How do you continue the crown molding around a stone fireplace?

If the fireplace goes to the ceiling I would only place the molding to the edge of the stone. You can fit the edge if the mold to the shape of the stone.

We did not do crown molding around the fireplace. It stops on either side of the stone.

I definitely agree with the others that you should stop the molding at the stones.

Cut back a couple of inches on the molding to the stone then use corner crown to the front of the stone with one piece connecting the corners in the front. If you can see the gaps under fill with white caulk . You can cut the stone with a really big diamond bladed saw maybe?

You still might want to make sure it's not a fire hazard

It looks so unfinished without crown molding. Most people just bypass it because they don't how to wrap the molding around the stone. Here are a lot of photos. Click on a photo and go to the site. I would put crown molding around the fireplace.

It can be glued, but I would ask a carpenter what kind to use. That is what we did with our fireplace

We have a brick fireplace and wanted to continue the crown. Since the crown is angled you can fit furring strips behind the crown. I used 1 X3's to nail the lower edge (wall side) of the crown to. Mark and drill into the mortar, not the stone/brick, to secure the strips using Tapcon screws - this way it can always be patched if you remove the crown.

By reading the last comment about drilling and fastening into the motor. It gave me the answer for my stone fireplace which is 100 years old for finishing around with crown. On the front there are beams running up to the front. So I can nail a nailer strip to the front on the ceiling to the beams against the stones. Then on the sides ( 2ft plus on each side ) I can screw on left & right ends another nailer and run it to the wall and nail the wall ends into the top plate. So I have continues nailer around the top of my some fireplace to attach the crown. Screwing into 100 year old motor is not a good idea. Thanks, it got my mind to solve my problem and I hope this may help others.
