Right now my interior chimney pipe is hidden behind a wall and I want to remove that wall and expose the pipe, but the pipe itself is not so pretty.
My fireplace is a wood fireplace with a double isolated chimney pipe of about 10 inchs in diameter.
I'm looking to do something like this :
Those pictures comes from my neighbor's house. He said to me that it was done with plaster.
This is exactly my fireplace, but the chimney pipe is behind a wall right now. How can I achieve this rounded chimney pipe ?
