Wonkee Donkee Cowls require removing prior to the chimney or flue being swept

Step 1 – Remove cowl from chimney

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.

Wonkee Donkee Removing a Cowl prior to sweeping a chimney or flue 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.

Wonkee Donkee Checking for creosote and tar to enable you to choose the correct chimney brush and tools 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.

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.
