Condensation in Apartments: What You Need to Know This Winter

As the colder months arrive and heaters start running, many apartments will see a rise in condensation—that’s when warm indoor air hits cold surfaces like windows and walls, turning moisture into water droplets.

​Why It Matters
While it might seem harmless, condensation can lead to:

• Mould growth
• Damp patches and peeling paint
• Damage to walls and timber
• Health concerns, especially for people with allergies or asthma

How to Reduce It

• Open windows for a few minutes each day
• Use exhaust fans in bathrooms and kitchens
• Avoid drying clothes indoors (or ventilate if you must)
• Keep lids on pots when cooking
• Leave space behind furniture for airflow
• Maintain steady, even heating

Use Your Air Con’s Dry Mode
All air conditioners have a “dry” or dehumidifier mode—great for removing moisture without cooling the room. It’s a simple and effective way to reduce condensation during winter.
