A masonry chimney lasts a long time, but not forever. Moisture, frost and decades of fires wear on the masonry. The good news: a chimney rarely needs to be rebuilt – it can usually be renovated from the inside.
Signs the chimney needs attention
Common warning signs are poor draft, a smell of smoke in the house or attic, damp patches on the chimney stack, frost-damaged joints, or remarks from the chimney sweep at inspection. A leaking flue is a fire hazard and must be fixed before you keep using the fireplace.
Flue liner – flexible and proven
The most common method is to feed an acid-proof steel liner down the existing flue. The liner creates a completely sealed channel, suits most stoves and boilers, and is usually installed in a day without touching the masonry.
Slip casting – preserves the flue area
In slip casting, a ceramic compound is drawn up through the flue, giving it a new, smooth and sealed inside. The method works well when the full area of the flue needs to be kept, for example for open fireplaces.
Sometimes a steel chimney is the right answer
If the masonry is in too poor condition, or you want to place the stove where there is no chimney at all, a modern steel chimney is often the best solution. See our range of chimneys.
