Crown cracks letting water into the flue
Why it happens here
Crowns crack from freeze-thaw cycling and from being built too flat or too thin. In Franklin Commons, many crowns on older homes near Commons Center were built without a proper overhang, so water sits on the crown and works its way into the flue.
Our approach
We chip out the failed crown, rebuild it with a proper slope and overhang, and apply crown sealant. That combination sheds water instead of absorbing it, and it lasts far longer than a patch.
