Chimney Liner Cost & Installation

Installing a chimney liner can alleviate a lot of problems in old houses where the brickwork of the chimneys need maintenance, they can also be installed in new houses and there are a choice of three options.

Chimney liners are often used when replacing old fireplaces and boilers. Most old house owners relish having a real fire burning in the hearth in the winter.

But to be able to do this year after year they have to carry out a routine inspection of the chimney maintenance. The National Fire Protection Association requires that all chimneys burning solid fuel, wood, coal or pellets should be inspected annually and cleaned whenever they need it.

These inspections help to identify defects that might lead to deadly gases leaking into the house and stop chimney fires caused by the build-up of creosote, which is the natural by-product of burning wood.

Chimney liners are ideal for masonry chimneys that were not built right in the first place and do not have a flue liner, which is a material that provides a smooth, seamless surface as well as insulation.

Lineless chimneys are very common in old houses and age and use can open up cracks in the tiles. If you have your house inspected and it has resulted in a recommendation that your chimney needs re-lining there are three options

  • Reconstruct clay tile flues with new clay tile liners
  • Reinforce the chimney and create new flues with poured-cement liners.
  • Reline existing flues with metal liners.

Clay is one of the most common types and the most popular as clay tiles are inexpensive and very effective when used for open fireplace chimneys. These chimney lines are also very durable and most of them last at least 80 years. Clay has two disadvantages. Clay chimney liners are ceramic and if there is a chimney fire they will crack or split apart.

Used with gas fireplaces they won't be able to contain combustion by-products of the fire.

Concrete is poured into the interior of the chimney to make heat-resistant cement chimney liners. It forms an insulated pathway for gasses to be vented outside. The disadvantage of cement liners is they are permanent and cannot be removed.

Metal Liners are usually made from stainless steel or aluminium. Stainless Steel can be used for all surfaces but aluminium can only be  used for certain gas fires.

There are no regulations prohibiting the instillation of chimney liners as a DIY job, but they do have to be installed in accordance with the Building Regulations Part J, and you should notify your local authority or council before installing a chimney liner.

In America you can buy stainless steel chimney liner kits which are made from the strongest grade 316ti chimney liner.

The low stainless steel liner cost and extremely high quality make them good for re-lining existing chimneys or for any new construction.  One of the best sites to buy the kits is Fireplace and Chimney Supply

The kits range from $299.94 to $485.21.

A chimney liner for a gas furnace or gas boiler ranges from $300 and $700 and for coal or wood-burning fires $1,800.

If you can install the chimney liner yourself if will save a lot of money as the cost of labour is usually double the liner cost.

I found this page by googling "how long do chimney liners last?" It is answered for clay liners, but NOT for metal liners. Please include it, as it is a very common type of liner people like me are looking for.
