Dealing with damp and mould
If you notice mould growing in your home, you can treat it with a suitable fungicidal wash (available from most DIY stores), and following the manufacturer's instructions. Keep checking the affected area for at least a week. If the mould reappears, wash it down again with the fungicidal wash to make sure the area is thoroughly sterilised.
When redecorating, use a good quality fungicidal paint to help prevent mould growth from returning.
