Understanding Condensation in your Home

Condensation is completely normal and happens inside everyone’s home, particularly as we all try to improve building efficiency and EPC ratings, reduce draughts and save money on heating bills. 

Condensation occurs when moist air hits a cold surface. This commonly happens in kitchen and bathrooms, where there is a lot of moisture. Look out for condensation in corners, near windows, and other areas with little air flow.

A modern house with warmer air will generally see less condensation, however modern homes are often airtight and it is important that mechanical ventilation equipment built into the home is used to reduce build-up of condensation.

Problems occur when too much moisture collects, and if left, can cause black mould to form on walls, window frames, carpets and soft furnishing. Too much condensation can cause mould to grow in areas where water droplets have been left.

Mould can give an unpleasant smell and in severe cases can pose a significant health risk to those with respiratory problems, such as asthma.

• Adequate ventilation will help manage levels of condensation in your home. Keep trickle vents open and when possible, open your windows.
• Dry windowsills and window frames, especially during cooler months to remove excess moisture.
• Use your extractor fan when showering, bathing or cooking, reporting any instances when these are not working to Radius.
• Never block or conceal any vents or extractor fans in your property.
• Keep lids on pans when cooking.
• If drying clothes inside, keep the door of the room closed and use an extractor fan or dehumidifier if possible.
• If you use a tumble dryer ensure it is appropriately ventilated. If not, this will contribute to condensation in your home.
