Recently moved into an older house that has had a chimney breast closed up. It’s has an air vent on the downstairs living room and also has one in bedroom directly above the living room. I was wondering if it would be possible to dob and dab over the air vent so there would be a small amount of room for ventilation behind the plasterboard, or would this cause damp? Just don’t want the vents in the rooms
Thanks
