Browse Forums General Discussion 1 Oct 06, 2016 8:13 am I am looking to fully block off a chimney in an Art Deco house in Australia and have found a few ways of doing it but there are forums in the UK which talk about the problems with fully blocking chimneys in homes pre 1950's. They say that fully blocking off the air flow will cause damp issues to arise on the inside walls of the room where the chimney is situated due to materials used in the lining of chimneys. They mention adding a vent of some kind but that seems to be defeating the point of blocking it off as draft and noise will still get through. Before I go ahead I would like to know if this problem will also occur in Australia? Has anyone got any experience with this issue? If so what are the ways of avoiding this damp issue whilst still being able to block the chimney off? Your help would be very much appreciated. Re: Damp issues blocking a chimney in Australia 2Oct 20, 2016 7:01 pm Not much interest here Renoman. I don't know anything about the damp issue, but might be able to offer some advice, coming from a different angle. My house is a 2 storey Victorian, 13ft ceilings, solid brick walls and cold, cold, cold! I wanted to do something about the cold draft coming from the bottom of the walls, so I sealed all the way around the walls and that fixed the draft issue. Trouble was that the open fireplace wouldn't draw as not enough air could get into the room. I fixed that by putting in a floor vent and now no smoking chimney. You don't say why you are blocking the chimney - draft and noise? If draft is the issue then sealing the room so little air can get in will stop air going up the chimney.

I am looking to block off the chimney for both draft and noise actually as we live on a main road. That is a good idea to seal the whole room so not much draft will travel up the chimney. I would have thought more people would be blocking off chimneys in older houses here too. Maybe the damp issue isn't a problem in Australia.
