My chimney is spalling at the bottom. It runs straight through the middle of the house which is three story's high not counting the basement. I have done brick work in the past for a living.The chimney has been rapped with parsing some time in the past by someone.It cracked and that is how i discovered it. It is mainly on one side,but the other side is not too bad.The bad side is spalling up to about thirty inches. I want to tuck point it,but am not sure how much i can take out at one time without it collapsing.The rest of the chimney is like in new condition.I am sure i need to use type n mortar.Please if any one out there can give me advice on this it would be greatly appreciated. Thank you in advance.I forgot to mention I looked inside the chimney and it looks like the inner wall is in good shape. Thanks again.
