    You need to do two things:

    1. Remove the actual mould from the wall. - Scrape off the paint (with mould on it) completely. Then coat the wall with the mould remover/retarder and then repaint, ideally with mould resistant paint.

    2. MUCH more importantly - Remove the reason for the mould.
    a. Cleaning the gutters may have helped.
    b. Reduce the amount of moisture in the room by opening windows regularly, make sure all your room vents are open and unrestricted, ensure bathroom and kitchen fans are used all the time, no drying clothes inside, doors closed and windows open when showering, etc.
    c. Check to make sure you have no leaking pipes inside or out. Also check for blocked drains below ground!
    d. The mould started in that location because it's the coldest place and the moisture from inside is condensing there - e.g.: missing insulation, ground level issue outside

    Removing the mould will do very little unless you address the root of the problem which is excess moisture and/or poor ventilation!

    Look at investing in a dehumidifier.

    We had a lot of condensation on our windows in the morning, which was leading to mouldy spots on the roof.

    Purchased a dehumidifier last week (plug in ones, expensive enough) have it timed to come on during the night & it stopped the condensation problem.

    Hi,

    We had some damp on our walls a few months back, we bought the house in mid 2016.

    I'm worried about having it sleeping in the room.

    ]
    How old is the house?, where is the mound?

    Since I've got to know the lads here and their experienced professional opinion on mould, damp etc I've become fastidious in opening opening window vents in the morning in ours and the kids room. In warner weather they remain open. Also keeping the door to the en-suite open and the bedroom window open after shower etc. They'll give out to me but I do dry clothes inside but again I keep vents of Windows open for a couple of hours monimum to try and keep the place well ventilated. We've had mould before, and these measures seem to be keeping it in check. Now the lads may well give out to me for it but it has worked for me.

    You could consider a Positive Input Ventilation System Such as : https://www.beamcentralsystems.com/positive-input-ventilation-piv
    You can put it in yourself if you want, or theyll do it for you. Great job in my house. Keep an airflow going at all times. There is a wee heating element in it too in the event the attic temperature drops below 8degrees or so (from memory). Just a fan installed in teh attic with a vent in common/landing area.

    How much is it for the unit itself?

    I'm deciding between that and a dehumidifier

    A dehumidifier is not a solution. You need to address the problem. it sounds like a lack of proper ventilation.

    I have the wall vents open all the time and mechanical extraction in the kitchen and bathroom

    I have a build up of moisture on the windows since I got the house insulated

    Would the solution be to open the windows for a while in the mornings

    I have just had PIV installed in my house (in the last month). Seems to be doing a great job in eliminating condensation.

    How much airflow is there through the PIV vent?

    Do you have vents open on the walls?

    I don't know! There are 3 settings. It's just on 'trickle' at the moment and that seems to be doing the job.

    I'm dubious all the same

    Wouldn't you get the same effect opening the letterbox and the wall vents( for free)?

    Probably, but only really effective when it's windy!

    The letterbox and wall vents did not stop condensation and mould starting to grow in my house.

    This is what I had installed: http://www.envirovent.com/specifier/products/positive-input-ventilation/piv-loft-mounted-unit/

    No. Its forced ventilation. Need to ensure openings under doors are adequate, or leave doors open. Total cost of about €450 for me and about 5 hours installation. Someone who is used to it will probably have it in in an hour or 2. I put two outlets, one in my kitchen and one in my hall so I took longer. It is no solution to the damp issues I have, but it elimiates the mould growth. I will definitely be taking it out and installing into my new build, whenever the money fairy leaves the suitcase of money at my door soon.
