Controlling condensation in a bathroom

The practical points
- Extraction with an overrun clears the moist
- air before it reaches cold walls and windows.
- Cold spots behind furniture or on uninsulated external walls are where mould starts
- so airflow and insulation matter together.

Common questions
Is mould always a damp problem?
Not always, surface mould from condensation is different from penetrating or rising damp, and the fix differs.
Does a dehumidifier help?
It manages symptoms; extraction addresses the cause at the moment moisture is produced.
