One of the reasons that double-paned windows are so energy efficient is that they provide additional insulation with a layer of gas between panes. Unfortunately, if the window seal is broken, this gas can leak out. Can gas-leaking windows be repaired?
Can Gas-Leaking Windows Be Repaired?
Have you ever had to deal with condensation ruining the view through your double-paned window? You can clean them inside and out, but the moisture and fog will still remain trapped between the panes. Not only is this irritating, but it’s a sign that your window seal has failed. So, how does this happen, and how can you fix it?
Why Is There Gas in My Window?
Before we get into the repairs, let’s stop and talk about why double-pane windows work the way that they do. You might be surprised to learn that there’s more to your windows than just wood and glass. Believe it or not, most double-paned windows are actually filled with inert gas trapped in between the panes of the window. This allows double-paned windows to provide added insulation without compromising your view.
However, if the seal that holds the double-paned window together fails, that inert gas can seep out of the window. If you’re seeing fog, it’s probably because that gas has been replaced by humid air. There are also other signs of window seal failure that a homeowner should keep an eye out for:
- Rubber-looking spacer material that has moved into the viewable area
- Cracks in the window panes
- Rainbow or other distorted color markings between the two panes
Windows that receive a lot of sunlight are sometimes at risk for window seal failure due to the way sunlight can make the temperature of the window fluctuate. However, many window seal issues result from age, aftermarket film tints, modifications, faulty installation, or failed repair efforts. In other words, if you aren’t sure what you’re doing when it’s time to fix or install a window, it’s a job better left to the professionals.
If you’re a window professional, or just a confident home handyman, there are some things you can do about a gas-leaking window. Just keep in mind that a quick fix isn’t going to provide the solution you need for an improperly installed window. Depending on why the failure occurred, a window replacement might still be in your future.
How Can I Get a Gas-Leaking Window Repaired?
If you’ve determined that your window is leaking gas, it’s time to call in a window professional. If the window is still under warranty, contact the manufacturer and describe the problem. They should be able to send someone out to inspect it and provide a repair that will keep the window within its warranty. If the window is not under warranty, any qualified window technician should be able to assist you.
When your window technician arrives, they will most likely examine the window for any damage. If they determine the window is basically sound and the problem is with the seal, a new insulated glass unit (IGU) can be ordered to replace the leaking panes. Once the window is all sealed up, the problem is solved! However, if the window is somehow damaged beyond possible repair, your best option is a new window or door replacement.
If you don’t have the time or budget for a full window replacement, defogging is also an option. To defog a double-pane window, a window technician will drill a small hole in the corner of the window and inject a drying chemical into the space before sealing it back up. While this will not solve your problem with your window seal, it is a workable temporary solution. (Note: American Window Company does not currently offer this service.)
