    White duck tape it is. Cover off seal with duck tape and cover back on.

    Is that vent on a chimney, where the open fire has been taken out and bricked up/sealed?

    Winter requires working vents more than any other time of year to prevent condensation, damp and mould .

    I agree, but it requires proper care in limiting moisture generation and its extraction. Vents will help, but they can make a house/room awfully cold and waste heating, not the best way of defeating moisture. Many older homes will have been built with vents installed for open fires, which were removed decades ago.

    How do you limit moisture generation? Stop breathing ?

    Just received this from a friend.
    Vent was kept shut by tenants and boiler room filled with duvets and old clothes.

    I think thats an adjustable vent - the face plate moves sideways to open or cover.

    Yes, it is.
    The tenants closed it and filled the room with clothes.
    Inevitable condensation

    I it's on the top corner of the house no chimney. I am going to open lock pvc windows in room not used. I will use extracted fan in kitchen. I will check for condensation every few days and first sign of any the window will be opened in that room.

    No, you make sure there is through ventilation and minimise moisture generation within the house. Extractors in bathroom, extracting cooker hoods, a complete ban drying of clothes in the house and good insulation.

    What additional answer would you expect?

    I have no condensation in my home, no mold, and only one vent like the OP's which is in a disused sealed up fire breast. There are two of us, plus a dog in a three bed semi and we do all breath normally.

    You simply repeated your earlier comment.

    Not exactly, I added to it. Your suggestion of needing lots of ventilation is wasteful of heating energy, a proper planned ventilation system, combined with insulation, works much much and is much fuel efficient, than any random ventilation system in the hope of curing condensation and mold.
