Ventilation, Extractor Fans & PIV
Most mould problems we see are caused by condensation: warm, moist air from cooking, bathing and drying clothes settling on cold walls, ceilings and window reveals. When a home cannot get rid of that moisture, surfaces stay damp and mould takes hold.
Improving ventilation is often the single most effective way to stop condensation-led damp and mould for good. We assess how air moves through your home and fit the right combination of extractor fans, Positive Input Ventilation (PIV) and trickle vents, alongside anti-condensation measures for cold surfaces.
What's Included
- A full assessment of moisture production, air movement and cold surfaces in the property.
- Installation of Envirovent extractor fans in bathrooms and kitchens.
- Positive Input Ventilation (PIV) systems to bring filtered fresh air into the whole home.
- Trickle vents and anti-condensation measures, including graphite thermal liners for cold walls and ceilings.

Signs & Causes
Condensation is the most common cause of damp and mould in UK homes, and it is almost always a ventilation problem at heart.
- Streaming windows and wet sills in the morning, especially in bedrooms.
- Black mould in corners, behind furniture and around window reveals.
- Musty smells and a general feeling of dampness in the air.
- Moisture from cooking, bathing and drying clothes indoors with nowhere to escape.
- Blocked, broken or missing extractor fans and vents.
How We Treat It
We match the ventilation solution to the property, so moisture is removed at the rate it is produced.
- Envirovent extractor fans fitted in bathrooms and kitchens to remove moist air at source.
- Positive Input Ventilation (PIV) units, usually in the loft, that gently push filtered fresh air through the home and force moist air out.
- Trickle vents to give background ventilation in rooms that need it.
- Anti-condensation and graphite thermal liners to warm cold surfaces so condensation is less likely to form.
- Practical advice on managing moisture day to day.
