Tackling Damp Homes in NZ - Simple Steps for a Warmer, Drier Home
Many damp problems aren’t caused by the house itself—but by how we live in it. With a few small habit changes and regular checks, you can keep your home warm, dry, and healthy, even through a wet Kiwi winter.
1. Everyday Habits That Help
Open windows for 15–30 mins daily, even in winter.
Open curtains during the day to let sunlight in—sunlight helps warm and dry your home naturally.
Use extractor fans when cooking or showering. Leave them on for 15 mins after.
Avoid unflued gas heaters—they release moisture into the air.
Use a dehumidifier, especially in bedrooms and living areas.
Dry clothes outside or use a vented dryer. If drying indoors, open a window and use a fan or dehumidifier.
Keep a consistent temperature (18–20°C in living areas, 16°C in bedrooms).
2. Stop Condensation Before It Becomes Mould
Wipe down windows each morning in colder months using a microfiber cloth or squeegee.
Clean small mould spots with a vinegar and water mix (3:1). Bleach doesn’t kill mould.
Leave space behind furniture and open wardrobe doors regularly to avoid trapped moisture.
3. Quick Annual Maintenance Checklist
Clear gutters and downpipes
Check roof for leaks
Look behind furniture for mould
Service heat pumps or heaters
Wash curtains and clean window frames
Make sure vents (window & wall) are open and clear
Check that external drains are not blocked
Final Note
It’s often not just the house—it’s the habits.
Ventilation, sunlight, heating, and how you manage moisture each day make a huge difference. Tackle the damp, and your home will be healthier and more comfortable year-round.
That said, some homes do have underlying issues—like poor drainage, leaks, or structural design flaws.
If you’re doing all the right things and still battling constant damp or mould, it’s worth getting a professional inspection.
A building expert can help identify problems that aren’t always visible and offer practical solutions.
