Burning logs or coal produces soot and under the wrong conditions can also produce tar and creosote , these stick to the walls of your chimney or flue and restricts the flow.

The restricted chimney will reduce or stop the draw, in severe cases causing the smoke to come back into the room.


As well as creating a large amount of smoke incomplete combustion will create Carbon Monoxide, which is toxic.


This is why you need to have your chimney swept regularly, to remove all deposits.


We recommend a Carbon Monoxide detector is always installed in the room of the fire or stove.

Current recommended frequencies for sweeping are 

Wood - quarterly

Smokeless fuels - at least once a year

Bituminous Coal - at least once a year

Oil and gas - once a year

We are based in Bricket Wood, with easy access to the M1 and M25, so we can easily reach, St Albans, Waford, Radlett, Hemel Hempstead, Redbourn, Harpenden, Hatfield and other parts of Hertfordshire and beyond. So don't be afraid to get in touch for a no obligation quote.

The cowl above is a gas fire cowl that was used on a solid fuel fire. This was so blocked the smoke spilled out of the fire back into the room, filling it with smoke.

Always get your fire or stove installed by a HETAS registered engineer.
