Hi, I have a rental property which still has all 4 chimneys on 2 stacks. The chimneys are topped with round crown pots which I don't want to remove. 2 of the fireplaces are still used from time to time, the main problem is one that is now sealed up, apart from 2 small vents in the dining room is getting damp on the internal breast. I'd like to keep the chimneys open for ventilation, is there a way of capping a round crown chimney pot to stop rain but to still allow ventilation? I've seen many devices but unsure any would fit a crown pot?
Thanks, Mark
