How to remove mould safely, stop it coming back, and deal with it on walls, window seals and clothes.

Mould and damp can affect anyone's health, and especially babies, older people, and people with asthma, allergies or weak immune systems. If someone in your home is unwell, see the [government guidance for England on the health risks of damp and mould](https://www.gov.uk/government/publications/damp-and-mould-understanding-and-addressing-the-health-risks-for-rented-housing-providers/understanding-and-addressing-the-health-risks-of-damp-and-mould-in-the-home--2) and talk to your GP.
