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.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.
Mould treatment advice
How to clean and treat affected areas once the cause is fixed.
