Condensation is one of the biggest causes of damp and mould in NI homes. We assess the airflow in your property and install ventilation systems that remove moisture at the source.
We solve:
Wet windows
Mould patches
Musty smells
Damp walls and ceilings
We supply and install high-performance ventilation units designed to increase airflow throughout the home. This improves air quality and prevents condensation returning.
Positive Input Ventilation (PIV) is one of the most reliable ways to stop condensation. It brings clean, filtered air into the home and pushes out stale, moist air.
Perfect for:
Older homes
Homes with poor airflow
Properties with recurring mould
We upgrade old, weak extraction fans with modern systems that actually remove steam before it settles on walls and ceilings.
Drimaster Heat – ideal for houses
Flatmaster / Flatmaster 2000 – perfect for apartments and flats
Nuaire Systems – advanced ventilation options for all property types
Every installation is tailored to your property.

A Drimaster is a Positive Input Ventilation (PIV) system that gently introduces filtered, fresh air into your home from the loft. It reduces condensation and humidity, which prevents mould growth and improves indoor air quality.
A Drimaster is designed for homes with loft space. A Flatmaster is made for flats or apartments without an attic — it draws fresh air from outside instead of the loft. Both prevent mould and improve air quality.
Yes — by lowering moisture and humidity levels, the system starves mould of the damp environment it needs to grow. In most cases, mould clears within weeks and does not return once ventilation is controlled.
Only 25p per week on average. It uses similar electricity to a low-energy light bulb — very efficient and designed to run 24/7.
Only the filter needs replaced every 5 years depending on your environment. No yearly servicing is required.
