Reason for Lining

There are a number of reasons why an old chimney may need lining.

1. The flue is leaking smoke and fumes into other rooms or parts of the building.

2. Condensates or tar are seeping through the chimney walls causing staining, either inside or outside the building (a common problem with wood burning stoves not fitted correctly).

3. The flue is much too large for the type of fire or appliance being used.

4. The flue is too cold, particularly if on an outside wall, and is not drawing properly.

5. If the chimney was built since 1965, but with the liners fitted the wrong way up, tar and condensate leakage may occur.

6. The old flue surface is eroded and rough, causing frictional resistance to the flow of the gasses resulting in poor updraught.
