Moisture Staining

Modern appliances, whether oil, gas or wood-fired, are much more efficient and most of the heat they produce stays within the building. As a result, there is often insufficient heat in the flue and condensation and moisture will result. If there is not a water-tight liner in the flue, this moisture will bleed through the masonry as shown in the photos below.

Improper liner termination

These photos show the type of damage which occurs when a liner is cemented in at the top of the chimney. Condensation will occur at times in the space between the clay flue tile and the metal liner. If this moisture is not allowed to vent out of the chimney (as a proper tile cover will permit), the flue tile will absorb it and freeze/thaw cycles will break the tile apart.

Damaged flue tiles

The next set of photos show the type of damage found in clay flue tile liners.
