How to Repair a Double Glazed Window

Double glazing is a great method to increase your home's energy efficiency as well as insulate it. It can have problems like condensation and draughts.

While replacing windows is the obvious solution to these issues but repairs are often a much cheaper option. Let's look at some of the most commonly used solutions for repairs to double-glazed windows:

Broken Panes

The first step is to take off the broken pane. Wear gloves that are thick, and keep a box of cardboard nearby to catch any pieces of glass that fall while you work. Wear a mask and eye protection because of the risk of lead being in the frame. Use a utility blade to cut the glass surrounding the broken windowpane. Make use of pliers to take out any nails or clips that are securing the windowpane. Once the glass is removed, scrape off any old putty and glazing points. A heat gun can help soften the putty if necessary.

Once the old putty is removed then re-grout the grooves, and apply new silicone caulk using a silicone caulking gun. It is a good idea to test the fit of the new window inside its frame before applying the final caulking. Make sure the grooves are clean of any gunk, rust, or paint and that they are not too narrow for the windowpane to fit into.

Replace the sash after that with a wood molding to match the frame. If the window frame is in poor condition it might be simpler and more cost-effective to replace the entire window unit instead of one pane.

In the past, double-pane windows were just two pieces of glass separated by a spacer and then filled with air or an insulating gas. In recent years, manufacturers have changed to insulated glass units (IGs) which are more energy efficient and resistant to failure of seals. In windows with a failing IG the moisture from the outside seeps through the gap and condenses inside the glass. This process eventually erodes the properties of insulation and leaves a film of haze on the glass.

To repair a damaged IG, the glass repair expert can replace the entire unit or can replace just the broken surface of the glass. This can be a time-consuming and costly process, but it is the only option to fix a damaged seal that allows water to enter the home. Installing high-quality windows by a professional with experience and purchasing windows from a reputable business will help prevent the possibility of future seal issues.

Misty Panes

The window frame is made up of two or more glass panes that are separated by an air-filled space. The air, which is typically filled with argon to improve energy efficiency and to keep warm air inside, helps keep cold air out. However, in some cases, these windows begin to crack and you'll see a hazy cloud building up between the panes of glass. It may seem like it's time to replace the entire window, but it's not as simple as just removing the broken pane and replacing it.

Condensation in the panes of your windows is a sign there's a high level of humidity in your home Therefore, it's essential to dehumidify as well as take other steps to improve ventilation in the areas where this happens frequently. If the condensation is only visible on one side of the window, or is visible between the glass panes It means there is a problem with the seal, and you'll need to get it repaired.

When the seal breaks down, the gap will allow cold air to enter your house and warm air to escape. This can reduce the insulation power of your home which will make it more expensive to heat.

Certain companies offer to drill holes into the panes of your window's exterior to remove the condensation. But this is an in-between solution that will unlikely last longer than six months. You should also avoid trying to do this on your own because it can be extremely dangerous if you do not have the right tools or experience. Double-glazing professionals use specialist equipment to safely remove the condensation and replace it with new air vents that should stop future misting.

Frame Damage

Even with the best care double glazing can develop problems. Some faults are minor and can be fixed. Some are more serious and will require the replacement of the entire window. The owner of the home must make this choice, taking into consideration the benefits of double glazing as well as the value that it adds to the property.

If you have trouble opening and closing your windows it could be caused by misting or an issue with the frame. If this is the case, you need to have your windows fixed as quickly as possible to prevent further damage to your double glazing and to stop water entering the insulated gap.

As time passes, the plastic that holds the glass sheets in their frames and prevents them from moving may wear down. This could cause one or both glass sheets to shift slightly, which breaks the all-important seal, which can cause misting. The insulating space between the panes can also mist up, indicating that there is a broken seal.

Another common issue is that the windows have begun to shrink over time and make it difficult to open and close them. This is usually corrected by altering the hinges or mechanisms.

Blown windows are one of the most significant issues that you might encounter when you have double glazing. When a gap appears between the two glass panes air and moisture could seep into your home. This is usually an indication of deterioration in the seals or a problem with the insulating material between the panes.

Condensation between the panes is another issue that double-glazed windows could cause. This is due to the warm air in your home being warmer than the cooler air outside. The difference in temperature causes the warmer air to expand, which can cause the window's seals break or weaken with time.

Foggy windows are also a common problem with double-glazed windows. The good thing is that this is an issue that can be resolved without replacing the IGU. This is usually an indication that the seals between the windows must be replaced.

You'll need to make an opening between the window panes. The hole should be large enough to allow you to insert a long pipe cleaner or any other long object that has fabric on the end of it. You will then need to use the cloth to clean your windows and remove any excess condensation. This will create an even seal and stop future fogging.

This is temporary solution for windows that are foggy. Condensation will return as soon as it rains or there is an increase in humidity. If you want a permanent solution, you will need to replace your IGU with a new one.
