Key points about keeping your home warm and dry

  • create as much space to spread out around your home, rather than having to crowd in the same room
  • having more warm rooms and more sleeping spaces available means germs such as strep throat, which can lead to rheumatic fever, are less likely to spread
  • if you choose to follow even just a couple of tips, your home could be cheaper to heat and more comfortable to live in
  • a warm dry home can help to protect your whānau from health problems

How can I make my home warm and dry?


Tamariki (children) cough and sneeze out germs when they sleep so create as much space as possible between each person to make it harder for the germs to spread. 

If they share a room, place their beds on opposite sides of the room. If they are in bunk beds, it is a good idea to have one child’s head at one end and the other child’s head at the other end.

Open your curtains during the day to allow the sun to heat your home. But remember to close them just before sunset to keep the cold night air out.  

If you choose to use sheets or lavalava instead of curtains, make sure you have a snug fit around the window frame. You might be able to get curtains free or cheaply from your local curtain bank.

Heat pumps are ideal as they heat a large area and don't cost as much as other types of heaters. Electrical heaters are also good. Avoid portable gas heaters as they are expensive to run, create dampness and give out dangerous fumes. 

A heater with a thermostat will help control the temperature in your home and keep the cost down. Aim for 20 degrees as  a good temperature when people in your house are up Turn it down to 16 in the bedrooms at night.

Condensation, or water that has collected on windows and walls, makes rooms feel damp. It can also cause mould to grow. To help keep your home dry, wipe it off when you see it. A dry home is easier and cheaper to heat.

Open your windows for at least 20 minutes on fine days and a few minutes daily in winter. Bringing fresh air into your home is another great way to help keep your home dry.

To help prevent dampness and mould, open windows in the kitchen when you cook and in the bathroom when you take a shower or bath. This will help let steam out. Make sure you use your kitchen and bathroom extractor fans if you have them.

To stop cold air getting into your home, stop draughts around doors, windows and fireplaces.  

If you don't have a draught stopper, you can roll up a dry towel and place it there to stop the draught from coming in. You can also buy weather stripping from hardware stores to stop draughts around windows.

Mould grows in damp and wet places and can affect your family's health. 

Bleach or white vinegar will remove mould from ceilings and walls. 

If using bleach, add 2 teaspoons to 1 litre of water.

If using white vinegar, don't add any water. 

Never mix bleach and vinegar.

To help keep the damp out of your home, dry your washing outside, or in the garage or carport.
