Tips on dealing with wall/ceiling joint damage

[Packlam]

Hi

We have moved into a house built in 2006 and almost every room has issues with the intersection between the ceiling and the walls. The worst room is my youngest son's bedroom and I have attached some pics.

It looks to me like the tape was stretched too far when the original plastering was done and now anything attached to that tape has some away.

Any tips on dealing with this neatly would be awesome as there are many many areas like this.

Many thanks in advance

Paul
