    Hi guys

    One of my bathroom walls appears to have become damp or has something else growing on it?

    The bathroom has one window and every morning the window is covered in condensation to the extent that the window sill has a small puddle on it. So this may be the cause of the damp? Does this mean the window needs to be replaced? Its an old single glazing window.

    Or are there any other things I can do to get rid of this? I keep window closed during the night should it instead maybe be left open?

    Thanks.

    Do you have an extractor fan? Ventilation will get rid of the condensation which is encouraging the mould to grow.
    Bleech diluted will kill the mould, or one of the bleech spray cleaners. spray on, leave a few minutes, wipe with cloth
    Yes, keep the window open (slightly / on a catch) at night if you have no fan but don't get broken into if it's ground floor

    You do have a condensation problem rather than some other form of damp issue.

    A double glazed window would improve the problem of condensation on the window but that is all.

    There have been a number of threads on this recently and all come to pretty much the same answer.

    Heating and ventilation will help, so will extractor fans especially in bathrooms and kitchens. Finally a lifestyle change can have a positive effect to. The information in the first thread is pretty comprehensive.

    In your case a bathroom extractor fan with a timer delay on it could make a significant difference if the bathroom is the only room that seems to suffer.

    Blagard is correct, as a UPVC window will be more insulated (a warmer surface), all that would happen is that less condensation would form on it, however more condensation will form on the walls (making the mold problem worse) and in other areas of the house. To be honest I would still expect the upvc window to end up dripping with condensation, but maybe not as much.....

    I'd also get rid of the carpet too (if that is one) as that'll be holding onto moisture.

    Good point dormermike....I did not notice the carpet in his picture

    ....carpet in the bathroom is not usually a good move....to be honest neither is wallpaper, especially wallpaper with that type of textured pattern. It will just give more surface area for the water to condense on, get trapped on and get soaked in to the paper and turn to mould......

    When you can, I would just tile the whole bathroom. Or part tile and strip the wall paper back to the plaster (if in good condition) and paint with appropriate bathroom paint.

    Thanks for the replies guys.

    Yes the whole bathroom has carpet (it was like that when we moved in).

    We are looking to strip the wallpaper and carpet soon and tile the walls and floor.

    I think in the meantime I will look to keep the window slightly open at night. As I do not think there is much point in getting an extractor fan and then removing it when we tile the bathroom.

    Sounds like a good plan.

    Definitely worth installing one when you do the bathroom. Just ensure you choose one that has a humidistat (so it continues going until the humidity is at a good level).

    In the mean time, ensure the window is open when using the bathroom and open a crack at night....
