old house fireplaces ?
We are looking at an old house (1850's) all of the rooms have had the fireplaces boarded and/or paneled over. However up in the attic, I could see either the second floor or the downstair flu-- in the attic there was black ooze coming out between the stonework (cresote possibly it was a very hot day and hot up there)-- As I know nothing about old fireplace restoration-- what is the risk in this flue? I will want to return the rooms to showing the original fireplaces even if I can not use them... just a tad bit worried about seeing the black stuff. (I possibly sound like an idiot but in searching on the internet did not locate info when I did some searches) books (titles), video links and personal experience would be appreciated! Thank you!
