Does Your Home have a Window Condensation Problem?

By EnviroVent Mar 19, 2021

Although the weather is starting to improve, it is still a little bit too cold to leave your windows open at night, so the chances are that you are still waking up each morning with windows that are covered in condensation and seeing pools of water on your windowsills.

Streaming windows are one of the most common symptoms of a condensation problem that can lead to damp and the growth of unsightly and dangerous mould in your house.

What Causes Condensation

Any activity in your home that releases water vapour into the air contributes to condensation.  Cooking, bathing, and drying clothes indoors are all sources of moisture.  At night, breathing is also a major source of moisture – every time we breathe, we release a small amount of water into the air from our lungs which can build up overnight and lead to streaming windows in the morning.

Condensation is formed when warm, humid air comes into contact with a cold surface such as a window or wall.  The temperature of the air drops and it can no longer carry as much liquid, so that liquid is released and forms droplets of water that eventually form the condensation that you see in the morning.

On surfaces like glass or tiles, the water will stay on the surface where it can easily be wiped away, but condensation forms on every cold surface, and rather than staying on the surface, it can soak in to cause damp, which is a real problem.

Reducing Condensation

There are some good sense steps you can take during the day to reduce the amount of condensation that can form in your home.  Ensuring that you run the extractor fan when taking a shower or cooking and keeping bathroom and kitchen doors closed helps to contain damp air.  Keeping windows open on warmer days also helps as it allows better air flow around your home which reduces the chances of air coming into contact with cold surfaces for long enough for condensation to form. 

However, these steps do not prevent condensation altogether.  In order to tackle condensation properly and to reduce the risk of damp and mould growth, you will need to improve the ventilation in your home.

Simple extractor fans in bathrooms and kitchens are extremely useful in tackling the amount of moisture in those rooms, however they do not run all the time, and do not affect the airflow in other areas of your home.

In order to prevent condensation altogether, you need to consider whole house ventilation such as a Positive Input Ventilation (PIV) system.  These work by drawing air in from outdoors through a central pump and then distributing it around the house.  The fresh air is filtered to remove impurities and gently fed into your rooms to displace the moist air which can settle into condensation.

If you are concerned about the amount of condensation in your home and want to avoid the risk of damp or the health problems caused by the growth of black mould, then you should speak to one of our local specialists.  They can arrange a free home survey to assess the risk and recommend the right actions to take in order to prevent condensation and damp forever.  Contact us today to find out more.
