How to fix this chimney flue
I have a chimney with 2 flues that are not in a good shape. Both flues are not used at all - one fireplace was converted to an electric fireplace (not insert, just an electric fireplace), and the second flue was never ever used/set up since the house was built.
I would like to fix this to stop deterioration so that water would not go into the flue?
