Cracked chimney crowns letting water into the flue
Why it happens here
Cedar Ridge freeze-thaw cycles crack crowns faster than most homeowners expect. Water sits in hairline cracks, freezes overnight and widens them. After a few winters the crown is failing and water is running down the inside of the chimney.
Our approach
We pour a new crown with chimney crown mix, proper thickness and overhang, then seal it with ChimneySaver water repellent. A correctly built crown should last 20 years or more in Cedar Ridge.
