Hi,
I moved into property few years ago and in the bathroom it looks like some of the plaster work around the window has bulged. Its been going on for some time and would like to get it sorted
An unrelated engineer did not believe it was water damage as theres no water near it and the walls dont get that damp it may of been trapped air
I'm hoping its a small fix but i dont know where to start or who i would contact (picture attached)
Any ideas/help
Thanks
