Draught Proofing Services

Preventing cold air from entering your
home in winter and hot air in summer.

Up to 25% of heat loss from existing homes is caused by draughts.

Draught proofing identifies potential areas for air leakage and blocks them to make your home more comfortable and energy efficient.

Draughts are similar to ventilation, in that both let fresh air into your home. Good ventilation helps reduce condensation and damp and can help cool down a hot house. Draughts, on the other hand, are uncontrolled – they let too much cold air in and waste too much heat.

Draught proofing stops warm air from escaping your home in winter and hot air from entering in summer, saving you money and making your home more comfortable.

When assessing your home’s insulation requirements, we can review draught issues, pinpoint problem areas, and install custom draught-proofing solutions around your home that will prevent unwanted hot and cold air from getting in.


The temperature of a heated room in winter should be between 18-21°C.
The temperature of a cooled room in summer should be between 23–26°C.

Did you know it is actually cheaper to keep heating running on low, rather than turning it off and then cranking it up to heat a cold room?

To maximise savings even further…

Curtains, blinds and shutters act as a barrier to the transfer of heat and cold through your windows, especially if you don’t have double glazing. On sunny winter days, open your window coverings to let that energy in to warm up your home for free!

Cleaning and replacing filters on air-conditioners and split systems allows your unit to work more efficiently and can also lower your energy consumption.


Where do draughts enter my home?

Through many places in your home; through cracks, poorly sealed areas around windows and door frames, exhaust fans, fireplaces and chimneys and the big one, floorboards.

How do I identify unwanted draughts?

Look for obvious gaps, visible light under and around doors is a good clue.

Listen for rattles and whistling particularly during strong winds.

If your curtains are moving this is also a good indicator of a breeze coming from somewhere.

Where is draught proofing installed?

To window and door frames, the bottom of doors, exhaust fans and fireplaces.

I have gas appliances, is that an issue?

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.

All flueless gas appliances require a certain amount of fixed ventilation to expel the products of combustion from the home and operate safely. Open flued gas heaters – which draw combustion air from the room in which they are located – require a supply of fresh room air to operate safely.
