Sweaty fireplace opening on super hot days. Condensation on insert, how screwed are we?
Hey,
So I’m not sure if anyone can give me some ideas. But we have an older house (1960) and when we bought it the fireplace was non usable. I didn’t hear much aside from that. We noticed a draft and the opening was always closed, so we added an insert (first a wooden one) and then a basic metal insert. Seems totally fine most of the year, but on VERY hot days the fireplace opening will get sweaty right around where the insert is. It also is stinky like mildew or something.
We’ve had this house for 3 years. And there’s constantly crap happening. Having a chimney tec sweep it out and inspect it to see if they can figure out the issue. I’m hoping it’s as simple as installing a top seal damper. I don’t believe we currently have a damper. We eventually will install a gas insert.
Just really hoping someone can give me some hope that it’s not going to be a giant repair we have to tackle again.
I’ve worked masonry before in the summers (teacher) and the points look cdecent, nothing crazy.
Thoughts?
