Bought a house with a fireplace in the basement, and had it inspected prior to purchase. I think the inspector missed several places that are worthy of critique. The flue goes from the basement, up to the main floor through an wood framed enclosure, then up through the attic. The clearance going from the basement to the main floor is <2" to a floor joist, and the clearance from the attic to outside is <1". A label on the flue states a clearance of 2" is necessary. Attached are pictures. My question is, how screwed am I when it comes to getting this in a safe condition? Is getting it in a safe condition even practical?
