What is a Chimney Crown?

A crown or wash serves as an important function on your chimney.  The crown is designed at a slopped angle which directs any accumulated water away from the top portion of your masonry chimney and flue(s).

What is the difference between a crown and a wash?

A crown differs in that it is formed and poured on the top of the chimney and than extends out passed the brick. A wash is usually just cement sloped down from around the flue tiles (or liner) and feathered to the edge of the brick.
Both a crown and wash share the same goal, and that is to encourage the weather elements away from the chimney.  Some might be surprised to hear that many sources of water problems stem from a faulty crown!
