Understanding Insulated Windows

Let’s start by discussing what an insulated window is. Also known as insulated glazing or thermal windows, these windows feature two or three panes of glass with space between them. This space is filled with inert gases like argon or krypton, which are less heat-conductive than air, to provide extra insulation. When the seal that protects the window edges breaks, the gases can escape, and air and moisture can enter, causing fogginess or condensation between the panes.

Signs of a Damaged Window Seal

Now, how can you tell if your window seal is damaged? Look out for these tell-tale signs:

Condensation or fogginess between the panes that can’t be wiped off.
Difficulty seeing through the window.
Loss of energy-saving capacity.

If you’ve noticed any of these symptoms, it’s time to take action and fix that window seal!

Options for Fixing (or Living With) a Broken Window Seal

Check the Warranty: If your window is still under warranty, this may be the easiest solution. Contact the manufacturer to see if the seal can be replaced at no cost to you.
Fix the Condensation Problem: Consider hiring a defogging service or using a DIY defogging kit to remedy the fogging between the panes. This process doesn’t involve removing or replacing the window, so all materials stay in place.
Replace the IGU or the Window: You can hire a professional or do it yourself to replace the glass unit without replacing the entire window and frame. Glass replacement companies offer replacement IGUs that can be installed in existing window frames.
Leave the Window Alone: If you can live with the occasional fogginess and you’re in a mild to moderate climate, ignoring the failed seal may be an option. In some cases, the impact on your heating or cooling bills may be minimal.

Tips for Preventing Broken Window Seals

Avoid using heat guns or pressure washers near your windows, as these can damage the seals.
Ensure proper installation to prevent seal failure.
Regularly inspect your windows for signs of damage.

When to Call a Professional

If you’re not confident in your DIY skills, it’s best to call a professional to defog or replace the IGU within the frame. They have the experience and tools to get the job done right. While there are DIY kits available, they can be challenging to use successfully.

Costs and Considerations

The cost of fixing a window seal can vary depending on factors like window size, damaged panes, or trapped moisture. A window specialist may charge between $70 and $245 or more for the repair. Keep in mind that fixing the seal is more complicated than simply adding a rubber seal replacement. If your window isn’t too old and the frame is in good shape, you may be able to swap out old and new IGU panes.

In conclusion, a failed window seal doesn’t have to be a cause for panic. By understanding the signs of a damaged seal and knowing your options for fixing it, you can make an informed decision on how to proceed. Whether you choose to DIY or hire a professional, restoring your window’s insulation can help maintain your home’s energy efficiency. So don’t let a broken seal dampen your day—take action and enjoy clear, fog-free windows once again!
