Chimney liners are used to protect the inside of a masonry chimney from wear and tear caused by wet conditions. Moisture, over time, will cause decay and corrosion of mortar, clay, and brick liners.

In colder climates, this moisture will freeze, expand and then thaw, thus causing chunks of the chimney to break and crumble.
