What the work involves
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 needs that damp surface to grow.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
