How to Prevent Mould Around Windows?

Mould around windows is a common problem in many Australian homes, especially in humid climates like Queensland and New South Wales. Left untreated, mould can damage window frames, stain walls, and even affect your family’s health. The good news is that with a few smart steps — including choosing the right window coverings like DIY plantation shutters — you can prevent mould from becoming an issue.

Why Does Mould Form Around Windows?

Mould thrives in damp, poorly ventilated areas. Windows often collect condensation, particularly in cooler months when warm indoor air meets cold glass. This moisture provides the perfect environment for mould to grow.

Common causes include:

Poor air circulation
High indoor humidity levels
Inadequate insulation
Condensation build-up on glass panes

Practical Ways to Prevent Mould

1. Improve Ventilation

Open your windows regularly to let fresh air flow through. Using exhaust fans in kitchens and bathrooms can also help reduce indoor humidity.

2. Manage Condensation

Wipe down windowsills and glass daily if condensation forms. You can also use a dehumidifier to reduce moisture levels indoors.

3. Insulate Your Windows

Well-insulated windows help minimise temperature differences that cause condensation.

4. Choose the Right Window Coverings

Curtains and blinds often trap moisture against the glass, creating the perfect environment for mould. In contrast, plantation shutters allow airflow and reduce dampness while still giving you privacy and light control. Opting for DIY shutters not only keeps costs down but also provides a mould-resistant upgrade to your home.

5. Regular Cleaning

Use a gentle cleaning solution (like white vinegar and water) to wipe down your windows and frames. This prevents mould spores from settling and spreading.

Long-Term Benefits of Preventing Mould

By keeping mould away from your windows, you’ll:

Improve indoor air quality
Protect your family’s health
Extend the lifespan of your window frames and shutters
Keep your home looking fresh and well-maintained
