Why Do My Pella Windows Have Moisture Around the Edges?

Moisture on Windows

• Since windows are one of the barriers between the outside and the inside of your home, problems related to temperature, moisture and humidity can often manifest themselves on the surface of the windows, whether Pella or any other brand. Ice, frost, condensation or even dripping water on windows can all indicate that there is an extreme differentiation between the humidity in your home and that outside of your home.

Addressing the Problem

• Excess moisture can easily make its way inside homes that are not very well sealed. So to address the problem of moisture in the home, use caulk or weather stripping to seal up any cracks or crevices that could allow moist air inside. Inspect your insulation as well; if it has become waterlogged due to a plumbing or roof leak, it could be allowing excess moisture inside. If the Pella windows are double-paned, one of the panes may have become damaged and be allowing excess moisture into your home.

Preventing Future Moisture Problems

• All of these steps and more can help improve your home's air exchange rate and the ability of your home to remove moist air and draw in dry, fresh air from the outside. Increasing this air exchange rate can go a long way toward helping to reduce moisture and humidity problems. Occasionally, though, even these steps are not enough to prevent moisture problems. For extreme moisture and humidity problems, you may need to install and use electric dehumidifiers in the home.

Other Considerations

• Excess moisture raises relative humidity, which quickly increases discomfort for the people living in your home. Moisture in the air and on surfaces also creates the perfect growth conditions for molds and mildews that can damage your home and cause health problems for your family. Moisture in hidden areas, such as underneath floors, behind walls and in attics and crawlspaces can also go unnoticed until it has caused substantial and costly structural damage to your home.
