How we approach condensation and mould fixes in Knutsford
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.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.
Whole-home ventilation
PIV, continuous extract or MVHR where moisture is spread through the house.
