The best bet is to have a qualified chimney professional inspect your chimney annually. He or she will be able to detect the accumulation of creosote in your flue and remove it. Burning your fireplace or woodstove at proper temperatures will also help prevent the accumulation of creosote. Burning at lower temperatures, such as when you restrict your damper opening at night in order to make the fire last longer, allows creosote to form inside the flue of your chimney.
Stainless steel pipe, either rigid or flexible, made for relining flues of masonry chimneys when the original clay liner has cracked or broken. May also be used to create a lining in a masonry chimney that was made without a clay liner.
Protective coverings for chimneys usually made of aluminum, galvanized or stainless steel, or copper. Most chimney caps have a mesh screening that serves the dual purpose of spark arrestor and barrier against animals. Chimney caps also prevent rain from entering the flue of the chimney.
A device installed at the top of a chimney for the purpose of sealing the flue shut when the fireplace is not in use. They are often used as replacements for throat dampers that are installed just above the firebox when a masonry chimney is built. Lyemance and Lock-Top top-sealing dampers are as much as 90% more efficient than throat dampers because they provide a silicone rubber gasket seal rather than metal to metal.
