Chimneys and chimney pots give character to historic buildings and are essential features of the skylines of Welsh towns and villages. Yet, all too often, they are neglected and poorly maintained. Whether still in use or not, pay careful attention to the condition of your chimneys, since they can suffer from a range of problems caused by weathering, heating and cooling and even chemical reactions with hot gases. Poor or degraded flashing around chimneys is one of the most common ways that water can get into your home. Since chimneys are almost invariably at high level, consider hiring a contractor if any work needs to be done.
