A flue liner acts as a channel that keeps a chimney safe from creosote formation and from other damages. If your chimney is made of brick, having a flue liner will keep the mortar on the bricks from being degraded thereby lengthening its life.

For the average homeowner, installing a flue liner will cost about $2500.

For more expensive liner materials, the cost may go up to $7000. Homeowners who need to install the liner themselves will need to buy DIY materials that can cost up to $625.

With a good liner, the chimney is protected from decay.

Factors that Affect Cost

Liners run the length of the chimney to keep it safe.  Therefore, the cost of flue liner installation will be affected by the length of your chimney.

This will obviously dictate the length of the flue, which is one of the main factors influencing cost.

Some chimneys already have flue liners installed while others need it installed. If you have a flue liner that you suspect is in a poor condition, you might need to hire an expert to have them inspect it and decide what needs to be done.

Repairing the flue will be cost-effective compared to installing a new flue.

Other factors that determine cost include the diameter of the flue, number of units connected to your flue, the type and material of the liner, and the presence or absence of insulation.

Besides the cost of material, you will need to factor in labor.

 

Types of Liners

Liners are classified based on the material they are made of. Stainless steel is cheap, costing about $65 per foot of the chimney. Most average homeowners prefer to use stainless steel thanks to the fact that it is cheap and durable too.

Clay, also referred to as Terra-Cotta is the cheapest with a foot costing $10. Aluminum costs $12 per foot while cast-in-place and Thermocrete cost $250 and $200 respectively.

Homeowners can choose based on their budget or how much they are willing to invest on their houses.

Besides the cost of the various materials, homeowners need to consider the longevity and advantages of each. The cost of installing the various materials is different, and so are the installation labor costs.

 

Labor Costs

You might have to pay between $1600 and $5000 to have these liners installed. To some people, this is a hefty price for a flue liner that will never be seen.

However, you need to consider that liners preserve your chimney and enhance the efficiency of your home’s heating unit.

With a good liner, your home is protected from a fire which might result from the formation of creosote. Some liners will reinforce structures that are nearly falling.

The whole installation, from the materials to the labor, will cost you between $1000 and $7000.

Maintain Your Chimney

Request to have your chimney liners replaced or have new ones installed today. Once the liners have been installed, you need to keep them maintained to enhance their productive life.

If you do not want to keep replacing liners after every few months, have a professional look at them routinely.
