What Causes Window Condensation & How Do You Get Rid of it?

Table of Contents

Condensation on windows is a common issue faced by many homeowners. This phenomenon occurs when water droplets form on your windows due to high indoor humidity levels. Windows, lacking the insulation present within walls, are particularly susceptible to this effect. By identifying the factors that cause window condensation, you can better address and control it in your home.

Understanding Where Condensation Occurs

Condensation Inside the House

Condensation commonly appears on the inside of your windows. This indoor window condensation often results from high humidity levels inside your home. Everyday activities such as cooking, showering, and even having live plants near windows can increase humidity. When the moisture in the warm indoor air comes into contact with the colder surface of the window, water droplets form.

To manage this, it’s crucial to monitor and control your indoor humidity levels. Devices like humidifiers should be adjusted to maintain humidity at a comfortable level, ensuring that it doesn’t contribute to the problem.

Condensation Between the Panes

Sometimes, you might notice moisture between the double panes of your windows. This is an indication of a seal failure, which compromises the insulating properties of the window. If you encounter this issue, it’s likely time to contact a professional for a replacement. For residents of Johnson County, our products often include easy-to-remove sashes and may come with warranties that cover seal failures, depending on the manufacturer.

Condensation on the Outside

External window condensation is less common but can occur under certain conditions. In places like Kansas City, where humidity levels can be very high, condensation on the exterior of windows is more noticeable, particularly during certain times of the year. This type of condensation typically forms during morning hours on the outside of the glass and usually dissipates as the day warms up.

Misconceptions About New Windows

A common misconception is that installing new windows will completely eliminate condensation issues. In reality, new windows can sometimes highlight existing humidity problems because they are more airtight than old windows. This doesn’t allow moisture to escape, leading to condensation if indoor humidity is not properly managed.

Preventing Condensation

Preventing condensation involves a combination of managing humidity and ensuring good air circulation. Here are some practical tips:

  • Use dehumidifiers in highly humid areas of your home.
  • Ensure that vents in areas like kitchens and bathrooms are functioning properly and used during and after activities that produce steam.
  • Regularly check and maintain window seals and insulation to prevent moisture from seeping through gaps.
  • Consider weather stripping and storm windows as additional measures to control indoor climate.
