You would be surprised how many people aren't aware how often they need their chimney/flue sweeping. This is a little info that should help. The poster shows the different situations that can cause problems with the burning of your appliance. It can be from a blockage which can be a birds nest or a build up of soot and creosote. These not only cause smoke to come back into the room the fire is located and stain walls but also help carbon monoxide build up in that room. The ultimate result can be a chimney fire which will devastate your home. Make sure you get yours swept for a safe efficient fire to enjoy on those blustery chilly days, Craig & Sophie are a call away from yours.
