The chimney flue is an essential part of your chimney that affects its overall safety and performance. Any damage to the chimney flue, but most especially cracks, can cause safety hazards to your home. That said, you should repair the chimney flue before using your chimney again.

 

 

What Is a Chimney Flue?

Also called a chimney liner, the chimney flue is a pipe-like lining that helps your chimney operate safely. It offers a range of benefits like heat protection, corrosion protection, toxic gases protection and optimal efficiency of the chimney.

What if the Chimney Flue Has Been Cracked?

Any damage to the chimney flue can result in various safety issues. Some of these include:

• Fire – If there is woodwork adjacent to an unlined chimney, this can catch fire in just a span of three to four hours. The same thing could also happen if your chimney flue is cracked or has deteriorated.
• Corrosion – Without a chimney liner in good condition, acidic materials in flue gases may penetrate brick and mortar. This can cause the mortar joints to erode quickly and the exterior masonry to be exposed to moisture. Over time, this may lead to chimney collapse.
• Toxic Gas Leaks – Hazardous gases can leak into your home interior if you have a cracked chimney flue. Even the smallest openings in the liner can enable toxic fumes to penetrate your home and endanger everyone inside.
