What Causes Condensation on My Windows?

Condensation on windows can be extremely aggravating for homeowners. It can cause a variety of issues, including mould growth on windows and damp patches on walls. However, condensation on windows can be easily reduced with a few simple solutions.

Condensation on double-glazed windows can be caused by several factors. Here are the most common causes and how to address them.

What Causes Condensation on the inside of Windows?

This is not a good thing if you’ve noticed condensation forming on the inside of your windows on a regular basis. Condensation can have a negative impact on your health, the durability of your windows, and the overall quality of your home.

Condensation is a common sign that your home has high humidity levels. There are several reasons why your home’s humidity levels are particularly high. But don’t worry, there are steps you can take to reduce condensation on your windows.

What Causes Windows Condensation?

Condensation on your windows can be caused by a variety of factors. To simplify matters, condensation occurs when warm air collides with cold surfaces (such as glass window panes). As a result, condensation is more common in the winter. There are numerous causes of condensation in the home, which we will discuss further below.

Condensation on Windows is caused by a lack of adequate ventilation.

Condensation could be caused by inadequate ventilation. This can result in warm air becoming trapped in your home. When it comes into contact with cold surfaces, condensation forms.

Common Causes

  • Cooking without using the extractor fan.
  • Keeping the windows closed or not using a fan while showering.
  • Lack of clear airflow through your home, such as blocked chimneys.

Quick Solutions

  • While cooking, turn on the extractor fan and open the windows.
  • While showering, open the windows and turn on the extractor fan.
  • Install air vents in high-risk rooms to naturally ventilate air out of the house.
  • Install new, modern windows that are designed to insulate and reduce condensation.

Condensation dependant on the Time of Year

Condensation is more common during the winter months. During the colder months, homeowners tend to heat their homes more. This means that humidity levels are higher, which causes more water to form on cold surfaces.

Quick Solution

  • Reduce humidity by opening windows. The disadvantage of this is that you must then re-heat your home when cold air enters.
  • Dry your clothes outside or in a tumble dryer rather than inside.
  • Purchase a dehumidifier to allow you to dry clothes indoors and control humidity levels.

Household Pets and Plants Have an Impact on Condensation

Excess moisture in the air can be produced by aquariums or fish tanks. Also, if any damp patches form near plants, this can be an indication that moist air is being produced.

Quick Solutions

  • Cover aquariums or fish tanks with appropriate lids to keep the warm air out.
  • Furthermore, keep tanks away from windows and leave enough space for air to circulate around them.
  • Plants should be moved outside or away from windowsills.

Condensation is caused by faulty or old windows.

If you notice condensation forming between the two glass panes of double glazing, the remedies listed above are unlikely to be effective. It indicates that the glass sealed unit and possibly the windows themselves need to be replaced.

Quick Solutions

  • If the existing windows are still functional, install new sealed units.
  • If the existing frames are in poor condition, it may be unwise to install new modern units in them. Check out our replacement windows and services, we’re more than happy to help.

How to Avoid Condensation

If you have high levels of condensation in your home on a regular basis, you can take a few preventative measures. Here are some expert tips to help you prevent condensation on your windows.

Every day, ventilate your home.

Proper ventilation is absolutely necessary to prevent condensation. Make it a point to open your windows for at least 20 minutes every day. This is especially important in kitchens and bathrooms, where warm and humid air can escape.

When cooking, keep the doors closed.

It is critical that you keep the bathroom or kitchen door closed while cooking or taking a shower. This may seem obvious, but it’s amazing how many people overlook it. By closing the doors in your home, you prevent humid air from travelling to different rooms. This simple prevention method prevents humidity from spreading throughout your home. It is an absolute necessity if you want to reduce condensation levels.

When possible, use extractor fans.

Extractor fans are an essential component of any property. And they are unquestionably there for a reason. By reducing warm and damp air, extractor fans help to reduce condensation levels in your home. As a result, whenever there is excessive humidity, it is critical to turn on the extractor fan. This helps to keep condensation from forming on your windows.

Try to keep your Windows Clean and Dry

Condensation on your windows can create black mould and rot to your timber frames over time. If you frequently have condensation, it is critical that you maintain your windows and walls clean. To avoid moisture problems, wipe down glass windows and timber frames with a clean, dry cloth. Please keep in mind that this is not a long-term solution. It can, however, help to keep the condition from deteriorating.

Maintain a Consistent Home Temperature

As previously stated, the temperature in your home can have a considerable impact on condensation levels. It can be tempting to bump up the heat in your home a little bit every day throughout the winter. However, this can result in uneven warmth, which can lead to condensation. Prioritize evenly heating your home. This will help to reduce condensation and should make a significant improvement.

Replace your windows.

Although all our solutions are beneficial, they only give a temporary solution to the underlying issue. Condensation will occur in your home if your windows are cracked, single-glazed, or simply not working as well as they once did. If you see condensation inside your windows on a frequent basis, it’s time to replace them.
