It costs a hell of a lot more than a terracotta tile liner, and the metal liner, even the very best stainless steel could corrode through in 10+ years..

Or you could put in a terracotta clay liner, and leave it for the next 100+ years... Your choice.

I just want to make the best choice, are round and square clay tile the same price?, Round seems to be better do they both fit in the same size block? If you use round they interlock and there is no need for mortar inbetween them, from what I understand.

At my mason's supply companies, the round tiles were more than double the cost of the square or rectangular ones.. in your area this may be different.

I just finished pulling down my brick chimney today. The last 6 feet collapsed as I pulled the flue tile out. Now to jackhammer out the old footer and pour a new one. Then the build can start.

use type s mortar for the masonry available at any supply house bagged, and fire clay for the flue joints, just ask the supply house for the flue tile mortar, they'll supply u with the right stuff.

Carnage....congrats on the un-do. That's a lot of work behind you. Now, forwrward you go!

When you buy parts for a new mason chimney, don't look at each price. A couple of things will scare you. The fireclay and the lead flashing are stupid expensive! Just look at the total bill & it's not so bad.

I thought there was special stuff when doing a coal chimmney, do to the corrsive gases.

Lead flashing?
Who uses lead flashing anymore.

What would you use besides lead that lasts as long? Maybe copper if you don't mind green streaks .

Most people around me use the brown or white aluminum flashing. I have used the vinyl flashing but not for a chimney, may work ok.
Heck I did not know you could still buy lead flashing. Tore of hundreds of pounds of lead flashing when I was a roofer. Always replaced it with aluminum except for flat roofs where the lead was replaced with rubber.

Lead flashing is far superior to aluminum or copper flashing especially in masonry. It is used extensively still in europe and has shown it's superiority over time.

Lead is perfectly safe,, just don't rip off a corner and chew on it..

It is very expensive now.. with the EPA and all the hysteria over lead poisoning, it is difficult to get in the states.. You can find it in Canada.
