It’s a crisp, sunny fall day. You step to your kitchen window to take in the morning views when you notice that your windows have gotten foggy. The truth is that if you see fog in your windows, you have a problem. Fortunately, there are some measures you can take to fix the problem depending on how severe the fogging has become. Read on to find out how to fix fogged windows, as well as how to know when to replace them.
How to Fix Fogged Windows
What Causes Fogged Windows?
If you notice fogged windows in your home, you might think that it’s the temporary result of humid or damp weather. However, long-term window fogging is usually a problem with your window seals. Most insulated windows use two panes of glass, with space for air between the panes. In newer windows, the space between the panes has an insulating function, helping with your home’s temperature control and overall energy efficiency. But when the seal around your window’s insulated glass unit (IGU) begins to deteriorate, your glass can develop that telltale haze.
Causes of Seal Deterioration
There are a few primary factors that can cause your window’s seals to deteriorate:
- Water exposure: Your window’s perimeter seals can be vulnerable to water damage, especially after a flood or a heavy rainstorm.
- Age-related deterioration: Most high-quality windows have an expected lifespan of 15 to 20 years. After that time, you should expect to see some fog in your windows, which is the result of standard wear and tear.
- Excess heat: If you live in an area with high summer temperatures, don’t be surprised if your windows start to fog up a bit earlier than they might in a milder climate. Warm air physically expands the space between window panes, which can stretch the window’s seals. That can allow moisture to creep in over time.
- Window film: Similar to a car window tint, window film may be added to windows to add privacy or reduce glare. However, it can also cause additional heat buildup on the glass surface, which can cause seal failure. This is one of the most common causes of fogged windows.
How to Fix Fogged Windows
If your windows have reached the end of their expected lifetime, it’s likely time to think about replacement. However, if your windows are newer, you might consider replacing the insulated gas unit. This is cheaper than total window replacement, although it can be more complicated as it requires replacing the seal of the second pane of glass inside your insulated window.
When to Replace Your Windows
The reality is that all windows have a limited life expectancy. Depending on the age of your windows, total window replacement may save you time and money. If you’ve noticed that your windows are fogging over, you should first contact your window manufacturer to discuss whether your product warranty covers replacement. While your warranty may not apply in this scenario, it’s always a good idea to check in before investing in new windows.
While there are a few quick fixes for foggy windows, window replacement is often your best bet. This is especially important if you live in an area with frequent rainfall, as excess moisture around your windows can lead to mold growth. When in doubt, be sure to consult a window expert to discuss your options for fixing your foggy windows.
