Hello all, New to the board, and have a question.
Our house was built in 1901, we purchased it 4 years ago. I noticed that the brick is getting "bubbles" that will break if touched, resulting in holes. The brick is very powdery when it bubbles out and if sc****d at in the holes.
It looks as if the previous owners may have used a drylock type coating on it. The chimney is only used for the gas hot water heater, as their is not a firplace in the house, uncertain as if there ever was.
What is the cause of this, and more importantly what can I do to fix it?
