Black Mould, how do you kill it?

As per title, how do you get rid of that pesky black mould? We had a leaking pipe and now the ceiling is infested with the stuff. Also, is it dangerous?

The black mould appears to live in gypsum that cannot breath. I have seen it in gypsum plaster that was behind drylining and in glazed plastering. My advice is to pull down the ceiling and get a good plasterer to put up a new ceiling. It will cost about 500 e. 2 men @200 each for the day and about 100 for materials.

Link not working. Is there any other way? Any spray or disinfectant? It would mean re-doing most ceilings in the house, and some of the wall studding too! Is it dangerous to peoples health?

You can get mould remover to clean it off, but there is a chance of it re-appearing if its well into the plaster....

Dettol Mould and Mildew Remover?

Ordinary bleach kills mould - make sure you take steps to prevent it from getting into your eyes/lungs though.

dettol mould and mildew remover is excellent at this. widely available and super effective. spray, leave a few mins then wipe away.

Make sure you open the windows and wear a pair of overalls when you use it.

HG mould spray should do the job: http://www.amazon.co.uk/HG-Hagesan-Mould-Spray/dp/B000IU40HQ

Mould remover sprays can be found in supermarket. Protect eyes and take care not to inhale. Open windows and do in small sections.

Yes black mould is bad for your health. The spores from same can cause allergic reactions/asthma/breathing problems.

Improve ventilation/heating of areas in future. Better to have constant low level heat rather than extreme temps that allow for moist air to condense on cold surfaces. Best to shift damp air directly with use of extractor over cooking area or shower. Or could use a dehumidifier machine running in winter if ventilation is a problem ( see Argos). Open windows regularly, check out air vents perhaps extra one needed somewhere? If upper rooms have mould on ceiling, check out insulation above in attic.

Post some pics of the damaged area(s)

Is it the whole ceiliing or just the corner of the room. Depending on the extent of the damaged area you might be able to cut away the bad plasterboard and put up new board + skim that area. But again it all depends on the extent of the problem... if it was just the corner of the room i wouldn't be pulling down the whole ceiling.
