Mould / condensation
Once a serious ongoing dampness problem has established itself in the home mould fungus (mildew), a parasite freely available in the air pollen yeast etc, can develop on walls, furnishings, bedding clothes, leather goods, shoes and handbags etc.
Mould first appears as spots or small patches which may spread to form a furry layer usually grey green black or brown in colour.
Three conditions are necessary for mould growth.
1. A source of infection – spores – are present in air.
2. Dirt, dust, grease or some organic material is needed in small amounts so almost all surfaces will sustain growth.
3. Damp environment in excess of 85% humidity for periods of over 12 hours daily, it is also more marked in north facing walls.
Limiting condensation risk:
• Contain steam at source. (keep lids on saucepans)
• Minimise the use of oil and gas heaters.
• Increase ventilation levels. (ventilation to all rooms so moist air can escape)
• Maintain reasonable levels of heat.
• Avoid drying clothes indoors.
