Now is the high season for soot falls - where damp soot from fireplaces which have not been used for a few months, or even weeks, gets heavy and is liable to drop into your hearth. And into your room - covering carpets, chairs and everything else with smelly, dirty, black powder. I'm already having to help out customers who've experienced this. It only take one serious rainstorm to tip the balance and down the soot will fall. Please get swept folks!
