Stamping out mould tips

[Solasum]

I am just buying my first house!

It has been rented out for years, and the tenants haven’t been great at keeping it ventilated, so there is some mildew in the odd corner/at the back of cupboards.

What is the best plan of action to prevent it coming back?

Will I need silica sachets in cupboards, or extra insulation?

@PigletJohn. And anyone else, please educate me!

ventilation.

Ventilation, dehumidifier if it’s really bad. You can get hanging sachets for wardrobes. Scrub any mouldy bits with anti fungal wash. Never dry anything over radiators.

Ventilation as others say, open windows (if possible - even just on a small gap) most days and keep curtains open. We have quite a bit of damp so use these in most rooms:

They are good for in cupboard/wardrobes or just in a damp corner.

Thanks all. So I just give it a good scrub, let it dry out then put in those absorber things? Sounds nice and simple.

Quite hard to ventilate a cupboard though?

dehumidifiers don't work if the windows are open, because they will try to dehumidify the world.

I'm most cases the temperature inside the house will be somewhat above the external temperature, even from solar gain, and ventilation will allow the internal moist air to escape.

You need both ventilation AND insulation. Mold will thrive when damp air can condense on a wall before it can circulate out into the open so making sure a wall isn't colder than the rest of the room is just as important as extracting the damp air.

We have freezing cold back walls that don’t get any sun on them in wintertime in our Victorian house which is why we also use the dehumidifier in the deepest winter (with the windows shut!) as our back bedroom radiator is right next to the door so the back wall stays freezing. We run it to get the condensation off the windows in the morning too. If we had windows open a lot in winter the house would stay far too cold all day. Spring summer and autumn I open windows.
