Advantages of a masonry chimney liner
Adding a liner to a masonry chimney will help keep toxic gases out of the house and also prevent the heat and fire from the fireplace from igniting the creosote buildups in the masonry chimney. A chimney fire can spread to the roof, attic beams and joists and deal a great amount of damage. It’s best if you take your precautions and add a liner to your chimney.
