Some chimneys and flues have a chimney cowl fitted, which are devices designed to help prevent wind blowing the smoke back down into the room below.
They also have a secondary purpose of preventing birds or other animals from making nests in the chimney.
If your chimney has a cowl fitted it should be removed to ensure the whole of the chimney length is swept clean. Most cowls simply lift off or have a couple of bolts to loosen before removal.
Step 2 – Measure your chimney
Measuring your chimney will allow you to choose the correct sized brush needed to clean it.
It is important to get an idea of what your chimney is like because there are many chimney brushes available, including round, square or rectangular, in a variety of sizes from 50mm to around 300mm (2″ to 12″).
Step 3 – Inspect chimney
If it has been some time since the last time you used your chimney, or if you have just moved in to the house, check for animals before you begin cleaning.
Birds and squirrels have been known to make their homes in chimneys, so shine a bright torch down the chimney, and if you find an animal, take steps to have it removed.
Whilst inspecting the chimney for animals it is also a good idea to check to see how much creosote/tar has built up within the chimney. This will determine the type of brush that you will need and the amount of brushing required.
This 200mm (8″) chimney has been reduced in places to 50mm (2″) due to creosote buildup.
When a chimney is blocked to this extent it will require the use of specialist tools and should be done by a professional chimney sweep.
Step 4 – Prepare room
Lay a tarpaulin or dust sheet over the hearth and spread it into the room to protect the carpet.
Take another sheet or tarpaulin and tape it around the fireplace to prevent any soot from entering the room. Shop for Dust Sheets & Dust Covers
Step 5 – Choose right brush
Always ensure you choose the correct brush for the job.
