    I have minimal levels of damp in one corner of the front room (bay window, front of house on external wall).

    I've moved furniture and curtains as much as possible but I think the area will always suffer so I'd like to try something a little better.

    What's the least intrusive method for fixing this? I want to try and avoid re-plastering and limit it to patching-up.

    I considered something like a hit and miss vent but they all seem like big holes to punch through the wall.

    Would drilling a few holes and finding a tidy way to cover be worth it?

    What sort of damp? Black mould damp or yellow and white stain damp?

    Could be caused by a leak or by condensation.. Sort that first, or any remedial works will be temporary

    I know the cause, it's the external wall with poorly circulating air.

    By drilling holes through the wall and covering with a grille, is this likely to resolve the issue?

    How do you know now if you didn't know on sunday?

    The cause of the "damp" has not been nailed down, it could be a mixture of rising damp, penetrating damp or most likely, as above, condensation.

    Why not post pics of the outside & the inside of the wall.

    Installing a vent could possibly make it worse. sounds like condensation on a cold wall to me.

    I'll get some pictures - what in particular would help establish the issue? Just a couple of shots to indicate the construction and area?


    I'm pretty sure it's poor circulation: corner of the ground floor, front bay window, slate DPC with a solid wall. Property built 1916. Happily take advice on it and being wrong though.

    Just stick some polystyrene paper on it. It'll cure the problem.

    No - no water comes down there. If it is water damage its an old issue.

    Any ideas on a fix?

    Is extra ventilation a good idea?

    No.
    Its condensation on a cold wall, a vent will make the wall colder.

    You can try what joe suggested.
