Damp or mould!?

[potato80]

Hi all

I think the attached pictures show just basic mould rather than damp. Am I right?

if so, is it just a case of mopping up the excess water that collects around the window, and keeping the window ajar slightly?

4 hours per day using the dehumidifyer doesn't seem to do the trick (according to tenants)

The pictures are taken in the first-floor bedroom.

There is no extractor in the bathroom.
There is an extractor hood in the kitchen.
Clothing is dried in the living room on a rack.

Many thanks

Mould requires damp, caused here by lack of ventilation and drying clothes indoors.

The dehumidifier won't work, as the windows are old aluminium ones with no thermal break - the inside metal frame will be the same temperature as the outside air and moisture will condense on the metal frame rather than anywhere else.

Bathroom needs an extractor. Kitchen one must be vented outside. Drying clothes inside must stop. If a tumble dryer is considered, that must also vent outside.
Otherwise it will be damp and mouldy for ever.

It's strange but in my experience, tenants produce more mould and damp than anyone else.

Thanks for the replies; really helpful, esp the part about aluminum frames.
I'll get an extractor and just keep the window ajar and mop up condensation for the time being
