Extractor Fans & PIV Units for Mould-Free Homes
Struggling with condensation, damp, or black mould? We install professional ventilation solutions that tackle the root cause — not just the symptoms.
Why Mould Keeps Coming Back
Painting over mould or wiping it with bleach only hides the problem. Without proper ventilation, moisture builds up and mould returns within weeks. Here’s why it matters:
Property Damage
Persistent damp rots window frames, damages plaster, ruins decoration, and can even compromise the structural integrity of your home over time.
Health Risks
Black mould releases spores linked to respiratory problems, allergies, and asthma — particularly dangerous for children, the elderly, and anyone with existing conditions.
Rising Costs
Ignoring damp and mould means bigger repair bills down the line. Early intervention with proper ventilation saves you thousands in remedial work.
Extractor Fans — Targeted Moisture Removal
Bathrooms and kitchens produce huge amounts of steam and moisture every day. A properly installed extractor fan removes that damp air before it settles on walls and ceilings.
How Extractor Fans Help
Modern extractor fans are quiet, energy-efficient, and can be set to run automatically when humidity rises or when lights are switched on. We install them in:
- Bathrooms and en-suites
- Kitchens and utility rooms
- Internal rooms with no windows
- Shower rooms and wet rooms
Every installation is carried out to current Building Regulations, with proper ducting to the outside — not into loft spaces where moisture causes even more damage.
PIV Units — Whole-Home Mould Prevention
Positive Input Ventilation is the single most effective way to eliminate condensation and mould throughout your entire home — not just one room.
How PIV Units Work
A PIV unit is installed in your loft and gently pushes filtered, dry air down into your home. This creates a slight positive pressure that forces stale, moisture-laden air out through natural gaps and vents.
- Eliminates condensation on windows and walls
- Stops black mould from forming anywhere in the home
- Filters incoming air — reduces dust and allergens
- Virtually silent operation — you won’t know it’s there
- Low running cost — typically pennies per day
PIV is recommended by Environmental Health Officers and is widely used by housing associations and councils across the UK to combat damp and mould.
