The hardest part about relining your chimney is fitting the chimney liner. You need to properly size the liner in order for the chimney to draft properly.

Chimney liner insulation is extremely important and actually helps to reduce creosote build up by keeping the chimney liner warmer. Chimney liner kits vary in price based on the diameter and length of the liner, but a basic, UL listed 6″ diameter 20′ long chimney liner kit, complete with connector pipe, tee end cap, and top kit can be anywhere from $400 – $600.
