Condensation on the outside of your windows happens when the weather changes and will likely disappear by itself. Exterior condensation actually reflects how well your windows are airtight. But condensation between panes of glass is a different story.   If you spot condensation between window panes, beware: over time the potential damage to your home such as rot, mold, and mildew can turn into an expensive headache. Read on to learn how you can tackle condensation inside your window panes to clear your view and safeguard your home. 

Causes of Window Condensation 

We’ve all taken a long shower, only to discover a foggy bathroom mirror waiting when we get out. That’s because the main cause of condensation is excess humidity. For windows, this can come from overly damp weather, bathing and cooking, or even running lawn sprinklers on a hot day.   Dehumidifiers inside your home can help dry the air, which will keep excess moisture off the inside of windows. Alternatively, a moisture eliminator can help draw unwanted moisture out of the air. Some moisture-eliminating products even contain pleasant scents, so if your home could use some fragrance, it’s a nice two-for-one.  If you’re looking for solutions on how to deal with window condensation in the bathroom, you might need to change out your bathroom fan. Keeping the bathroom fan running during a shower or bath can draw moisture out of the bathroom and vent it away from your home before the moisture can cause any damage.  However, if you follow these steps to handle window condensation and you notice your windows still have condensation between the panes, it could be a different issue.  

How Windows Develop Condensation Inside 

Condensation occurs when water vapor hits a cool surface and condenses, due to the natural temperature difference. There are two possibilities when water vapor seems to be condensing between your window panes.   The first is that the seal on double hung windows could be faulty, allowing water vapor inside and trapping it there. The second is that the desiccant, which absorbs moisture in between the panes of a double hung window, might not be able to keep up with the excess moisture.  You can troubleshoot window condensation and fix the problem when the panes are fogging because of environmental factors within your home. However, in most cases, there’s no catch-all solution for preventing condensation when it’s appearing inside of your windows.  For example, if you have an older home, the seals in your windows are likely held in place with caulk. Due to seasonal shifts in weather, the caulk can weaken over time. If you’re seeing condensation between panes of glass, it’s likely that your seals have failed. So, what do you do? 

How to Stop Condensation Inside of Your Windows 

If you have older windows where the seals are held in place with caulk, you may be able to replace the caulk and bolster the seal. This is normally a short-term fix because the window technician who repairs the seal can’t fully replace the gas that escaped from the window. Without the gas filling, your windows will become less energy-efficient, since gas-filled double pane windows act as a great insulator. This could also lead to a significant increase in utility bills.   Caulking seals won’t stop window condensation in the long run either. The best solution is to swap your old windows with energy-efficient replacement windows that have a tight seal. When you replace your windows with new ones, you won’t have to worry about condensation infiltrating your window panes, since the root cause is completely gone.  If you’re trying to get rid of the condensation inside of your windows, take and reach out today to get a quote on high-quality replacement windows from Window Nation.   Request a free quote on options for financing window replacement so you can safeguard your home and stay within budget.
