Condensation above unvented flue
Michelle posted on the 22/01/2017 11:35:49 AM
Was wondering if anyone had dealt with this problem? I noticed condensation on our back room ceiling and a cracked has started to form. Checked with the neighbours upstairs and nothing was leaking but they did let me know there was a fireplace directly above. Their fireplace is in working order. I'm now guessing this condensation is from the unvented flue, but there was no damp detected in the home report (bought the property last month).
Does anyone have any advice or names of damp specialists I could contact?

The chimney cannot be unvented if it is in working order . It will rise out onto the roof and vent there for combustion purposes . If you had a fire installed into the fireplace and had it bricked up it should have had a vent installed to it also

Thanks gas man. It looks like the previous owners have bricked it up at some point and not installed a vent. I'm booking a plasterer and a damp specialist. No idea what work will be involved or the costs....
