Chimney Re-pointing Alternatives
The chimney in my house (1911) runs behind walls and is not exposed, and therefore doesn't add to the aesthetic of our house in any way. It simply acts as a flue for the furnace and water heater.
Our second story and attic is gutted and we've noticed that the mortar could stand to be re-pointed within 10 feet of the roof. One of the sides of the chimney runs up an exterior wall, and is nearly inaccessible. When we put our walls back up, the chimney will not be visible. Instead of going through the trouble of re-pointing, I'm considering two other options:
1. Coating the entire chimney with a layer of mortar, gaps and brick faces.
2. Apply foam to the existing gaps and/or cracks.
For the side we can't access, that would have to be foamed regardless.
Does anyone have thoughts or past experiences with either of these two options?
