At GMT Home Services, we know that whether your masonry chimney is venting a fireplace, wood stove or furnace, it has sections of clay flue tiles stacked to form a protective liner called the flue. This chimney flue tile liner is also called a chimney liner. It is crucial to the integrity and efficiency of your chimney by providing a tight seal to prevent hazardous gases from escaping. However, over time, hidden dangers can develop and compromise both the safety and performance of your chimney. These liners can be made of stainless steel, clay or cast-in-place. Aluminum chimney liners are the most affordable and good for gas or oil appliances, but they may not be as durable as other materials. A damaged chimney liner can be a big safety hazard, such as carbon monoxide poisoning and chimney fires.
At GMT Home Services, we stress the importance of a safe and efficient chimney system. Over time, several things can happen that require a chimney inspection, relining or repairs:
Eroded or Deteriorated Clay Mortar: If left unattended, the clay mortar in your chimney can wear down and become a safety hazard.
Cracked Clay Liner or Flue Tiles: Cracks in the clay liner or flue tiles can allow hazardous gases to escape and compromise your home’s safety.
Flaking or Spalling of Liner Walls: When the clay on the liner walls starts to flake or spall it can affect the efficiency and safety of your chimney.
Gaps Between Flue Tiles: Gaps can form between flue tiles and cause improper venting and increased fire risk.
Several external factors can also damage your chimney and require relining or repair:
Chimney Fires, Water, Lightning or Settling: Chimney fires, water damage, lightning strikes or natural settling can damage your chimney lining.
Older Chimneys Without Liners: Many older chimneys were built without liners and needed to be lined for safety and performance.
Worn-out or Deteriorated Liners: Liners can wear out over time and no longer protect your home from hazardous gases and high temperatures.
Proper Sizing for New Appliances: When you install a new heating appliance, you may need to reline or resize your chimney to ensure its correct and efficient operation.
Gaps Between Flue Tiles: Over time, the heat, moisture and chemicals produced during combustion can erode the mortar that seals the flue tiles in your chimney. This erosion creates gaps or voids between the tiles and compromises the flue and its ability to vent hazardous flue gases safely from your home. Harmful gases like creosote, soot, carbon monoxide and corrosive chemicals can escape, and your chimney’s flue is designed to vent them out of your home safely.
Cracked Flue Tiles: Flue tiles can crack from sudden events like a chimney fire, lightning strikes or seismic activity. Poor artistry or natural settling of your home can also cause cracks in the flue walls, which can compromise your chimney’s safety and efficiency.
Flaking Flue Tiles (Spalling): Over the years, exposure to corrosive chemicals and moisture can attack the clay flue tiles in a sound masonry chimney and cause them to flake off or delaminate – a process called spalling. This deterioration further compromises your chimney’s performance and safety.
At GMT Home Services, we stress the importance of regular chimney inspections and maintenance. By finding hidden dangers early, we can keep your home’s heating system safe and efficient.
Homeowners often neglect chimney repair and relining until the damage is visible during an inspection. The NFPA and CSIA recommend replacing or relining flues with cracks, gaps or other damage for safety. At GMT Home Services, we put your safety first and can walk you through the necessary building and fire codes to keep your chimney fully and completely sealed and compliant.
Inspect your chimney liner to see the extent of the damage
Clean the chimney to remove any debris or creosote buildup
Determine the best repair method for your chimney liner. There are several ways to repair chimney interiors, each for different levels of damage.
Consider hiring a professional to do the repair
Heat Shield Restoration System is a repair method for restoring a chimney’s clay flue liner in older chimneys using the Heat Shield system. It addresses gaps, cracks, and spalling to maintain chimney integrity. The Heat Shield system uses HeatShield Cerfractory Flue Sealant to fill voids, repair mortar joints, and create a smoke-tight seal. This system can repair clay tile liners and other types of chimney liners.
Stainless steel chimney liner replacement: the most cost-effective way to repair damaged or deteriorated liners
Cast-in-place liner repair: a durable and long-lasting way to repair damaged liners
Clay liner replacement: the traditional way to repair or replace damaged clay liners
No one chimney liner fits all chimneys. It depends on your chimney and your budget. The main types of chimney liners are clay tile, metal and cast-in-place. Clay liners are good for new construction but are labor-intensive and expensive to reline as they often require breaking sections of the chimney. Metal liners, especially stainless steel, are preferred for their compatibility with all fuel types and durability and often come with a lifetime warranty. Aluminum is a cheaper option but is only compatible with certain gas and heating appliances. Cast-in-place liners made of a cement-like material offer great insulation, chimney structure and creosote buildup reduction. The choice of chimney liner repair system depends on your chimney and your budget.
Chimney liner repair is essential for safety and efficiency. The HeatShield Restoration System restores clay flue liners and addresses gaps and cracks. Other options are stainless steel liner repair system ($2,000-$5,000), cast-in-place liner repair ($1,500-$3,000) and clay liner replacement ($1,000-$2,000). Regular maintenance, including annual inspections and cleanings, will extend the life of your chimney flue liner, with durable options like stainless steel requiring less long-term maintenance.
A stainless steel liner can be a cost-effective solution to replacing a faulty flue line. To install the liner correctly, you need to take precise measurements to ensure the pipe is the right size.
The average lifespan of chimney liner replacement is 10-20 years, but sometimes, it may have to be replaced for 20 years or more.
While there are many DIY options, chimney liners are recommended by experienced chimney professionals and those with the proper training.
