Ok so an update, I CCTV’d the inside of the stove pipe. I taped my phone to my brush set and slowly went up and down the chimney.

The video didn’t show any issues. HOWEVER, I think I have a blockage in the rain cap. Would that be the source of my problems?
There still should be no way for smoke or creosote to come out of the joints. I cant tell you exactly what is wrong but what ever it is could potentially be very dangerous.
 
Gotta take it off and clean it. No other way around that.
 
The new chimney to replace your worn out one will come with a shiny new cap

Thanks for the info I’ll head up there tomorrow and clean the crap out of it and retest.

Would love a shiny new one, but was quoted $3k yesterday for one. If that’s the case it will have to wait until next year.

I understand limited finances. But if those seams are leaking creosote the insulation could easily be saturated with it causing a serious fire hazard. And if smoke leaks out when its plugged air surely is leaking in normally making the creosote buildup much worse. I would absolutly not use a chimney in my house if it leaked like that. There is just way to much at risk.

What is included in the quote? If you are able to get on the roof to clean, safely, then you may be able to replace the pipe yourself, if the ceiling support box doesn't need replacement and it will work with modern H&C chimney. You would need to call their tech support to determine this.
 
So an update, got up on the roof this morning before work to inspect and clean the rain cap. The cap was definitely the source of all my problems!
 
Here is a picture of the issue

still I would not think that it would leak out seams, back draft out stove yes. Still the issue of the creosote formation. The fact that it was dripping and running down is a cause of major concern. Major problem waiting to happen. that has to be the worst I have ever seen
 
I haven’t been up there to clean it in the 4 years I have lived here, so who knows when the last time it was cleaned.

I sweep it regularly but until now I haven’t thaught of that needing a separate clean also.

I did speak to a professional who said that this explains everything.

The professional was wrong. Even with a plugged cap there should absolutly be no smoke or creosote leakage from the joints.
 
Then possibly the upstairs is acting like the top of the chimney, bypassing the blockage? Cant believe it would draft enough to run the stove though. Sounds crazy.

Several years back we had a screen plug up like that after burning some wet maple, but there were no creosote leaks. Instead the flue just stopped drafting and the stove spilled smoke badly when the door was opened.

Exactly what was listed on the professional's quote for replacement? Did it include replacing the ceiling support? If so, $3k is not out of line.
 
OK, then it is not unusually high.
