How do you stop condensation and black mould? Condensation is stopped by reducing moisture in the air and improving ventilation: extractor fans in kitchens and bathrooms, positive input ventilation (PIV) units, better heating balance and treating cold spots. Existing black mould should be professionally cleaned and treated with fungicidal products to stop regrowth.
Signs of condensation and mould in your home
Caught early, condensation and mould is far cheaper to fix. If you recognise any of these, it’s worth getting a local expert to take a look — our advice is free.
- Black spot mould — clusters of black mould in room corners, behind furniture and around window reveals
- Streaming windows — heavy condensation on glass and frames every morning
- Musty smell — stale, damp air — especially in bedrooms and bathrooms
- Mould on belongings — mildew appearing on clothes, shoes or furniture in cupboards
- Peeling paint near ceilings — damp patches on cold external walls with no tide mark
- Worse in winter — the problem appears when heating goes on and windows stay shut
What causes condensation and mould?
Every household creates moisture — cooking, showers, drying laundry — around 10 litres of water vapour per day. When warm moist air hits cold surfaces like external walls and windows, it condenses. Without enough ventilation, that moisture feeds black mould (Aspergillus niger), which can aggravate asthma and allergies.
Modern draught-proofing, double glazing and disused chimneys make Sussex homes more airtight than ever — great for heating bills, terrible for ventilation. That's why condensation is now behind the majority of 'damp' complaints we survey.
