Chimney liner options and costs?

[michaelthomas]

I have an exterior masonry chimney 2 stories and a basement. 8x8 clay lined chimney. How long do these types of liners last? Are there things to avoid with the clay liners to avoid damaging them? If it needed to be replaced what are the replacement options and approximate cost of each. Thank you for your wealth of knowledge.

clay liners are the longest lasting most durable acid resistant liner you can have; the thing that causes them to crack and deteriorate is having a chimney fire, more importantly a very fast igniting and buring one, this is because often the clay liner is not given enough room in the chimney to expand and this coupled with a fast, hot chimney fire can cause them to crack.
