How To Stop Condensation

stop condensation on windows


Condensation on windows is a problem. For many of us, it is an all too common one. In this article, you will learn tips and tricks on how to stop condensation in your homes and windows.

Left untreated condensation can lead to mold growth which can be potentially harmful and lead to serious health issues and breathing difficulties which is why it is important to reduce humidity levels in a property.

The reason condensation appears in your property is due to a lack of ventilation which causes humidity levels to rise and produce moisture on windows and damp areas throughout your home. As we spend more time indoors and make our property more energy efficient the build-up of moisture and humidity levels increase.

Window condensation is usually a bigger issue in colder months. This is because the warm air in your home holds more moisture than cold air. The surface temperature of your windows is also much lower. Together this means more moisture is deposited onto cold surfaces like windows and exterior walls. At Sage Windows and Doors, we receive hundreds of calls from people wanting to know how to stop condensation on their windows in winter.

If you constantly have to wipe condensation off your windows and have a dehumidifier running for lengthy periods of time then you may want to think about whole house ventilation as a permanent solution to condensation and to improve the air quality in your home.

If you are looking for a short term fix rather than a permanent solution then here are our suggestions to reduce the condensation levels in your property:

Tip 1:

Double glazing, loft insulation, and draft proofing will help to reduce the amount of heat that is lost from a property. Installing insulation will help to keep the temperature of the surfaces inside your property at a higher level. Not sure what Double Glazing is?

Tip 2:

Dry your clothes outside, weather permitting, as wet laundry is a well-known source of condensation. If you must dry them indoors, leave the door of the room open, so that the air can circulate freely and prevent condensation forming. You should also leave the windows open a crack, even in winter.

Tip 3: 

Install an extractor fan in your kitchen. You should also make sure, when cooking or boiling a kettle, that the door of the kitchen is kept shut, as far as possible. This will stop the condensation from spreading to other parts of the house.

Tip 4:

When it comes to stopping condensation, there is one method that is often overlooked – temperature. When you heat a room the warm air can hold a greater amount of moisture than cooler air. When the warm air in the room dramatically cools at night, the cooler air cannot hold the same volume of moisture so it is deposited as condensation on cold surfaces like windows and external walls. This is why the most commonly recognisable sign of condensation is streaming windows in the morning and condensation on walls.

Tip 5:

Leave a small gap between your furniture and the walls. This is a trick people often miss because the temptation is to maximise space by having sofas and cupboards flush against the wall. But leaving a gap enables the air to circulate freely. Otherwise, condensation can form at the bottom of the walls with mold resulting in the longer term.
