Most homeowners do not think about their chimney liner until someone tells them it needs to be replaced. Here is what it is actually doing while you are not paying attention. The liner contains combustion gases (including carbon monoxide) and channels them up and out of your home. It protects the masonry from the acidic, corrosive byproducts of every fire you have ever burned. And it maintains the draft that pulls smoke out instead of into your living room. When the liner cracks or collapses, those three jobs stop happening. Carbon monoxide is colorless and odorless, so you do not get a warning. Our new guide walks through how to spot liner failure early.
