Chimney Liners

A Chimney Liner May Be The Answer
Chimney relining is usually the most practical and affordable way to repair a deteriorated or damaged chimney.  The most common cause of chimney damage in a fireplace flue is a chimney fire.  The most common cause of chimney deterioration in a heating system flue is the acidic environment created by burning fossil fuels. Chimneys can also be damaged by a number of other things such as settling, hurricanes and lightning.

Lining may also be needed for older chimneys that were built before tile liners were required as part of chimney construction.  This is what is referred to as an unlined chimney.  To conform to current building codes a liner must be installed whenever a new heating appliance or woodstove is to be installed into an unlined chimney.

Recap of Reasons to Reline:
  • Repair damage to the chimney caused by a chimney fire or lightning strike, etc.
  • Restore old chimneys that were originally constructed without chimney tile liners.
  • Replace worn, deteriorated tile liners that may be allowing carbon monoxide, smoke, creosote or condensation to seep through the chimney walls.
  • Downsize the chimney flue for a new appliance; for example when converting from oil to gas heat.
  • Prevent excessive creosote buildup (and risk of a chimney fire) when venting a woodstove through an existing fireplace flue.


Types of Liners:

  • Cast-in-Place -- This is the poured concrete method that is most appropriate for older, unlined chimneys. We use the Golden Flue product and lining method. It is suitable for almost any size chimney: from a large antique chimney with several fireplaces venting through it to one with a single heating flue.  This is also the best method for restoring a chimney flue damaged by a chimney fire.

  • Stainless Steel – This method of relining involves installing a round or oval stainless steel liner in the chimney. The liners are usually flexible which allows them to be installed through offsets.  Stainless Steel liners are used mainly for woodstoves and heating system installations. Chimney Corners offers UL Listed stainless steel lining systems that come with a manufacturer’s Lifetime Warranty.

  • Aluminum – This material is installed the same way as stainless steel, but a liner made of aluminum is far less sturdy and resistant to corrosion. For these reasons aluminum liners can only be used to vent certain types of gas appliances. Note: Gas logs intended for installation in wood burning fireplaces may not be vented with aluminum liners. We do not recommend, nor install, aluminum liners.

  • Flue Tiles – Used mainly in new construction, this method of relining may be suitable for short, straight chimneys. If you have any doubts about your chimney, give us a call.
