The winter months are not short of wet weather and colder temperatures causing problems for homes and apartments; however the matter of condensation can often be mistaken for a leak and thankfully is largely preventable.

We often receive enquiries regarding condensation in apartments, particularly beneath windows. We have investigated several concerns and find that occupants do not always have working knowledge on how to minimise condensation build-up in their home. Condensation if not managed, can also lead to the formation of mould underneath carpets.

Some of the causes for condensation can include:

  • Cooler outside temperature than inside
  • Modern apartments are well sealed to comply with the Building Code of Australia, in an effort to reduce reliance on additional heating / cooling and thus reducing natural airflow
  • Not utilising vents, extraction fans and windows when required e.g. when showering, running a clothes dryer, or cooking

Living in apartments requires adaptation and use of the tools provided to assist in management of condensation, i.e. fans, dehumidifiers and appropriate ventilation. Larger dwellings such as houses tend to experience fewer condensation problems because of their size and external doors and windows are being opened frequently so moisture in the air gets moved around effectively. The smaller volume of ventilation in a well-sealed apartment is less able to tolerate excessive moisture in the air before it starts to condense on cool surfaces, and before you know it, mould begins to grow.

Here are some simple steps that can be employed by occupants to minimise the build-up of moisture inside the apartment::

  • Close the bathroom door whilst showering – this allows the extraction fan to do its job more efficiently
  • Run the bathroom and kitchen exhaust fans for a period of time after showering or cooking
  • Open a window slightly when showering or cooking
  • Open external doors and windows for a good period each day to allow natural ventilation to allow moisture to escape
  • Hang drying clothes near an open window or door
  • Most apartments have a dehumidifier function in the air conditioner which should be used as a way of reducing moisture – see the instructions for use.

With a little proactive management in ensuring your apartment remains well ventilated with regular opportunities for air exchange, you can minimise the effects of mould and condensation in your home.
