Magnitude of the mould and moisture problem in Danish homes

The purpose of this study was to quantify the extent of moisture problems in Danish homes. Aquestionnaire-based survey was made and a representative sample of 3800 Danes older than15 years responded. Main results are that 17.6% of the people have had moisture damages intheir dwelling during the last 5 years and among those as much as 36.4% have not yetremedied the damages. A total of 17.7% have moisture or mould spots on their walls, ceilingsor floors. As many as 40.1% have mist on the inside of their bedroom windows during winter.A total of 91.5% of the people air out their dwelling daily by opening windows but 10.8%perceive noise, air pollution, risk of burglary or others as a barrier for sufficient opening ofwindows. A reduction of moisture problems are only likely to be achieved by a joint efforttowards ventilation systems, user behaviour, maintenance and source control.
