What is Chimney Relining?

Chimney relining is the installation of a new flue liner. Homes require the service of chimney liners in North Wales or elsewhere because most types of liner or flue deteriorate with time and become a hazard to use at a fireplace.


A functional chimney liner sustains home safety by protecting people inside a house from carbon monoxide poisoning. It also prevents the chimney and the home from catching if exposed to intense heat and embers.


Why Chimney Relining Is Important?

Uneven and large liners create a poor draught that causes blowback of smoke into a room. The way to stop smoke from blowing back is by chimney relining. It is also common for old chimneys in a bad state to leak fumes, especially when the flue is not lined. Over time, hot smoke, acids, and tar destroy chimney walls, erode mortar joints, and cause staining on brickwork or exterior stone. Dilapidated flue also allows harmful fumes to leak into the property.


Liners are essential as they help in channeling heat and gases through a chimney top. They also block heat, making combustible materials around a chimney to catch fire. Chimney relining should happen before using a fireplace if a liner is crumbling or cracked.


It is why chimney inspections and cleaning should happen regularly to monitor the condition of chimney liners and remove combustion by-products before they build up.

Nowadays, chimney professionals can use special cameras to inspect chimneys. You can ask to see a live image of damage when a chimney professional sees it and recommends chimney relining.


How Frequent should Chimney Relining Happen

A chimney liner is essential. How long does it last, and when should you replace it?


Ceramic and clay liners should last for 50 years. Metal flue (stainless steel) liners are expected to last for 20 years and even longer within proper maintenance.

However, the expected lifespan of a liner does not guarantee optimal performance for that long.


Various factors affect the period that your flue liner will last in good condition.

  • Natural wear and tear

  • Exposure to severe weather conditions

  • Effects from unplanned forces of nature

Regular cleaning and inspections help to increase the life span of a liner. Chimney cleaning in the Philadelphia area and other regions should take at least once a year. Annual camera chimney inspections help identify liner problems early when you can organize for repair before extensive damage happens to the flue system or the chimney.
