Mould in plaster-work - how can I cure it?

[LeanTwo]

I'm installing some new windows and one of them is in a bathroom.  I will have to remove some of the old plasterwork inside as the new frames are deeper than the old ones.  The new sashes are double glazed so I'm hoping that condensation issues in the bathroom may be reduced.  However, what has happened over the years with the single glazed windows is that black mould has taken up residence in the plaster around the window and in the ceiling above.  Is there anything that I can do at this stage, whilst I'm doing work to get rid of and prevent the mould returning?

This stuff. Fairly evil. Be careful if you have any respiratory problems. 

Get the wife to use it. 

Cleared ours up no probs. Or just use a bleach solution and clean off and dry thoroughly before re decorating. 

The main thing is good ventilation and air movement. 

Have you a good extractor.

I also used the same spray in my old house and as mentioned don't breathe it in. Once cleaned off I used this paint to cover it up and it never came back in the 3 years before I moved out. It's expensive but it works.

If you are not properly ventilated the condensation will migrate somewhere else because the air seal will now be better.

 

Or you will have to run it at a highe temperature to jeep the moisture in the air.
