One of the most common causes of dampness in buildings is ‘condensation’.
What is condensation and how does it occur?
Condensation dampness is a condition that affects many homes and has become a major cause of environmental dampness within properties. Condensation is particularly common in homes which are poorly heated and poorly insulated and usually gets worse in the colder winter months i.e. ’the condensation season’.
Quite simply, condensation is water that is released from moisture laden air (When the dew point is met) and deposited on cold surfaces and is usually seen as a problem during the colder winter months. It is often seen on windows being more noticeable on cold mornings, and possibly on external walls.
Condensation is also found where air movement is restricted, such as in corners of rooms, behind items of furniture placed against walls and even in wardrobes or cupboards. Its presence can be first indicated by the development of black spot mould growth on walls and ceilings, and even furniture, clothes and other fabrics.
How do you solve condensation problems?
In order to keep a property free from condensation/high atmospheric moisture levels, there needs to be a good balance of heating, good insulation, ventilation and reasonable moisture production.

We offer a range of positive input ventilation systems (PIV Units) to suit most property types.
Each property is unique and should be carefully surveyed by a ventilation surveyor to check it is suitable for the installation of a PIV unit.
Where a property is not suitable, we may have other ventilation solutions which could be installed, such as extractor fans and alternate flow fans.
PIV units have been preventing and curing condensation dampness related problems in homes for decades. They are also used to control other indoor air pollutants and have even proven to be an effective means for reducing Radon gas in some properties.
A positive input ventilation system gently forces air from the loft around a building (Roof Type). It reduces humidity and eliminates condensation, black mould and mildew. It is an effective and inexpensive way of eliminating black mould and takes maximum advantage of solar gain and warm air stratification.
Overall savings in central heating costs may be possible due to the recirculation of warm air at ceiling height.
The units are idea for most domestic properties, and also for second or holiday homes that are used infrequently.
The roof type PIV unit is positioned in the loft above the landing in a house or central hallway of a bungalow, the system then re- circulates air around the property.
For buildings without a roof space, a wall mounted PIV unit is available. The unit is normally placed within a central hallway.
We use a number of different types of PIV units, all of which have different features (Heaters etc).
As mentioned above, all properties are unique and therefore it is important to make sure that the PIV unit being installed is suitable for the property.
When we undertake a ventilation survey, our surveyor will discuss the different types of units to help you decide which is best for your property. Information leaflets are available to download below for some of the PIV units that we install.
