Mould
Mould grows where damp sits for long enough: on cold walls, behind furniture, in wardrobes and on window seals. Cleaning it off is only half the job. If the damp stays, the mould comes back, so this section pairs safe cleaning steps with fixing the cause.
We don't make health claims. If you're worried about how mould might be affecting you or your family, the NHS has guidance, and your GP or NHS 111 can help.

Before you clean
- Find the cause first: condensation, a leak, or damp coming through a wall or floor. Our condensation guides help you check.
- If you rent, report it to your landlord in writing before you clean, and take photos. See renters and landlords.
- Never mix cleaning products, and never mix bleach with anything else.
Keeping it away
Most returning mould is a moisture problem: more ventilation, less moisture made indoors, and steadier heating. A dehumidifier can help in a room that stays damp after those steps.
