Chimney Liner Replacement

A proper functioning chimney liner is critical to the performance and ultimately the safety of all occupants in the home or business. There are currently two types of replacement chimney liners that your Always Affordable Chimney technician can install for you. The stainless steel chimney liner has been the standard that has been used to replace the terracotta clay chimney liners that are found in most homes. In recent years, a stronger liner has been developed. This is the FuranFlex, made up of composite materials. There are many advantages that the FuranFlex chimney liner has over the stainless steel liner but both are excellent choices when a liner needs to be replaced. Most importantly, for safety reasons, it is critical that your chimney be inspected annually. Call us for our Free Chimney Inspection Service.

The purpose of a chimney liner is to keep the heat of flue gases inside the chimney so the chimney can’t overheat nearby combustible material (such as the framing and walls of your house) and possibly cause a fire. The liner also keeps carbon monoxide, moisture, smoke, creosote, and other products of combustion from seeping through the bricks and mortar of your chimney and leaking into your home.

Fitting a chimney with a properly sized liner is the best line of defense against future problems. This ensures good draft by preventing flue gases from expanding and cooling.

The liners we provide are:
