‘Condensation dampness’ is a condition that affects millions of homes, all air contains a certain amount of ‘invisible’ water vapour, the warmer the air the greater the amount of water vapour that can be held. It is particularly common in houses which are poorly heated and insulated i.e. have more cold surfaces, and usually gets worse in winter.
This problem can lead to staining and mould growth, damaging wallpaper, wall surfaces, window frames, furniture and clothing. The development of mould growth is the most tell-tale sign that is frequently associated with condensation. The appearance of the mould may be black, white, yellow, green in colour, depending on the specific type of mould and the surface on which its growing. The tiny spores produced by this mould and higher numbers of dust mites due to the moist conditions can also increase the risk of illness such as asthma and bronchitis.
MacLennan have a range of methods for dealing with the cause and effects of condensation.
Our experts install Passive vents which cause moist air to escape without allowing draught.
Whole house positive pressure systems can be installed which utilise warm air from the roof void and cause air to move out of the building removing the moisture laden air.
The MacLennan mould kit is supplied to the home owner, councils, housing associations. It is used to remove the mould growth and as an additive to paint to prevent the re growth of mould.
