How Does Condensation Get On The Inside of a Window?

Condensation forms when warm, moist air touches a cold surface. In homes, this often occurs when warm indoor air comes into contact with cold windows. The moisture in the air then condenses on the glass surface, leading to droplets of water on the inside of the window.

There are several reasons why your home may be generating excess moisture and causing condensation on windows:

Cooking and boiling water on the stove;

Drying clothes indoors;

Bathing and showering;




How Do I Stop Condensation On My Windows?

Fortunately, there are many ways to reduce condensation buildup on your windows. Here are some tested and proven methods to keep your home free from condensation:

Use a dehumidifier

A dehumidifier can be a helpful tool in keeping the air in your home dry. This device works by removing excess moisture from the air, reducing humidity levels and preventing condensation.

Keep your home ventilated

Good ventilation is essential for reducing the buildup of moisture in your home. You can achieve this by regularly opening windows and doors, especially when you are cooking, bathing, or showering.

Install extractor fans

Extractor fans can help remove excess moisture from your home’s humid spaces such as bathrooms and kitchens. Make sure to turn them on when you are showering, bathing, cooking, or drying clothes indoors.

Limit the use of humidifiers

Although humidifiers can be used to add moisture to your home’s air, they can cause excess humidity levels, leading to condensation on windows and other surfaces.

Use double-glazed windows

Double-glazed windows are designed to provide better insulation than single-glazed ones, preventing the buildup of condensation on windows, on the inside. These types of windows are highly recommended for homeowners in the UK, especially during the colder months.

Install trickle vents

Trickle vents are small openings installed at the top of your window frames that allow for the steady flow of air, resulting in minimal condensation. These vents can be a useful addition to your windows, especially if your home does not have adequate ventilation.

How To Stop Condensation On Windows Overnight

If you’re experiencing condensation buildup only at night, you may need to take specific measures to remedy the situation. Here are some tips to help prevent night-time condensation:

Open a window

Opening a window slightly at night can help reduce humidity levels and improve ventilation. Ensure, however, that you have secure locks and that the opening is not large enough for intruders to enter.

Leave your bedroom doors open

A closed bedroom can trap moisture, leading to condensation. Leaving your bedroom door slightly open at night allows for better airflow, which can reduce the buildup of condensation.

Use a dehumidifier

If your bedroom still has excessive moisture levels, you may want to consider using a dehumidifier at night. This device will help keep the air in your room dry, reducing the chances of condensation on windows.

What Can Be Done To Prevent Condensation Inside Double Glazing Windows?

Even though double-glazed windows are designed to prevent condensation buildup, they are not entirely condensation-proof. Here are some tips to help prevent condensation inside double glazing windows:

Keep windows clean

Dirty windows can cause water droplets to form on the inside, making it harder for your windows to insulate. Regularly clean your windows using a mild detergent solution and a soft cloth.

Heat your home

Warmer indoor temperatures help reduce the difference in temperature between the windows and the inside air, thus decreasing the buildup of moisture.

Renovate windows

Old double-glazed windows can collect water droplets between the glass panes, making it impossible to clean. Consider renovating your windows to prevent this from happening.

Remove built-up moisture

If you have persistent condensation buildup, you can remove the moisture by using a cloth or a sponge to absorb the droplets.

It’s common problem for homeowners in the UK. You can eliminate the issue entirely or reduce it to a manageable level. Always keep your home ventilated, use dehumidifiers, and consider upgrading to double-glazed windows to minimize the buildup of moisture.

Prevent damage to your windows, sills, and frames. Keep your home looking great for years to come.
