How do I stop my chimney from leaking?

The most common cause of leaks is the flue liner. The liner is the metal pipe that runs up the inside of your chimney. It is held in place by a series of metal rings called “couplings”. These couplings are designed to expand and contract with temperature changes, but over time they can become loose or corroded, allowing the liner to move around and leak.
