Humidity: Reducing the humidity in your home can have a noticeable impact, and the best way to do this is to review how you dry your clothes in winter. Hanging laundry in well-ventilated areas rather than warm rooms can help prevent mold and mildew. Also make sure the dryer is well ventilated to the outside. Other ways to reduce humidity in your home can include moving houseplants to less humid areas or removing them completely and upgrading the air extraction in your bathroom and kitchen to make them more effective.
Insulation: It is recommended that you fit your home with double glazed windows, wall insulation and crack sealing as this can also have a positive effect on condensation problems by reducing heat loss. Well-installed and energy efficient windows help maintain a high temperature inside, which can have a major impact on condensation and mold growth.
