Stop Your Curtains Getting Damp and Mouldy
It’s time to bid farewell to summer for another year and start facing the reality that soon it’s going to be cold and damp for a while. As we enter those colder months and condensation appears on the windows, we thought it was a good time to share some tips on preventing mould and mildew growing on your curtains.
What makes mould and mildew grow?
Interestingly, it’s not directly the condensation on your windows that causes mould and mildew because most curtains don’t come into contact with it. Mould and mildew grow when there’s moisture and warmth in the home, which condensation does contribute to.
Just like everything absorbent in your home, as temperatures go up the moisture in the air evaporates and is absorbed into the fabric. As they cool, the moisture changes back from its gaseous state to being closer to its liquid form. In absorbing this moisture, they also take in any bacteria it holds. Repeated over time, this is what causes the nasty growths.
The difference between mould and mildew
Mould is a broad term that encompasses multiple identical nuclei and can grow beneath and penetrate the surface of affected material. Mildew is a type of mould that grows on the surface and can therefore be much more easily treated/removed. When its live, moulds are orangey or reddish in colour. The black patches we see are actually the hibernating mould spores waiting for the sun to warm them up and bring them back to life.
Where does all this moisture come from?
We live in a pretty humid climate in New Zealand at the best of times; in some areas it’s even greater. But it’s not all weather related. Cooking, showering, drying clothes, unflued gas heaters and simply breathing and existing all produce moisture content within our homes.
Preventing moisture build up and/or drying out your home
- Install a home ventilation system of some kind.
- Crack the windows a little during the day to allow a bit of cool air to flow through your home. North facing windows are best....

Time to Tickle Your Thinker 🧠
If a zookeeper had 100 pairs of animals in her zoo, and two pairs of babies are born for each one of the original animals, then (sadly) 23 animals don’t survive, how many animals do you have left in total?
