A chimney liner plays an important role in the safety and efficiency of your whole system. This inner portion, made of clay, cement, or metal, keeps the combustible elements inside from damaging your chimney and causing a fire. It also allows the smoke and carbon monoxide to safely vent outside your home.
Unfortunately it may become necessary to have your chimney relined at some point. Here are seven common reasons why this may need to happen:
1. Moisture Damage– Moisture can enter your chimney through repeated cycles of freezing and thawing. Over time this can cause cracks in the clay liner or flue tiles. For example, you may notice pieces of broken tiles in your firebox-a sign that all is not well up inside.
2. Deterioration– While chimney liners are meant to last a long time, even well maintained liners begin to deteriorate with age!
3. Lightning Damage– Clay tiles have advantages, but a lightning strike can heat them up quickly and make them expand, causing them to crack. If your clay tile lined chimney is the unfortunate casualty of a lightning strike resulting in fire, a relining is definitely in order! Often a stainless steel liner is recommended as a replacement.
4. Improper Installation– A liner that isn’t installed properly the first time won’t be able to perform properly and can cause major problems in your system. As a matter of fact, faulty chimney liners are a major cause of chimney fires.
5. Flue resizing– Replacing your furnace with a new one may mean that your liner may not be the proper size. Relining with a different sized flue will help solve the problem.
6. Change in fuel type– If you’re making a change from one fuel type to another (for example from gas to wood), it’s important to note that some liners aren’t compatible with all kinds of fuel.
7. No liner at all– Believe it or not, some older homes may have chimneys that have no liner at all! If your home was built before 1940, that may very well be the case.
