Would this crack worry you?

[Ilovelana]

I have a crack in my living room wall/ceiling & weirdly I can’t tell if it’s always been there or it’s just appeared/got worse. I live in a top floor roof flat and so the walls are slanted, the crack is in one corner. I’ve just noticed it this evening & so worried I am wondering if it’s something I need to contact the freeholder about as what if it means the roof could come down or something?

I can't tell from the photos, is it somewhere the angle changes? Is it plasterboard?

Have you looked from the outside to see if you can see anything?

Yes, it’s on the (curved) corner of two walls. Here’s another photo taken in daylight

It looks like it is in the plaster and not beyond? If it doesn't follow through to the other side then I wouldn't be worried. How long have you lived in the flat?

Wouldn't worry me at all- it'll be down the line of the plasterboard probably - houses move with the seasons. I'd sand gently and fill. Wouldn't think more of it!

Agree with pp, it doesn't look concerning.

If it hasn't been filled before, I wouldn't worry. Just sand it off and lightly fill.
