Capping chimney top
Questions for people that don't use their fireplace.
Did you cap your chimney off at the top, or close it at the bottom with a fireplace balloon / stuffed something in there, or do you leave it open?
If you capped it off at top Im aware it needs ventilation from the bottom (either leaving fireplace open or closing off but installing a vent), however does it still need some ventilation at the cap at the top? I'm considering capping it off.
