Condensation
Condensation is a common problem in properties of all types and ages.
It can contribute to the creation of black spot mould.
Condensation can also be present where there is no noticeable mould growth, such as in roof spaces and sub-floor voids. This may lead to more moisture within structural timbers, making them vulnerable to fungal attack.
Causes of condensation
Condensation is water that is created when excess moisture in the air comes in to contact with cold surfaces. Moisture can be produced by cooking, bathing, and drying clothes.
It occurs as a result of an imbalance between moisture vapour in the air, ventilation, heating, construction type and surface temperature.
Reducing condensation in your home
To reduce condensation in your home you should:
- try to avoid drying clothes on radiators as this can release moisture that forms condensation on walls
- open your windows and cover pans when cooking
- run cold water into the bath before adding hot water
- try to keep air vents in walls and doors free
- try and ensure your tumble dryer is vented to the outdoors
- close your kitchen or bathroom door when using extractor fans
- avoid overfilling your wardrobes and cupboards and move furniture slightly away from the wall
- open your windows regularly to replace damp air with dry air, especially in the morning
- use an anti-mould spray and wipe areas of condensation before it can build up
