What causes moisture in your home?
General day-to-day living
Everything from cooking and taking a shower to simply breathing creates moisture within your home. Although on their own it’s not a huge amount of moisture, it can all add up. Cooking alone can release as much as three litres of moisture into the air, every day!
Drying Clothes
Throughout winter, we tend to hang our clothes indoors to keep on top of the washing. But, this can add an extra 5L of moisture, per load!
Leaks
Leaks in your roof, plumbing, or other areas of your home can lead to moisture build-up and mould growth.
Poor Ventilation
Poor ventilation will quickly lead to moisture buildup in your home, especially in areas like your bathroom and kitchen when a lot of heat and steam are created.

Preventing moisture in your home will help keep your home healthy
Taking the time to tackle the issue of moisture in your home can make a huge difference to how your home environment feels to be in, and it will help keep you and your family healthy too.
- Fix any leaks
- Dry clothes outdoors whenever possible
- Use a dehumidifier, or the dry function on your heat pump, to help reduce humidity levels in your home and prevent moisture build-up.
- Open windows to naturally air your home and bring in fresh air.
- Ensure you have extractor fans in kitchens and bathrooms making sure these are on, or your window is open when you are showering, taking a bath and use pot lids and range hoods when cooking.
