We have an Edwardian fireplace in our house that we need to remove as we’re knocking through two rooms. It’s lovely and we’d like to move it to another room in the house so I’d like to remove it without damaging. But having dug around in the walls I can’t find out how it’s attached - there don’t appear to be any fixings at the sides like our other cast iron fireplaces. I think this one is slate, though it’s been painted to look like wood. The corbels are loose and wobble around when touched, and I wonder if the round half spheres on them would come off to find screws behind? But I can’t work out how to take these off without damage either- my first attempt has resulted in a small chip. So any suggestions please? Excuse the mess, we’ve just moved in and it’s a bit of a dumping ground.
