Skip to content Many homeowners encounter condensation on their windows and doors, especially during colder months. Window condensation may seem like a small issue, but it can affect your home’s comfort, energy efficiency, and even its structural integrity. In this guide, we’ll cover what causes window condensation, its different types, and effective solutions. We’ll also explore the difference between window condensation and blown or failed double glazing, with tips on when to consider double glazed glass replacement.
Window condensation occurs when moisture-laden air meets a cool surface, releasing tiny water droplets on the glass. This can happen on the inside, outside, or even between the panes, each indicating a different cause.
Colder outdoor air meets warm indoor air, especially with single-pane or outdated double glazed windows, causing condensation to form on the interior glass.
Poor airflow keeps moisture trapped indoors, often from cooking, showering, or breathing. This trapped moisture raises indoor humidity, leading to condensation.
Rooms with excess moisture—like kitchens, bathrooms, or even laundry rooms—often experience more condensation, particularly in winter.
Recognising the type of condensation can help you choose the right approach
Forms on the inside of windows and doors, often due to high indoor humidity. It’s common in rooms with moisture, especially in winter.
Occurs on the outer side of windows, typically on humid mornings. This type doesn’t indicate a window issue and usually disappears as the temperature rises.
This points to a seal failure, allowing moisture to enter the space between the glass panes. It’s a common issue in older double-glazed windows.
Condensation itself doesn’t pose direct health risks, but it can create conditions that contribute to other issues that may affect health. Excessive condensation on windows or other surfaces can create a damp environment conducive to mold and mildew growth. Mold spores can exacerbate respiratory problems, trigger allergies, and cause other health issues, particularly in individuals with asthma or other respiratory conditions.
According to the NHS website, moulds produce allergens and toxic substances that when inhaled or touched can cause “allergic reaction, such as sneezing, a runny nose, red eyes and skin rash.
“Moulds can also cause asthma attacks.”
While condensation may be temporary or manageable, blown or failed double glazing is a more serious issue that typically calls for professional intervention.
Blown double glazing is like a broken promise, where the seal between the glass panes fails, letting in unwanted moisture and fogging up the view.
The only way to fix blown double glazing is to replace the entire unit.
To effectively reduce or eliminate condensation on windows, you can employ several strategies:
Improve Ventilation:
Use Dehumidifiers:
Monitor Indoor Humidity:
Seal Windows and Doors:
Insulate Windows:
Use Insulating Window Treatments:
Increase Surface Temperature:
Remove Excess Moisture Sources:
By implementing these strategies, you can effectively reduce condensation on windows and create a more comfortable and healthy indoor environment. However, it’s essential to assess your specific situation and needs to determine which combination of methods will be most effective in addressing condensation issues in your home.
