Problem: Birds in Chimney

Jackdaws love a large open chimney in which to make their nests and tend to do this between April and July. If you have twigs falling into your fireplace and suspect there is a bird nesting in the chimney, then due to the The Wildlife & Countryside Act 1981 you will have to wait until the young have fledged before removing the nest. You will not be able to use the fire whilst waiting. For more information visit the RSPB's website

Pigeons love to explore chimneys and we often get calls from distressed customers with a sooty bird flying around and marking their soft furnishings


Doves have also been known to take a tumble down the chimney stack

Question: How long does it take to remove a birds nest from a chimney? [visit our sister blog]

Birds in Chimney Solution

The Wildlife & Countryside Act 1981 protects wild birds, their eggs and their nests. As it takes around a month for the Jackdaw fledglings to leave the nest, the safest time to sweep the chimney and remove the nest is August time.

You should not use your fire in this time. However, if you keep an eye out and are sure that the birds have left the nest before then give us a call in July.

You should then get a bird guard fitted to the chimney and have any unused chimneys capped off to stop them returning.

Contact us if you have birds in your chimney.

A missing chimney pot will reduce the draw of air for your fire and will stop it burning properly, it will also create an attractive entrance to your stack for wildlife and allow more rain to enter your property.

Problem: Rain in Chimney

If a fireplace and chimney are not used, you may find that you suffer with damp in the chimney breast caused the rain getting into the chimney. It may dislodge old cement in the brickwork and send parging down.

These problems can be eased by preventing the weather from entering the chimney by having a rain cowl fitted or having the unused chimney capped off.
