Keeping Your Home Warm and Dry This Winter

A warm home is important, but a dry home is just as important.

Many New Zealand homes struggle with dampness during winter. Condensation on windows, musty smells, and mould growth are all signs that excess moisture may be affecting your home.

A damp home often feels colder than a dry one, meaning you may use more electricity trying to stay comfortable.

Why Moisture Matters

Everyday activities create moisture inside the home. Cooking, showering, drying clothes, and even breathing release water vapour into the air.

When that moisture has nowhere to go, it settles on cold surfaces such as windows and walls.

Over time this can lead to:

• Mould growth

• Damage to furnishings

• Increased heating costs

• Poor indoor air quality

Simple Ways to Reduce Dampness:

• Ventilate Daily

Opening windows for a short period each day helps remove stale, moist air and allows fresh air to circulate.

• Use Extractor Fans

Run extractor fans when cooking or showering and leave them running for a few minutes afterwards.

• Dry Clothes Carefully

If possible, dry clothes outside. If you need to dry them indoors, choose a well-ventilated room and consider using a dehumidifier.

• Heat Your Home Consistently

A warm home is less likely to develop condensation than a cold one. Even a modest amount of heating can help keep moisture levels under control.

A Healthier Home

Reducing dampness can make your home feel warmer, improve air quality, and help prevent mould growth. Small changes can make a noticeable difference to comfort throughout winter.
