Chimney Relining: The reasons and the options

The chimney lining serves the important function of keeping heat inside the chimney and away from the combustible areas surrounding it. The majority of masonry chimneys have clay-based liners which inevitably crack and crumble over time. Other traditionally-popular liner materials are aluminum and stainless steel. Although aluminum and stainless steel liners can be long-lasting, when sulfur and water combine inside of the chimney, the mixture can corrode these metal liners leaving the framing and walls of your home in danger of high heats. When having your chimney resurfaced, we will help you decide on the best material for your needs and location.

In addition to confining the high heat of a fire, the chimney lining also serves the purpose of keeping your home protected from carbon monoxide, water, soot, smoke and other fire by-products. If your chimney lining has cracks or holes, these elements have a free entryway into the air you and your family breathe. Exposure to these harmful elements can cause allergies, asthma and other respiratory problems and can even be life-threatening. According to the Chimney Safety Institute of America, as many as four thousand Americans die annually from carbon monoxide poisoning. In addition to these deaths, countless other individuals have suffered permanent brain and organ damage or other ailments as a result of exposure to carbon monoxide. For this reason, it is imperative that you have your chimney lining inspected and repaired or installed (if needed) by a professional.
