Repairing double-glazed windows is notoriously difficult, especially for those who aren't window experts. There are a few things you can do if are prepared to tackle a more complicated DIY project other than simply taping cracks.
Misting can occur when the packaging that holds the glass sheets in place becomes worn. This is a common issue that can be resolved by an experienced professional.
Cracks

This could be costly for homeowners because it will reduce the efficiency of their home. It is crucial to get the crack repaired to prevent any further problems. This is also a a great opportunity to upgrade your window.
Most cracks in double-glazed windows are caused by thermal stress. This can be a result of sudden temperature changes, for example when radiators are switched on delivering a sharp burst of heat to the insulated gap between the window and the wall. Cracks may also appear on your windows as a result of seasonal factors such as sudden temperature changes overnight.
A poor installation is a common reason for double-glazed window cracks. If the space between the panes of glass isn't enough or the frames are poorly installed, it could cause them to expand at different rates, which can lead to cracks forming over time. This is a problem that can be avoided by choosing the right fitter for your new double glazing and checking customer reviews/testimonials.
If a double-glazed glass is cracked, it should be repaired as soon as possible in order to prevent further damage to the glass and the frame.

This could include filling in the cracks using a form of adhesive or putty that stops them from expanding further or breaking completely.
Condensation
If you see visible condensation, it's an indication that the double-glazed window has to be replaced or repaired. It's also a good idea to contact the company that you bought the windows from to find out whether they have a warranty that covers this type of issue.
Condensation can occur in double-glazed windows when the seal breaks, and the insulating gases between the glass panes cannot be retained. It is usually caused by air movement or humidity changes in the room, and is very uncomfortable. Gasket seals can be replaced without the need to replace the entire unit.
This is usually fixed by drilling a tiny hole in the glass and filling it up with desiccant. It is then re-sealed using an entirely new gasket to stop moisture from returning.
This is only temporary and does not prevent condensation from recurring in the future. It's also not as effective as a replacement window.
It's important to note that condensation on the exterior of double-glazed windows can be beneficial. This kind of condensation is caused when the air is warmer than the window and is a natural part of the process of thermal efficiency. If you notice condensation between the panes of your double-glazing then this is a sign that the seal has failed and the windows should be replaced.
There are a few ways to avoid condensation on your double-glazed windows. In the first place, it's a great idea to open a window or use an extractor fan when cooking or showering. It's also worth adding some shade to the area surrounding your window. This will keep the glass warm and will reduce condensation. This could reduce the energy efficiency of your home. It's also a good idea every now and then to wipe the frames with a damp cloth to remove any dirt or grime that could cause problems. You can also try spraying the frames down with a rust inhibitor to protect them from oxidation.
Broken Seals
A damaged seal on the double pane of your window can cause gaps that are visible between the glass, but an increase in your energy costs since it allows hot air to escape and cool air to in. In some cases water can get inside the house and cause mildew and mold.
Fortunately, there are many alternatives to repair the damage if your window seals have failed. You can employ an expert window technician to remove the damaged glass and then reintroduce argon gas or krypton gas into the space between the two windows. These gases are inert, odorless and clear gas that can function as an insulator and aid to keep heat inside during the winter and keep it out in the summer.
This is a more involved option, but it could be the most cost-effective solution for your window. A professional will need to disassemble the frame of the window to find and repair any cracks or gaps, then replace the glass pane, clean the frame, and then reassemble the frame.
Window seals typically fail due to age and exposure to weather. As seals get older, they become less flexible and eventually break. Excessive temperatures can also cause the seals to weaken over time. This is particularly relevant if the glass was not cleaned regularly which may leave deposits that affect the seal's flexibility.
Condensation between the glass and a foggy appearance are two of most evident signs that your window seals are failing. This happens when the window seals let humid air pass through, which later cools and condenses. This happens regularly and is often aggravated by weather changes and fluctuations in humidity levels outside.
Inspecting the seals of your windows regularly and making any needed minor repairs is the best method to avoid this. This will not only save you money on your energy bill however, it will keep the windows in good shape for longer, reducing the need for replacement.
Replacement
Double-glazed windows can increase the value of your home. They're not just excellent for reducing energy usage. Estate agents believe that homes with optimal double glazing appreciate in value, so maintaining your windows to ensure their efficiency is important for the longevity of your home.
Double-glazed windows comprise two glass panes that are separated by a gap which is typically filled with insulating gases such as argon or krypton. If these gaps become broken or damaged, they may start leaking and cause condensation between the panes. This means that your window isn't adequately insulating your home which can result in higher energy costs than usual.
The moisture that is spotted between the panes in double-glazed windows is often caused by air leaks or failed seal, meaning that it's time to replace the window unit. It's expensive to replace the entire window, but it is usually worth it when you consider the amount of energy bills that will be reduced with windows that are more energy efficient.
Replacing a double glazed window isn't a simple DIY job and should be left to experts, as it is extremely risky to handle broken glass. Before you can remove the IGU, you'll have remove the silicone or molding around the window frame, and also the wedge gasket. After you have removed the IGU and the frame is cleaned, you'll have to apply new sealant to the frames prior to putting in your replacement.
