I've just noticed some newly formed bulges in the wallpaper near a doorway on the first floor bedroom of a semi.
In the adjoining, room a new bulge appears to have formed in the wallpaper covering the ceiling.
I've ripped the wallpaper off, and thought its quite difficult to tell, it appears that at least in the bedroom there appears to be some moisture of the wall.
I've had a look at the pipes running through the loft upstairs but cannot seem to locate a leak of any kind. I've also just had a combi installed, previously with water tank etc.
I'll probably call a plumber. Should i switch the water mains off and drain the system of water in the meantime?
