If it has been used but not been swept within the past 12 months, for safety it should be swept as soon as possible. If it has not been used since it was last swept, and the problem of birds nesting can be ruled out (if there is a cage or cowl on the chimney), it could be due to the cold or weather conditions. Please call us and we may be able to give advice on the appropriate action to be taken.
If you think there is a blockage in your chimney, please advise us, or call to discuss the problem. We can remove most blockages and can establish what has happened and advise on how to prevent it happening again.
Since there may be eggs or even hatched baby birds in a nest (which are protected) we will not remove nests during the breeding season (May & June) to ensure that the young have left the nest. For more information and advice, see this link from the RSPB.
