The liner inside your chimney serves a few important functions. Firstly, it works to protect adjacent woodwork from catching fire due to the heat moving through the chimney too quickly. Second, liners help to protect the masonry from the by-products of combustion. These by-products have a corrosive effect and can reduce the life of the chimney. The third important function of a chimney liner is to help maintain a proper-sized flue inside the chimney. This helps appliances run more efficiently, reduces creosote build up and prevents the production of carbon monoxide.
In a standard masonry chimney, the flue liner may be made of clay, ceramic or metal conduit. The liner is crucial to create a safe passageway for the flue gases, and it will also help maintain the structural integrity of your chimney. During your annual chimney inspection, we will also inspect the lining and let you know if you need a replacement.
Sometimes, you might see evidence of a faulty liner at the bottom of your chimney in the form of shaling. This refers to thin sections of chimney tile that fall off and pile up at the bottom of the chimney. This is most common with clay tile liners, and if you see it you must call for a repair immediately.
If your lining is in need of replacement, we will re-line the chimney with a more modern lining that’s designed for optimum protection against fire and carbon monoxide leakage into the house. Your chimney liner is one of those parts of your home that you can’t see, but can have a profound effect on the health of your family and the state of your house. Remember, even if your chimney looks fine from the outside, there may be problems brewing on the inside. Call to make an appointment for an inspection today.
