Chimney Liner Repair

Prompt Chimney Liner Repair is Essential for Protecting your Home and Family from Fire

By Mark J. Donovan

A chimney flue lining plays an important safety role in protecting the home from fire and thus chimney liner repair should never be put off if a chimney inspection reveals a cracked or broken chimney liner. If you have an old home with an unlined chimney it is extremely wise to have a retrofit chimney liner installed if the chimney is at all being used. Unlined chimneys commonly lead to fires in the home, particularly if the chimney is an old masonry fireplace that has deteriorating mortar and masonry.

A chimney liner, also known as a chimney flue, is made out of clay, ceramic or metal pipe that runs down the center of a chimney.

The chimney liner’s purpose is to direct the flow of combusted fuel products up and out of the home and to protect the chimney walls and surrounding home structure from heat, fire and corrosion. Over time, or from intense heat or cold, a chimney liner can become damaged or cracked.

There are a number of chimney liner repair options you can consider in the invent it is determined that your chimney liner is damaged in some way. However it is important to note that when repairing a chimney liner, a chimney flue liner needs to be properly sized to maximize the efficiency for your particular heating appliance, be it a wood stove, oil or gas burning furnace, etc. Check with a chimney professional before deciding upon the right chimney liner repair course of action.

Chimney Liner Repair Options

Metal chimney liners, normally constructed out of either stainless steel or aluminum, are probably the most commonly used in chimney liner repair.

Metal chimney liners, when properly installed, are extremely safe and rugged. Stainless steel chimney liners can be used for gas, oil, or wood burning stoves and furnaces. The less expensive aluminum chimney liner is sometimes used in certain gas stove applications.

Cast-in place chimney liners are commonly used to repair masonry chimney flues. Cast-in place chimney liners involve inserting a cylindrical bladder into the damaged chimney flue and then pouring a lightweight, castable, cement like product down the existing chimney flue.

The bladder is then removed to create a smooth and seamless chimney liner. Two of the particularly good benefits with this type of chimney liner repair are (1) that this type of chimney liner can be used with all types of fuels and (2) it improves the structural integrity of the masonry fireplace.
