We will guide you through the causes of condensation on glass and provide practical, expert solutions to manage and prevent it. Whether you’re dealing with foggy windows at home or in a commercial space, this comprehensive overview will equip you with the knowledge to maintain clarity and preserve the condition of your windows.
What Causes Condensation?
Condensation occurs when warm, moist air comes into contact with a cold surface, causing the moisture in the air to cool and turn into liquid. This is a common phenomenon in households, especially during colder months when there is a greater temperature difference between the inside and outside of the home.
This is a natural process, but frequent condensation inside homes and buildings can lead to significant issues, such as damp, mould growth, and structural damage.
Why Do I Get Condensation on My Windows?
Condensation forms when warm, moist air meets a cooler surface, such as your windowpane, causing the moisture in the air to condense into water droplets. Several factors contribute to this phenomenon, including:
Poor Ventilation
Insufficient airflow within a property is one of the leading causes of condensation. When the air cannot circulate properly, excess humidity tends to accumulate, which then settles on colder surfaces like windows.
Indoor Activities That Increase Humidity
Everyday activities such as cooking, showering, or drying laundry indoors release a significant amount of moisture into the air. Without appropriate ventilation systems or dehumidifiers, this moisture has no escape route, leading to condensation.
Inefficient Insulation Around Windows
Windows with poor or inefficient insulation may have colder surfaces, making them more prone to condensation. Single-glazed windows, in particular, tend to attract more condensation compared to double- or triple-glazed units designed to maintain consistent surface temperatures.
Condensation on Single-Glazed Windows
Condensation on single-glazed windows is a common concern for many property owners, particularly in older buildings. While it might seem like a minor inconvenience, repeated condensation buildup can contribute to issues such as mould growth, damage to window frames, and reduced energy efficiency within a home or commercial space.
Single-glazed windows are more prone to condensation as they lack the insulating layer present in modern double or triple-glazed windows. This means the inner surface can easily reach a colder temperature, encouraging condensation formation.
Condensation Because of Increased Humidity
High humidity within the home is often a result of everyday activities. Tasks such as cooking, bathing, or drying clothes indoors release significant amounts of moisture into the air. Without adequate ventilation or effective dehumidification systems in place, this moisture accumulates, leading to condensation.
Condensation typically appears on cold surfaces such as windows, walls, and mirrors when warm, humid air comes into contact with cooler temperatures. Over time, this constant moisture can cause surfaces to develop issues such as mould growth, peeling paint, or damage to furniture.
Common Causes of High Indoor Humidity:
- Cooking: The steam produced during boiling, frying, or simmering increases the humidity levels in the kitchen.
- Bathing or Showering: Hot water usage releases a significant amount of water vapour into the bathroom environment.
- Clothes Drying Indoors: Hanging damp clothes indoors is a common but major contributor to moisture buildup in living spaces.
If not addressed, prolonged condensation can promote an unhealthy indoor environment and cause structural issues. Implementing solutions such as extractor fans, proper ventilation, and the use of dehumidifiers can significantly reduce indoor humidity and mitigate condensation problems.
Condensation on New Windows or Between Double-Glazed Panes
When condensation forms between the panes of a double-glazed window, it indicates a failure in the sealed unit. Double-glazed windows are designed with a sealed cavity between the panes, usually filled with gas, to create an insulating barrier. If this seal is compromised, moisture can infiltrate the space. This not only reduces the window’s insulating properties but also affects its overall energy efficiency and clarity.
A failed sealed unit typically requires professional intervention, as replacing the sealed unit is often the most effective solution. It’s crucial to address this issue promptly to restore thermal performance and prevent further deterioration.
Condensation on New Windows
For newly installed windows, condensation is more commonly observed on the interior or exterior surfaces rather than between the panes. This phenomenon occurs because modern windows are designed with highly effective airtight seals, which can trap moisture within the property.
- Interior Condensation: This is usually the result of higher humidity levels inside the home. Everyday activities such as cooking, showering, or drying clothes can release moisture into the air. Without adequate ventilation, this moisture accumulates and condenses on the cooler surface of the window.
- Exterior Condensation: This is often a sign of the window’s high energy efficiency. The exterior pane remains cool as it prevents heat transfer from the inside, causing moisture in the outside air to condense on the glass.
How Condensation Damages Windows
Condensation on windows is a common issue faced by many homeowners, but its impact goes far beyond an inconvenient fog or streaks on the glass. If left unmanaged, condensation can cause significant damage to your windows, compromising both their functionality and aesthetic appeal. From warping wooden frames to encouraging the growth of mould and mildew, the consequences can be costly and harmful.
Understanding how condensation forms and the ways it affects different types of windows is crucial in protecting your home. Persistent condensation can lead to several issues with your windows, including:
- Wooden frames rotting and weakening due to water exposure
- Peeling paint or varnish on window frames
- Damage to seals, reducing the efficiency of double glazing
Which Windows Are Most Exposed to Condensation?
Typically, the windows most exposed to condensation are those that face north or east, as they receive less direct sunlight and thus remain cooler throughout the day.
Additionally, single-glazed windows are particularly susceptible to condensation due to their lack of thermal insulation. In contrast, double-glazed or triple-glazed windows provide better insulation and help reduce the likelihood of condensation forming. However, even energy-efficient windows can experience condensation if there’s a significant temperature difference between the inside and outside.
Areas with high humidity levels—such as kitchens and bathrooms—are also prime locations for condensation build-up around window frames. To combat this issue effectively, homeowners should consider both ventilation and window treatments that allow for airflow while minimising moisture retention.
Single-glazed, old, or poorly insulated windows are most at risk. Windows in rooms with insufficient ventilation, such as bathrooms and kitchens, are also particularly prone to condensation.
Why Do I Get Mould and Damp?
One of the primary causes of mould and damp is poor ventilation. Inadequate airflow in your home can trap moisture, creating an environment where mould thrives. This is particularly prevalent in areas like bathrooms and kitchens, where steam from showers or cooking can lead to condensation on walls and surfaces.
Another significant factor is the presence of leaks or water ingress. Whether from a faulty roof, broken pipes, or rising damp from the ground, any source of excess moisture can provide a breeding ground for mould spores. It’s essential to regularly inspect your property for signs of water damage.
Additionally, lifestyle choices can contribute to mould growth. Activities such as drying clothes indoors without proper ventilation or not using extractor fans can increase humidity levels in your home. By making small adjustments—like ensuring proper airflow and addressing leaks promptly—you can significantly reduce the risk of mould and damp taking hold.

How Does an Air Dehumidifier Work?
At its core, an air dehumidifier operates by drawing in humid air from the surrounding space.
Once the moist air enters the unit, it passes over cooled coils that condense the water vapour into liquid form. This process not only removes excess humidity but also cools the air slightly before it is released back into the room. The collected water is then stored in a reservoir or expelled through a drainage hose, ensuring that your living space remains dry and comfortable.
The effectiveness of an air dehumidifier can significantly improve indoor air quality, reducing allergens like mould and dust mites that thrive in damp conditions.
Does an Open Window Help with Condensation?
The answer is a resounding yes—an open window can indeed help mitigate condensation, but it’s essential to understand the underlying principles at play.
Condensation occurs when warm, moist air comes into contact with cold surfaces, leading to water droplets forming on windows and walls. By opening a window, you allow fresh air to circulate throughout your home, effectively reducing humidity levels. This influx of drier air replaces the moist air that contributes to condensation buildup.
Proper ventilation is crucial for maintaining a healthy indoor environment. Stagnant air can exacerbate moisture issues and lead to mould growth if not adequately addressed. Therefore, regularly opening windows—even for just a short period—can significantly improve airflow and help keep humidity in check.
How Long Does a Dehumidifier Dry Out a Room?
The answer can vary significantly based on several factors, including the size of the room, the humidity levels, and the capacity of the dehumidifier itself.
Typically, a standard dehumidifier can remove approximately 10 pints of moisture per day for smaller units and up to 70 pints or more for larger models. In a moderately humid environment, you can expect a dehumidifier to noticeably reduce humidity levels within just a few hours. However, achieving optimal dryness may take anywhere from 24 to 48 hours.
For effective results, it’s crucial to choose a dehumidifier that matches your specific needs. For instance, in larger spaces or rooms with severe dampness issues—such as basements—investing in a more powerful unit will expedite the drying process. Additionally, keeping doors and windows closed while operating your dehumidifier allows it to work more efficiently by preventing outside moisture from entering.
While there isn’t a one-size-fits-all answer to how long it takes for a dehumidifier to dry out a room, understanding these variables will help you set realistic expectations and make an informed choice when selecting your unit.
What is an Acceptable Humidity Level for Your House?
Ideally, the relative humidity should be kept between 30% and 50%. This range not only ensures a pleasant living environment but also helps prevent issues such as mould growth, dust mites, and respiratory problems.
Excessive humidity can lead to condensation on walls and windows, creating the perfect breeding ground for mould spores. Conversely, low humidity levels can cause dry skin, irritated sinuses, and static electricity. To achieve that ideal balance, consider investing in a hygrometer to monitor your home’s humidity levels accurately.
Why Does Mould Keep Coming Back?
One of the primary reasons mould reappears is the presence of excess moisture in your home. This can stem from various sources, such as leaks, poor ventilation, or high humidity levels. If these underlying issues are not addressed, mould will continue to thrive.
Another factor contributing to recurring mould growth is inadequate cleaning. While surface cleaning may remove visible mould, it often fails to eliminate spores and roots that can lie dormant within walls or hidden corners. To combat this effectively, it’s essential to employ thorough cleaning methods and potentially use specialised mould removal products.
The materials used in your home can play a significant role; porous surfaces like wood and drywall can retain moisture and become breeding grounds for mould if not properly treated. Ensuring that your home’s structure is resilient against dampness through proper insulation and sealing can significantly reduce the likelihood of recurrence.
