Be Safe - Check your chimney I "swept" a chimney in a modern detached house yesterday and pulled birds nests, leaves and other organic matter that filled up two very large bin liners. Please take a look at your chimney and even if you think yours is clear, try to remember the last time it was swept as any blockage including a restriction of air flow due to build up of deposits from your fire / woodburner etc. could lead to a chimney fire, dangerous carbon monoxide fumes or possibly both, not to mention corroding your chimney liner. I will happily give you any advice over the phone and will offer you a 10% discount in January off a chimney sweep if you mention this post. Thanks.
