I have a few question regarding chimney liner

1) I will need 2 liner about 20 and 30 foot long. I have gotten estimates range from $1500-$5000. That is obviously a wide-ranging margin. What is a average price for the liners installed beside insulation

2) Half the contractors/shops I spoke with said insulation around the liner is indispensable, while the other half said it wasn't compulsory. Is the insualation necessary?
--we own an outside brick chimney. The flue 'is cracked in a few areas', this is why we necessitate a new liner

3) Another contractor I spoke to said it may be critical to take out the hoary clay tiles before putting the contemporary liner in. would this be essential if I'm getting a new stainless steel liner put within? considering nobody else mentioned removing the current tiles.

Any advice to gather me a little money would be greatly appreciated

Thanks

First, you don't inevitability to insulate the liners. Second, you don't want to take out the clay tiles. The liner go inside it. Third, that price range sounds without doubt ridiculous. A air price would be around $1000. Depending on the situation, you can also use one liner instead of two.
