 Chimney Relining, Repair & Cleaning Your chimney probably appears to be in fine condition on the outside. But that can be the problem. Many chimneys that look fine on the outside are seriously deteriorated on the inside. The acidic nature of the by-products from the combustion process can deteriorate liners from the inside out. This can lead to a serious fire hazard, a dangerous flue blockage or even result in carbon monoxide poisoning.  Whether gas, oil or wood is used to heat your home, every chimney must have an approved liner that is in good condition. Fortunately, problems of a deteriorating chimney flue can be corrected without comletely tearing down and rebuilding your chimney.If natural or liquid propane gas is used to heat your home, an aluminum chimney liner might be your best choice. These liners can be made of rigid or flexible materials, depending on details of the application and the configuration of the chimney. Properly sized, more than one appliance, a furnace and a hot water heater for example, can be vented into the same pipe. Aluminum is used only to vent gas appliances. If fuel oil or wood is used to heat your home, a liner made of stainless steel with special alloys has been developed to resist corrosive acids. Properly sized, more than one oil appliance can be common vented. Common venting with wood appliances is not permitted.  In our opinion, a cast-in-place liner such as Ahrens Chimney Technique is the best method for relining and restoring structural integrity to a masonry chimney, regardless of the fuel that is being burned.All masonry chimneys, regardless of age, could have defects that are not visible. Potentially dangerous situations such as cracked or broken flue tiles, improper clearances to combustibles, or many other problems could go undetected by the untrained eye.
