What happened to this chimney?
J Chesnut| Posted inGeneral Questionson
We have clients in demo phase who discovered that the exterior brick of the chimney near the firebox and underneath a coat of stucco had nearly disintegrated. The house is a 1935 stucco Tudor style.
There is a great photo at this link:http://www.minnephithouse.com/?p=365
Is this simply a matter of moisture vapor escaping through the masonry over time or is there some chemistry happening here due to the wood combustion?

There are many possible sources of the moisture, including rain, moisture from indoor air, and condensed moisture from flue gases.
