Issue and questions about a green chimney stain? First off, if your chimney is green, there is most likely a host of issues with your chimney to begin with. These issues allow water to run freely on the affected area, therefore causing the issue of mold or algae.


Green Chimney Stain


How to Fight/Fix

Typically, a green chimney stain from mold or algae will begin at the top of chimney. More so, whenever bricks is exposed at the top and not covered by a proper concrete crown, the possibility of a green chimney stain is much more likely. Moving to the fix… In cases like this a demolition and pouring of a new concrete crown, most importantly with a 2” overhang, is necessary. This is your umbrella for your chimney and the first defense against consistent water flow through the top of your bricks. More importantly, a proper chimney crown will have a rubberized flashing system that separates the crown from the brick, as well as, provides a water barrier for the brick from any moisture coming above.
