    Default Crumbling brick on chimney

    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?

    I think I figured out what this is, would this be brick "spalling" and if it is I guess I have no choice but to replace what I can....

    You are most likely getting moisture behind the bricks. That can be from no cap or a damaged cap on the chimney, or condensation caused by inadequate draft for the hot water heater. A proper sized chimney liner and cap should help resolve the problem.
