We've just bought a house with an open fire and chimney, which we know were used by the previous owner. I'm aware we need to get it swept. What does this involve, how long does it take, and is it messy?
Also, our survey said we should get the flue "checked" to see if the flue lining is decayed. Is this something a knowledgeable chimney sweep will do anyway as part of the sweeping service, or do I need to ask for it as an extra service?
