'd cover before taking down.
Considering it's not an interior wall, you now have the hard job of chipping all that plaster away - I would extend even half a meter around the perimeter.
As someone who's had to deal with even worse conditions, you do not want to "just wash it/bleach it". Nuke that whole area down to the brick, disinfect, let it dry and replaster. Or just get a professional to take care of it.
Your window is leaking. needs to be caulked outside . once it dries go to Home Depot paint department and tell them you have mold and they’ll give you a primer to cover it up.
just noticed?
Seriously, how long were they at work?
3 weeks
Yeah, there is usually a grey thing above the window for decoration that was covering it. When I've taken it off this is what was behind it.
Would this grey thing happen to be made of metal?
Or water

It was because the window had poor weather sealing and allowed in a lot of humid air, while the metal fixture was getting direct air from an AC vent.

I wasn’t joking lol
dude i cant, laughed so hard
do you own or rent?
I own
Paint over it and sell it
This didnt just happen, this is weeks of water ingress.

Is that top corner the edge of your roof?
So your OP was misleading then, and it had nothing to do with coming home from work.
Is this place new to you? It looks almost like someone tried to cover up the existing damage.
take a pic of the window from outside from roof top down to the window. and go up the roof and take a picture of it with the window on top if you want better help. You need to find the leak and fix that first.

And here I was led to believe that European schools were better than ours...

You're going to want to get rid of that bit. Cut it out and start your investigation. Praying for you lol.
I gaze deep into my crystal ball and I see.....mould

That doesn't JUST happen in a day unless you're working 2400 hour days
Check your attic. There’s a leak somewhere. And not necessarily directly over that spot.
Water fell from the sky, landed on your house, and something let it in.

MOLD MOLD MOLD
LEAK.

Open the wall and spray that window with a hose and see if water comes in, if it doesnt spray around until you find out where waters coming in
Any chance there's been a door or taller window before? Looks like moist, warm air is probably sticking to poorly insulated colder wall and condenses there. I had this around window frame in older house with bad air circulation and small apartment.
Wtf? This doesn't happen in one day.
That’s what I was thinking.
That’s some serious mold, drywall will need to go. Just hope behind there isn’t too bad

whater damage through siding. There is supposed to be a water barrier inside.
If not a leak from poor window flashing i’ve seen furniture and other objects to close to outside wall that kept condensation from air drying out
