What Causes Condensation?

Wondering what might cause condensation in a property?

Condensation is simply the product of having high levels of dense, moist air within a property that can’t circulate outside. When this dense air becomes trapped it’s going to come into contact with cooler surfaces such as your walls, windows, countertops and so on. On contact with these surfaces, the dense air reverts from its gaseous state to a liquid one. This is how condensation is formed.

The leading cause of condensation is primarily a lack of ventilation, though other factors do influence the amount of condensation greatly.

For example, a daily routine in an average household containing four people will include daily activities like boiling the kettle, having a shower (or a bath), cooking, and exercise. All of these activities add up, and on average it amounts to about four pints of water produced per person in the form of hot, moisture rich air.

Over a week that all adds up to around 100 pints of water a week – and all of that damp air has to go somewhere.

What Causes Condensation to Form?

Condensation can occur in any type of property, but the main cause of condensation is a lack of decent ventilation throughout the inside of the building. Energy saving measures haven’t helped he onset of condensation either, with double glazing and draught proofing trapping more warm, moisture-laden air inside than ever.

The more moisture-filled air that’s trapped inside your property, the higher the chance that condensation is going to occur.

You will most likely find condensation on exterior facing walls and windows. That’s because the warmer air inside your property is attracted towards the cooler air outside your property due to the disparity in air pressure. Making sure good ventilation is in place around these at risk areas is going to do a great deal in helping reduce the overall level of moisture building up on your walls and windows.

What then, are the primary causes of condensation being created?

  • Showering and Bathing: If your bathroom is not ventilated then the warm, moisture-laden air is going to condense onto the walls and windows, creating the ideal conditions in which black mould can grow. Most modern homes are fitted with extractor fans, however, if this fan breaks or becomes faulty then condensation can quickly become a problem.
  • Washing and Drying Clothes Inside: Washing your clothes and then drying them inside is an incredibly common cause of condensation. The main culprit of condensation creation here is usually when home owners dry clothes on their radiators, without allowing for the ventilation needed to carry away all of the moisture evaporating off of the clothes.
  • Cooking: Kitchens are rife with condensation because of the heat created when cooking. Think about the amount of water vapour created when cooking, or boiling the kettle. The amount of steam created in the kitchen is quite high, and is pretty common as well. Always make sure to use the extractor fan on your cooker if its available, because if its left ignored or broken then you can compound the problem of moisture in the air.dry clothes on radiator

Is Weather a Cause of Condensation?

No, the weather on its own is not a cause of condensation. However, when the temperature is colder outside you are going to see a higher amount of condensation because of the heating being used inside properties, and that is going to create more moist air, and as a result, more condensation on your walls.

Problems That Condensation can Cause

Having condensation droplets on your walls and windows might not seem like that big of a problem, but as a homeowner (or property owner), you should be aware that this is just the first step leading to a number of different problems.

You can encounter condensation based damp, as well as black mould growth. Black mould is especially nasty as it won’t just ruin your wallpaper or plaster, but it can also have a real, negative affect on your physical health. It may cause rashes, exacerbate sinus problems, cause or worsen asthma, or even trigger allergic reactions. These are particularly likely amongst the young, elderly, and those at risk from medical troubles.

How do you Stop the Causes of Condensation?

You can put a stop to the causes of condensation very simply, helping you get rid of your condensation problem quickly and easily. For example, by opening your doors and windows you can create an easy airflow that will help to increase the level of ventilation in your property. Doing this when you are coking, cleaning, bathing, or doing the washing can drastically reduce the amount of condensation being created.

Making sure that your property remains at a consistent temperature is also a great way to help reduce the risk of condensation forming on cold surfaces. Using appliances like extractor fans, or trickle vents in addition to cimlate control is only going to escrease the likelihood of condensation and its associated problems setting in.

Need Further Advice On Condensation?

Condensation can be a problem for any homeowner, and if it’s not rectified quickly it can become a real serious issue.
