Solving exterior window condensation in spring and summer

Person sealing windows with weatherstripping to prevent exterior window condensation at home.

In warmer months, you’ll be more likely to find condensation on the exterior of windows than on the inside. While it’s usually less concerning than interior condensation, it can still be an annoyance or lead to mold growth along your window’s exterior frame and sill. Here’s how to prevent it:

Seal your windows with weatherstripping. Adding weatherstripping around your windows creates a tighter seal, reducing drafts. This can help maintain consistent indoor temperatures, which minimizes the chance of exterior condensation forming. But keep in mind this may only be a temporary fix if your window is very drafty or if it’s a window you open often, like a sliding window.

Invest in energy-efficient windows. Upgrading to energy-efficient windows with insulated glass or low-emissivity (Low-E) coatings can reduce the amount of heat transfer, keeping hot outside air from encountering cool glass and reducing condensation.

Maintain a balanced indoor temperature. Avoid setting your air conditioning to a very low temperature, as this can create a more significant temperature difference between the glass and the outside air, leading to condensation.
