    Furniture gets mould on it, when placed against external wall.

    I live in a 1930's rendered semi and any furniture I put against an external wall gets mould all over the back. Does this happen in other houses?

    it happens in all damp houses

    If it is rendered and has had a damp course put in then I would imagine the damp is coming from underneath the foundations, maybe something to look into?

    But then again, mould is normally down to bad air flow, check the air bricks, if they are blocked then that could be the cause.

    What about moving the furniture away from the wall slightly and putting one of those dehumidifier boxes you can buy in pound stores with the granules behind the furniture and see if any water gets collected.

    The house was really damp when we first moved in, we have improved it loads. Will look at air bricks, that might be the reason. It tends to be worse in the warm months when the heating isn't on. Thanks NEtech!

    open a window when its warm

    Condensation? We sometimes get mould on the walls in the corners of the room throught the winter - it leads off the kitchen and so gets steam etc, This has actually been better since we had an extractor fan fitted in kitchen,

    We did use a dehumidifier a few years ago, it collected loads of water until it broke! We tend to avoid putting stuff against the external walls but obviously it is a bit limiting. I asked really because we are going to move to a newer house and wondered if we would have the same issues!

    its the steam that's causing the mould if its trapped in the house, so of course its better with a extractor fan fitted

    so rather than replace the dehumidifier you thought lets live with the mould instead
    a new house will/should be better ventilated but if that ventilation is blocked you will get the same problems

    probably condensation due to lack of air movement behind the furniture, move it away from the wall a bit to allow airflow, also, if the house has been damp it can take a long time for the walls to dry thoroughly so make sure it is well ventilated

    Agree with the lack of air circulation - I live in a barn conversion from 1800 and there have been many damp issues. We leave the windows on vent all the time and open them whenever we're in and it's not freezing! Also, use a dehumidifier if you ever dry washing inside, as that creates masses of damp air throughout the house, which just makes the issue worse.

    Thank you all. We had 2 dehumidifiers over time, but after they broke we changed the way we dried clothes, kept windows open and even used open fire in the summer so we thought that should solve the need for another one!

    I live in a damp area (houses built on old flood plain) so we suffer a lot with damp, condensation etc

    Replace your dehumidifier is a priority (once damp is in it's more difficult to remove
    When taking showers use extractror fan or open window
    When using tumble dryers make sure it's vented outside
    During warm weather open a window or use extractor fan to circulate the air (remember heat and steam (hot moist air will rise)
    Then during the autumn/winter months use you dehumidifier a few hours each day

    We never stopped the condensation because of the location but we did stop mold

    I have had a few houses and only my bathroom in one house has a mold issue. the rest were all well ventilated.

    When we moved here last year damp/mould in the bathroom was an issue, however that was down to the "intelligence" of the previous occupier as they had in their wisdom decided wallpaper in a bathroom was a good idea and then made it worse by having overlaps of about 4 inches that wasn't pasted down so this wicked the water behind the paper which couldn't evaporate as it was a vinyl, you can imagine the fun of stripping that off and revealing what lay hidden. Once stripped though the walls was lovely and smooth underneath.

    Trust me I know about this for a long time I lived in a badly converted chapel with a leaky roof
    I have all my furniture 4 inches from the wall
    treat with mould killer

    as above keep well ventilated
    Use your central heating no matter how broke you think you are 15 minutes twice a day minimum

    It's condensation.

    You're trapping warm moist air next to a cold external wall, causing water to condense and providing an ideal environment for mould growth.

    I'm a single mum and had this problem in my sons bedroom only it was with his bed. My friend offered to loan me a dehumidifier for a weekend. What a world of diffrence. The thing holds 2L and I had to empty it about 3 or 4 times a day for the first week. I ended up keeping it two weeks and had it on 24/7. At the end of the two weeks I went out and bought one myself I use it now once a week in my sons room and put it on for one day in the kitchen and one in the bathroom. Cost me about £99 from argos, but was honestly worth every penny. No more damp clothes, no more mildew smells. No more damp cold feeling walls and now when I do put the central heating on it really does warm up the walls! I also live in an old house and over time the moisture builds up, it's no ones fault exactly it's just life . Happy to say it's easy to treat if you can't afford to buy one someone in your area may loan you one for a few weeks. The other options are treatments that mask the problem. Hope this helps and you get it sorted soon.

    mould can be deadly so you need it sorted.

    Thanks for the advice, will see if I can borrow a dehumidifier for a bit!

    My mate works in local authority property Dept and he said to open your windows for at least a hour every day, ideally in the morning to let air flow through the house. Helps to combat damp, condensation etc.
