What Causes Condensation?
Condensation is caused by having high levels of moisture laden air inside of a property that cannot escape as a result of poor ventilation and then collides with a cold surface e.g. windows or windowsills. The leading cause of condensation in properties is due to the lack of ventilation inside the house.
A daily routine from an average household of 4 people which includes general everyday activities such as boiling a kettle, having a shower, cooking and just breathing contributes approximately 4 pints of water per person, this gives an overall figure of around 100 pints a week. The damp air must go somewhere.
What causes condensation to form?
Condensation can occur in any type of property but the main cause for condensation is the lack of good ventilation inside of the building. Due to energy savings methods being introduced, such as double glazing and draught proofing, warm moisture laden air becomes trapped on the inside of the property.
The more moisture filled air is trapped inside the property then the more chance that condensation will occur. Windows are where you are most likely to find condensation as this is a cold surface. Having good ventilation to maintain a good airflow in the property is the only true way to get rid of condensation. The main causes for condensation are listed down below:
- Showering and Bathing- if the bathroom is not ventilated then the warm moisture laden air will condense onto the walls which cause for mould growth to occur. Most modern homes are fitted with extractor fans however, if this breaks or becomes faulty then condensation will become a problem.
- Drying and Washing Clothes Inside- Having clothes dried or washed inside of the house this is a common cause for condensation. This usually occurs when home owners dry clothes on radiators so it is best to dry clothes outside whenever possible.
- Cooking- Kitchen areas are a common area for moisture to build up. When meals are prepared it is common for high levels of water vapour to be released into the air (e.g. Steam). Another problem that arises when people are cooking is if the extractor fan is not used correctly which can compound the problem of moisture in the air.
Is Weather a Cause of Condensation?
The weather itself does not cause condensation but condensation is more prominent in colder months of the year than compared to the summer. The reason why this happens is that people tend to have their heating on in the cooler months whilst keeping the windows closed. Once the temperature starts to drop, you will see the telltale water droplets appearing on the surface of the windowsill.
Problems That Can Occur from Condensation
Having moisture on your wall or window may not seem like a big problem as a homeowner, however, if left for some time this can lead to other condensation issues such as black mould growth. Not only does this not look attractive at your property but it can also lead to problems with your health. Health issues such as skin rashes, sinus problems are common especially with vulnerable people such as asthmatics, the young and the elderly.
How do you stop the causes of Condensation?
There are simple measures that can be carried out yourself to help get rid of condensation. By simply opening doors and windows when cooking or bathing the airflow inside of the property can be improved.
By making sure your house is kept at a constant even temperature throughout the day can help ensure that condensation does not start forming on cold surfaces. As mentioned previously, having an extractor fan working properly in the kitchen can also prevent warm moisture laden air from becoming trapped in the property.
