Condensation, Mould and Damp

No one wants damp or mould in their home—especially during colder, wetter months when condensation is more common. Understanding the difference between condensation, which can lead to mould, and damp can help to prevent and treat issues early. 

A warm, well-ventilated home is the best defence, but we know heating costs can be a worry. If you're struggling with energy bills or rent, please contact us —support is available. 

Spotting the Difference 

• Condensation happens when warm, moist air meets a cold surface—like steam on a bathroom mirror. Everyday activities like cooking, boiling a kettle, or showering can cause it, especially in winter when windows stay shut and ventilation is reduced. 
• Small amounts are normal, but if left unmanaged, condensation can lead to mould, which may affect your health.  

What You Can Do 

There are simple steps you can take to reduce it—check out our helpful handy tips guide and video to find out how to spot the signs, prevent build-up, and treat affected areas.
