Why Does Condensation and Damp Get Worse in Winter?

By EnviroVent Feb 06, 2012

Do you have streaming windows, or, even worse, walls? Has the growth of black mould started to appear around your window frames and on walls? These are the tell tale signs which signal that your home may be suffering from condensation. Unfortunately, homes are prone to condensation even more during the winter months as there is a great temperature difference between the warm interior of your home and the cooler outdoors. Cold weather usually tempts homeowners to conserve as much heat as possible in order to stay warm, which means that the warm air circulating around your home has no way of getting out. Because of this, condensation will begin to form on surfaces that are below the dew point of the surrounding air. So, what else causes condensation to occur as soon as the weather gets colder?

  • Traditional heating methods such as radiators and fires are a major attribute to indoor humidity. During winter, homeowners are more likely to depend on these traditional heating methods in order to stay warm, therefore producing and transmitting more moisture in the air.
  • Radiators may be kept on during the day in order to dry clothes and any other washing you may have - this adds to the amount of water vapour in the air.
  • Homeowners are more likely to keep the windows closed during winter in order to conserve heat. This means that any moisture, which may be produced from cooking, showering, bathing or any other day-to-day activities, will have no means of escape from the house. As a result of this, the moisture in the air will settle onto cooler surfaces.
  • Draught excluders are sometimes introduced to the home in winter as a handy method of keeping out any cold air from outside. Once again, any indoor humidity will be trapped inside the house, meaning that all moisture from the air will automatically form condensation on any surface that is cooler than the surrounding air.

Read our 'what causes damp problems' page to find out whether it's condensation that your home is suffering from. One method of dealing with condensation dampness in the home is through Positive Input Ventilation (PIV). Positive Input Ventilation is a technique designed to filter fresh air throughout your property, which will in turn reduce the amount of humidity and reduce the chances of condensation. So, if you’re looking to reduce the humidity levels in your home and diminish your condensation problems then why not give the experts at EnviroVent a call to arrange a free, no obligation healthy home check.
