Double Glazed Window Repairs
Double glazing is a great investment for your home, but it can be a pain when it doesn't work properly. Fortunately, most issues are repairable and you don't have to replace your doors or windows.
Double-glazed windows consist of two glass panes separated by a thin gap. The gap is filled with an insulating gas like the gas argon. This increases the efficiency of a window's heating.
Broken panes
Double-pane windows are resistant to breaking than single-pane glass, they are still able to crack or shatter. It's important to fix the broken pane of double glazing as soon as possible to avoid loss of energy and moisture.
Depending on the degree of the crack, you may decide to use an interim fix or opt for an intensive repair using epoxy. A temporary repair can help stop further cracks from occurring and keep out the cold and rain. A more extensive repair will strengthen the crack and will provide an even stronger seal.
To replace a double-pane damaged window, take the frame off and place it on an even surface. Install a grid of duct tape over the pane in order to stop glass fragments from falling during removal. Once the tape is in place then pull the old double pane glass off of the frame. Then you can use a wirebrush to clean the rabbets and grooves. You can also vacuum or wipe them with a damp cloth. If needed, remove the wood molding and scrape away all metal or putty prior to installing the replacement pane. Apply silicone caulk into the grooves and rabbets to ensure a snug fit.
If you're looking to fix damaged windows yourself, start by sanding the rabbet until it's smooth and free of paint or gunk. You could also use a heat gun to soften any putty or glazing points. Once the rabbet is cleaned the putty knife can be used to push a rope of putty into position. Make sure the putty is uniform in thickness and press against the glass and the frame in a uniform way.
If you're looking for a long-term fix, an epoxy repair is a better choice over replacing. This option is more costly and will require a longer wait time, but can be more attractive. It will also last longer than the temporary fix.
Condensation
Condensation can be a common issue for double-glazed windows however, it doesn't mean that they are defective. It's good to know that your windows show condensation. This means that your double glazing is working as it is supposed to, keeping out the cold and retaining the heat.

The reason for internal condensation is usually too much humidity or low temperatures in the room. This causes cold surfaces, such as windows, to attract moisture that is high dewpoint (the temperature at which water turns into a liquid). It is also commonplace in bathrooms and kitchens due to steam from showers or kettles and hot pots and pans that are used for cooking.
To prevent condensation, try not to hang wet clothing near your windows and always ensure that your uPVC frames are able to provide ample air circulation to avoid the build-up of moisture. You should also make sure that your double-glazed windows are properly insulated and fitted, with the correct gap (6mm is best) for optimum energy efficiency. You can also add air vents that are one-way on your windows to improve insulation. If you're still getting condensation, there's probably an issue with gaskets or seals and this is definitely an issue that requires the expertise of a professional.

Smudging
Double-glazed windows comprise two separate panes, with a spacer, air or dense gas between them to make an effective seal that blocks heat from passing through the frame. They are a great way to conserve energy and reduce the carbon footprint of your home. Double glazing may have many issues that can impact its performance and longevity. These include fog, condensation, and being difficult to close or open.
If you're having trouble opening your double-glazed windows, it could be due to the weather. It could also be due to a problem with the hinges or handles.

Once the moisture is removed, a new antifog coating is put on and the window is sealed. Sometimes, the window may require removal however, in the majority of cases, it can be done at home.
Mist
Double glazing that has been in use for a long time may have a mist issue in particular when it happens both in and out of the window. This is caused by an issue with the seal designed to prevent air and moisture between the two panes. During the manufacture of double-glazed units the seal is made by sealing both panes using an airtight polysulphide or butyl seal around the edges of the glass and spacer bars. This is designed to provide insulation and keep the window from being leaking. If you have misted double-glazed windows, it may be difficult to take off and clean, since you'll have to break the hardened seal to clean.
The issue with mists is that they permit moisture to enter, which leads to condensation between the glass panes. This is due to huge differences in temperature between the external and internal surfaces of the glass. The water is then absorbed within the spaces and gives the appearance of a milky white. This can be extremely unsightly and is difficult to get rid of.
There are several companies that claim they can fix your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes. Then, they absorb the moisture from within. This isn't an end-to-end solution and it's much easier to replace the entire double-glazed unit.
It is important to keep your windows clean and well-ventilated regularly. It's also recommended to use extractor fans in bathrooms and kitchens and wipe windows with an damp cloth to minimize the accumulation of moisture. If you're not able to completely avoid the issue, we recommend replacing your double-glazed units with new A-rated units to increase the efficiency of energy.
