How to Repair Double Glazed Windows
It would be nice to believe that your double glazing is indestructible but the truth is that even uPVC frames degrade over time and problems like condensation, draughts and leaks can occur.
Fortunately, the majority of these issues can be repaired without the need to purchase a new window or door. This is especially true for foggy double glazing.
Draughts
Draughts are a typical double glazing repair issue and could be a sign of issues with the sealant. You can test whether your window is opening up to draughts by looking around where the sash and frame meet If there's a draught, this may be an indicator that the sealant has worn down. If you're not sure then consult a professional to perform a professional inspection.
You might be tempted by the idea of a DIY fix for your windows that are drafty however, it's best to leave the work to the experts. If you make the wrong repairs, they could harm your window and cause further issues in the future. A reliable tradesperson can ensure that work is done right and lasts for longer than you think it will.
It is typical for uPVC windows and doors to become difficult to open. This could indicate that the hinges or handles have been damaged or that the seals have failed.
In most cases, this can be corrected by adjusting the window sash, or replacing the hinges. But, this could be quite a task and requires the expertise of a skilled installer.
If your uPVC windows or doors are stuck in an open or closed position, it's crucial to have them fixed in the earliest time possible. This will help prevent further damage, and will improve the energy efficiency of your home.
Most double glazing comes with a warranty, typically for a period of 10 to 20 years or more. It is worth looking over the terms of your warranty and then contacting the company you bought the double glazing from if you find any problems.
Many companies offer the option to drill windows with mist and then insert a plug to draw out the moisture and make an entirely new seal. However, this is just a short-term solution and windows will likely mist up again in about six months.
This issue is typically caused by condensation that forms between the glass panes of your uPVC windows. It's a sign that the seals between the panes have failed and is not airtight, meaning that the argon gas used to insulate is no longer being held in place.
Condensation
Condensation is a concern with double glazing. It typically appears as a mist, or small droplets of water between the panes. It could be caused by a number of issues, including high humidity, low internal room temperatures, or the absence of air circulation. It could also be a sign that there is a problem in the seals or that the insulation isn't functioning properly.
It is possible for cold air to enter through the window, as well as warm air. This will reduce the energy efficiency. It is important to clean your double glazed windows regularly so that the glass stays clear. If this is not done, the glass will stay dirty and the seals may degrade over time. In some cases professional window cleaners will be required to keep your windows looking the best they can.
The good news is that there are ways to stop condensation from forming in double-glazed windows, for instance by installing trickle vents. This will control the temperature of your home and reduce the amount of water that collects on windows. You can also make use of window sills with a slope that allows water to flow out of the windows.
If you notice that your windows are starting to become cloudy or misty, it is important to contact the company who installed them as soon as possible. They might be able to reseal affected areas or replace the entire unit. In some cases it is covered under your warranty, so it is important to determine what's covered before you attempt a repair yourself.
A professional repair of your double-glazed windows repaired will save you a lot of stress in the long term, and will ensure the windows remain in good shape for as long as is possible. It's also a better alternative than replacing your windows entirely, as this can be expensive and might not provide any long-term protection.

If you notice water leaks around your windows, this is a clear indication that the seals are no longer effective and needs replacing. If left unchecked this can result in damage to your walls, ceilings and furniture. It can also lead to higher heating bills, as heat escapes through your windows.
If the leak is not too severe, it might be possible to repair this however, in more severe cases, it may be necessary to replace the whole double-glazed unit. It can be expensive, but is a much better alternative than letting water leak into your home.
Double glazing can become misty because of the gap between two panes. This allows moisture to get in, which then condenses during colder weather. This can lead to various issues, including draughts and condensation but it could also affect the energy efficiency of your windows dramatically.
Some companies will cut holes in your existing misted-up double glazing, and then inject chemicals which remove the fog & condensation from the window. Whilst this can be a cost effective solution it is not a permanent one. The holes drilled are often blocked by moisture again in about six months.
Another reason that misting can occur is because the frame of your windows moves in a slight manner over time, and this could break the seal. This again can be an underlying cause of draughts leaks and condensation.
Over time the gaskets used to seal your double-glazed windows can shrink or break. They can be replaced easily and at a lesser cost than replacing windows. This is a better choice for the environment and your wallet than buying new windows.
Double glazed windows are not impervious to damage, but they can develop faults from time to the point and some are repairable to a certain extent, however, it is essential that any repairs to double glazing are completed quickly, because a delay could cost you more in the long run. Double glazing that is damaged does not just affect your home's energy efficiency, but can be a security risk as well.
Damage
While it might appear as though double glazing is almost indestructible, the fact of the matter is that damage will inevitably develop over time. A lot of these issues can be easily fixed. Some double-glazed window problems can be more serious. They must be dealt with immediately, ideally by a professional who can provide repair services.
The appearance of condensation in double glazing is a serious problem because it indicates that the seal between the two glass panes is broken. This means that the heat you pay for is escaping and cold air is entering. This can cause significant discomfort and in extreme cases can lead to the development of mildew and mould.
Cracks and chips are signs of double glazing problems. The glass in your windows could break due to exposure to sunlight. It could also break by an impact or force like being thrown by a lawnmower as it cuts the grass, which is the reason double glazing should not be placed in an area that is prone to this.
A common issue that can become more prevalent with time is the difficulty of opening and closing windows and doors. This could be due to the weather or your frames might have shifted slightly over time.
A less important but frustrating issue that can be observed is the appearance of a dislodged air. This could be due to various reasons, but in the majority of cases, it means that the gas space between the glass has failed. This is usually a simple repair that involves replacing the sealed unit.
Draughty windows can be difficult to pinpoint where they are coming from However, a simple test can help. If you hold an incense stick or matchstick against the window frame and it moves, it will. This will tell you the presence of draft.
