    I’ve just bought a 300+ year old stone house in Northern France.
    In one room there’s a sealed up fireplace (not very deep).
    The chimney has been capped and there’s no ventilation as they installed a sold cast iron block - I’ll attach pictures.
    From the new plaster down it is very damp with the metal edging on the walls rusty.
    I opened up the metal seal - the cavity was filled with dead bees - millions of them!
    I need advice!
    Should there be a ventilation plate put in or do I need to do something else as I need to sort this damp issue out.
    Thanks in advance for any help

    You need a through air flow, a cowl rather than capped off. Could well be other issues, whats on the other side of the chimney breast, is it watertight, condition of pointing/render etc.

    Thanks for replying so quickly.
    This is the wall that’s behind the chimney. EC2FB3D7-8E9B-4F87-B1FB-8AE8B3E3704B.jpeg
