Chimney Liners

A Chimney Liner plays an important part in the chimney, its purpose is to convey the materials of combustion outside of the living area of your home. NFPA recommends an annual inspection of your chimney and upon installing a new appliance this liner should be inspected for flaws and defects that could leak Carbon Monoxide into the living area or cause a house fire should a chimney fire occur. Terra cotta liners are the most common liners in masonry chimneys, these liners do hold up well with regular sweeping but can break down over time and  a new efficient oil or gas furnace will speed up the deterioration of the flue tiles and mortar joints.  If there is a problem with your flue tiles or mortar joints, there are options other than rebuilding the entire chimney. A stainless steel liner can usually be installed bringing your chimney up to modern code and giving your old chimney new life.  In order for a liner system to be UL listed for solid fuel burning appliances such as coal or wood applications the liner MUST be insulated to meet UL 1777 requirements.

Weller’s uses what we feel is two of the best liners on the market their design makes them superior in all aspects of strength and metal alloys and carries a transferable Forever Warranty on materials with annual maintenance of that liner.

Below are some pictures of  liners that failed due to improper installation and substandard materials used by other Companies.

The pictures below show typical deterioration of flue tiles. The middle picture also has misaligned flues and missing mortar joints, since the flue can no longer contain the materials of combustion the flue is no longer doing its job and the chimney should be relined. The two pictures to the right show a typical chimney with leaking or missing flue tiles, the white flakey substance on the exterior is called efflorescence. This is very common with the installation of a new efficient oil burner and a sure sign that the chimney needs a liner, if left go too long it will ruin the masonry and lead to very costly repairs.
