Is Condensation Causing Damp Walls?
Condensation is the most common form of dampness in properties, and left untreated it can lead to black spot mould, peeling wallpaper, damage to fabrics, as well as a cold house with an unpleasant smell.

Health implications of condensation

Dampness caused by condensation is not only detrimental to the property’s structure, but also has health implications.

Condensation is more common between October and April, when the temperature difference between the warm air in the house and cold outside is greatest. The key to reducing condensation is to ensure sufficient ventilation and to ensure the external walls of the property are not damp, as a damp wall is a cold wall, due to the air spaces within the wall material being filled with water, a poor insulator, instead of air, an excellent insulator. 

A few handy tips to help prevent condensation

When cooking, use an extractor fan, or open the window if possible.
If you can’t open the windows for ventilation, ensure trickle vents are open.
During showering, ensure the extractor fan is operational and the window open if possible. Keep the bathroom door closed as long as possible to ensure excess moisture does not escape to other parts of the property.
Ensure that the tumble dryer has correct adequate ventilation to the outside of the building.
Install humidistats to control the humidity within the air.
