Should You Repair or Replace Your Home’s Foggy Windows?

Dual pane windows have been around a long time. They’re far more energy efficient than traditional single pane windows, and more affordable than triple pane windows, so they’re incredibly popular. While dual pane windows are a reliable product, some older dual pane windows can develop problems. More specifically, some homeowners complain that their dual pane windows have become “foggy”. Knowing the cause of this problem and what can be done about it can help you take care of your windows. Here’s what you need to know.

The Anatomy of a Dual Pane Window

Dual pane windows consist of two panes of glass with air or an inert gas trapped in between. Well-constructed dual pane windows have special seals that prevents the air between the panes from escaping. The seal also prevents air and moisture outside the windows from entering the space between the panes.

What Causes Dual Pane Windows to Get Foggy

Dual pane windows can get “foggy” when the seal around the panes is compromised, thus allowing the gas to escape and moisture from the environment around the windows to enter the space between the panes. This can happen to dual pane windows as they age, especially if the windows were not made to withstand the test of time.

Cleaning the glass will not eliminate or wipe away the fog you see, because the fog is inside the two panes. If your windows are compromised and moisture has become trapped inside, no amount of wiping or cleaning the panes will wipe away that foggy film.

Not only are the windows unsightly, they have lost a major benefit of their energy efficiency. Once the air or gas can escape, you’re windows are much less energy efficient.

I’ve Got Foggy Dual Pane Windows. What Should I Do?

If your dual pane windows have become foggy, the insulated glass needs to be replaced. Unfortunately, this is a problem that can happen to some windows once they reach a certain age. Installing high-quality dual pane windows that have a warranty against seal failure can protect you from having this problem. The stronger the seal, the better your windows will fare over time.

If just one of your windows has developed this problem, get it replaced by a qualified window repair person. If more than one of your windows has become foggy, this is a problem that you may keep experiencing. If this is the case, window replacement may be in your future. Dealing with one window repair at a time as your window seals fail could become expensive and time consuming.

Have your windows assessed by a qualified window dealer and installer. Your window dealer will be able to assess the condition of your windows and give you a quote for replacement.
