Condensation and mould ventilation fixes in North Yorkshire

In North Yorkshire homes, black mould usually comes down to the same few causes: weak fans, loft-vented ducts and no background ventilation.

Across North Yorkshire the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Selby, Thornaby-on-Tees, Yarm, York and Middlesbrough.

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. 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.

Whole-home ventilation

PIV, continuous extract or MVHR where moisture is spread through the house.
