I'm trying to install ceiling coving in a four walled room.
I'm encountering two problems: 1) two vertical (floor to ceiling) pipe boxes one in a corner and one on a straight wall and 2) more difficult to solve an old/unused warm air heating vent grill fixed to the wall about about 3 inches from the ceiling.
Removing the vent would leave a book size hole in the wall that would need to be filled and finished and painted. Too much skill and paint matching involved in that. Is there a way of fixing the coving flush over the vent? I think I would have to create a small section of coving just for the length of the vent (about 12 inches) and then trim the depth of the coving by a few mm so that it is flush with the wall when the untrimmed coving is placed around it. I wonder even if I could get the coving flush whether or not it would look silly partly covering a vent.
Actually, come to think of it, as I write this I realise that the pipe boxes may be more problematic than the vent. There's surely no easy way of fitting coving around a pipe box?
