Typical cost: $2,000-$5,000 installed
Cast Iron / Clay Tile Liner

Side-by-Side Summary
Quick reference if you only have a minute:

For any reline or fuel conversion, stainless is the modern standard. Clay tile is only appropriate for original-construction masonry chimneys still in sound condition.
