How Can I Stop Condensation Forming on My Windows? Shark Innovative


Condensation on windows can be a frustrating and common problem for many homeowners. It occurs when warm air meets a cold surface, such as a window pane, causing water droplets to form. This can lead to issues like mold growth, damage to window frames, and even structural damage if left untreated. In this article, we will provide you with some useful tips and solutions to help you stop condensation on your windows in 2023.

Understanding the Causes of Window Condensation

Before we dive into the solutions, it’s important to understand the causes of window condensation. The primary factors contributing to condensation include indoor humidity levels, temperature differentials, and the quality of your windows. By addressing these factors, you can effectively prevent condensation on your windows.

1. Monitor and Control Indoor Humidity Levels

One of the most effective ways to stop condensation on windows is by monitoring and controlling indoor humidity levels. Invest in a hygrometer to measure the humidity in your home and aim for a range of 30-50%. To reduce humidity, use exhaust fans in high-moisture areas like bathrooms and kitchens, open windows for ventilation, and consider using a dehumidifier if necessary.

2. Increase Air Circulation

Poor air circulation can contribute to condensation buildup. To improve airflow, make sure your furniture or curtains are not blocking the vents. Use ceiling fans or portable fans to circulate air throughout the room. This will help prevent stagnant air from causing condensation on your windows.

3. Insulate Your Windows

Improperly insulated windows can create temperature differentials that lead to condensation. Ensure that your windows are properly sealed and insulated. Consider adding weatherstripping or caulk around the window frames to prevent warm air from escaping and cold air from entering. This will help maintain a consistent temperature and reduce condensation.

4. Use Window Treatments

Window treatments like blinds, curtains, or shades can help reduce condensation by creating a barrier between the cold glass and warm air. Choose window coverings that have insulating properties or consider using thermal curtains that can provide additional insulation.

5. Ventilate Your Home

Proper ventilation is crucial in preventing condensation. Make sure your home has adequate ventilation in areas prone to moisture, such as the kitchen and bathroom. Install vents or extractor fans to remove excess moisture from the air, reducing the chances of condensation occurring on your windows.

6. Use a Window Insulator Kit

If you have older windows or live in a particularly cold climate, you may consider using a window insulator kit. These kits consist of plastic film that is applied to the interior of the window frame. The film acts as an additional insulating layer, reducing heat transfer and condensation.

7. Check for Leaks or Damaged Seals

Leaks or damaged seals around your windows can contribute to condensation. Inspect your windows regularly for any signs of leaks or damaged seals. If you notice any issues, repair or replace the seals to prevent warm air from escaping and cold air from entering.

8. Consider Upgrading Your Windows

If you’ve tried all the above solutions and still struggle with condensation, it might be time to consider upgrading your windows. Look for energy-efficient windows that have low U-values and high condensation resistance ratings. These windows are designed to minimize heat transfer and reduce condensation.


Condensation on windows can be a nuisance, but by following these tips and solutions, you can effectively stop condensation in 2023. Remember to monitor and control indoor humidity levels, increase air circulation, insulate your windows, use window treatments, ventilate your home, use a window insulator kit if necessary, check for leaks or damaged seals, and consider upgrading your windows. By taking these steps, you can enjoy clear and condensation-free windows throughout the year.
