I live in a semi-detached house and the 3 bedrooms upstairs that face the outside walls have white mould not the dark black stuff over the walls i have cleaned it with bleach but it just keeps coming, its not so bad in the summer but the winter it's worse which then gets in the wardrobes and all sorts
So i am after some advise really -
The windows in 1 of the bedroom's are really old they are wood frame double glazed windows that have a lot of condensation on which i try to wipe up as best i can.
In bedroom 1 it has a 600mm high radiator by 900mm wide, the size of the is room is approx 13ft by 14ft with brand new windows (not much condensation on them) or mould on that wall but the side wall collects a lot of mould.
In bedroom 2 it has a 600mm high radiator by 1200mm wide, but this room as a stud wall in it to create 2 bedrooms the window wall (old windows soon to be replaced in Jan) has spots of mould on it but
In bedroom 3 it has no radiator loads of mould in the corners of the room, each side of window wall (again old windows soon to be replaced in Jan) and the external side wall as well has loads over it.
sorry to drag on, now my question is once i have the new windows installed if i put a bigger radiator on the external wall's in bedroom 1 & 3 will that keep the wall's warm in the cold weather and stop mould spores collecting on the wall or put plasterboard on both side wall's so it does not get too cold or both radiator & plasterboard in both rooms or maybe another solution
i am stuck for answers on this issue and its really getting me & my wife down.... Thanks for reading
