I have a brick chimney with 2 clay flues and I will be doing some repair on the crown soon.
What do they usually put between the inside of the chimney and the outside of the clay flue to hold it in place?
This chimney was rebuilt about 10 years ago by the previous owner and it is in very good condition except for the crown.
I am also very comfortable doing this work myself.
#1 - If you don't know what you're doing - get a licensed electrician!
#2 - If you follow my advice and something bad happens see # 1
Electricity bites hard, and it could be the last thing you feel... Good Luck!
