Window Condensation

Many homes experience condensation (sweating windows)  during the winter months.  It occurs when warm, moist air comes into contact with cold surfaces such as windows & condenses into liquid. It is more of a problem now than in the past as our houses are sealed more efficiently, preventing moisture escaping.

It can also occur on other surfaces such as walls and ceilings. Over time, these damp surfaces can provide a perfect environment for mould & mildew to grow.

Every day, several kilos of moisture is generated in our homes via a number of sources. Breathing, washing dishes, showering, cooking, washing clothes, drying clothes in the tumble dryer and indoor heating  are just some common causes.

How to prevent condensation:

There are a number of ways to reduce, or prevent condensation occurring in your home including;

Dehumidifiers - If you have a particular room that is prone to condensation (in my experience, bathrooms and bedrooms are most commonly affected), then use a dehumidifier to remove some moisture from the air. There are a number of products available ranging from containers with crystals which absorb excess moisture to larger electronic dehumidifiers. Humidity in the home should be around 30%.

Exhaust fans - Whenever you are taking a shower or bath or cooking, use an exhaust fan. If you do not have exhaust fans in your home, open the window when cooking and using the bathroom.

Open windows - A simple and effective measure is to open windows for a few minutes on a morning. Sleeping with windows ajar can also be an effective way to prevent, or reduce condensation.

Tumble drying - Tumble dryers are a major cause of increased moisture in the home. Wherever possible, hang washing outside on the line. If you must tumble dry, keep the room well ventilated and make sure the dryer vents outside.

Indoor plants are another cause of condensation. Keep them away from windows. Limit the number of plants you keep indoors.

Containment - When cooking in the kitchen or using the bathroom, try to keep the water vapour contained by closing the door to prevent it spreading.

Heaters - Paraffin and portable gas heaters produce more moisture than other forms of heating, so avoid using them if possible.
