Moisture in your home can have serious problems for both your health and your home. High moisture levels can lead to the growth of mould which results in a damp and unhealthy conditions for you and your family. Not only is it unhealthy, but it also makes heating your home less efficient, as damp air takes more energy to heat than dry air.

Do you know the signs that you have moisture in your home?

  • Do you see mould or mildew on your walls, ceilings or around your windows?

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.

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.
