Condensation and mould fixes for Westbury homes
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.
