Your chimney liner serves a vital purpose in your chimney system by channeling heat and gases up and out of the chimney and blocking the heat from causing combustible materials around the chimney from catching fire. If you have purchased an older home, your chimney may not even have a liner installed. Older homes did not have the same building safety standards in place as we currently do. If your home has a cracked, crumbling, or missing liner, we recommend not using the fireplace until a new liner can be installed. We have liners in several materials to best suit the needs of your chimney system.
