Draught Proofing Your Home

9 out of 10 homes in Victoria have unwanted draughts and at this time of year they are particularly unwanted.

Draught proofing is finding and fixing draughts to make your home more comfortable and energy efficient. Whilst good ventilation helps reduce condensation and damp and can help cool down a hot house, draughts are uncontrolled – they let too much cold air in and waste too much heat.

Draughts come into your house through gaps and cracks around doors, windows, exhaust fans, fireplaces and so on. To draught-proof your home you will firstly need to find the draughts.

  • Look for obvious gaps 
    Visible light under and around doors and windows is a good clue.

  • Listen for rattles or whistling 
    Take time out, especially during strong winds, to listen for rattles and whistling around doors and windows.

  • Feel for moving air 
    Feel around doors, windows, fireplaces, air outlets, vents, stairways, floorboards, exposed rafters and beams, built-in heaters and air conditioners, architraves and skirting boards.

  • Look for movement in curtains
    Movement in and around curtains can be an indicator of draughts.

The Victorian Energy Saver Incentive Scheme provides support to Victorians who install certain draught-proofing and weather-sealing products.

Warning - Special care needs to be taken in houses that have internal gas appliances, especially houses with:

  • flueless gas heaters

  • a gas heater installed in a chimney

  • an open flued gas heater.

Fixed ventilation openings required for flueless and open flued gas heaters must not be blocked.
