New Chimney?

New Chimney?

PostBy: Devil505 On: Thu Jul 03, 2008 7:13 am

I'm considering replacing my existing block chimney & looking for some input. My existing chimney was built 26 years ago by a new mason & passed inspection when built. The mason did not remove the shingles on the side of the house but simply erected the chimney butting up against these shingle. The original thimble was a double wall metal one that rotted out years ago & which I have been jury-rigging with plain old stove pipe shoved through the wall & centered in the flue for many years. I know...I know....but I replace this homemade thimble every year & while I wouldn't want to have it inspected, it really is pretty safe.
(there was a metal clean out door on the outside that rotted out years ago & which I sealed with a few cinder blocks (as seen in middle pic)

I am getting 3 or 4 estimates on a few things:
1. Fixing the thimble professionally
2. Tearing down the chimney & have a new one built

The first mason came by yesterday & I was impressed with his apparent honesty. He told me that it may be safe the way I was doing it, but that he couldn't touch it (as far as putting in a new, masonry thimble) as he could lose is license if there was a problem with the rest of the existing chimney & is going to get back to me with a price on replacing the whole thing.



My questions:

1. Should I just try to find someone to replace the thimble with a masonry one & call it a day?
2. Should I replace the whole thing?
3. If I do replace the chimney, any ideas/recommendations on tops to keep birds from nesting in the summer? (metal caps quickly fail due to acidic coal gases, I guess)

It would be a shame to tear down all of that block. Can you get someone to line it with terracotta? I'm not sure if it can be done because the liners are two foot each.

There is a clay liner in the block already, (I think) extending a few feet above the block at the top. (funny but I can see it coming out of the top of the chimney but when I look through the thimble into the base, it appears to be just block inside??)

A lot of guys won't take the time to cut the clay liner to go down to the base of the chimney. They put the thimble in and start the liner from the top of the thimble. That's probably why you can't see it. If it passed inspection the liner should be in the whole chimney above the thimble.

If it's a clay lined chimney why do you want to replace it? I'm in the process of putting up a masonry chimney that's about the size of yours. I got prices between 3,000 - 3,800 to have it done. The material cost me about 600, my labor and a case of beer for my helper.

It's early and I don't think I've had enough coffee yet but I think you're saying the thimble needs to be replaced. Have someone put in a terracotta thimble. They last forever and are only around 30 plus the cost of installation. That beats replacing the entire chimney.

I bought a stainless steel chimney cap. If stainless will last as a chimney it should last even longer as a cap (I hope)

Where did you get it? (Home Depot & Lowes just have the cheap ones)

I bought it hear from Freddy. He had a couple of them. If he doesn't have any more maybe he can tell you where to get them.

I just checked Lowe's online. They carry a stainless steel cap for 50.00. If it's not at your local store you can order it online.

Find another HONEST mason and replace the thimble properly. If it's not coming apart, your chimney should be fine.

LOL...Someone less trusting than me!?!?....I love it!
I will certainly not do anything until I have had a few brick masons look at it & give me estimates. I told this guy yesterday that I would be getting a few estimates & he said that was the only smart thing to do, so that kinda won me over. (Why would a guy try to con me when he knows other brick masons will be looking it over & giving bids?...........I guess it takes all kinds)
Anyway, I'll find out b4 I do anything

Hi Richard,, other than the thimble what issues does the chimney have?? If I remember, you don't have any draft problems.

I'd follow the suggestion above and put in a terracotta thimble,, just mortar it in,, and replace the cleanout door,, they are cheap.. Just paint it with good enamel or Rust-Oleum paint [a very good enamel] before installing it... It will last a long time..

With only a few repairs to do,, I'd save the $$ and spend it on a coal bin or another load of coal before the prices go higher..

Really none Greg & the draft is fine. The mason yesterday was making a big deal about the original mason not removing the shingles & butting the chimney firmly to the plywood side of the house. He said moisture could get between the blocks & the house & may rot....Sounded reasonable to me??? That plus the original mason using a metal thimble had the new mason worried about his work. (As you know, I'm not a brick mason by trade.......I am a professional "Conspiracist" ) :lol:

I think your original mason knew you were a fed. He was actually a KGB double agent trying to get coal burners like yourself to spend more money. :D

Here's my opinion on your chimney. The fact that the wooden shingles were not removed doesn't matter. The chimney block with a clay liner meets the code requirement for distance from a combustionable wall. I would determine if there is a clay liner at the thimble height and below. If not while you are adding an new clay thimble also add a section of clay tile at and below the thimble. It can be done by a mason with a diamond blade circular saw. I just had it done. One side of the chimney block was cut out giving access. A clay tile was trimmed to fit and mortared in place. The block was then replaced with 4" wide hallow core blocks. I would also make your clean out door functional. Replace with a cast iron or composite cement one.

Thanks for the help guys......I think I will just get the thimble & the clean out door replaced, as you recommend. (I thought the brick mason that said I should replace the whole chimney looked a little like GW Bush!! :eek2: )
