Mould on your window frame? Here’s why you need to take action.
Mould on window frames is more than just unsightly — it’s often a sign that moisture is accumulating around the glass due to problems with the window itself. Common causes include condensation forming between panes, gaps around the frame, or seals that are no longer effective. These issues allow water to collect in hidden areas, creating the perfect environment for mould to grow.
This isn’t just a cosmetic problem. Mould releases spores into the air, which can trigger allergies, respiratory irritation, and exacerbate asthma or other breathing conditions. Left untreated, it can spread along the frame, onto surrounding surfaces, and even weaken the integrity of the window over time.
Simply cleaning the visible mould won’t fix the root cause — the underlying window problem needs professional attention. Repairs may involve resealing panes, correcting alignment, or replacing compromised glass to stop moisture from accumulating and prevent mould from returning.
