[mum of 2]

When we moved into our house 3 years ago all the walls were covered in wallpaper think that was so we didnt notice the damp problem. It is really gettin in the way we have put air bricks in but haven't seemed to do anything, it is really bad especially in one of the bedrooms that we were supposed to be turning into a nursery for our 6month old daughter whos had to stay in our bedroom now, it has mold all over the external walls and the double glazed window has even got it, it smells in there it is discusting not a place for a baby to sleep HELP please really need to get this house sorted out, would really appreciate your help and advice. :(

Hi,
Its a common problem with certain houses.

1.Have you took the wallpaper off the walls and its still on the plaster??
2.Is it just on the external walls only?
3.Do you have a radiator in the room?
4.Is it just upstairs bedrooms that suffer?

It could be the guttters, it could be condensation, poor ventilation, pointing could need doing on outside brickwork.

Mould and damp occur because of poor ventilation and increase with the aid of central heating to clear this problem you need to regulate airflow in each room.You need to have trickle vents fitted on each window and leave them open.To clear the mould use neat bleach and a sponge to clear the spors and use a dehumidifyer to erase the damp.
