How to Prevent Mould in a Built-In Wardrobe

Introduction: Don’t Let Mould Ruin Your Fitted Storage

A built-in wardrobe adds elegance and functionality—but without proper precautions, it can become a breeding ground for mould, especially in humid or poorly ventilated homes.

In this guide, you’ll learn practical, effective ways to keep mould from developing inside or behind your built-in wardrobes—and maintain a fresh, dry environment for your clothes and belongings.

Why Does Mould Form in Built-In Wardrobes?

Mould is caused by excess moisture and poor airflow. Built-in wardrobes, especially those placed on external or poorly insulated walls, are vulnerable because:

• Air circulation is limited behind panels
• Wall condensation can occur in colder months
• Items stored inside may block airflow

💡 Pro Insight: Mould usually starts invisibly on the back wall or baseboard—routine checks are essential.

7 Ways to Prevent Mould in Built-In Wardrobes

1. Allow Airflow Behind Panels

When installing a built-in wardrobe, leave a 20–30mm gap between the unit and external walls. This helps prevent trapped moisture from building up.

2. Use Ventilation Grilles

Install discreet wardrobe vents on the top or sides of the doors to allow airflow inside the unit—even when closed.

3. Add a Dehumidifier

Use a small plug-in or rechargeable wardrobe dehumidifier—especially in older homes or humid environments.

4. Don’t Overpack

Clothes packed too tightly reduce circulation. Leave gaps between items and avoid storing damp clothing.

5. Choose Moisture-Resistant Materials

Ask your supplier to use moisture-resistant MDF or treated boards for rear panels and base plinths.

6. Keep Doors Open Periodically

Opening wardrobe doors for just 15–30 minutes a day allows fresh air to circulate inside.

7. Inspect Exterior Walls

If the wardrobe is built along an outside wall, check for leaks or rising damp. Consider insulating behind the unit if necessary.
