Questions on sealing off chimney pipe
Had a wood stove that we didn't use and got rid of it. The chimney was the metal type that cut in through the wall and vented out of the roof (not a brick chimney).
We're looking at sealing it off and I want to know what the best way to go about it is for both inside and outside. Inside we would have to cut it back a bit - am I good to just shove some insulation in it, or should we silicone a cap of some sort on?
For outside, is there a cap I can purchase or would I have to fabricate something? Not sure on measurements for the outside as I haven't made the trip up to the roof yet.
