How to Repair a Double Glazed Window
Double glazing is an effective method to increase the insulation of your home and increase its energy efficiency. It could cause problems like condensation and draughts.
While replacing windows is the obvious solution to these problems however, repairs are often a much cheaper alternative. Let's take a look at the most popular double-glazed window repair options:
Broken Panes
The first step is removing the broken pane. Wear gloves that are thick, and put an empty cardboard box nearby to collect any fragments of glass that fall while you work. Wear a mask and eye protection because of the risk of lead in the frame. Utilize a utility knife to cut the glass surrounding the windowpane that has been broken. If nails or clips are holding the windowpane in the frame, use pliers to lift them out. After the glass is removed, remove any old putty or metal glazing points. A heat gun can be used to in softering the putty if you need to.
After the old putty has been removed, re-grout the grooves and apply the new silicone caulk with a silicone caulking gun. It's a good idea examine the fit of the new window within its frame before applying the final caulking. Make sure the grooves in the frame are free of paint, rust, or gunk, and are not too narrow to fit the window.
Replace the sash by a wooden molding to match the window frame. If the frame has begun to deteriorate it is simpler and more economical to replace the entire unit rather than just one pane.
In the past double-pane windows were two pieces of glass that were separated by a spacer, and then filled with gas or air to create an insulating gas. But in recent years, manufacturers have shifted to the use of insulated glass units (IGs) that are more energy efficient and resistant to seal failure. In a double-pane window with a failed IG, moisture from the air outside seeps into the gap and then condenses inside of the glass. This process eventually destroys the insulating properties that are present in the IG and leaves an unclean substance on the glass.
To fix a damaged IG glass, an expert in glass repair can replace the entire unit or can replace only the damaged surface of the glass. This can be costly and time-consuming, but it is the only option for fixing an issue with the seal that allows water to leak into the home. Selecting high-quality windows from a reputable manufacturer and having them fitted by a trained technician can help prevent future issues with the seals.
Misted Panes
The window frame is made up of two or more glass panes, each separated by an air-filled space. The air, which is usually filled with argon to increase energy efficiency and to keep warm air in it, helps keep cold air out. However, in some cases, these windows start to break down, and you will notice a hazy fog building up between the panes of the glass. You might think it's time to replace the entire window, but it's not as easy as just removing the broken pane and replacing it.
In most cases, a misted window indicates a problem with the seal between the two panes that comprise the glass. The condensation or mist means that moisture has entered, which damages the insulating qualities of the double-glazing. This is why it's important to be attentive to the care of your windows and keep them clean.
Condensation between the panes of your windows is a sign there's too much humidity in the home Therefore, it's essential to dehumidify as well as implement other measures to increase the airflow in areas where this happens often. If the condensation is only visible on one side of your window or between the panes, then you'll require having the seal replaced.
It is not possible to reseal double-glazed windows to bring back the original energy efficiency. If the seal is damaged the gap lets cold air to enter your home, and warm air to escape. This reduces the insulation power of your home, making it costlier to heat.
Some companies will drill holes in the window's pane of glass to drain the condensation. But it's an in-between solution that will unlikely last longer than six months. It's not recommended you try to do this yourself, since it could be extremely dangerous without the proper tools and experience. A double-glazing expert will use specific equipment to safely remove the condensation and install air vents that will aid in preventing the possibility of misting in the future.
Frame Damage
Double glazing isn't indestructible and even with the best of care problems can arise. Certain issues are minor and can easily be repaired. Other issues are more serious and will require a complete replacement. The owner of the property should make this decision, taking into consideration the benefits of double glazing and the value it can bring to the property.
If you are having trouble opening or closing your windows it could be caused by misting on the glass or an issue with the frame. It is recommended to repair your windows as soon as possible to prevent further damage to the double glazing.
Over time, the packaging that keeps the glass panes in their frames and stops them from moving can wear down. This can cause the glass sheets to move, which can rupture the seal and lead to misting. The space between the panes could also be misting, indicating that there is a breach in the seal.
A common issue is windows that have sagged over time and are difficult to open or close. This can be fixed by altering local window repair the mechanisms and hinges. Be aware that a lot of double-glazed windows are covered under a warranty. In this instance you must contact the company where you purchased your double glazing to find out what you can do.
You can repair double-glazed windows yourself, but it's usually recommended to speak with an expert for their expertise and knowledge. Professionals can identify the issue quickly and efficiently and perform the necessary double glazing repairs. You can also avoid voiding your warranty by not trying to repair your windows without the proper knowledge.
Weather Damage
Double pane windows are resistant to weather damage. However, if you live somewhere that is susceptible to icestorms hail, high winds and torrential rainfall windows and seals could be terribly damaged. The best way to make sure your windows stay in good shape is to regularly inspect them and fix minor dents and chips immediately you detect them.
Blown windows can be one of the more serious issues that you might encounter with double glazing. When there is a gap between the two glass panes air and moisture could get into your home. This is typically an indication of damage to the seals or an issue with the insulating material that is between your panes.
Condensation between the panes is a different issue that double-glazed windows could cause. This happens when the warm air inside your home is warmer than outside air. The difference in temperature causes the warmer air to expand, which can cause the window's seals to crack or weaken over time.
Foggy windows are also a common issue with double-glazed windows. This is a common problem that can be fixed without replacing the IGU. This is typically an indication that the seals between the window's panes require resealing.
You'll need to drill an opening between the window panes. It should be big enough to allow for the installation of an extended pipe cleaner or other long object with fabric on the other end. The cloth ends will be used to clean your windows clean and eliminate any excess condensate. This will help create a tight seal again and stop any further fogging of your double-glazed windows.
This is only a temporary fix for windows that are foggy. When it rains or there's a sudden increase in humidity, the condensation will return. If you are looking for a permanent solution you will have to replace the old IGU.
