Condensation can be a problem in both old and new homes, but what causes it and what can be done to prevent it?

What is Condensation?

The air around us naturally contains moisture. The air temperature determines how much moisture it can hold, and warm air contains more moisture than cold air.

When moist warm air comes into contact with either air or a surface which is colder than it is, the warm air cannot retain the same amount of moisture as it did and the water is released either onto the colder surface or into the air, resulting in condensation. This then leads to mould formation

What Causes Condensation?

Everyday activities such as washing cooking, drying clothes and even breathing produce excess moisture. Air can only hold so much moisture, so when it contains too much moisture it reaches ‘saturation point’.  This is when the moisture turns back into water and condensation occurs.

How Can I Treat Condensation?

Ventilation

In order to prevent condensation there are three main areas to look at. Ventilation, Insulation and humidity

You can control the humidity levels in your home and in particular in your kitchen and bathroom through use of an extractor fan. Keeping the doors to these rooms shut while the extractor fan is on also helps.

Ensure there is adequate ventilation throughout your home. Newly built properties tend to be airtight which can encourage condensation, so it is vital to ensure that there are vents installed within your home. Learn more about ventilation and the associated services we provide here
