By EnviroVent

Most of us have experienced condensation in our property at some point in time, most likely during the deep winter months. In fact, one in five UK homes suffer from it. The cold weather brings our attention to damp problems hiding in our homes, resulting in streaming windows and all number of debilitating problems, including damp and mould. The problem will come back to haunt you time and time again unless it is dealt with professionally. If you think you might have a condensation issue in your home, keep reading for everything you need to know about how to treat and prevent it.

What is condensation?

Condensation occurs when warm, moist air comes into contact with a surface of a lower temperature (or air of a lower temperature). When the two different temperatures clash, the warm air loses its ability to hold moisture. This results in water vapour suspended in the air and the appearance of water on the surface.

What are the most common causes of condensation?

Culprits include common everyday activities like cooking, drying clothes on radiators and washing up. You can also help keep condensation at bay by heating your home on low all day during periods of cold weather.

Where does condensation form?

Condensation forms on any surface, but is easier to detect on non-absorbent surfaces like windows and bathroom tiles. Other common signs of visible condensation include water, frost or ice on doors, frames and ceilings. But condensation can also be absorbed by household items and soft furnishings. If your bedroom windows are covered in condensation every morning, your upholstery, bed covers and clothes probably are too!

Why does condensation appear in my property?

The short answer is inadequate ventilation. Think about this: the average person breathes in and out around 17,000 times per day. If your home is sealed up, you can only imagine what kinds of pollutants fester in the air. Condensation affects all types of properties including new builds, period properties and bungalows.

Why is condensation worse during winter?

We spend lots more time indoors during the winter months. Most of us use more energy on daily activities like using the tumble dryer or boiling the kettle at this time of year too, so moisture and humidity levels increase.

What problems can condensation cause me and my family?

Homeowners and occupants can experience all number of health problems and ailments as a result of breathing in water vapour. Because of their weak immune systems, babies and elderly people are of particular cause for concern, as are people with allergies or existing respiratory problems like asthma.

What damage can condensation do to my property?

Condensation can cause a number of issues to your home if left untreated over a long period of time. Damp patches on the walls, peeling wallpaper and black mould on the ceiling are all strong indicators of a serious condensation issue.

How do I treat and prevent condensation?

The best way to keep condensation at bay is to make sure your home is adequately ventilated. This can mean ventilating excess moisture to the outside of your property and circulating your home with fresh air. That doesn't mean you have to sit there with the windows wide open in the midst of winter!
