Mould behind furniture is extremely common in UK homes because airflow is restricted. Moist air becomes trapped between the wall and the furniture, creating the perfect environment for mould growth.
Why mould forms behind furniture
- Cold exterior walls.
- Poor air circulation.
- High humidity in bedrooms and living rooms.
- Furniture pushed tightly against the wall.
How to prevent it
- Move furniture five to ten centimetres away from the wall.
- Use a dehumidifier to keep humidity around fifty percent.
- Open windows briefly to ventilate the room.
- Clean the wall and furniture with an anti mould spray.
Extra tips
Wardrobes and drawers placed against external walls are more prone to mould. Consider placing them on internal walls instead.
Once airflow improves, mould behind furniture usually stops returning.
