Cracked chimney crowns from freeze-thaw cycles
Why it happens here
Snow sits on the crown for weeks, melts into hairline cracks, then refreezes and widens them. Ridgeview's elevation makes this worse than in the valley. Once the crown fails, water runs straight into the chimney.
Our approach
We chip out the failed crown, rebuild it with a proper slope and a flexible crown mix, and seal the brick with a vapor-permeable water repellent. That sheds water instead of letting it soak in and freeze.
