Do I need to cap the flue if boarding up a fireplace?

Anonymous user 15/03/2024 - 2.44 PM

We are about to board up a fireplace (where there was a small gas fire) and have the room skimmed on the ground floor. The whole house has a suspended wooden floor and air ventilation bricks in all external walls. Do we need to have the flue capped off or, if not, a small vent put in the wall to avoid condensation/damp. Or will the sub-floor ventilation be sufficient to prevent damp if the flue is not capped?

Are you a tradesperson and able to answer this question?

all unused fires should be capped at roof level and vented at room level to prevent water ingress from the chimney stack & a build up of condensation in the flue. good luck alex
