How to Repair Double Glazed Windows
Double-glazed windows are usually covered by warranties of 10 or 20 years. Be upvc window repairs to check the warranty. Repairing your double glazing is less expensive than replacing it and could help you save energy and money too.
It is possible that the sealant between the glass panes has failed in the case of misted double glazing. This happens when the windows are worn or old. It could be expensive to replace.
1. Glass chipped or cracked
Double-glazed windows that have cracked or chipped can cause condensation to form between the two panes. In most instances replacing the glass unit is a must especially if one or both panes have been damaged. However, if the frame is in good condition, repairing a single glass pane can be a viable alternative.
Masking tape or duct tape are quick and easy methods to seal cracks. One strip of tape should suffice to close superficial cracks such as stress fractures caused by temperature differences. For more serious cracks, such as those caused by impact, it's recommended the tape be stretched across the entire length of the crack to ensure it will keep the glass in place.
A solvent-based glass glue can be another solution for an permanent fix. This is usually applied to both the inside and outer surfaces and then spread with a putty blade. This technique is more time-consuming than using masking tape however, it is more effective at stopping the cracks from spreading further.
If the cracks are very severe or have been present for an extended period of time it is possible to wait for a professional firm to fix the windows as this will likely result in a more durable finish. If the cracks don't seem to be severe enough and aren't causing water leaks, it may be best to opt for quick fixes. They can help keep the cost low.
Applying a two-part epoxy to the crack will make it more permanent. The glass's surface must be cleaned with a damp cloth, and then left to dry completely. Then, mix the hardener and resin in accordance with the instructions on the package and then apply it to the crack using a putty knife. After the putty is dry, you can paint the frame and the putty to create a seamless design.
2. Water Leaks
If your double glazing has been leaking or you've noticed condensation between the glass panes, both of these problems can usually be addressed without the need to replace your windows. This is because the issue isn't in the uPVC, aluminium or timber window frames but rather in the IGU, or insulated glass unit (IGU) which is located between them.
The IGU is made up of two glass sheets separated by a spacer, and filled with an insulation material. It's like a sandwich made from glasses. The gap must be airtight to stop cold air from getting into your home and to keep your home warm. Unfortunately, as time passes and through various temperatures, the seals in the IGU may weaken and cause leaks.
You can identify water leaks by looking for water on the sill or window frame, discoloration and an unpleasant smell. If you notice any of these, it's important to seek out an expert for immediate repairs.
If you see condensation on your double-glazed windows, this is most likely to be the result of high levels of humidity in your home. This is a normal phenomenon that occurs in winter, but is not the result of faulty double glazing, however frustrating it may be.
If you see water between the glass panes of your double-glazed windows, it indicates that the IGU is not performing as well as it should. Moisture between glass panes not only looks ugly but also affects double glazing's efficiency since it is no longer able to keep cold out and warm in.
There are a variety of ways that this problem can be solved, but it's generally best to leave it to the experts. They will drill small holes in the affected pane of the glass insulated unit. They then inject or pump in an desiccant in order to get rid of the moisture and then use a special anti-fogging solution to prevent condensation from returning. They may then inject hot air into the hole to further dry it out.
3. Draughts
The airtight seal double-glazed windows have prevents condensation from building up between the window panes however, over time, the seal may begin to fail. When this happens, you could detect a cold draft entering through the window or through the door. This can be a nuisance and cause a loss in energy efficiency. If your window is draughty it is recommended to contact repair services immediately to repair the seal.
Double glazing is a window type that includes two glass panes within frame constructed of uPVC or aluminum. The principal element of a double-glazed window is referred to as an insulated glass unit (IGU) which is made up of two sheets of glass separated by an air gap that's filled with an insulating gas. This forms an insulation gas-filled "sandwich" of glass that helps keep your home warm.
Modern double-glazed windows are very likely to not break or be damaged, however they require attention as a way to protect your investment.

Haze is among the most frequently encountered issues with double glazed windows. It is caused by moisture trapped between the two glass panes typically because of a damaged seal. It can be difficult to get rid of haze, regardless of whether it is due to condensation or a problem with the window frame. However, it is possible to fix misted double glazed windows without replacing them.
An easy solution to a problem of this kind is to utilize a dehumidifier or desiccant in the form of a packet. If you're experiencing a serious or long-term problem it is best to talk to an expert.
Despite being extremely durable frames made of uPVC, they can degrade over time, particularly in the case of a particularly cold or warm day. This is not unusual, but it can cause issues like a stuck or stiff window. Engaging a UPVC specialist is usually the best way to address the issues.
Some companies will drill holes into the window and then insert desiccants to draw out any moisture. This is a great solution, and it is less expensive than replacing. It is important to remember that the hole will need to be plugged again after six months, and moisture could return when there's a crack in the seal elsewhere in the window.
Another way to repair a problem with haze is to get rid of it with a vinegar and water mixture, or by using a commercial product specifically designed to deal with this problem. This is a more intricate process than simply drilling holes in the window and putting in a desiccant, but it can be successful and doesn't require a replacement.
