Do you suffer with black mould and condensation problems we can help eliminate this.

Some properties can suffer with black mould issues and condensation problems leading to unheathly living conditions and cause heath problems long term.


As condensation season comes into effect starting from late September through to Febuary the misery of waking up to to soaking wet windows and damp smells thoughout your property is a serious one.

We also supply and fit Positive Input Ventilation units also known as PIV units and these are a lasting perminant solution to condensation and damp problems, see some examples below of ones we recently fitted.

Positive input ventilation unit roof mounted in a loft

Here we have a roof unit that mounts in the loft space creating a postive pressure of air into the house which creates a heathy atmosphere and eliminates condensation and mould problems due to lack of ventilation in modern homes. It often becomes a massive problem for home owners when the colder mornings arrive during condensation season (October to February)

Passyfier Air Vents supplied and fitted from £195.00






Passyfier air vents aid the removal of moist air from the room to the outside. The Passyfier is different to standard air bricks as they prevent cold air/ draughts from coming into your property.


This is because the passyfier is fitted with a slab of mineral based wool inside which prevents the cold air and draughts coming in but will allow the moisture out helping control moisture levels.


It operates continuously and can help extract up to 2.1 litres of water per day.


The passyfier requires no electricity and is inserted in the wall where the problem exists.

These can be fitted in most rooms in a property neatly with no mess or disruption to your property.
