I've been working on an addition to my house.
We are keeping an existing fireplace with a brick chimney. I have already framed around the chimney but still need to have the existing chimney extened about 5 feet.
The chimney used to be outside the house but will now be enclosed. Is there anything special I need to do with the chimney itself?
I've heard that I need to demo down to about two feet of rebar before adding back upward. Is this true?
Is it possible to frame a new chimney made of wood built ontop of the existing chimney?
