Understanding Chimney Flue Damage
Chimney flues play a crucial role in safely venting combustion byproducts from your home. Over time, these flues can develop cracks, gaps, or other forms of damage that compromise their functionality and safety. The good news is that in many cases, a damaged chimney flue can be repaired without the need for a complete replacement.
Common Methods for Chimney Flue Repair
Two primary methods are commonly used to repair the interior of a chimney flue liner:
The Joint Repair System: This method is ideal when only the mortar joints between flue tiles need repair. It involves using a specialized sealant to fill gaps and restore the integrity of the joints.
The Resurfacing System: This more comprehensive approach addresses both mortar joint issues and minor defects in clay flue liners or tiles. It involves applying a coating over the entire flue surface to create a smooth, sealed lining.
