    We moved into our semi-detached council house almost a year ago, and there was some damp in the corner of the ceiling in main bedroom. I didn't realise what the story was with damp, but now it's slowly going across the ceiling and down the walls. I checked the attic for a leak and no sign, the timber just above the area looks perfect!! I also checked outside at the gutters etc... for a hole or somewhere for the damp to be coming from but can't find anything. Our neighbour joined to us has only a little in her hot-press, but that is not the room joined to our bedroom. Would anyone have any ideas what may be causing this and how I could get rid? The council wont do anything for us as it's not an emergency seemingly(!) although the timbers under our mattress was covered a few months back with mould. Any advice would be gratefully appreciated as I can't afford to get specialists in. Also it is not in any other room in the house.

    What size is the room? How Many sleep in it at night? Sounds like condensation not dampness especially after all the checks you have done...

    Is there any vents in the room?

    the room is about average, not awfully big, two in the room, myself an my boyfriend. the only ventilation is the thing on the window. didn't think of condensation as I presumed the mould would be around the window rather than in corner of the ceiling. would you have any idea what would be the best thing to get the black stain off the ceiling?

    is the shower on the other side of the wall, or do you dry clothes on the rads? its not damp. its condensation which is caused by poor ventilation. is the glass in the window wet in the morning??

    the black stuff is a fungus and you can get stuff in the hardware for mould/fungus. the council might have just painted over an existing problem before you moved in.

    its bad for asthma etc.

    leave the window open a little bit at night to let the air flow. you will have to get it sorted because its not going to go away by itself.

    strangely enough shower other side entirely. guessing it coming from bedroom window so, makes sense now! I know you're right about getting it sorted, must admit put my head in the sand when I moved in so dealing with it now. thanks a million for all ye're help, going to try tackle it tomorrow, let ye know how i get on!

    Best thing to get the black stain off is bleach. Put an old sheet under where you are working!

    I would get a dehumidifier and run it in the room during the day to suck the moisture out. I would also look in the attic and check the thickness of insulation above the spot where the mold is and add more if it is a bit thin.

    Do you have a lead valley in the roof above the bedroom??

    There may be a crack or hole in the lead valley that is letting in rainwater and this is dripping onto the ceiling below and then spreading.

    I had this problem and this is what eventaully happened to the ceiling,after the problem went undetected for a period of time.

    Problem was fixed with a new lead valley and ridge tiles,and a new bedroom ceiling,as the old ceiling literly crumbled and fell down on its own.:eek:

    Make sure you have mechanical ventilation in the room too (4 inch core hole through bedroom wall to outside/fresh air).

    The room needs to breathe. The problem was probably only tarted up with a clean and a lick of paint. Only lasts weeks at best before the mold resurfaces. You can pick up a mold/stain remover in Homestore for 7€. Its basically bleach in a spray dispenser. This is good for the quick removal of the mold but unless there is sufficient venting, it will be back. Avoid drying clothes on rads, open windows when possible. Get a vent installed. This should help greatly.

    Hi guys need your help

    We have noticed in the last week or so a damp smell in my little girl jaimys bedroom, smells like stagnant water but we can’t find any leaks or wet patches. Does anyone have any history or an idea what it may be? It smells like damp but we cannot find where it is coming from and it is only in her bedroom.

    Any help would be deeply appreciated and hope you don't mind
