In our front room we have large patio doors and windows but at one side is a cavity airbrick. So that side of wall is prone to condensation, mould, paint bubbling etc.
So we plugged the chimney as it was heat loss, sound, smell of burning from neighbours log burner forced in when we run the kitchen extractor fan. Since then the condensation has been worse as the chimney provided natural ventilation.
My question is can I block the vent. The house has cavity wall insulation. Some vents have been blocked up. Siliconed over the front due to cavity wall insulation I'm guessing.
There are vents about a metre up from ground level then one right up near roof level. The one I want to block is one of the only cavity vents not blocked up and the one directly above it at roof level is not blocked either. Due to the vent being open that wall is obviously the coldest part of the front room so instead of the windows getting condensation that wall takes the brunt of it. I know condensation is an issue. We do have a dehumidifier but don't run it 24/7. Do I unblock the chimney to allow that natural ventilation again and just put up with the negatives or can I block the vent up?
