What the work involves
A typical family puts several litres of water into the air every day. If extract fans are weak, ducted into the loft or switched off, and windows stay shut in winter, that moisture settles on the coldest surfaces: window reveals, external corners, behind wardrobes and on bathroom ceilings.
Mould treatment advice
How to clean and treat affected areas once the cause is fixed.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.

Rules that apply in Wales
In Wales, ventilation follows the Welsh Approved Document F rather than the English version, with building control checking notifiable work. Rented homes in Wales must be fit for human habitation under the Renting Homes (Wales) Act, and damp and mould is one of the matters considered.
