mold on ceiling removal help DIY
Discussion
Hi All,
Bit of an odd one I know.
For some reason in both bedrooms in our house we have started to get small patches of what looks like black mould on the ceiling close to the outside wall.
We also see to be getting it on one of the down stairs walls, even though the house has been damp proofed down stairs.
Any idea what causes this and how best to get rid of it ?
Cheers
Michael

Water gets in one of five ways
Leaky roof
Poor damp course
Through porous brickwork
Badly fitting window frames
Poor ventilation leading to condensation
First things first, kill the mould with a caustic cleaning product like mildew remover. This will be very effective at removing the colouration too. Don't rub it in just let it soak in and do its job.
It sounds like you have a roof or gutter problem. Now it all depends how able you are to investigate and fix it yourself. If I were you I'd get some brickwork water proofer too. It's easy to apply and completely invisible once applied.

The black mould that you describe is a classic symptom of dampness caused by condensation.
The moisture in the air within your house, hits the colder outside walls, resulting in the moist air condensing back into liquid.
To cure this you need to increase ventilation within the affected areas (i.e. opening windows, trickle vents, etc.)

I'm guessing it doesn't help that we dry clothes in the room most affected 
Is one of those de-humidifier things the way forward

Or, turn up the heating in that room a little and place an ordinary fan in the room to move the air around.
My old house had the same problem and we increased air circulation and it worked fine.
Use a bleach to clean off the mould you have and re-paint with a paint that is suitable for a bathroom and is mould resistant.

I have this in my bathroom, I always have the window open to vent out the steam when I shower (easy ladies and boys of that nature!) but it still means I have loads of black patches, is there anything I can do to stop it happening so much? And please don't say take a colder shower as the 2 other people who use them it in the mornings like them very hot!!
