Damp Proofing Question

Black mould in 1st floor master bedroom

We redecorated the master bedroom on the 1st floor in Jan 11. This winter we have developed black mould in the northen most corner of the room, starting from the deling and slowly traveling down the corner. we have also noticed aslight colour change all down the corner, feeling slightly damp. We went into the loft and didn't notice any mould on the roof beams, but did on a few suitcases stored there. We didn't notice any gaps in the roof either on the inside or outside. What is causing it and what can we do to stop it.

best thing is to get the roof inspected and see if theres anything wrong up there other than that it could be you have a condensation problem you need some on to come and have a look

I would recommend you obtain specialist advise from a fully qualified surveyor.A CSRT surveyor will offer candid aand accurate advise to the customer.There is normally a small charge for his time and experience.

Hi Fiona
If black mould is present then it is highly likely to be from condensation. This occurrs when moist air within the home comes into contact with a wall that has a cold enough surface temperature for condensation to occurr. I have surveyed at least 50 properties this winter with this problem - the most common defining factors are the drying of clothes indoors and lack of ventilation from cooking / bathrooms so look at these first.
The good news is that from April to October this is unlikely to happen due to warmer walls.
