Condensation will be present to greater or lesser degrees in all properties. In most cases the problem is managed, and not damaging. However, condensation can cause considerable damage if not controlled.
- Cause: Condensation occurs where warm air meets cold surfaces and there is inadequate air circulation to dry the resulting droplets. Heating and cooking with inadequate air circulation will cause condensation, but even normal breathing can cause an accumulation of moisture in unventilated properties.
- Symptoms: Excessively wet ‘hard’ surfaces including windows, fridges and walls etc. In bad cases black mould will appear, usually in corners or behind curtains and furniture where air flow is restricted.
- Prevention: Increase air flow. Open windows where possible, ensure that the air vents in windows and patio doors are open. Ensure that extractor fans are clear and free of dust.
- To reduce the risk of condensation build up:
- Where possible, keep windows open to ensure air flow.
- Remove excess moisture by wiping windows dry. Do not allow water to pool.
- Do not place furniture or materials so close to walls that air cannot circulate.
- Be careful where you dry wet wet washing and ensure windows are open.
- Ensure that water tanks have the protective lids in place.
- Do not place soft furnishings in close proximity to water tank cupboards.
- To remove condensation mould, wipe clean with a very diluted (1/20 part) bleach and water mix and soft cloth, or use a proprietary mould inhibitor. Do not use neat bleach; it will take the paint off.
