Condensation: Why It Happens and How to Manage It

Condensation occurs when warm, moist air meets cooler surfaces, leading to the formation of water droplets. While it may seem minor at first, persistent condensation can cause a range of problems inside the home and in vehicles such as cars, caravans, and boats. Over time, it can lead to damp patches, mould growth, musty odours, and damage to surfaces, fabrics, and stored belongings. Common problem areas include window sills, kitchens, bathrooms, laundries, wardrobes, storage rooms, and enclosed vehicle interiors where airflow is limited.

Why Condensation Happens

Temperature Differences

When warm, humid air meets cooler surfaces—such as windows, walls, furniture, or vehicle interiors—it cools down and releases moisture in the form of water droplets.

Visible Water Droplets

Condensation often shows up as droplets on windows, mirrors, and cold walls, especially in the mornings or after activities like cooking, showering, or doing laundry.

Poor Ventilation

Lack of airflow traps moist air indoors and inside vehicles, causing humidity to rise and condensation to form.

High Indoor Humidity

Everyday activities, including cooking, showering, washing clothes, and drying laundry indoors, all add moisture to the air, especially in sealed environments like cars and caravans.

Steps to Manage and Prevent Condensation

Taking simple, proactive steps to manage moisture and ventilation can significantly reduce condensation problems, keeping your home and vehicles fresher, drier, and healthier.

Increase Ventilation

Allow fresh air to circulate by opening windows and doors regularly. Use extractor fans in kitchens, bathrooms, and laundries, and ensure vents in vehicles and caravans are unobstructed. Improving ventilation helps release humid air before it turns into condensation.

01

Reduce Moisture Sources

Minimise activities that add excess moisture indoors. Use lids on pots when cooking, vent clothes dryers outside, and dry washing outdoors when possible. In vehicles, avoid storing wet items and wipe down any damp surfaces promptly.

02

Maintain Consistent Temperatures

Keeping a steady, moderate indoor temperature helps reduce cold surfaces where moisture can settle. In homes, consistent heating and insulation help; in vehicles and caravans, using ventilation and occasional heating prevents cold spots that encourage condensation.

03

Use Moisture Absorbers

Moisture absorbers like DampFree can help naturally control humidity when placed on window sills, in wardrobes, cupboards, laundries, kitchens, bathrooms and even vehicles. By drawing excess moisture from the air, moisture absorbers help prevent water droplets forming on windows and other surfaces, protecting against mould, dampness, and odours.
