What is condensation? Condensation happens when warm, moist air meets a cold surface, such as a window or wall. The air condenses and runs down the surface as water droplets. Condensation is more of a problem in winter than in spring or summer, as the surfaces are often cooler, and the home is less likely to have windows and doors open for long periods. We all get condensation on our windows occasionally, but this isn't necessarily a problem if it clears up quickly.

What steps can I take to prevent condensation in my home?

• Reduce the moisture you create, try keeping lids on pans and avoid drying clothes indoors. Condensation will increase substantially when drying clothes inside, even when using a condensing tumble dryer.
• Increase ventilation: Always use extractor fans in the kitchen and bathroom and allow them to run for about 15 minutes after you leave the room. Avoid blocking wall vents and keep window vents open at all times.
• Try to maintain a constant temperature. If you have rooms where the heating is turned off during winter, you may find that they are prone to damp problems. In this case, you may need to ventilate more or turn the heating on. Aim to keep the property's temperature at 18 degrees Celsius, even in rooms that are not used regularly.

When does condensation become a problem? When should I seek help?

If condensation builds up and you don't wipe it away, it can lead to black spot mould. The first signs of this may be wallpaper peeling off walls or mould growing in unventilated areas such as behind the sofa. At this point, it's best to give us a call so that we can investigate.
