Regarding Efflorescence on Chimney in Attic
Before insulating our attic I would like to know if I should be concerned about a heavy white efflorescence on the bricks of the chimney in our attic. There is no efflorescence on the brick above or below the attic. We live in a 1950’s two story home located in an area with low humidity, warm summers & very cold winters. Thanks in advance for your help.
