Causes of Chimney Liner Damage and How to Fix It

Since a chimney’s flue liner is responsible for protecting combustibles from extremely hot temperatures, its overall condition is a critical safety concern for homeowners. In order to keep your home safe, it is important to know the different factors that cause the lining to deteriorate and require repair or replacement. A general construction company reveals more below.

Common Causes of Damage to Flue Liners

A dilapidated flue liner is alarming because it can start a house fire. Be on the lookout for the following causes of flue liner damage in chimneys.

• The subpar construction of the chimney.
• The corrosive byproducts of combustion. Since flue gases are acidic in nature, they can speed up the decomposition of mortar joints.
• The incorrect size of the lining for the appliance. This can cause an excessive amount of creosote buildup. When mixed with moisture, creosote can accelerate the failure of the flue lining.

How to Repair a Damaged Flue Liner

When you see broken pieces of masonry in your fireplace, make sure to call a home remodeling contractor or chimney technician to inspect the condition of the flue liner. It is also important to schedule annual inspections since damage to the flue liner is not always obvious.

The main concern is that damaged tiles are extremely difficult to repair and may even require the partial tear-off of the chimney to accomplish. While a simple repair is possible, is it not a cost-effective option. When it does not make sense to patch up a damaged liner, then replacement is likely due. A new chimney flue liner will not only need fewer repairs but your masonry will also be protected from damaging emissions.
