Understanding Condensation on Windows: Why It Happens & How to Prevent It

Introduction

As the cooler months of autumn & winter set in, many homeowners notice the unwelcome issue of condensation on their windows. While it may seem like a minor inconvenience, persistent condensation can lead to bigger problems, such as damp & mould, if not properly managed. In this advice centre article, we’ll explore why condensation is more common during these colder seasons, offer practical tips to reduce or prevent it, & share some useful information to keep your home cozy & comfortable.

Why Condensation is More Noticeable in Autumn & Winter

Condensation occurs when warm, moist air comes into contact with cooler surfaces, like your windows. During autumn & winter, your home’s interior is typically much warmer than the outside environment, especially with the heating on. The temperature difference between the indoors & outdoors increases the likelihood of condensation forming, particularly on your windows, which are natural cold spots.

In the warmer months, windows are usually left open, & indoor humidity is lower due to better ventilation. However, as we move into the colder months, windows are kept closed more frequently to retain heat, which traps moisture inside. This creates the perfect conditions for condensation to form.

Tips to Prevent or Reduce Condensation

While condensation is a common issue, there are several practical steps you can take to reduce or prevent it from affecting your home:

1. Improve Ventilation

Good ventilation is key to reducing indoor humidity. Regularly opening windows, even for just 10 to 15 minutes a day, can allow moisture to escape & fresh air to circulate. For rooms that produce a lot of moisture, such as kitchens & bathrooms, ensure extractor fans are used while cooking or showering.

2. Use a Dehumidifier

If ventilation alone isn’t sufficient, a dehumidifier can help to remove excess moisture from the air. This is especially useful in rooms prone to condensation or during particularly damp & cold weather.

3. Install Double or Triple Glazing

Energy efficient windows, like double or triple glazing, can help to reduce the temperature difference between your windows & the air inside your home. This lowers the likelihood of condensation forming. At Pendragon Home Improvement, we only offer A & A+ BFRC Energy rated windows, designed to reduce energy loss & keep your home warmer.

4. Control Indoor Humidity Levels

Activities such as drying clothes indoors, cooking without lids on pans & even showering contribute to higher indoor humidity. Wherever possible, dry clothes outside, use lids while cooking & keep internal doors closed to prevent moist air from spreading throughout the house.

5. Install Trickle Vents

Modern replacement upvc windows come with built-in trickle vents that allow a small amount of air to flow, even when the windows are closed. This helps maintain a consistent airflow without compromising on warmth. For homes with older windows, upgrading to new units with this feature can be a practical solution.

What If You Already Have Condensation?

If condensation has already formed, it’s essential to deal with it promptly. Wipe down windows & cills to remove excess moisture & prevent mould from forming. You can also use products such as moisture absorbers, which are particularly effective in smaller rooms or areas like conservatories & are readily available in supermarkets & pound shops.
