Double Glazed Window Repairs
Double glazing is an investment that is worth it, but can be frustrating when it doesn't work. Luckily, the majority of issues are repairable and you don't have to replace your windows or doors.
Double glazed windows consist of two glass panels that are separated by a thin gap, which is filled with insulating gas, such as argon or krypton. This makes windows more efficient.
Broken panes
Double-paned windows are less likely to break than single panes of glass, however they are still susceptible to shattering or break. If a pane breaks in your double glazing, it's crucial to repair it immediately to avoid loss of energy and moisture.
You can select an immediate repair or a more intensive epoxy fix depending on the severity of your crack. A temporary repair will help prevent further cracks, and also keep out rain and cold air. A more extensive repair will strengthen the crack and provide an even stronger seal.
To replace a damaged double-pane windows, first remove the frame from the sash, and then set it on the table. Then, put a grid of duct tape on the pane to keep any glass pieces from falling off during removal. Once the tape is secured remove the double pane glass off of the frame. Then, clean the rabbet and grooves using a wire brush and vacuum or wipe them with a damp cloth. Remove the wood molding, if required and scrape away all putty or metal glazing points prior to installing the new pane. Then, apply a silicone caulk to the rabbet and grooves in order to ensure that the fit is secure.
If you're planning to repair the cracks in your window yourself, start by sanding the rabbet until it's smooth and clear of gunk or paint. You can also use a heat gun to soften any putty or glazing points. Once the rabbet is cleaned, a putty knife can be employed to press putty rope into position. Make sure the putty has an even thickness and is pressed against the glass and frame evenly.
If you want an option that lasts for a long time you can choose an epoxy repair instead of a replacement. This method requires more effort and takes longer, but it can be more appealing and will last longer than a temporary repair.
Condensation
Condensation is among the most frequently encountered double-glazed window issues, but it doesn't mean that your windows are defective. It's a good thing your windows are showing signs of condensation. This indicates that double glazing is working exactly as it should, keeping out the cold and keeping in the heat.
When you see condensation forming on the outside of your window, it is actually water vapor from inside of your home that has cooled and condensed onto the surface of the glass. It's a natural process that won't cause harm to your windows except if you let it sit on the surface long enough.
Internal condensation is often caused by too much humidity in the room or the low internal temperatures, causing cold surfaces, like windows, to attract moisture from the air that has a high dew point (the temperature at which water changes into a liquid). The steam from showers, kettles and hot pots as well as cookers can also cause a lot of humidity around kitchens and bathrooms.
Avoid hanging wet clothing close to windows, and make sure your uPVC frames are ventilated to avoid moisture buildup. For maximum energy efficiency, also make sure that double-glazed windows are constructed correctly and have the correct gap (6mm). You can also add one-way air vents to your windows to increase the insulation. If you're still seeing condensation, there is likely an issue with your seals or gaskets. This is a task that should be left to professionals.
Draughts
A draughty double-glazed window is an indication that the seal between the glass panes has failed and will need to be replaced. This will affect the insulation of your home and can result in an increase in your energy bills and therefore it is important to act fast when you notice the problem.

Smudging
Double-glazed windows consist of two separate panes, with the spacer or gas in between. This creates an effective seal to stop heat from escaping through the frame. They are a great way to save energy and decrease your carbon footprint. Double glazing may have many issues that can impact its performance and longevity. These include condensation, mist, and difficult to open or close.
If you are having trouble opening your double-glazed windows it could be because of the weather. It could also be a issue with the copyrights, or handles. Wiping them clean with cold water and lubricating them can solve the issue, however you must contact the company that you purchased windows from as soon as possible to get it fixed.

Foggy and fogged glass can be caused by condensation between the panes. It's usually a sign of faulty seals or an old double-glazing unit that needs replacing. It's a simple fix and you'll often get it done without the need to replace the entire window, which can save you money.

After the moisture has been removed, a new antifog coating is applied and the window is sealed. Sometimes, the window may require removal but, in most instances, it can be done from within the home.
Mist
Mist can be a big issue with older double glazing, particularly when it happens on the outside and inside of the windows. This is caused by an issue with the seal designed to keep moisture and air between the two panes. This seal is constructed during the production of double-glazed units by sealing the two panes using an airtight seal made of polysulphide or butyl around the edges and spacer bar. This seal is designed to prevent the window from leaking, and also provide insulation. If you have misted double glazed windows it can be difficult to take off and clean up, as you'll have to break through the seal in order to clean.
The issue with mists is that they allow moisture to penetrate, which leads to condensation between the glass panes. This is because there is a large difference in temperature between the internal and external surfaces of the glass. The moisture then gets trapped in the gaps and causes the appearance of a milky white. This can be very unsightly and is difficult to remove.
Some companies claim they can repair misting double-glazed windows by drilling holes in the unit and injecting chemical through the holes that absorbs moisture from the inside. But, this isn't an end-to-end solution to the problem and it is much more efficient to replace the whole double-glazed unit if experiencing misting.
The best method to avoid misty double glazing is keeping a good level of ventilation and regularly cleaning your windows. It is also recommended to use extractor fans in bathrooms and kitchens and wipe windows with a damp cloth to reduce the build-up 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 energy efficiency.
