In Bletchley homes, black mould usually comes down to the same few causes: weak fans, loft-vented ducts and no background ventilation.
Whether the property is in the middle of Bletchley or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.

Condensation and mould fixes for Bletchley 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.
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.
