An often overlooked part of your chimney’s anatomy is the chimney liner. We tend to think of the chimney itself as a sturdy, indestructible structure, but it takes wear and tear like other appliances. The chimney liner plays a big part of keeping your interior safe, and your chimney strong. As hard as it may be to believe, some homes used to be built without chimney liners. Some of the liners that were installed don’t meet the standards of today. If the chimney liner protects the chimney, what protects the chimney liner? At SirVent Chimney and Venting Service, we can answer the question, and follow it with some action.

First, it’s important to understand exactly what it is that the chimney liner does. The chimney liner has three main purposes:

  • protect the brick and mortar of your chimney from the corrosive effects of the chemicals released during the combustion process
  • to keep flammable items that are close to your fireplace safe from the possibility of getting too hot and spontaneously combusting
  • make your fire burn more efficiently by making your chimney the correct size for easy transfer of smoke out and allowing enough draft in for your fire to burn properly. An added benefit of this is that less creosote will build up.

Does Your Chimney Need Relining?

It is very important to make sure that your liner is in great working condition. This is hard for a homeowner to determine on their own, however. It requires special tools and a certain level of know-how to see whether the chimney liner is intact and fits correctly.
