Ignored chimneys without liners, or an old, worn-out liner can yield serious damage. The build-up of debris can cause fires inside your chimney, which will not be limited solely to the chimney. Cracks in the internal portion of the chimney can result in harmful toxinogens to be released into your home, amongst other issues.
Chimney liners provide a smooth, seamless surface inside the chimney to reduce buildup or creosote and other fireplace byproducts while providing insulation to the flue. This is the safest and most cost effective preventative measure that you can implement to avoid attic fires, the release of toxins, and the internal destruction of your chimney.
