Chimney flue lining for solid fuel fires

Chimney flue lining for solid fuel fires

Solid fuel fires need an 8” diameter flexible liner.  Sometimes the bends or doglegs in the chimney are not at a 45-degree bend or have something in the flue that restricts the liner from coming down the chimney.  Our fitters have the experience to deal with this.  The images show a hole that was created in the chimneybreast to enable the fitting of the flue to go down safely.

Often chimneys leak at the top of the chimney stacks between the mortar joints.  This can occur anywhere in the chimney.  This is very dangerous and will require that the chimney be properly lined.

Sometimes the chimney looks fine but the mid-feathers inside the flue are breached and smoke is leaking from one flue to another or into your neighbour’s chimney.

Before installing an open fire you must use a NACS registered chimney sweep, they will sweep the chimney and issue a certificate after completing an integrity test.  This certificate of sweeping will confirm if the chimney needs lining.

Testing of flues should be done at least once a year if there is not a liner fitted, to ensure the chimney remains safe.  If the house is old, it is advisable to have the chimney lined, as most period buildings would fail a smoke pressure test.

The second image from the top is of a gather that was very large and was fitted into a inglenook fireplace.  The Inglenook fireplace was very old and required the chimney to be lined by our chimney lining experts.  The diameter looks small, however it is an 8” flue system, so the spigot in the image is also 8” (200mm), it looks a lot smaller as the gather we had made to order was very large to close the inside of the chimney.

Often people will experience either of these things prior to having the chimney lined.

- Chimney smoke leaking into their neighbours house or bedroom
- Chimney smoke coming out of two chimney pots
- Smoke coming into a bedroom
- Smoke coming into a loft space
- Sand and debris, which is original chimney lining called pargeting, coming down the chimney.
- Falling bricks coming down the chimney
