Double Glazed Window Repairs
Double glazing can be an investment that is worth it, but can be frustrating when it doesn't work. Most problems can be repaired and you don't need to replace your windows or doors.
Double-glazed windows are made up of two glass panes separated by a thin gap. The gap is then filled with an insulating gas, such as argon. This increases a window's efficiency.
Broken panes
While double-pane windows are more difficult to break than single-pane glass, they can still break or shatter. It is important to repair the broken pane of double glazing as quickly as possible in order to avoid moisture and energy loss.
Depending on the extent of the crack you may decide to use a temporary fix or opt for an intensive repair using epoxy. A temporary repair can keep cracks from spreading and keep out the cold and rain. A more extensive repair will strengthen the crack and create the seal with a stronger one.
To replace a double-pane damaged window, remove the frame and place it on an even surface. Install a duct tap grid over the pane in order to stop glass fragments from falling during removal. Once the tape is in place, pull the old double pane glass out of the frame. Next, clean the rabbet and grooves using a wire brush and vacuum or wipe with a damp cloth. Remove the wood molding if needed and scrape away all metal glazing points or putty before installing the new pane. Then, apply a silicone caulk over the rabbet and grooves in order to ensure that the fit is secure.
If you're trying to repair a damaged glass by yourself, begin by sanding the glass until it's smooth and free of paint. You can also use a heat gun to soften any putty or glazing points. After the rabbet is cleaned, you can use a blade for a putty to press the rope into position. Make sure the putty has an even thickness and is pressed against the glass and frame evenly.
If you are looking for the long-term solution then you could opt for an epoxy repair instead of a replacement. This method requires more effort and a longer wait time, but it can be more appealing and will last longer than a temporary repair.
Condensation
Condensation is one of the most frequently encountered double-glazed window issues, but it doesn't necessarily mean that your windows aren't working properly. The fact that your windows show condensation is a good sign because it means that your double glazing is performing what it is supposed to do, keeping the cold out and letting warmth in.
If you notice condensation appearing on the outside of your windows, it is actually water vapor coming from the inside of your home that has cooled down and condensed onto the glass's surface. It's a natural process and it's not likely to cause any damage to your windows unless you let it sit on the surface for too long.
The cause of internal condensation is usually a lack of humidity or low temperatures in the room. This causes cold surfaces, such as windows and doors, to draw in moisture with a high in dewpoint (the temperature at which water turns into liquid). The steam from showers, kettles, and hot pots and cookers can also create humidity in kitchens and bathrooms.
To avoid condensation, make sure not to hang wet clothes near your windows and always ensure that your uPVC frames have ample air circulation to stop the accumulation of moisture. To maximize energy efficiency, ensure that double-glazed windows are properly installed and insulated with the proper gap (6mm). You can also install one-way air vents on your windows to improve insulation. If you're still experiencing condensation,, then there's a problem with the gaskets or seals and this is definitely a job for a professional.

Smudging
Double-glazed windows are made up of two separate panes with a spacer, air or dense gas between them to create an effective seal that prevents heating from entering the frame. They're an excellent choice to save energy and reduce your carbon footprint. However, double glazing can have a range of issues that may affect its performance and longevity. These include condensation, mist and being difficult to open or close.
If you are having trouble opening your double-glazed windows, it could be due to the weather. It could also be a problem with the hinges or handles.

Foggy or fogged glass is caused by moisture in the panes. It's typically a sign that the seals are faulty or that your double-glazing unit needs to be replaced. It's a simple fix and you'll often complete the task without the need to replace the entire window, which will save you money.
To correct this issue A technician will drill tiny holes to let out any moisture between the glass panes and the remainder of the window. Once the moisture is removed, a new antifog coating is put on and the window is sealed. Occasionally, the window may need to be removed prior to this can happen but most of the time it is done from the inside of the home.
Mist
Double glazing that is older may have a mist problem particularly if it occurs both within and outside the window. This is caused by an issue with the seal that is designed to hold air and moisture out between the two panes. The seal is made during the production of double-glazed units by sealing both panes with an airtight polysulphide or butyl seal around the edges and a spacer bar. This seal is designed to keep the window from leaking and to provide insulation. If you have misted double-glazed windows, it may be a challenge to remove and clean up, as you'll need to break through the seal to clean.
The problem with mist is that it lets moisture to get in, which then results in condensation between the panes of glass. This is because there is huge differences in temperature between the internal and external surfaces of the glass. The moisture is then trapped within the spaces and gives the appearance of a milky white. This can be very unsightly and difficult to get rid of.
There are many companies who claim to be able to repair 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. But, this isn't an effective solution and it's much easier to replace the entire double-glazed unit if suffering from misting.
The best way to prevent misty double glazing is by maintaining a high level of ventilation and cleaning your windows regularly. It is also recommended to use extractor fans in bathrooms and kitchens and clean windows with an damp cloth to minimize the build-up of moisture. If you are unable to avoid the issue completely, we recommend replacing your double-glazed units with A-rated units to increase the efficiency of your energy usage.
