Knock down an old chimney below roof height, or re-flash/fix?
I have an old, second chimney on my 1881 2-family that is leaking water due to a terrible flashing job. It’s only used to vent the plumbing stack (I think). We believe that originally it was used for a kitchen wood stove.
I received quotes to re-flash it (>$1,000 for copper), but after reading some articles here (Martin’s “Farewell to the Chimney”, etc.) I’m thinking that I should knock it down below roof height and just vent the plumbing stack through the roof. This would prevent tough-to-seal air leaks, as well as conduction loss through the roof. I plan to seal up and later super-insulate the house. I’m afraid if I re-flash it now, I’ll want to just knock it down below the roof height later on to improve air sealing, thus wasting $1000+.
Any thoughts? I live in Zone 5A (West Concord, MA).
Thanks – I appreciate any input,
