Condensation

---

Condensation forms when warm, moisture-rich air cools and can no longer hold all its water vapor. As the air cools, excess moisture condenses into tiny water droplets on cold surfaces. this is condensation. It’s a natural process but, left unchecked, can lead to bigger issues in the home.

When there’s too much condensation, mould can thrive. Mould often appears on walls, ceilings, windowsills, and hidden spots behind furniture. It can vary in colour—green, yellow, white, or black, and each type can pose different risks, from damaging surfaces to triggering health issues like allergies and respiratory problems.

Condensation and mould are warning signs of underlying moisture issues, and it’s best to enlist a specialist to determine the cause and advise on long-term solutions. Tackling the source of condensation, not just covering it up, is key to preventing these issues from recurring.

The kitchen and bathroom are often blamed, as activities like cooking, showering, and washing release a lot of moisture into the air. While balancing insulation, heating, and ventilation can help reduce moisture build up, condensation shouldn’t normally be a problem in a well-maintained home. Another form of condensation, known as interstitial condensation, happens within the building structure itself, often when materials reach the dew point inside walls, floors, or roofs. This can easily be mistaken for rising or penetrating damp, but addressing it requires a different approach.
