The only concern that I'm aware of with old chineys is flue gases seeping through joints into the home if you have a chimney on the inside of the house.


Unless there is a huge hole where the gasses are drafting into the house rather than out the top this can never happen. No gasses come out the barometric damper, because the chimney sucks it doesn't blow. A crack or missing brick will cut the draft some, but the only way CO will enter the house through an unlined chimney is if there is no draft or the top of the chimney is plugged, and in both of those cases you have a huge problem that needs immediate attention that a liner wouldn't have solved. The safety concern with an unlined chimney is it can't handle a chimney fire, your house will burn to the ground before you get it put out if it's sucking air through the cracks in the mortar.

If you absolutely must line the chimney, I would think the cast in place liners are the best. Some have an insulating filler and the chimney flue itself gets a coating of ceramic. I can't see anything better than that.

My son-in-law was quoted $1500.00, but that was by a mason who's a friend.
Thanks devil, still seem high for our price range. Any ideas on what a SS chimney would cost?

That makes sense, never thought of it providing a draft for a chimney fire. Considering that I wonder why they are specifying it for for gas and oil fired units? I know the one previous poster mentioned it deteriorates the mortar but I would think the major concern here would be the providing a draft for a chimney fire and mandating it in chimney used for wood would take precedence over gas and oil.

I don't, but I don't think it would be that much cheaper than a masonry one. (Plus you'll have to replace the steel chimney in a few years & the masonry one will last forever)

According to this site

for coal piping the Metal-Fab comes with a 10 warranty and the Simpson comes with a lifetime warranty. So ten years for a chimney should achievable don't you think?

I'm not a big truster of company warranties (which most of the time is "We'll pay if you can find us!") & my attitude is why take the chance? You know a masonry chimney will last forever & you know a steel chimney has a very finite lifespan & is not cheap by any means! Go with masonry & avoid any future worries.

I just finished putting up a masonary chimney, 30' high 8x8 single flue, below grade was block, above grade brick, with the thimble, SS cap, and cleanout door it was $2,400.00. When I first started pricing, I was quoted $1,400.00 just for materials for a SS chimney, add in the labor and you very close to a masonary one which will last forever.

If you forgo the brick & (just go block all the way if it's not all that visible) it would be even closer to a steel chimney in price.

I might even be cheaper, it was a lot more time consuming to lay brick than to set the chimney blocks. Also the blocks were only $5.50/each, you'd need 24 brick to = 1 block which would be around $12.00. Mine is visible, so I chose to go with brick, another option is to box in the block and side it later on.

Thanks guys, I would love to build a nice masonry chimney but I'm really not sure if where we are putting the stove is going to be it's permanent place or not?

Then I suggest............You decide! :lol: :devil:
(& you can then change your nickname to Adamiswarm, plus you can't easily move even SS chimneys as easily as you rearrange a throw-rug) :D

If it is an outside chimney with a straight shot up The Metalbestos SS is easy to put up. You can sell the pipe on craigslist for about 75% of retail after 2 years unless oil drops to $2/gal again. Check craigslist in Providence RI for ding and dent 36 ft of 8" for $1000
