Is the house detached? I had a problem some years back - and after replastering it still pervaded - it was somehow leaching through from next door - never solved it unfortunately!

Having removed a couple of pendant lights I am left with a hole in the artex - or leaving the ceiling rose in place - can you get flat blanking plates for this? or what do people usually do to tidy it up?
