How to prevent mould in winter

[hoomama]

Every year, as soon as we put the heating on mould starts developing on the ceiling and around the windows upstairs.

I open the top windows a tiny bit to let some air in. I also dry some clothing in the house which I know is probably not helping.

The bathroom has a dehumidifier fan and I try to make sure the door of the bathroom stays closed after bathing etc and leave the window wide open.

Am I doing something wrong here?

Sorry to be dim here- but what does a window vac do that just wiping away the condensation with a cloth doesn't?

Is quicker, and doesn't leave streaks.

Bleach does kill mould. Buy a proprietary mould remover (eg the HG one) and you’ll find out that it smells just like bleach.

Get a decent dehumidifier, perhaps even two, one for upstairs and one for downstairs.

Get a much more effective bathroom extractor and one for the kitchen too. Find out how much water they claim to remove per hour. Get the most powerful that you can afford.

Finally, if funds allow, get a positive input ventilation system installed. This constantly pushes air around your house and the damp doesn’t get time to settle (if that makes sense). Mine was about £3k including installation but you could cut costs by installing it yourself.

If you’re in SE England then message me and I’ll send you the name of the firm that put my system in, plus extractors. Absolute game-changer for my house. Before that, my walls were going black and I’d lost clothing that had been in a wardrobe which was up against an external wall.
